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.
