Mappy
The player guides Mappy the police mouse through the mansion of the cats called Mewkies (Meowky in the U.S. version) to retrieve stolen goods. The player uses a left-right joystick to move Mappy and a single button to operate doors. The mansion has six floors of hallways in which the stolen items are stashed.
