All right, I know I just asked about the bubble thing, but I forgot to add this: One of my Chao, Gamma (red egg, in case it matters) has turned into a mini flamethrower. He literally breathes fire! How did this happen, and could it happen again? (Hee hee hee...)
You must have given it a dragon small animal at some point. Dragons give chao the ability to breath fire; but they'll only do it when they feel like doing so.
