Chi Chi slaps Super Buu for killing 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 decides to take Buu to the Chamber, but he walks as slowly as he can, giving the boys as much time as possible. He mentally warns them that Buu is coming 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.
