Episode 1: Dipper and Mabel vs. the Future
Mabel waking Dipper up in the attic of the Mystery Shack. Having a pair of google-eyes on her chin, Mabel talks as "Mr. Upsidedownington," leaning over Dipper, who tells Mabel that she hasn't done that since third grade. Mabel reminds Dipper that their 13th birthday (which is August 31, the last day of summer) is only one week away, which Dipper had hardly realized. Suddenly, Soos and Grunkle Stan enter the room, with both of them talking about events happening in the near future. Soos remarks on how the future is coming for them all and everyone echoes him.

Dipper and Mabel head downstairs to begin planning, with Mabel believing that the big birthday party will be thrown at the Mystery Shack. However, Stan says they are not allowed to have another party at the Shack after the events of "Scary-oke." Soos recommends the Gravity Falls High School gym as a good place to have the party. The twins are about to head there together, but Ford Pines calls Dipper over, saying his face is on fire.

Dipper runs to help Ford, but he has everything under control. He then shows Dipper something extremely urgent - the fact that the interdimensional rift is cracking. If Bill Cipher manages to get the rift when it's completely cracked, he would unleash a catastrophic event that will unravel reality. Ford had dubbed this event called Weirdmageddon. Dipper is hesitant, wondering what he should do with Mabel and his birthday party. Mabel walks in, telling Dipper that he can go on his quest with Ford, and saying that the two of them can stay in touch using walkie-talkies. Ford runs off, telling Dipper to hurry. Dipper psyches himself up for his first mission with Ford and promptly walks into the doorframe before actually heading out the door. The two of them go on a quest to patch the rift, and Ford will explain the exact nature of his plan along the way.

Mabel and Soos head to Gravity Falls High School, where Lee and Nate are rearranging the letters on the school's sign. The two go into the gym, finding lines of despondent high-schoolers. Mabel finds Wendy and asks her what's happening. Wendy explains that it's registration day and that no one is happy about it. Mabel is confused, thinking high school is fun and song-filled, just like on TV. Wendy says that TV's portrayal is a lie and that if Mabel can avoid growing up, she should. Everyone in the gym promptly laughs at Wendy as the man in charge of registration mispronounces her name, leaving Wendy embarrassed.

Mabel exits the gym, becoming depressed. She tries to radio Dipper via walkie-talkie, saying that they can have the party at gym but the future of high school is becoming bleak. Dipper is unable to respond, as there's too much interference on his end. Soos sits next to Mabel, suggesting that she delivers invitations to her friends. As the two drive away, Mabel sees the high school sign has been changed to read "NO ESCAPE."

Ford and Dipper reach their destination - a large hill overlooking the floating cliffs of Gravity Falls. Ford remarks on how the cliffs look seemingly unnatural and oddly shaped, and Dipper realizes what Ford means when he holds a UFO keychain in front of him. Ford reveals to Dipper that the valley of Gravity Falls was created millions of years ago, when a spacecraft of some kind crash-landed into the area, creating the shape in the cliffs. The spacecraft is now buried under the town. Ford has had a lot of experience with the craft, having raided its parts to build the universe portal. He assures Dipper that all of the aliens inside have "probably" been dead for millions of years. Ford opens a hatch on the hill using a magnet gun, and the two head down it, into the depths of the spacecraft.

Inside the spacecraft, Ford and Dipper walk around, attempting to search through its halls for the adhesive. The two pass through the craft, which is dominated by huge open spaces that contain mysterious message written in code, ruined machines, and alien skeletons. Ford tells Dipper that the spacecraft contains an alien adhesive powerful enough to seal the crack in the rift, and their job is to look for it. Ford uses his magnet gun to slide down several metal columns in order to head further into the craft, but Dipper is hesitant to follow him. He uses the magnet gun, but it ends up attaching him to the ceiling instead of pulling him down.

Meanwhile, Mabel goes to see Grenda and Candy in the hopes of giving them invitations to the birthday party. Unfortunately, Grenda will be visiting Marius von Fundshauser in Austria, and Candy will be at music camp. Mabel is sad that neither of her best friends will be able to come to her party or wish her goodbye when she leaves for home. They share a hug, and Mabel leaves. She tries to radio Dipper, but he doesn't answer.

As they search, Ford offers to make Dipper his apprentice in learning about the secrets of Gravity Falls. Dipper is unsure since he would have to part with Mabel when she returned to California. As he speaks, he uses the magnet gun on one of the alien plates, revealing the adhesive. They are about to leave with the adhesive when suddenly, two prison droids appear. Ford tells Dipper that they focus on adrenaline, and if you are not scared, they will not hurt you. He destroys one of the droids with the magnet gun, but Dipper is unable to keep his fear in check, and the other droid attacks him. Ford pushes him out of the way, but he is injured and captured by the droid. Dipper chases the droid through the saucer. The droid puts Ford into a different, ship-like droid, that will take Ford far away. As the little ship prepares to take off through a hatch in the saucer, Dipper attaches himself to the ship with the magnet gun. The ship takes off, streaking over the town and destroying the water tower as Dipper desperately tries to disable the ship. Ford hits his head in his cell-like bubble and is knocked out. Dipper uses the pulse option on the gun to disable the ship, which sends it crashing down in the woods.

After recovering, Dipper opens the pod and frantically tries to revive Ford. The malfunctioning prison droid that had captured Ford returns to take Ford and Dipper away. Dipper stands up to the droid, yelling that he isn't scared and that nothing will take away his uncle. The droid does not detect any fear and disables itself. Ford finally recovers and praises Dipper.

Back at the Shack, Mabel is sad that summer is almost over and that high school is awful. Stan comes in to cheer her up, reminding her that growing old doesn't mean you have to grow up and that it's okay to have fun even as an adult. Mabel says that she doesn't want to say goodbye to Gravity Falls, but Stan reminds her that she still has her brother, no matter what. Mabel is cheered up by this. However, her walkie-talkie starts to crackle, broadcasting a conversation between Dipper and Ford.

Ford again extends the opportunity to stay in Gravity Falls to Dipper. Dipper decides to take the offer, and they return to the Shack. Dipper bursts into the attic, eager to share the news with Mabel, but Mabel already knows, having heard it on the walkie-talkie. Mabel is despondent, explaining that she had a horrible day and that when summer is over, the only thing she won't have to leave behind is her brother. However, if Dipper stays, she would have to leave absolutely everything behind. Dipper reminds her that things change, and summers end. She grabs a bag and runs away crying into the woods.

