Cooly Skunk is a prototype of Punky Skunk, from its earlier development for the Super Famicom. It was thought to be lost to history until a copy of a Satellaview demo was discovered at a used game store in 2020. It turned out to be not only a demo but a full build of the game, with many levels complete but unreachable.
This TAS plays a minor ROM hack that makes all of the levels playable, along with the final boss and end credits. This is similar to the hack used for Cheetahmen II to create its all-levels movie. These early versions of the levels are often simpler in design than their PlayStation equivalents, with many unique themes and graphics that didn't make it into the final game.
Ferret_Warlord utilizes the occasional jump glitch and wall zip to beat the game in a brisk 21 minutes.
