You can get 5 Sonic Tokens from Chao Race. Just raise a chao then go to the Chao Race chose the first choice and then the place where your chao is. Then chose a crystal and win each one then a 5th one will appear and chose it. If you have trouble finding levels you have beat and want the tokens go to the main options at the chose the second option. You can go to any level you have beaten with out running around for it. This is good if you need to collect more tokens and it tells you which ones you have gotten and where. There are Tokens hidden around the world which shouldn't be to hard to find. I have 114 tokens and missing 6 with Sonic.