After sitting down against a tree, Mabel looks through the bag, only to find that she had grabbed Dipper's bag by mistake. She wishes for summer to last forever. Blendin Blandin appears, offering to help her make a "time bubble" that will make time stop, letting summer last as long as Mabel wants it to. All he needs is a "gizmo" from her uncle - the rift. She finds it in Dipper's bag, not knowing of its importance.

In the basement, Dipper wonders if he's making the right decision by staying. Ford reminds him that they need to save the world and asks for the rift. He reaches into his bag, only to pull out a birthday party invitation instead. He realizes that he has Mabel's bag - but it's too late.

Mabel hands the rift over to Blendin, who takes it and smashes it on the ground, stomping it with his boot. The liquid of the rift surges across the ground as Blendin begins to cackle, taking off his goggles and revealing his eyes to be the same as Bill's. Bill, in Blendin's body, snaps his fingers, knocking Mabel unconscious and causing an unearthly wind to howl. Bill leaves Blendin's body and enters the physical world, screaming about how the gateway between the Nightmare Realm and the real world has been opened after being prophesied for a billion years. Bill rises to the sky as a giant cross appears thanks to the rift's influence - a gateway from the Nightmare Realm to Gravity Falls. Dipper and Ford run outside to investigate the chaos, seeing the gateway and a humongous Bill. Ford realizes that they've failed and that Weirdmageddon has begun.

Episode 2: Weirdmaggedon
Bill Cipher laughing at the gateway between the Nightmare Realm and Gravity Falls, Oregon. His body gains flesh, metal, and pure energy as Bill finally obtains a physical form, becoming a triangle of light. Blendin Blandin sees the chaos above, and is helpless to watch as Mabel's unconscious body is lifted up and sealed in a pink bubble emblazoned with a shooting star. Chains wrap around the bubble, trapping Mabel inside. Blendin taps his wristwatch, informing the Time Paradox Avoidance Enforcement Squadron of the situation before he teleports away.

The townspeople of Gravity Falls all look up to the sky in fear as Bill grows in size, becoming a rotating pyramid-like abomination with six arms and a pure black form with multicolored energy. Bill returns to his normal form and floats down to the town, announcing that he will be the lord and master of Gravity Falls for eternity. He then melts a statue of Nathaniel Northwest as the townspeople watch in despair. Bill then introduces the town to the other residents of the Nightmare Realm that Bill calls his friends, each more grotesque and anomalous than the last; 8 Ball, Kryptos, Xanthar, Teeth, Keyhole, Hectorgon, Amorphous Shape, Pyronica, Paci-Fire, and a large army of Eye-Bats Bill calls "these guys." The townspeople don't react kindly to the display, urging Bill and his friends to get out of town. Preston Northwest offers to join Bill and become one of his "horsemen of the apocalypse," but Bill switches all the orifices on Preston's face instead, laughing as the crowd runs away in horror. Bill promptly unleashes the winged eyeballs and madness bubbles all over town. The eyeballs petrify and abduct the townspeople, and the bubbles instill madness in everything they touch. Bill also summons a gargantuan black pyramid from the ground to serve as his castle and animates the Gravity Falls water tower. After proclaiming that time is dead and meaning has no meaning, Bill welcomes everyone to Weirdmageddon.

Meanwhile, Dipper and Ford watch the madness from the Mystery Shack. A massive group of animals, including the gnomes and a Manotaur, stampede out of the forests and away from Bill, knocking Dipper over. Ford picks Dipper back up, telling him that with every passing minute, Bill's dimension leaks into theirs and his power grows. Dipper thinks that the interdimensional rift must have cracked in his backpack when Mabel carried it, putting her in danger. He runs off to go find her, trying to contact her through their walkie-talkies. Ford stops Dipper and tells him that before they can find Mabel, they must defeat Bill. Their best shot is to knock him back into the rift from where he came before Weirdmageddon spreads across the entire world. Ford isn't sure it's possible, but says he has to try. Dipper and Ford abruptly stop when a gnome announces that a "weirdness wave" is headed their way. They rush inside the Shack as a giant pink tsunami washes over the entire town. The weirdness wave spawns a tentacle in Soos' backyard, makes his grill turn into a monster, and it turns Abuelita into a chair. Soos is shocked, but Abuelita tells Soos to go help the others around town. Soos follows her order and heads off. At the Shack, Stan is telling off Gompers for chewing on his fez's tassel. The weirdness wave causes Gompers to grow to an immense size, and Stan runs away with Gompers in pursuit. Next, the wave washes over the arcade, bringing Rumble McSkirmish and other arcade characters to life.

Meanwhile, in the Gravity Falls Maximum Security Prison, Lil' Gideon and the other inmates have made finger-paintings to share with each other. After the counselor in charge of the event accuses Gideon's Mabel-centric art of being abnormal, the other inmates rally to Gideon's cause and back him up. They chant Gideon's name until Gompers chews through the prison walls, creating an escape route. After seeing the mayhem and madness going on across town, Gideon comments on how "Bill came through." Bill and his friends gather around the center of town, ready to cause more havoc. Dipper and Ford have followed them, hiding at the top of the Gravity Falls church. Ford has brought a black suitcase labelled "EXPERIMENT 618" with him. Inside is a quantum destabilizer, a powerful gun that will have the ability to knock Bill back through the rift and shut down Weirdmageddon - that is, if he can aim the gun correctly. With the gun only armed for one attack, Ford locks Bill in his sights. However, the weirdness wave causes the bell in the church to personify, ringing of its own accord and causing Ford to miss the shot. It fires through Bill's top hat, sailing into a tree. Bill instantly repairs the damage done to his hat and spots Dipper and Ford, firing a laser right through the church tower that obliterates it instantly. The two survive, but are badly injured. Ford, pinned under rubble, tosses Dipper a bag with the three journals inside. Ford begins to tell Dipper that there's another way to defeat Bill, but he is cut short when Bill appears, towering over Ford. Dipper manages to hide before Bill can spot him.

