Plot
The prologue of the movie shows test footage of a live action island showing photorealistic CGI versions of the Flock and the Pigs, but it is interrupted by Bomb, who is sick and tired of those live-action/CGI adaptations based on cartoons, starts telling the audience that Warner Bros. must be dense. The Flock are going to the Warner Bros. studio, with several cartoon characters helping them get there, as they angrily lash out at Thaddeus Plotz and the Warner Bros., demanding that their movie must be traditionally animated. Plotz rudely refuses to do that, because live action films based on cartoons make more money and throws them out of the studio. Out of retaliation, Chuck calls Yosemite Sam that they've been hornswoggled and bamboozled that their movie is going to be in live-action, which the latter furiously comes in and threatens to shoot Plotz with his six-shooter if he doesn't turn the flock's movie to be fully animated. With complete regret and fear, Thaddeus Plotz quickly and promptly accepts their request to make their movie fully animated. Years later, we see The Flock and the rest of the Toons gathering for the first screening of the Angry Birds' first 2D animated movie.

The movie begins as the Pigs invites The Flock to share a gigantic feast at the All-Toon Companionship Festival, a time when the Flock, the cartoon characters, and the Pigs play fun games, crazy rides, and activities over Piggy Island. On his way, Bomb brings the Eggs along with him. Meanwhile, Edgar Baconhooves, the chef of pig city, complains about his failures to his lackey, Gramps, being unable to steal the eggs. When Gramps points out plan "105", a scheme which he has yet to attempt, Edgar decides to implement it. The festivities are interrupted by an invasion of monstrous crows commanded by the villainous crow Baron Harmful (Tim Curry), the leader of Crow Island, who uses explosive sapphire orbs to obliterate the entire Pig City to a complete wasteland. The Flock, the toons, and the pigs go into a fallout bunker before they're destroyed. When the birds see that the eggs are missing, they realized that their eggs have been stolen by Baron Harmful, and the courageous Bomb rallies them to retrieve their eggs and save Piggy Island.

After given missions from the Mighty Eagle, The Flock construct a boat, bringing their slingshot, and embark on a journey. After completely escaping and outsmarting Vicky, Dick Dastardly, General Skarr, and Plankton, who align with Baron Harmful, The Flock reach a peaceful island called Birdhamas filled with other birds. After coming to the conclusion that they have to complete their journey due to being ‘angry heroes’, The Flock decided that they won't give up as King Matthew, Nigel, Richard, Louis, and Ross arrive and Professor Mario Pigsworth upgrades their boat. They make camp in the island, after the inhabitants of Bird Town accept that they'll help, much to Bomb's delight.

After going back to Piggy Island, the Flock discover that the mastermind behind Baron Harmful's arrival is their archenemy, Edgar the Chef Pig, Don Bacon, and his assistant, Patsy. Bomb and his flock are ready to beat Edgar and his goons, but Baron Harmful stops them and throws the Flock (sans Poppy, Willow, Dahlia, Luca, and Gale) into a portal. Bomb and his friends, now animated in stylized CGI, find themselves at New York City in the real world, as they have to go find shelter in a hotel. While looking for a place to sit, Hal begins to lose hope and becomes depressed. After seeing him down on the dumps, Scarlett Johansson motivates Hal to never lose faith on his friends and never give up, restoring his confidence.

Seeing his friends enter a heated argument, Hal manages to successfully stop this with a rousing speech. The Flock resolve their differences, while they wonder how they get back to Piggy Island. Fortunately, Sofia Vergara and Eddie Murphy appears and offers them a slingshot. They managed to launch the Flock back to Piggy Island.

