To get a Chao that looks like Chaos you need to get a regular Chao, and make it rencarnate 3 times. Then after that happens, you must give that Chao every animal in the game, then the Chao should start to evolve. To make sure the code worked sparks of light should start popping out of the Evolution Egg (the egg chaos go into when they mature). NOTE: You cannot alter a Chaos Chaos' apperence no matter how many animals you give it.