Bill captures Ford and presents him to his friends, telling them that Weirdmageddon wouldn't be possible without Ford. Bill makes an offer with Ford and tells him it's not too late to join Bill's side. Ford refuses, saying he'd rather die, so Bill turns him into a golden statue to use as a back-scratcher. Dipper, who has gotten back to street-level, yells that he's had enough. Bill flies over to Dipper, asking him what he could possibly do to defeat Bill in one shot. Dipper flips through Journal 3, trying to find Bill's weakness. With no answers, Dipper panics, and leaps towards Bill, trying to punch him. In response, Bill knocks Dipper backwards, causing him to fly into a tree. Bill then telekinetically seizes the three journals, burning them in front of Dipper. After Bill shows Dipper the statue of Ford, saying that this is what happens to heroes in his world, Bill tells 8-Ball and Teeth that they can eat Dipper for a snack. Bill then converts a random car into a sleek getaway ride for himself and his other friends. The car flies away to the Fearamid leaving Dipper, 8-Ball, and Teeth behind. The two beasts chase Dipper into the forest as what's left of the journals blows away in the wind.

Three days into Weirdmageddon, Gravity Falls has become a complete wasteland. Shandra Jimenez reports the weather as the winged eyeballs petrify more and more townspeople. Dipper evades the eyeballs, calling Mabel via walkie-talkie. He talks to her about how he hasn't found her or Stan and isn't even sure she can hear him. Dipper decides to go to the mall, wondering if there are other survivors there. On the way, he runs into The Horrifying Sweaty One-Armed Monstrosity, who wants Dipper to "get into his mouth." As Dipper tries to open the mall's locked doors and the Monstrosity gains on him, its hand pushes Dipper through the doors.

As Dipper wanders around the mall looking for his family, he finds a tray of nachos in the food court. As he moves to pick them up, he triggers a trap and is caught in a net. Wendy reveals herself from inside a potted plant to examine her trap, but is surprised to see Dipper. She frees him from the net and tells Dipper how she's been trained yearly at Christmastime to handle apocalyptic scenarios such as this. Dipper and Wendy hug, happy they have each other. Wendy also reveals she ran into Toby Determined earlier, who joins their group. They then escape to Wendy's secret hideout. Wendy tells Dipper that Robbie, Lee, Nate, Tambry, and Thompson were all petrified before she found Dipper. Dipper explains Ford's apprenticeship offer and his fight with Mabel to Wendy, who then invites him onto the rooftop of their hideout. As they survey the weirdness around them, Dipper mournfully tells Wendy they lost the battle against Bill. Wendy gives him a pep talk, saying it's not over yet and that he needs to get Mabel back if he wants to defeat Bill. She tells Dipper that when he and Mabel are together, there's nothing they can't do. Dipper realizes she's right, but he still doesn't know where Mabel's bubble is. Suddenly, a billboard blocking the view is eaten by a monster, which reveals Mabel's location: right near the Floating Cliffs. Wendy comes up with a plan to get to Mabel's bubble.

Meanwhile, Bill and his friends are having a rave party inside the Fearamid. They're playing party games with the statues of the Gravity Falls citizens. Bill tells his friends that once the party is over, he'll unveil Phase 2 of Weirdmageddon. Suddenly, the Time Police, Blendin, and Time Baby barge in, crashing the party. Lolph and Dundgren, Blendin, and Time Baby accuse Bill of possessing Blendin and almost destroying reality. Bill vaporizes the Time Police and Time Baby instantly, and the party resumes. Blendin escapes unharmed and teleports away. 8-Ball and Teeth approach Bill, worried that Dipper might foil their plans. Bill says he's not worried, and that he has "someone on the case." Dipper and Wendy break into the abandoned auto mart, planning to hotwire a car and use it to get to Mabel. Toby tries to steal an air freshener, but is knocked unconscious by tranquilizer darts. Dipper and Wendy are accosted by the Discount Auto Mart Warriors, a group of escaped inmates led by Gideon himself. Dipper tries to explain that they just want one car, but Gideon interrupts, telling them that Bill himself has ordered Dipper and Wendy to be put under arrest.

Gideon explains that Bill has appointed him as the master of the wastelands so that he could watch over Mabel's bubble. He also shows that he has a key that can unlock her bubble. Gideon is ecstatic over his new job, and he still believes that Mabel is destined to be his. Gideon then tells Ghost-Eyes to bring Dipper and Wendy to Bill. Before he does so, Wendy attacks Ghost-Eyes and steals the key from Gideon. She then dropkicks Gideon into a crowd of Warriors and drives off with Dipper. The Warriors take Gideon and start following them. Wendy tells Dipper that she doesn't have a license while she swerves around the Monstrosity. Gideon's henchmen aren't so lucky, and the Monstrosity manages to eat a car. Ghost-Eyes and Gideon escape as Ghost-Eyes questions why Gideon is keeping Mabel in her bubble. Dipper and Wendy notice a group of weirdness bubbles up ahead, which they have no choice but to drive through. Their animation styles change drastically in each bubble they go through, ranging to becoming birds to anime to live-action. Gideon and his henchmen travel through the bubbles as well, still in pursuit.

Eventually, the two parties are neck-and-neck. Gideon begins to crash his car into Dipper and Wendy's. Dipper realizes that they are close to Mabel's bubble, but have to make a gigantic jump across a canyon. Wendy manages to avoid Gideon's attack and drive the car across the canyon. However, the car crashes and rolls across the ground, heavily injuring Dipper and Wendy. Dipper crawls out of the car but bumps into a mysterious hooded figure that reveals themselves to be Soos. Soos tells Dipper and Wendy how he's been wandering across the plains and helping strangers in need. He also reveals that Gideon and his henchmen have surrounded Dipper and Wendy. Gideon then summons an army of Bill's Eye-Bats to retrieve Dipper and his friends, proclaiming that Mabel is his. Dipper then tells Gideon that Mabel doesn't love him, and never did. He continues to say that Gideon can't force Mabel to love him, but he can try to become someone worthy of loving.

He tells Gideon that if he stands up to Bill and lets Dipper free Mabel, that would make him a better person and would make him better in Mabel's eyes. Gideon decides to help Dipper but says that he has to tell Mabel that Gideon helped set her free. Dipper accepts, and Gideon and his henchmen drive away to fight Bill's Eye-Bat army. Dipper, Wendy, and Soos make it to Mabel's bubble and unlock it with the key. Dipper warns his friends that they have no way of knowing what dangers Bill has put inside, but they know they have to do it for Mabel. They walk inside the unlocked bubble as the foreground fades to white.

