Time Struggle

Chi Chi slaps Super Buu for she thinks he killed Gohan, and in retaliation, Buu turns her into an egg and crushes her. Goten vows to train as hard as he can for what Buu did to his mother. The boys enter the Hyperbolic Time Chamber and begin to train. Buu's patience wears off after thirty minutes, and he demands to fight his opponent right now. Piccolo reluctantly agrees to take Buu to the Chamber, but he takes the longest route possible, giving the boys as much time as he can. He telepathically warns them that he is bringing Buu to them so they can rest up in time. The boys seem to have developed a few new tricks, and they have planned their fight with Buu. Finally, Piccolo and Buu arrive at the chamber, and Goten and Trunks fuse together.
