Penta is a penguin and is a secret racer only available by code in Crash Team Racing. He is the best playable racer in the game and the second best of all racers (Oxide is the best, but he is unplayable). He has also made appearances in Crash Bandicoot 2 as an enemy that you must outrun. He also appears in Crash Bandicoot Warped that you save from being toasted by the second boss.
