I have a lot, and I mean a LOT of chao. To keep them organized, I sometimes use what I call "chao formulas". For example, I named one of my chao N:R:R.This stands for neutral, run, run. I see that as directions for making a Sonic chao. I need to give him run (green colored) chaos drives/animals, then evolve him as a neutral chao, and give him run (green colored) chaos drives/animals for his 2nd evolution. Just thought I would share this with you!
