From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Babidi's spaceship (バビディの宇宙船) is a long, cylindrical ship with a door on top and a large base.
During the Babidi Saga and the Majin Buu Saga, Babidi's spaceship appears hidden on Earth in the Southwest Forest.Dragon Ball Z: Buu's Fury, On each level (from top to bottom) Goku, Gohan, Vegeta and Supreme Kai were confronted by progressively stronger opponents, the first being Pui Pui, the second being Yakon, and the last being Dabura. On the bottom floor, Babidi was waiting with the Sealed Ball containing Majin Buu. The ship was ultimately destroyed by a wayward Majin Vegeta.
The Meditation Chamber is a chamber on Babidi's spaceship used for meditation by Dabura. It is only seen in one episode in the anime, when Dabura goes there to meditate to reach his full power before his fight with Gohan. It is the bottom chamber of the ship. It appears to be an empty room.
Babidi's spaceship is a battle stage in Dragon Ball Z: Super Butōden 3, Dragon Ball Z: Shin Butōden, and Dragon Ball Z: Supersonic Warriors 2. It is a stage in Dragon Ball Z: Buu's Fury, with enemies such as Majin Fighters, Majin Soldiers, Red Destroyers, and Laser Turrets inside.
