Mice[1] are enemies in Wario World. They are large mice that roll left and right in purple wheels. They are encountered exclusively in a few areas of the Sparkle Land level Mirror Mansion. Mice appear out of narrow doorways in walls in lowered areas that Wario cannot enter. If a mouse's wheels roll over Wario, he is damaged. Wario can defeat mice with punches, although to little effect, since mice spawn indefinitely. Empty wheels are also seen rolling by themselves in the same areas as mice, and mirrors can reveal which wheels have mice on them. Punching a wheel without a mouse in it does not have any effect.
