Cave master

Cave Master is an optional boss in Wario Land and Wario Land II. He appears as a large, warthog-like creature. He is a member of the Black Sugar Pirates. In Wario Land, he attacks by charging at Wario — Wario must avoid the attack and ram him in the back, pushing him in the small pit on either side of the small arena. After being knocked off three times, the beast is vanquished. If Wario, however, is pushed into the pit, he must backtrack and start the entire fight over again. Like his name states, he is found inside a cave.