Episode 3: Weirdmaggedon 2: Escape from Reality
Manly Dan is turned to stone, and Sprott is seen holding a triangular sign. He is convinced that if he accepts Bill Cipher's ways of life, he and others will be spared. However, he too is turned to stone and brought to Bill's pyramid fortress, the Fearamid.

Bill clinks a golden Ford and announces the latest successes, which include turning citizens of the barren wasteland once known as Gravity Falls, Oregon into stone to be used as a throne for Bill. Suddenly, Lazy Susan is the one exception seen coming to, and then later going back into unconsciousness. He announces his plan to take Weirdmageddon worldwide, and the demons make their way toward the edge of Gravity Falls. But instead of escaping to the rest of the world, they hit a shield and ricochet back toward Bill's fortress. Bill is angry about the failure, and told his injured friends to "walk it off!"

Dipper, Wendy, and Soos enter Mabel's Prison Bubble. After taking a few steps, the floor begins to shatter and Soos grabs Dipper and Wendy, expecting a hard fall and exposing his wish to die hugging. Instead they land on a bounce house, surprised that this is Mabel's prison. Composed of animated plush animals and many of Mabel's idols and imaginary beings, such as Duck-tective, Aoshima, a gigantic Waddles (who serves as the world's transportation) and Xyler and Craz whom appear to offer to take the mesmerized group on a grand tour, an offer which cannot be rejected, literally.

On the tour, Xyler and Craz introduces the group to Mabeland, "better than perfection", and with no rules, except one, which the two withhold, since they believed no one would ever want to break it. They arrive at a beach, crowded with more of Mabel's fantasy creatures. Penguins arrive with bowls of punch, which Soos nearly consumes before Dipper slaps it out of his hand, reminding them that this world was created by Mabel's delusions and brought to life with Bill's dark powers, advising them not to get comfortable in Mabeland. Asking where Mabel is, Xyler and Craz reveals she was in the tallest tower in Mabeland, guarded by two muscular waffles with knives for spears.

The group storms the tower, with Soos taking a bite out of the guards and Wendy defeating the other before breaking down the door. The group urges some partying animals to flee, then rush up the tower into a dark room. Mabel, lying asleep on a bed, is picked up by Soos, waking shortly after, while Wendy and Dipper barricades the doors, preventing more guards from entering. Mabel, unable to get the group's attention, uses her powers to suspend everything in the room, arranging them so that the group is seated and the guards peaceful.

Mabel happily reveals that she awoke in this world, and is the ruler of it all as the mayor. Still harboring grief over being forced to grow up and leave Gravity Falls, possibly without her brother, she is overjoyed to remain in her world of fantasy, now complete with the group by her side. Dipper naturally highlights the irrationality of her actions, only to be introduced to Dippy Fresh: a replacement for Dipper in this world. Mabel is naturally more attracted to Dippy Fresh, due to his unwavering support for her, and Soos readily accepts Dippy's love of "punctuating all my sentences with a high five." Mabel assures them that they will enjoy themselves here, with everything provided to them even when they didn't know they wanted it, but Dipper tries to convince Mabel to leave.

he restores the group and conjures a hamburger with pudding filling, one which Soos takes a bite out of and likes.

Wendy begins to side with Dipper, taking into mind the dire state of Gravity Falls, but is interrupted by her friends, who plan to ride a monster truck filled with explosives to a high school, destroy it, and stick a plunger on the principal's head, a event that Wendy has always wanted to participate in, causing her to leave with her friends. Soos assures Dipper that he remains committed to the mission, but his resolve is broken when he is heartwarmingly reunited with his father: conjured from his own imagination as he is unable to remember how his father looked like. Dipper begs him not to give in, but fails. Dipper asks Mabel to stop them and return back to reality, asking her if fulfilling their desires is really such a great idea. However, she argues that this way everyone is happy, and urges Dipper to just embrace the pleasures of this new world, and is about to show him his desire when he rejects it and quickly leaves, to her disappointment.

In the Fearamid, Bill is angered and unable to understand why they aren't able to extend their reach and leave Gravity Falls to dominate the world. He realizes that Ford is the only one able to understand the shield and contemplates his next move. He is interrupted by Keyhole, who informs him Gideon failed to stop Dipper, allowing him and his group to enter Mabel's bubble. Bill is not worried by this, calling Mabel's bubble one of his most diabolical traps yet, one that would require "a will of titanium" to resist it's temptations and escape. He asks for Gideon and tells Keyhole to "take the day off, as things got much more interesting."

Dipper is found at Giggle Creek, who is beginning to accept that Mabeland truly is perfect compared to the real world, one example being how his thrown stones skip perfectly in the creek. His thoughts are voiced aloud and thus heard by Wendy, who comments on his weird behavior. She voices out her growing dislike for Mabeland, and subsequently praises Dipper for being so smart, saying that if he was older, she would be his girlfriend. While Dipper is shocked by this, she realizes that they could ask Mabel to make Dipper older so they could become an item and live together in Mabeland forever, and asks Dipper to agree and come with her by taking her hand. Dipper nearly accepts but realizes that Wendy would never say such things: she is only saying what he wants her to say. He is thus able to realize this Wendy is a temptation and only a fantasy and backs away from her.

"Wendy", having been rejected by Dipper, reveals to be nothing but insects, before breaking apart and with the cockroaches crawling away. The world suddenly darkens, and a "stuffed animal tree", now revealed to be corrupted with glowing eyes, chides Dipper on his decision, with the animals warning Dipper he was always being watched. Dipper is terrified by them, but is distracted by the boy band Several Timez on a bicycle. When he turns back to the tree, it has returned to its original adorable state. Realizing how horrifying this world truly is, he announces that he had to return to reality.

This causes him to break Mabeland's one rule: To never mention reality. He is suppressed by some waffle guards, who prepare to exile him back to reality forever. Dipper begs to Mabel who arrives at the scene not to allow them to do so, and she commands them to stop. The guards decide that Dipper must plead his case of "Fantasy vs Reality" in court.

