Evil the Cat was slated to appear as the boss of the "Fear" level world but was cut and replaced with Professor Monkey-For-A-Head. Despite this, his image appears on records in "Boogie Nights of the Living Dead" and is even advertised on a few of the game boxes. Additionally, Evil Jim, Earthworm Jim's evil twin from the TV series, was also reportedly a part of the game before being cut.
