Chikuchiku

Hedgehogs are enemies in the game Donkey Kong on the Game Boy. They make their first appearance in world 8-1 in the Rocky-Valley. Just like Dotties, they walk around the environment in circles, walking up walls and on ceilings in the process. Unlike Dotties, however, they kill Mario if he touches them. They can walk at different speeds. Throwing the key at them does not hurt them.
