Mind Trap.Goku shakes off the slime, and blasts the worm, injuring it. The worms brother then shows up, and comically calls for their father, but instead of eating Goku, the father yells at his mischievous sons. Goku and the daddy worm exchange pleasantries, while Vegeta feels comically sick due to the worms. The worms point them in the right direction, but due to the damage Goku and Vegeta have caused inside Buu, Buu experiences great discomfort, and decides to evacuate his bowels. Buu creates a toilet in the middle of nowhere, and comically stinks out the surrounding area, including Dende and Hercule Satan. Goku, Vegeta and the worms are caught up a surge of liquid rushing through Buu's innards, and the worms declare it's "potty time!" A horrified Vegeta refuses to be expelled from Buu's body in such a way. He blasts a hole through the wall of whatever fluid tube they are sliding down and flies up through it, with Goku following. After a long journey, they finally arrive in Buu's head, where they encounter what appear to be Piccolo, Gohan, and Gotenks. These three begin attacking Goku and Vegeta, and even though Goku and Vegeta manage to defeat their mysterious attacks, they just get back up again and continue fighting. It seems Goku and Vegeta cannot win, but when Buu goes to a bakery and begins to eat some cake, the unstoppable opponents turn into desserts. They were just Buu's thoughts. Goku and Vegeta finally find them, who are trapped in cocoons, unconscious, but alive.
