How do you make a shadow chao in sonic asventure battle 2

1. Get a normal egg.
2. Hatch him with shadow.
3. Pet him a lot with Shadow. Don't pet him with sonic, knuckles or Tails.
4. Feed him only Green drives. You will need a whole lot of them.
5. (Optional) Give him lots of dark fruit. This will speed up the process.
6. Eventually, He will get in a Pear-shaped cocoon.
7. When he gets out, he will look kind of like shadow, but with green hair instead of red.
8. Don't worry. It will turn red.
9. Keep feeding him green drives and dark fruits, and keep petting him with dark characters.
10. (Optional) Enter him in a whole bunch of running races. He will win almost all of them.
11. Eventually his hair will turn red.
