1)How do I get a group of chaos to play with the ball I won from chao race? 2)How do I get my chao to transform into a different type(running type,flying type,etc.)?
1. Chao will sometimes play with the ball if you throw it.
2. Give it animals or drives corresponding to the type you want it to become. Red animals/drives = power, green = running, purple = flying, yellow = swimming. If a chao's already evolved into one type, you can alter its looks by focusing on another type during a certain period of its life (ie. a Flying-type chao that's given red animals/drives after it's evolved will look different than a Flying-type that was given yellow animals/drives). After it reincarnates, you can make it into a completely different type no matter what it was originally.
