I'd like a list. How do you get all the special chao?

Have it specialize in one of the catagorys (running, power, swimming, flying). Pick a catragory and raise the stats just in that one catagory real high and your chao will look different from a normal chao. An example is lets say you go for a swimming chao, give it ALOT of yellow chaos drives. And eventually it will master in swimming and have HUGE ears. You can also have a hero or dark chao if you didnt already now that. If you wantr a hero chao raise it with only hero characters (sonic tails and knuckles). For a dark chao do the same with dark characters (shadow rouge and eggman). To get a chaos chao have it reincarnate twice and give it one of every animal.

The MOST special of all chaos are the chaos chao, there type are chaos, THEY ARE IMMORTAL(never die in case you didn't know that already) But they are hard to get and you have to be like a lifeless person to do this really, they have to die twice DONT GIVE THEM ANY ANIMALS, then on there 3rd life give them one of every animal, then dark fruit for the devil chaos, then the hero fruit for the angel chaos, and a chao fruit for the chaos(looks really cool) you can actually see these chaos chao in the game, it's the last chao in the dark and hero races, and the final challenge in the challenge mode thing is the normal chaos one, I have all three of them, the easiest way to make them die twice to go to the 3rd life so you put the animals on is to go up to the gate by the tree(to the RIGHT of it when you're lookin at it) go up to it and drop you're chao right up agaisnt it, he will sink so only his head is showin, then surround him w/ many fruit, this should keep him from walkin around, so if you WANT to leave it on all night to get some hours of life on the little guy w/ out him feeling lonely if he comes up to you wanting to be loved, cause he has to love you to be brought back to life, but thats if you want some really special chao, otherwise do what he said above
