This version of "Earthworm Jim" lacks the hidden level "Who Turned Out the Lights?". It also lacks the Sega CD-exclusive level "Big Bruty". However, this version contains five new levels: "Cheap Chaps-Chopping Chips", "Locustomization", "Play Me Off, Gamepad Worm!", "Chips Chop Back!", and "Bump a Dumpa Diddle Doo".
