Chumly the Rocket Man
From the Croc Wiki, the Croc encyclopedia
Chumly is an unknown creature that lives in his icy lair on Ice Island, appearing in the level Chumly's Snow Den. He is the only boss that was not transformed by Baron Dante. Instead, Dante strapped a rocket to Chumly's back. Chumly's main attack is to drop down onto the ground and crush Croc. Chumly is arguably the 'easiest' boss in the game. He has three hit points.
