Buu turns Chi-Chi into an egg and squashes it. Buu grows tired of waiting and threatens to be taken into the room in which Goten and Trunks are in, or else he will kill everyone at Sky Palace. Piccolo, knowing that he is too weak to fight Buu, takes Buu to Goten and Trunks with the hope that the boys have become strong enough to fight Buu. Goten and Trunks fuse into Gotenks and fight Buu. Gotenks is able to stand up to Buu, but neither side is winning.
Piccolo blasts the doorway in the room.
Then, he tells that without the exit, everyone will remain trapped in it forever so Buu can no longer kill any more people. Gotenks argues with Piccolo that they too have become trapped. Buu creates a fireball that produces a portal exit. He exits the room and returns Sky Palace. Super Saiyan Gotenks tries to create the same fireball that Buu created, but is too weak to.
