Here are chao expressions.
1. If your Chao simply has a dot, halo or a spiked ball floating above its head, your
Chao is in its normal state and is probably not thinking of anything in particular.
2.If your Chao has a large heart floating above it's head, it is
very happy. You may have done something really nice or it might just be doing something it enjoys doing.
3.A Chao with a question mark floating above its head means that the Chao is thinking about
what to do.

4.If your Chao has an exclamation mark above its head, it means that he is excited about something
or that it has been surprised by something.
5.A Chao with a large tornado swirl above his head means it is very upset with something or
someone. It could also mean that he is tired, which was probably a result of something waking him up during a nap.
6.A Chao that is laying down with its eyes closed is asleep. Try not to wake it up,
since it will make your Chao quite upset... and tired. Sometimes Chao sleep sitting up, so careful not to mistake it for an
awake Chao.
