Having seen what Noby Noby Boy can do, I'm not sure I'd trust him around my cat. Fortunately, the Noby Noby Boy pictured above is a fake version, knitted by someone called "Pudgeeagogo" on the European Playstation forums. If you think your cat might enjoy a Noby Noby Boy companion that won't eat him and then poop him out, the instructions are here.
