Earthworm Jim is a platform game starring an earthworm who battles evil with the help of an "ultra-high-tech-indestructible-super-space-cyber-suit". The game was developed by Shiny Entertainment, released for the Sega Mega Drive/Genesis in 1994, and subsequently for the SNES, Game Gear, Game Boy, Game Boy Advance and Microsoft Windows. Upon its release it was praised for its detailed animation, polished gameplay, and wacky absurdist humor; it became the first game ever to get a 100% review in Games Master magazine.
The storyline involves many colorful characters. Jim himself (a character designed by Doug TenNapel) was at first an ordinary Earth earthworm who did very earthworm-like things such as flee from crows and eat dirt. One day, in the space above Earth, the evil Psy-Crow had cornered a rebel spaceship pilot who had stolen an ultra-high-tech indestructible super space-cyber-suit, built by Professor Monkey-For-A-Head. The suit had been commissioned by the evil Queen Pulsating, Bloated, Festering, Sweaty, Pus-filled, Malformed, Slug-for-a-Butt so that it would make her as beautiful as her twin sister, Princess What's-Her-Name. In the ensuing space fight, the suit was dropped to Earth, and fell on Jim. By a stroke of luck, Jim managed to land within the collar of the suit, and it ended up mutating him into the large and intelligent (at least by earthworm standards) superhero he is today. Jim overheard Psy-Crow talking to Queen Slug-for-a-Butt about the scorch marks left by the suit, and how she would soon be as beautiful as Princess What's-Her-Name.
Jim thus sets out to rescue the princess, fighting many enemies along the way, such as Evil the Cat and Bob the Killer Goldfish.
