The battle bunny level is located in level 33 or 34 of the Caverns of Chaos. It is necessary pass through the level to advance through the main game/storyline, since the last three orbs are located below.
The layout of the level is fixed, with PC starting in upper right corner and stairs being in lower right corner. The level is designed to be a breeder trap, consisting of two long horizontal corridors connected in the left side; since teleport is allowed and walls are diggable, though, it is easy to find a shortcut to the opposite staircase.
Bunnies breed by essentially splitting (two new bunnies have about half HP of initial one), so some players suggested using them as healing targets for alignment boost. However, this tactic is needlessly dangerous.
- Battle bunnies, which can breed into more bunnies and mutated battle bunnies.
- Bugs the bunny master, who enhances breeding rate of bunnies while he is alive.
Corridors will have some randomly generated monster of appropriate DL.
