Ghost Chao ~ Give your Chao a Skeleton Dog then some Half Fish (this will give it a flame dot). After, give your Chao some Bats to make it's legs dissapear and then give your Chao a skull or pumpkin hat. It will then put on the hat and you will have a Ghost Chao. (It is best if you make this Chao Dark) Evil Bunny Footed Chao ~ Make a Dark Chao. Give some Rabbit's to it, then some Skeleton Dogs until it is left with only Rabbit legs. (This may not work first time as the Skeleton Dogs may take away the legs) Once it has only Rabbit legs, give it a skull hat and it will be an Evil Bunny Footed Chao. Cockroach Chao ~ Get a Black Chao, (either one from the Black Market or a Dark Chao) and give it some Dragons. After, give it some Skeleton Dogs until just the anttena of the Dragon are left on the Chao. Mystic Chao ~ Download a Jewel Chao from the SA2 Homepage (Looks best with the Green Emerald Chao). Then, give the Chao some Dragons. Once you have done that, give it Skeleton Dogs so it leaves only the Dragons horns and it's tail (That can be very tricky and may require a few attempts). Halloween Chao ~ Make a White/Hero Chao and give it a Skeleton Dog. Then give it Bats to make its legs disappear and lastly, give it a Pumpkin Hat.