All of Mabeland's creatures, including the real Wendy and Soos, arrive to see the trial. The judge is temporarily distracted by a piece of rope, but quickly starts the case by listing the conditions: If Dipper wins the trial, Mabel will come with him back to reality. However, if Mabel (represented by Xyler and Craz) wins, she will stay in Mabeland, and Dipper would be banished and replaced by Dippy Fresh, who has become a town favorite. The outcome of the trial would be decided by the jury, made entirely out of clones of Mabel, just in different sweaters, who are mesmerized by Xyler and Craz. They are to begin their opening statement, and their insults to reality cause Dipper to object, however, he is quickly overruled. They bring out Mabel's scrapbook, as evidence to how horrible reality can be, and begin showcasing Mabel's memories in virtual reality in the courtroom.

The first memory: October 10, the twins second grade photo day. Mabel had done up a new hairstyle for Photo Day, and had intended for it to be the best photo day ever. However, the hairstyle was ruined when a girl stuck a piece of gum in her hair, making her distraught. Her brother, initially at a loss for words, was unable to help and this caused her to run away in tears. Xyler and Craz used this incident to justify how cruel reality was, and when Dipper argues it was just one bad day, they bring up another memory, targeted at him.

This memory was of the twins in fourth grade, on Valentine's Day. Mabel had received lots of cards, while Dipper had none, causing his classmates to mock him and for him to leave in embarrassment. One classmate remarks to Mabel that he was surprised Dipper was actually Mabel's brother.

Dipper argues that these all occurred in the past, but Xyler and Craz counter by arguing that Dipper had also been subject to harsh reality over the course of the summer by being rejected by Wendy, failing to stop Bill from entering into their real world and arguing with Mabel. They conclude that one should simply save themselves from that pain and instead stay here in Mabeland, where all their desires will be fulfilled, and create pug-shaped sundaes for the jury.

Judge Kitty Kitty Meow Meow Face-Shwartstein is convinced by their argument, and is about to declare Mabel the winner when Dipper interjects, claiming he had not even had a chance to give his case. The judge is skeptical, but when Dipper calls Mabel, confident of winning, to the witness stand, he overrides Mabel's objections, as he was curious to see what he had to say.

Dipper begins by acknowledging he could never be as amazing as all the fantasies that Mabel had made for herself, but argues that even with all her desires fulfilled here in Mabeland, she still didn't want to stay. Mabel refuses to listen, and tries to block him out, but he presses further, claiming that it was because Mabel didn't want to grow up and have to face the horrors of high school, and life without her brother, and have to abandon Gravity Falls, ultimately leaving her childhood behind, that made her choose to stay in her delusions. Mabel attempts to deny it, but Dipper reaches out to her, asking that instead of hiding from the bad events in life, she should go through them together with the people that care for her: her family and friends.

He then uses the scrapbook to show how they had overcome both incidents together. For the Photo Day incident, Dipper had shaved the center of his head, and while this made him look ridiculous, it convinced Mabel to follow suit, causing them both to have a good laugh out of it and have their photos taken. For the Valentine's Day incident, Mabel had used all her cards to form a huge card for Dipper, cheering him up. Dipper tells Mabel that as long as they face life together, just like they had over the course of the summer, and beat Bill together, they could accomplish anything, and this was what made reality so much better. He admits it was foolish of him to betray Mabel to become Ford's apprentice and miss out on growing up with Mabel. He assures her that he would reject the apprenticeship so that he could stay with Mabel after the summer. He asks her to return with him, and Mabel, convinced by the sincerity of her brother, embraces him in an awkward sibling hug, now a sincere sibling hug, against the audience's warnings.

This causes Mabel's reign and control over Mabeland to be undone, and all the creatures, except Xyler and Craz, to reveal their true corrupted selves. Mabel, realizing how much she disliked the place even before the creatures revealed themselves, is terrified, and she together with Dipper, Wendy and Soos, flee the courtroom as Mabeland falls apart. They mount Waddles and raced away from the now nightmarish land. Grabbing a needle from a giant ball of yarn, Mabel rushes towards the edge of the prison bubble and destroys her world of illusions, popping the bubble and releasing the group from her prison.

Mabel tells Dipper that while she was touched by his argument, he didn't need to give up the apprenticeship for her, but Dipper is decided and keeps his word, promising to stay with Mabel after the end of summer. She is surprised that reality seemed just as horrible under Bill's reign as her nightmarish prison, but Dipper assures her that now that they were together, they would restore Gravity Falls and defeat Bill.

They find the town of Gravity Falls deserted, and decide to take shelter in the Mystery Shack. Hearing noises inside, they arm up and break down the door screaming. What they find are refugees, including Stan and other townsfolk and mysterious creatures of Gravity Falls, who scream back at them. Both groups are surprised to find each other alive. Just before the episode ends, Multi-Bear appears from the toilet, informing them they were out of toilet paper. Seeing both groups in shock, he asked if he had missed out on anything.

Episode 4: Weirdmaggedon 3: Take Back the Falls
Dipper, Mabel, Wendy, and Soos barge into the Mystery Shack to be greeted by the remaining refugees of Gravity Falls, including Stan, Old Man McGucket, Pacifica Northwest, and other townsfolk and mysterious creatures of the town. Dipper and Mabel are happy to see Stan, and they hug him with Soos and Wendy. The twins question why everyone is hiding out in the Shack, but before they can get an answer, an Eye-Bat sweeps the outside of the Shack, forcing everyone to hide.

Once the coast is clear, Stan shows Dipper and Mabel life in the Shack. The situation seems rather grim for the survivors; many of them are injured and food is becoming scarce. Stan shares his story to the twins. He was working outside when Weirdmageddon struck, and sought refuge in the Shack. He learned that the unicorn hair barrier that Dipper and Ford set up around the Shack protected it from weirdness waves and all things related to Weirdmageddon. When McGucket showed up near the Shack with the refugees, Stan elected himself chief of Gravity Falls due to Tyler Cutebiker's absence and let them stay. His current plan is to hide out in the Shack until they run out of food, with eating the gnomes as a backup plan.

Dipper angrily informs Stan that Ford has been captured by Bill and that they cannot just stay cooped up in the Shack. Stan grudgingly shrugs the issue off, believing that Ford has to get himself out of the mess he made. Stan insists everyone will be fine in the Shack, and thinks that the rest of the townspeople will be fine on their own. However, a news broadcast from Shandra Jimenez inside the Fearamid shows the throne made out of petrified townspeople to the survivors for the first time. The refugees are shocked to see their loved ones turned to stone.