The Flock return to Piggy Island to save the captive pigs and toons and attack and defeat Baron Harmful by firing themselves over his colossal ship using their giant slingshot. Hal sees that the Flock has been cornered by Edgar and his army and is very furious about it. Hal launches himself via slingshot with no mercy, lets out a massive bull roar, and attacks Edgar and his mooks to save his flock. Edgar begins to have a bit of an existential crisis, shuffling towards Bomb on his knees and desperately asking if this constant war between birds and pigs was all there ever be, to which the latter responds with an awkward shrug. However, Baron Harmful reveals his plot to use his sapphire bombs which are revealed to be loaded with dip to destroy Piggy Island, so that Piggy Island will be extinct from the Tooniverse forever, much to Edgar's shock and dismay. After an argument, Baron Harmful betrays Edgar, calling him a "sniveling egotistical swine" and throws him out of his ship. The Flock save Edgar from falling and reunites with the Eggs. Edgar apologizes to the Flock, saying that he only now understands why keeping the Great Egg War going is a bad idea. Edgar and The Flock work together to beat Baron Harmful, but to no avail. Baron Harmful traps the Flock and prepares to destroy them.

Just when all hope seems lost, Bugs Bunny calls in Winnie and her flock, the pigs, and every single toon, including the Looney Tunes, Garfield, the Mystery Inc. gang, Woody Woodpecker, The Nicktoons, Finn and Jake, Steven Universe, Mordecai and Rigby, The Tiny Toons, the Warner Siblings, and Rocky and Bullwinkle to arrive and help the Flock. An all-out war broke between Baron Harmful's army and the Flock. All of the birds, toons, and pigs fend off Baron Harmful's henchmen while Edgar keeping the eggs away from him. The Flock battle against Baron Harmful, who is flattened by Terence, but survives, exposing him as a very deranged psychopathic bird that can shape-shift into many ferocious animals. Baron Harmful manages to hurl a box of TNT at the flock, but Hal throws a can of sardines in his way before he throws the TNT, summoning the Mighty Eagle, destroying his ship. An vengeful and deranged Baron Harmful yells at the Flock that he will return to try to wipe Piggy Island off the face of the Tooniverse. In the middle of his rant, however, Chuck drops an anvil on Baron Harmful, which knocks him out. King Smoothcheeks and the pigs stand before the defeated crow and Hal grabs Baron Harmful by the crest and spin him around before tossing him into oblivion, while Don Bacon and Patsy are arrested for their crimes against Piggy Island. The Flock and Edgar rebuild Pig City with the help of the Blues.

The All-Toon Companionship Festival resumes, as Hal finally gets the recognition he deserves and is hailed as a hero along with the Flock in gratitude when Bomb gives out a speech about how Hal is not only the brains of their team, but also in fact the heart and moral center of the Flock. While being praised by the Pigs and the toons, The Flock even forgive Edgar when they sees him sulking in sorrow, feeling regretful for what he did, and he befriends them with a makeshift sun visor for each egg. Edgar remarks that betraying his kind was the dumbest thing he's ever done. Bomb, Red, and Chuck shows him a montage of him stealing the eggs and Edgar even admits that that, was the dumbest thing he's ever done. The Flock celebrate by protecting the eggs together and are now welcomed by the Toons, who now begin to acclimate themselves with the rest of the birds and pigs (even the old inhabitants of Aviantopia move in to Piggy Island) in various activities for life, Bomb shows a sign reading "Happy ending ain't it?"

When the film ends, Silver insists on watching it again. Chuck tells her that they'll watch it again tomorrow until The Pigs, Lucy and Patrick (Chuck's mother and father), Winnie, Winnie's entire flock, and the rest of the toons want to watch the movie again as well, following an epilogue narrated by the Pink Panther detailing the fates and whereabouts of the toons after the film's critical success.

A mid-credits scene shows The Flock welcomes Winnie and her gang to Piggy Island.

Development
Following the success of Angry Birds X, Rovio Animation and Cartoon Network Studios announced that they would make a movie adaptation based on Angry Birds X in July 31, 2015. Originally, Columbia Pictures owned the rights to the movie and were looking to make it a live action/CGI hybrid a la Alvin and the Chipmunks and the Smurfs directed by Raja Gosnell and produced by David Kellogg. Until in August 13, 2015, Warner Bros. Pictures got the rights to the movie, watched, , and , and decided to make it a fully 2D-animated movie with live action scenes mixed in. Filming began on March 1, 2016 and wrapped on August 3, 2016. Rubber mannequins of the Flock would portray the animated characters during rehearsals to teach the actors where to look when acting with "open air and imaginative cartoon characters".

