Now i'll explain the picture under this text.
Ok first you see a chao egg.Hatch it(hatching section).
Now after about 1-3 hours of care,(depending on how much nuts it was given.)You will hear some music.LOOK AROUND!One of your chao is going into a cocoon.Unless it's been their full lifetime, it will be blue.This means depending on the character and side they favour, they will follow the path of hero or dark, or neutral if they favor both.
Hero: Will have a inocent look, cute 0 shaped eyes, be generally white, and, if you gave lots of certain drives or animals, they will be a certain type of chao.(such as running or swimming.)This gives them a different appearance.They will also have a halo emotiball.
Dark:Will have an evil look, little evil eyes, be generally black, unless a certain type of chao.They will also have a spiky emotiball.
Those are the 2 forms of adult.Now, when their time comes at the end of their life, the cocoon comes again.If you treated them well, they will reincrnate into an egg (pink cocoon) with the same name, color and some animal parts.Will not be running chao, swimming chao, etc.
If you treated them bad, they will go into a gray cocoon and nothing comes out, the chao is dead.And that wraps up this section.