While the refugees are discouraged, Mabel and Dipper try and inspire them to fight back to save their friends, saying that Bill wants them to run and hide. Dipper says that Ford knows Bill’s secret weakness. If all of the refugees band together, they can rescue Ford, find Bill’s weakness, and save the town. The refugees are optimistic, but Stan objects on the grounds that the Shack is the only place safe from Bill and that there's no way to bring it to him. This gives McGucket an idea, but he says it will require everyone to work together. He puts on his goggles and begins to share a plan while Stan looks on uncomfortably.

Inside the Fearamid, Ford is reverted from his gold state inside a private study and chained to the floor. Bill Cipher rises up from the ground playing a piano. He explains Ford is trapped inside a penthouse suite in the tip of the Fearamid. Ford deduces that Bill wants something from him. Bill explains that with his newfound powers, he can control all of space, matter, and time. He reveals that he used to live in the second dimension until he destroyed it, and is aiming to do the same to this one. The only problem is that he, along with the rest of his friends, can’t escape Gravity Falls. Ford thinks that this is due to a natural magnetism attracting weirdness to Gravity Falls, the event he’s studied for years, a force so strong that it forms a barrier that prevents that weirdness from going outside the town. He says there’s a way to break this barrier, but he’d never tell Bill. Bill tries to persuade Ford by telling offering him unlimited power in a world without restrictions or laws. Ford again refuses, calling Bill insane. Bill decides to find the equation needed to break the barrier in Ford’s mind. However, Ford reminds Bill he can’t unless he makes a deal with him. Bill decides to try and find Ford’s weakness and force him to make the deal, chaining him up further.

Back in the Shack, McGucket reveals the blueprints for his newest robotic invention. While the twins and the other survivors are impressed, Stan remains pessimistic. In spite of the odds, all of the refugees band together to assemble McGucket's giant mech using various materials found inside the Shack and elsewhere in the surrounding area.

Having made a flag for their resistance, the refugees sit outside around a bonfire. Mabel has knit special apocalypse sweaters for everyone, including a llama sweater for Pacifica which she begrudgingly wears. Mabel thinks that they might have a shot at defeating Bill. Dipper laments that the only birthday present he wants is to survive the summer. Soos assures Dipper that if they live, the entire town will throw Dipper and Mabel a birthday party. Dipper cheers up and wonders where Stan is. Stan is away from the crowd, ranting to Shmebulock about how the resistance’s plan is garbage and how no one’s listening to him. When Dipper and Mabel ask Stan what’s wrong, he shares his feelings about the plan. He doesn’t want to save Ford, as he’s still upset that Ford never thanked him for rescuing him. Stan doesn’t understand how Ford is the one who brought Weirdmageddon to being in the first place, but he’s still called the hero. Dipper says that Ford is a hero because he didn’t want to hide, but Stan retorts that if Ford hid, he would still be alive. Mabel breaks up the conflict, assuring everyone their plan will work.

The next day, everyone gathers inside the Shack with McGucket hoping his invention works. Dipper pulls a lever inside the Shack, causing mechanisms to activate that turn the entire Mystery Shack into a gigantic mech. The mech walks past some other survivors on its way to the Fearamid, where it’s shown that in the throne room, Bill and his friends are torturing Ford by blasting him with lasers. Ford is in pain, but doesn’t give in. Before Bill can start torturing Ford again, a dinosaur head busts through the wall of the Fearamid, outraging Bill. Soos steps out onto a platform on the mech, dubbing it the Shack-tron. Bill finds it adorable the refugees are fighting back, and orders his henchmen to fight them. They increase their size and jump out of the Fearamid, ready to fight. Stan thinks the plan was a bad idea.

Soos tells the henchmen to hand over Ford, or else they’ll fight. The henchmen immediately rush the Shack-tron to battle. Inside the Shack-tron, the refugees control various mechanisms that control different parts of the actual mech, using weapons to fight against the henchmen. Rumble McSkirmish and Wendy attack outside the Shack-tron, with Rumble attacking from afar and Wendy piloting a rogue Eyebat to turn the henchmen to stone. Stan desperately tries to find an exit. Xanthar rushes the Shack-tron, pushing it through several stone walls. Using all of their power, the refugees control the Shack-tron to throw Xanthar into the distant mountains, subduing the henchmen.

Bill is upset as Ford congratulates Dipper and Mabel for their efforts. Bill realizes Ford cares about the twins, and wonders if torturing them will be more effective than torturing Ford. Ford is turned back into a gold statue as Bill flies over to the Shack-tron and attempts to crush it with a giant fist. However, it remains intact thanks to the unicorn barrier. Bill becomes enraged and repeatedly punches the Shack-tron. The refugees use the dinosaur arm to tear out Bill’s eye and distract him. Realizing now is their chance to rescue Ford, a team composed of the twins, Stan, Soos, McGucket, Wendy, Pacifica, and Sheriff Blubs, is ejected out of the Shack-tron, using parachutes to land inside the Fearamid.

Everyone lands right next to the human throne. Mabel travels up the human throne using her grappling hook and finds Ford as a gold statue. Stan yells at her to take Ford and leave, but Dipper says they don’t know how to unfreeze him. Gideon Gleeful, trapped in a cage hanging from the ceiling, says he knows how to unfreeze everyone. He’s dressed up in a sailor costume and explains that Bill forced him to dance for all of eternity as punishment for betraying him. Gideon says that Tyler Cutebiker is the load-bearing statue in the human throne, and if he’s pulled out, the throne will fall apart. When Dipper does so, the throne breaks up and everyone is turned back to normal. In the chaos, Gideon’s cage is knocked to the ground and he’s freed.

Wendy and Pacifica reunite with their families, and Blubs meets up with Deputy Durland. All the citizens are happy to be freed, and Ford is un-petrified as well. He meets McGucket for the first time since he left Ford. McGucket decides to forgive Ford, hugging it out. Stan gruffly greets Ford as well. Dipper and Mabel ask Ford what Bill’s weakness is. He puts on some gloves and asks for something to write with. The only he thing he gets is a blue spray can, but decides it will do. He begins spray-painting a circle on the floor and ends up creating the Bill Cipher Wheel, complete with its ten symbols.

