Dragon Ball Kai • S07E48 : Gotenks' Ace in the Hole! Transformation! Super Gotenks 3!
Hysterically upset at the prospect of being trapped in the Hyperbolic Time Chamber forever, with nothing to destroy and no candy to eat, Super Buu starts to scream. To everyone's surprise including his own, his screams become so powerful that they create a hole in the barrier between the dimensions of the chamber and Earth.
