Dunk

Dunk is a rabbit that plays basketball in Wario Land II and is one of the bosses (of Anyone for B-ball?) in the game. Wario must jump on him (which turns him into a ball) and throw him three times into a basketball hoop before Dunk can do the same to him. Dunk will also throw basketballs, which both open Wario up to be jumped on and revert him back to normal. Judging by the skull on his shirt, it appears that he is a member of the Black Sugar Gang.

In Wario Land 3, a similar character who is possibly related to Dunk appears, the soccer playing boss Shoot.