Ford explains that the Wheel is a prophecy. He found a drawing of the Wheel on the wall of a cave many years ago. He recognized some of the symbols then, and recognizes all of them now. It was prophesied that the symbols would create a force that could defeat Bill and reverse his weirdness. Ford dismissed it as superstition at first, but realizes now it’s destiny. Ford tells Dipper to go to the pine tree and Mabel to go to the shooting star. Soos steps onto the question mark and Robbie walks onto the heart. Gideon goes to the pentagram, the sign for the Tent of Telepathy.

Meanwhile, Bill is still fighting the Shack-tron. It manages to pin Bill to the ground, but Bill realizes its legs aren't inside the unicorn barrier. Bill utilizes this weak spot to flip the Shack-tron over, tear off a leg, and smash it into the Shack-tron, sending it flying. Back on the Fearamid, Ford tells everyone in the Wheel to hold hands. When Dipper wonders who the bag of ice represents, Ford explains that some of the symbols are metaphors. The ice is someone cool in the face of danger, causing Wendy to walk onto the symbol after encouragement from her friends. When Ford says the spectacles are someone scholarly, McGucket steps forward. Pacifica walks onto the llama, as her sweater matches it. Ford himself goes to the six-fingered hand. Everyone holds hands, creating a ring of energy that surrounds the Wheel and envelops the Fearamid with dark clouds. All the other citizens rush out of the room.

Ford realizes there’s only one person left to join the Wheel: Stan. Ford yells at Stan to join the wheel, but he remains skeptical. Everyone gets upset at Stan, telling him to join. Stan tells everyone that he isn’t the enemy, and that Ford is for bringing Bill into Gravity Falls. Ford pleads to Stan one more time. Stan finally agrees, but only if Ford thanks him for spending 30 years bringing him back into this dimension. Ford thanks Stan, getting him to join the Wheel. However, after Ford corrects Stan on his grammar, Stan pushes Ford, breaking the link. The two begin to fight as Mabel and Dipper try to stop them. While they’re distracted, Bill looms above them, having beaten the Shack-tron and regenerated his eye.

Part 2 - Weirdmageddon 4: Somewhere in the Woods
Bill laughs at the resistance, happy that everyone who could pose a threat to him is in one spot. He sends a wave of fire at them, burning the Wheel away. He also traps Stan and Ford, binding them with ropes. The resistance prepares to fight against Bill, saying they aren’t afraid of him. Saying they should be, Bill snaps his fingers and turns everyone but the Pines into posters showing their screaming faces. Bill then imprisons Dipper and Mabel in a triangular cell. Bill says he’ll spare the twins if Ford lets him into his mind, giving him one last opportunity. The twins yell at Ford not to do it, causing Bill to angrily fly up to them. Mabel quickly takes out her spray can and sprays Bill’s eye, distracting him again and freeing Stan and Ford.

While Bill’s distracted, Dipper takes out his size-altering flashlight and enlarges the cell, making it so him and Mabel can walk through. Dipper yells at Stan and Ford to run, saying him and Mabel will take care of Bill. When Ford expresses disbelief, Dipper says to trust him. Him and Mabel goad Bill into chasing them down a long hallway. As Bill moves to follow them, Stan and Ford try to escape. However, Bill places them inside a larger cell like the one he put the twins in. Bill then changes into a monstrous red and yellow form and chases the kids throughout the Fearamid, threatening to disassemble their molecules. Mabel and Dipper use their grappling hook to escape up a chute, with Bill close behind.

Stan feels guilty for the current situation, feeling he should’ve shook Ford’s hand and that he really is a screw-up. Ford tells Stan not be to so hard on himself, as he made the deal with Bill in the first place. He laments Stan and his’ relationship, wondering how Dipper and Mabel get along so well. Stan says they’re kids, so they’re still innocent. Ford decides to let Bill enter his mind, as even if the galaxy is destroyed, there’s a chance Bill will let Dipper and Mabel live. Ford says that if there wasn’t a metal plate in his head, Stan could erase Ford’s mind, killing Bill. Stan wonders what would happen if Bill went in his mind, but Ford says there’s nothing Bill wants in there. Ford remains adamant in his decision, as it’s all they have left.

Meanwhile, Dipper and Mabel run into a dead end. Mabel uses the size-altering flashlight to enlarge her hand, punching a hole through the wall and into the outside. Dipper moves to round up the refugees, but sees that Bill’s henchmen have done that first. While Dipper and Mabel watch, Bill sneaks up behind them and brings them back to Stan and Ford. Bill tells Ford his time’s up, preparing to kill one of the twins. Before Bill does so, Ford surrenders as Stan objects. Bill removes the cell and ties up Stan. Ford’s only condition to the deal is that Bill lets Dipper and Mabel go. Bill accepts as he shakes hands with Ford. Bill’s physical form turns to stone as his mental form goes inside Ford’s mind.

Ford’s mind is a bleak white landscape with a single wooden door. When Bill opens it, he’s greeted with Stan playing paddleball inside the Mystery Shack. Stan reveals he and Ford swapped clothes and pretended to be each other so that Bill would enter the wrong mind. In the real world, Ford takes off Stan’s fez and takes out the memory erasing gun, setting it to completely erase Stan’s memory. In the mindscape, Bill tries to call the deal off as the door shuts and the room becomes enveloped in blue fire. Stan explains his mind’s going to be erased with Bill in it. Bill tries to escape and resorts to bargaining with Stan, but Stan doesn’t budge. Bill’s form heavily glitches out as he speaks backwards messages. Stan punches the weakened Bill into nonexistence as his mindscape becomes consumed by fire, happy he was good for something after all.

In the real world, Ford finishes erasing Stan’s memory. Everyone is freed from the tapestries. Outside the Fearamid, Bill’s henchmen are sucked back into the portal, with the bricks of the Fearamid not far behind. The portal itself closes and explodes into a great shockwave, returning the entirety of Gravity Falls back to its own version of normal. The only thing that remains of Weirdmageddon is Bill’s petrified physical form. Stan regains consciousness in the forest as Dipper, Mabel, and Ford run to him. Unfortunately, Stan doesn’t remember who any of them are. As Mabel desparately attempts to jog Stan’s memory, Ford sadly explains that Stan sacrificed his memories to save everyone, and that he's their hero. Dipper and Mabel cry as Ford consoles Stan. The four begin to walk towards the now-ruined Mystery Shack. Dipper and Mabel try to remind Stan of the Mystery Shack and themselves, but Stan still doesn’t remember anyone. Dipper wonders if saving the world was worth it if Stan doesn’t remember his friends and family. Mabel tries to find something to bring Stan’s memory back and eventually stumbles across her scrapbook.

