Devil's Head

Funfun (フンフン) is a member of the Brown Sugar Pirates in Wario Land: Super Mario Land 3. He is the leader of Stove Canyon and is the fourth boss in the game. Funfun is a giant stone head whose fighting style revolves around breaking blocks with his toungue, trying to get Wario to fall into a chasm and spitting rocks. Funfun is immune to fire, coins, and ground pounds, but the rubble his attacks leave behind are picked up by Wario and thrown at him to defeat him. His name seems to be taken from the word funshi, meaning "self-decapitation" in Japanese.
