Grimmy

Grimmy is an enemy in Croc: Legend of the Gobbos, which appear on some levels on the Castle Island. When Croc approaches one of them, they will begin to spin around while holding what appears to be an axe which will hurt Croc if he touches it. They cannot be tail-attacked but if you stomp close to them you can defeat them for a short time before they respawn.

Trivia

 * In the level Dungeon of Defright, there is a Popping Game mini-game in which Croc must use a switch with three buttons to 'pop' several Grimmies who appear in the corresponding passage. If he pops enough, he will earn a Gobbo.