Mabel sits down with Stan and begins sharing the stories and memories of her time at Gravity Falls with him. Dipper and Mabel try to frantically remind Stan of the summer, but Stan can’t remember it. As Waddles jumps onto Stan’s lap, Stan involuntarily calls Waddles by his real name, even though he shouldn’t remember it. Ford realizes the scrapbook is working as Stan also calls Soos by his name. Dipper and Mabel continue to show Stan more activities in the summer, showing him all of the things Stan did with them. Everyone begins to laugh, and even Stan joins in as he puts his arms around the twins.

Life in Gravity Falls is back to normal. Shandra shares a news report, expressing happiness that Gravity Falls is back to normal after the events of Weirdmageddon. Some lingering Eye-Bats remain on Sprott’s farm, and zombies pop up in the cemetery as the Valentinos bury them back in their graves. Mayor Tyler gives a speech to the townsfolk to announce the “Never Mind All That” Act, created in response to Weirdmageddon. The act proposes that if anyone asks what happened to Gravity Falls in the past few days, the people must respond with “never mind all that” or risk being tased. Sheriff Blubs and Deputy Durland go mad with power and, it seems, love.

Shandra also reports that the Northwest family has gone broke. After Preston Northwest pledged allegiance to Bill and put his money in “weirdness bonds,” he had to sell the family mansion to preserve his family’s fortune. On the bright side, McGucket regained all of his memory and has made millions of dollars patenting his inventions. He decides to buy Northwest Manor with his newfound money. In addition, Stan has fully regained his memory and is throwing a party to celebrate Dipper and Mabel’s 13th birthday and last day in Gravity Falls. Shandra closes the broadcast with Bodacious T announcing a new sport called "death ball."

At the Mystery Shack, Stan, Ford, Soos, Wendy, Candy Chiu, and Grenda finish singing Happy Birthday to Dipper and Mabel. The entire town has gathered to the Shack to celebrate as well. Mayor Tyler says it’s the least the town could do to thank the Pines for all they’ve done. Gideon says that thanks to the twins, he’ll no longer be evil and will open up his heart. It’s then shown that he tries to be a “normal” kid, but only succeeds in being bullied. Gideon then sics Ghost-Eyes and his other prison buddies on the bullies for revenge.

Soos tells Dipper and Mabel to make a wish. Dipper says that on his first day at the town, Dipper would have wished for adventure, mystery, and friends, but he now realizes he has all of that already. Mabel’s wish would be to shrink everyone down and take them home, but decides on something more feasible: having everyone sign her scrapbook. Mabel swears to never forget anyone in Gravity Falls, and breaks the memory eraser to prove it. Mabel and Dipper then blow out the candles on their birthday cake. Wendy declares the twins to officially be technically teenagers, causing her and her friends to chant enthusiastically.

Pacifica tells Dipper and Mabel to open the presents she gift-wrapped for them. They begin holding up their presents as Ford calls Stan away to talk to him privately. Ford says that he’s beginning to detect strange anomalies in the middle of the Arctic Ocean. He wants to investigate, but doesn’t want to do it alone. He personally asks Stan to come with him and give him a second chance, living the adventures they wished they had when they were younger. Stan agrees to the offer. When Ford wonders what to do with the Mystery Shack, Stan comes up with an idea and whispers it to Ford while Soos eavesdrops in horror.

As Dipper and Mabel look at their presents, Stan prepares an announcement. He says that due to his oncoming adventures with Ford, he’ll be closing down the Mystery Shack for good. The town is shocked, and Soos runs on stage and speaks against Stan. He feels that the Mystery Shack is a place that fuels people’s dreams and imagination, and if it’s shut down, people’s dreams will be shut down with it. Stan says there isn’t anybody to run the Shack in his absence, but then realizes that Soos would be the perfect replacement. Stan gives Soos his fez, proclaiming that the Mystery Shack is under new management. Abuelita moves in almost immediately.

A while later, Dipper and Mabel’s rooms are empty. The twins are at the bus stop with Stan, Ford, Soos, Wendy, Candy, and Grenda. Mabel says it’s time to move on from Gravity Falls, wishing goodbye to Candy and Grenda. Mabel wishes goodbye to Stan as well, happy he’s wearing a goodbye sweater she made for him. Wendy wishes Dipper goodbye as well, telling him that he means a lot to her. She exchanges their hats so they each have something to remember each other by. Wendy also gives him a letter for him to read the next time he misses Gravity Falls.

Finally, the last bus leaving Gravity Falls pulls up to the stop. Mabel realizes she’s said goodbye to everyone except Waddles. Mabel tearfully says that since her parents won’t let her bring him home, Waddles has to stay in Gravity Falls. Waddles attempts to follow Mabel, much to her anguish. Stan gets fed up and says that if he had to tolerate Waddles all summer, then Mabel and Dipper’s parents have to as well. He forces Waddles onto the bus and tells the driver that Waddles has to be able to ride. When the driver explains that no animals are allowed on the bus, Stan and Ford flash weapons at him, convincing him to let Waddles on.

Dipper and Mabel hug Stan, saying they’ll miss him. The twins walk onto the bus, getting ready to head into the unknown. As the bus drives away, Dipper and Mabel wave at all their friends. They wave back and try to run after the bus, eventually stopping. Dipper and Mabel look out the window of the bus. Various creatures wave at the bus as it drives by. Dipper begins a voiceover much like the one he did in the very first episode, talking about the mysteries of Gravity Falls. He encourages those who are curious about the town to come visit it and find their own adventure.

At some point in the future, McGucket officially moves in to Northwest Manor. Soos runs the Mystery Shack with Melody as his assistant. He wears Stan’s old costume and has made a statue of him in his honor, which frightens many of the tourists in the Shack. Stan and Ford pilot a boat in the ocean, fighting a giant squid. The boat is revealed to be named the 'Stan O’ War II'. Back in the present, Dipper opens the letter Wendy gave him. It reads “see you next summer,” with all of his and Mabel’s friends having signed it. Dipper smiles as the bus leaves Gravity Falls and the credits roll.

The credits show different scenes of Dipper and Mabel’s adventures with their friends in Gravity Falls, ending with them arriving back in Piedmont, California.

After the credits, Bill Cipher’s petrified form is shown in a real forest.