Joe Dante convinced Disney, MGM, Paramount, Universal, Twentieth Century Fox, King Features Syndicate, Mattel, Bagdasarian Productions, Nintendo, Nickelodeon, Sega, Turner Entertainment, Paws Inc., VOOZ Character System, Peanuts Worldwide LLC, Film Roman, Allspark Animation, and Xilam to lend their characters to appear in the film, the same way Spielberg convinced Warner Bros. and the various other companies to lend their characters to appear in .

Animation
The film's hand-drawn animated segments are animated by TMS Entertainment, using Toon Boom Harmony. Warner Bros. and Rovio also hired, Bruce W. Smith, and to supervise the 2-D animation when it blends with the live action environment.

According to art director Andrea Torrejon, they still wanted to keep to the look and feel of the television show, in which the use of Toon Boom Harmony enabled them to add "simple yet impactful changes" to the designs for the big screen, such as depth and shadows for their eyes, and crests and the impression of flowing fluffy feathers on their plumage.

Animation services will also be provided by Blue Sky Studios, who hired 3D animators with a passion for 2D animation for the project. Following the strategy of basing the animation off a stylized 3D/CGI VFX modeling medium through a 2D finish by creating innovative rigging, animation techniques used to create 2D animation, and custom tools such as lighting and rendering, resulting in the film's 3D/CGI animation maintaining the look and feel of 2D animation and Sony Pictures Imageworks is provided for the live-action objects the Flock had to interact with in the film.

Unlike other live-action/animated hybrids after Who Framed Roger Rabbit and Space Jam, the animation of the characters followed the same steps as Roger Rabbit and Space Jam.

 * The Teen Titans are depicted and portrayed as their 2003 animated counterparts.

But most noticeable is Mindy Cohn as Velma Dinkley. Mindy did Velma's voice from 2002 - 2015.
 * While the movie is going to be a Roger Rabbit-esque film with the 2D animation feeling more prominent than Who Framed Roger Rabbit, the animation treatment, when the Flock gets transported to the real world, will be cel-shaded CGI animation that will have the look and feel of 2D animation, promised to be in the vein of animated movies based on cartoons, while being more fluid, in both the character designs, and the overall character animation.

Cultural references

 * The scene where Ralph T. Guard trying to eject the Flock out of the Warner Bros. studio is similar to his portrayal in Tiny Toon Adventures where he guarded the Warner Bros. Studios, and was often at odds with the Tiny Toons, usually Plucky Duck.
 * Throughout the beginning is a giant middle finger to live-action adaptations of cartoons from every toon protesting Warner Bros. to make the Flock’s movie 2-D animated, to Yogi Bear and Scooby criticizing their live action movies, Shaggy chastising Matthew Lillard's portrayal of him again (being a reference to Looney Tunes: Back in Action), Finn, Chowder, and Flapjack agreeing to never make a deal with Hollywood to make a live-action adaptation, and Yakko telling Wakko and Dot that the Flock have got the "live-action treatment".
 * When The Flock came across Freddie Prinze Jr., Sarah Michelle Gellar, Linda Cardellini, and Matthew Lillard and Jay, Jake, and Jim asked if they had any regrets. They replied "Scooby-Doo, maybe.", possibly a reference to Zombieland, where Bill Murray actually regretted starring in Garfield.
 * One scene has Fifi La Fume interacting with Gumball Watterson, Muscle Man, and Peridot, with Muscle Man roasting Fifi La Fume for hiding in the food dish cover on a serving cart, a reference to Tiny Toon Adventures: How I Spent My Vacation.
 * The scene where Blossom, Bubbles, and Buttercup telling Thaddeus Plots to make the Flock’s movie fully animated, with Bubbles pleading Plotz to not let it bomb at the box office is a nod to how The Powerpuff Girls Movie bombed at the box office
 * The scene where The Flock spot 7-Eleven is a nod to the Walmart scene in Looney Tunes: Back In Action.
 * When Bugs Bunny mocks Thaddeus Plotz, it’s a reference to the Looney Tunes short, "Wabbit Twouble", when Bugs Bunny mocked Elmer Fudd.
 * When the cartoon characters and the Flock see Elmyra Duff, they either groan or kick her out to the curb which is a reference to how the fans of Tiny Toon Adventures hate Elmyra Duff.
