Question for Sonic Adventure 2 Battle

Hey, I have a couple of questions
Please read this

1.How do you get a chaos chao? If you know more than one, tell me.
2.I beat the finalhazard boss and some freaks told me I can play super sonic and super shadow in other levels but I don't where or how.Help
3.This is the only way I know how to get a chaos chao...
I have to let it die 2 times in a pink cacoon then I give it every animal in the game. These are the animals.
-sheep(white and pink horns)
-raccoons(blue)
-skunks(black and white)
-rabits(pink)
-tigers(orange and stripes)
-cheetas(yellow with spots)
-gorrilas(dark blue with big arms)
-eagles(bird on fire)
-seals(white and light blue)
-penguins( blue with orange feet)
-bats(purple with no feet)
-peacocks(green with big feathers)
-vultures( purple with big wings)
-unicorns(white with a little pink)
-skeleton dogs(a dog with no skin, just bones)
-pigs(red with a snout)
-bears(purple teadybears)
-dragons(light purple with big wings and antennaes)
-parrots(rainbow)
-mink(little green bears holding pink shells)
-Fish( green with fins, there is one next to the guy at the black market)
ONLY if you know all the animals in the game, please tell me if I missed one or not.
Last question.

DOES THE DOCTER SAY ANYTHING BESIDES TELLING ME THAT MY CHAO IS VERY HEALTHY!
He scares me when he says "Oh, no".

Thanks
