In Hopping Mappy players control the Micro Police mouse, Mappy as he bounces on a pogo stick to run circles around pink cats, called Meowkies, who patrol either vertically or horizontally. There is also Nyamco, a cat who patrols in a zigzag pattern, but he needs to take occasional breaks. There are eight treasures that a player must grab to complete a round, except on the bonus round where the player will just want to collect all the balloons that he can. The main intrigue here is getting past a blockade of Meowkies.
