When your Chao curls into a cocoon for the first time, it comes out as either Hero, Dark, or Neutral. This affects how your Chao evolves for the second time.
When your Chao evolves into one of the 3 types, it changes according to what colour animals/drives you have given it the most. This is its FIRST evolution.
After, if you give it more animals/drives. It will change again depending on what colour you have given it the most. This will be its SECOND evolution.
However, for the second evolution, your Chao will not go into a cocoon. It is just a change that will take place gradually as you give it more of a certain colour of animal/drive.
It may take some time to achieve the second evolution but it is worth it as you can get a huge variety of different Chao!
