This is a side-scrolling action platformer in which players assume the role of a humanoid earthworm (Jim) who must travel the galaxy to rescue Princess What's-Her-Name. Players run, climb, and bungee-jump their way through colorful platform levels, while saying things like "Yippie!," "Groovy!," and "Oh, yeah!" Along the way, they can use their own head as a whip to defeat enemies. They can also use a blaster to shoot at birds, dogs, blobs, and boss characters. Most characters burst into a cloud of dust or feathers when defeated; some burst into piles of "cartoony" bones and eyeballs; and others simply emit burp or flatulence sounds when their time has passed. After passing through levels named "Intestinal Distress," "Snot-a-Problem," and "New Junk City," players may elect to use a refrigerator as a counterweight to launch cows.
