1. Hatch a two tone black chao (Breed a normal and a black mono-tone chao from the black market)
2. Have it grow up to become Dark/Fly
3. Give it some run but not all the way so it is a Dark/Fly/some-run
4. Give it otter for whiskers (You can also give leopard if you want the right kinda tail, but wrong color)
I did this and this is what it looks like on PC
Don't think you can make this and have it crawl.
