Bobobo-bo Bo-bobo (2005)

Season 1: Episode 37

While Bo-bobo and the others have safely arrived in Holy Guacamole Land, they soon realize the danger of a park where attractions can blow up on you! At least everyone can find refuge in the "Kids Area", where everyone can relive their childhood...and Bo-bobo, Don Patch and Jelly can create their own rock band. No one told them about the adult villain in the park that can make them relive their worst nightmares, but the kid fighters can still have fun, kick butt, and even fuse into...a badly drawn warrior!
