Vegeta starts to beat up Pui Pui with no effort. To give his fighter the advantage, Babidi changes the room to mimic Pui Pui's home planet, where the gravity is ten times that of earth's. Unfortunately for Pui Pui, Vegeta trains at hundreds of times earth's gravity, and he easily destroys Pui Pui. They move on to the second level where Goku will fight Babidi's pet monster Yakon.
