K.O. wakes up screaming and crying, when Carol comes in, telling him everything will be ok. The next morning, K.O. has pancakes for breakfast, and then heads off to the Lakewood Plaza Turbo, where he finds a bunch of termites eating down the store and Boxmore. To cheer everyone up, K.O. decides to take his friends and his mother to CN City, along with Lord Boxman and Professor Venomous which they don't trust them at all, cause they're are their enemies. K.O. and his friends arrived at the CN City, they soon discovered the CN Bowling Ally is filled with lights which means there's a great party at the bowling ally. As they go inside, they reunite Steven and the Crystal Gems as he tells them about the crazy nightmare he had last night, but everyone thinks it's just a dream. Chef Hatchet rushes to CN Bowling Ally while shouting and panicking like a maniac, telling everyone of the "Return of the White Buffalo". Everyone ignores him, while K.O. is confused, and Chef Hatchet tells him that the legend of The White Buffalo has returned to this world, with that he shows everyone including K.O. some photos of the White Buffalo. As K.O. looks at the photo, he begins to recognize the creature he saw in his dream as he begins to panic, Chef Hatchet tells them that The White Buffalo lives on the other side of the CN world, The Wild West. Among the others suggestions is that someone should take on the beast, and that someone willing to do the job turns out to be Amethyst. Nearly everyone cheers, but K.O. is terrified and ask Amethyst to reconsider. Amethyst refuse to listen to his pleas and rushes out, so K.O., along with Radicles and Steven go after her. They arrived at the train station and they travel towards west, as they are on the train, Amethyst tells K.O., Radicles, and Steven about The White Buffalo claiming he's already attacking the Indian village, while they're talking about, they did not notice that Lord Boxman and his crew are on the train, they must've escape from Jasper and sneak into the train when they followed them to the Wild West, Shannon's plan is to throw the stink bomb in the train and she did, then they escape the train while no one else sees them. Soon enough, they arrived at Texas and spend the day there until tomorrow, they're search The White Buffalo somewhere in the mountains. During one night, K.O. is having a nightmare again where he is chased by The White Buffalo through the black hills of Dakota, and he was trapped again as the monster stabs him with his horn once again. K.O. then wakes up from his nightmare and start screaming in terror until Radicles throws a bucket of water at him. Radicles states to Amethyst that he told him that would quiet him down. Steven place a towel on the bed and comforts K.O. while stating to him that he must have had a horrible dream again. K.O. states it was and begins to explain how the dream went. Radicles interrupts midway and states that is really wacky, but they go to go. Steven scolds Radicles for saying that as nightmares can have lastings after effects. Steven explains the theory of how nightmares can do that to other people. The next morning K.O. and his friends begin to search for The White Buffalo in the Wild West. While traveling through the desert, K.O., Radicles, Steven, and Amethyst notice a wanted poster on a nearby tree. Looking at the wanted poster, Amethyst notice that it has Steven and K.O. displayed on it and the reward for their capture is 10,000 gold pieces. Hearing about the reward money, a creature rises from the bushes, revealing himself to be Mr. Hyde. Mr. Hyde, desiring the reward, begins to attack K.O. and his friends, only yo be stopped when he has a plunger thrown at and affixed to his face. Overhearing about it, Lord Boxman has a job for his son, Darrell to send him to prison. While trekking up a hill of sand, K.O., Radicles, Steven, and Amethyst are suddenly confronted by Lord Boxman's second-in-command, Sheriff Darrell, and his brigade of clones and horses. After hearing Darrell's plan to capture them, K.O., Radicles, Steven, and Amethyst begin to run for it, with Darrell and his clones and horses chasing them. Running from Darrell and his clones, K.O., Radicles, Steven, and Amethyst come to a dead end: a flowing river. With Darrell approaching quickly, Amethyst decides to use several logs flowing down the river as stepping-stones to cross it. After K.O. crosses the river, Steven and Amethyst does the same, as does Radicles who narrowly makes it. Seeing K.O. and the others cross the river, Sheriff Darrell orders his clones to do the same. Unfortunately, his clones fail to make it across and fall over a waterfall, leaving Darrell to cry and mourn their fate as well as his failures to capture the trio. Later, at a small town Kid Boxman is in the process of reprimanding his son for his failures in capturing K.O., Radicles, Steven, and Amethyst. After having several threats thrown at him, Darrell begins trying to calm down his father, saying he will hire every available bounty hunter to track down K.O.'s group. Later that night K.O. and the others arrived at the tavern, while there they meet Shaggy Rogers and Scooby-Doo who claimed that they saw The White Buffalo and they decide to use them as their guides, they went to the room and they all went to sleep, but K.O. couldn't take it anymore, he runs away from his friends and find the monster so he could kill him all by himself with out anyone's help. Steven tries to stop him from finding The White Buffalo, but he keeps running away from him and didn't know where he was going as he falls into a deep chasm, luckily he was caught on a branch and Steven attempts to save him with his jacket and pulls him up, then they realize that they we're lost and they decided to rest under a tree until they come and get them. Back at CN City, K.O.'s mother Carol grew worried about her son's disappearance somewhere in the Wild West, she suggest that they must go there and find her son, along with Enid, Mr. Gar, Dendy, Pearl, Garnet, Peridot, Bismuth, Lapis Lazuli, and Jasper.

Butch Steven and the K.O. kid" which causes Carol to faint, they couldn't believe that they're wanted criminals. They stopped at the Gold Nugget Restaurant so they can eat there while the gems (except Jasper) do not eat. Jasper pours water at Carol waking her up as Carol eats, they explain to her that K.O., Radicles, Steven, and Amethyst are going into a lot of trouble if they could get themselves hurt, they ask the waiter if he/she knows where their kids are, then the Waiter tells them that they were here in a minute ago when they're planning to stop the White Buffalo and Carol and the others rush out of the restaurant to rescue K.O., Steven, Radicles, and Amethyst. The Next Morning Radicles and Amethyst along with Shaggy Rogers and Scooby-Doo found K.O. and Steven resting in the tree and continue their search for the White Buffalo himself.

Somewhere in the desert, Carol and the crew are still searching for K.O. and his three friends, when Lapis Lazuli arrives back telling them that theres another Wild West City on the other side of the desert and they decided to go there. At the small town, everyone went to the tavern and eat there, then they were confronted by Shaggy Rogers and Scooby-Doo who they had seen K.O. and the others to look for the White Buffalo as they told them about it, then they decided to use them as their guides to help them look for K.O. and his friends. They continue their search in the forest, then they spotted a man riding a horse in the night, Jasper grabs the man and tide him up while Carol gets on a horse and ride it to get more so they could all go ride on them. Later they arrived at the farm where they found K.O. and his three pals, they became really angry when they realize they've been fooling around for nothing, they decided to ground them for a month not believing that they could catch the White Buffalo, suddenly K.O.yells out saying something to his mother that hurts her feelings, she scolds him for everything and Radicles tries to get them to calm down, but they're still angry at them, Rolf calms them down and they could get a sleep for the night.
