What Could Have Been: The prototype version of the game contains several (very buggy) removed levels, but also some other changes. Most notably, Ripper Roo was originally located at the end of the first island, along with Up The Creek. (This would explain his rather awkward placing in the final game, just 2 levels into the second island.) The fight is also somewhat harder, and his laugh is slightly lower-pitched. There were also "POW!" crates, which don't kill you (oddly enough), but make a pretty explosion when broken. A precursor to Nitro Crates, perhaps?
