Only 500 units were produced, either as a standalone cabinet or as an upgrade kit to existing cabinets (Atari part no. 136028). The game's background music appeared on the 1991 and 2003 release of That's Atari Music - G.S.M Atari Games 1. The player maneuvers Peter, a cartoon rodent, through various environments to collect objects and take them back to his nest within a designated time. Enemies, referred to as "The Gang", include cats, dogs, owls, and spiders, and must be avoided or stunned by throwing gems or collected objects. Each successive stage increases the number of objects to collect, reduces the allotted time to collect them, and adds more enemies.
