Greenfist

Greenfist was a dinosaur-like boss that appeared in Wario World. He was the first boss. To beat him Wario had to punch him enough times. This enemy's attack was to get angry (he turns red) and would start punching everything. If Wario beat him, Wario would get a lot of coins. He was one of the two mini-bosses in Excitement Central before the SandWorm.
