A skin included exclusively for the Japanese versions of Ratchet & Clank: Up Your Arsenal and Ratchet: Deadlocked, the Santa Ratchet skin was added as a bonus Cheat (Up, Down, Up, Down, Square, Square, Square, Square) within the game which could be found by going to a certain web page or as a leaflet included inside the game box. The Sumo Ratchet skin uses a similar model.
