Episode 274 - Mind Trap

Synopsis: Goku shakes off the slime, and blasts the worm. The worm then calls his father, but instead of eating Goku, the father yells at his son. Goku and the worm become friends, and the worm points them in the direction of the four they're looking for. Goku and Vegeta 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 are winning the fight, their attackers don't take on any damage. Buu goes to a bakery and begins to eat some cake, which causes what appeared to be Piccolo, Gohan, and Gotenks to turn into cakes. They were just Buu's thoughts. Goku and Vegeta finally find their four friends, who are trapped in cocoons, unconscious, but alive.
