there are none in sonic heros the game but there are some in sonic adventure and sonic adventure 2 battle i know because i have them all so who ever's saying that needs to quit becasue there are no chao gardens in sonic heros ok if you need any advice from a 14 year old my name is jessie you can email me anytime ok and you have to go to the chao lobby and you take care of them for sometime in the regular garden then after they turn to hero or dark you go outside the lobby and you see on your left dark garden and on the right hero garden ok gotz to go laterz!
