Looking for a specific coop split screen adventure type game?

my buddy and I played it a while ago and now I was goin to make my bro try it. haha. I can't remember the name of the game, but I am pretty sure it was on xbox 360. At the most, PS2 or XBox 360. It was a adventure type with characters similar to the jak and daxter and ratchet and clank games, you know, those types of adventure games? It was two different characters, pretty sure one was fat, and somethin with a wand / magic or something. lol sorry this probably doesn't help, it was not kameo though...
