Robo-Mouse

Robo-Mouse is an invincible enemy appearing in Wario Land 3 in The Stagnant Swamp and The Peaceful Village.

Robo-Mouse is, like its name implies, a robot with the appearance of a mouse and has claws. It uses its wheels to move and claws to destroy walls in its way. When it sees Wario, it will chase him and try to catch him with its claws. If it does, it will kick Wario out to a certain place out of a "caught" area.
