"The Descent" (虎穴に入らずんば... Koketsu ni Irazunba..., lit. "One Must Enter the Tiger's Den...") is the two hundred fifty fourth chapter of Dragon Ball Z and the four hundred forty-eighth overall chapter of the Dragon Ball manga.
Dabura flies up to Kibito, puts his hand to his face, and fires a ki blast at him, killing him. Dabura then spits at Krillin and Piccolo, who were unable to react to Supreme Kai's warning about his saliva and they're both turned to stone. Goku asks if there's a way to turn them back, and Supreme Kai says only if Dabura dies. Goku is glad it’s such a simple method. Dabura flies back into the ship, and Goku and Gohan agree to follow. Supreme Kai yells at them that it's exactly what the enemy wants, but Vegeta says they're no good at waiting, and follows as well. Supreme Kai reluctantly goes after them. The four of them enter the door, and fly down a long shaft, until they come to a large round room.
Supreme Kai tells them that the only way out of the ship is to defeat Babidi. Vegeta thinks he could just destroy the ship, but Supreme Kai protests, as a strong shock could wake up Majin Buu. Even without full energy, Majin Buu could kill all of them and destroy the Earth in a short time. Babidi is watching through a crystal ball, and tells Pui-Pui to go take their energy. Pui-Pui enters the room where they're waiting and tells them that Babidi is on the lowest floor. However, they won't get past him. Goku thinks otherwise, though.
