Green Thing from the Planet Jupiter is a fast-paced two-player competitive chase game where players take on the roles of Cannoli, a crafty housecat, and Green Thing, a stranded alien engineer. Cartoonish chaos meets strategic gameplay as Green Thing scavenges parts from around the house to repair his UFO while avoiding Cannoli and his traps.

Collect all the parts as Green Thing, or stop him as Cannoli before his owner Zia Nina gets back home!

Green Thing must rummage through Zia Nina's house to find parts to repair his UFO. He wields his Jupiterian gun, which can stun, smoke out, and distract Cannoli as he explores the house.

Cannoli must stop Green Thing at all costs, before Zia Nina grounds him. He has access to a "CAT-ALOGUE", where he can select and place ACME traps throughout the level, like a glue trap, anvil, and box of TNT.
