Cabbage Cavern is a large network of underground caverns underneath the surface of the Mirror World. Although the majority of the level is on the land, a lot of swimming through narrow passageways is required in order to find most of the treasures in the level. The outskirts of this level take place on the grassy surroundings of an underground lake, while the deeper caverns connected to Olive Ocean are a unique purple color. The boss of this stage, Moley, awaits Kirby deep inside a trash-infested tunnel.
