Viral Chao

Viral Chao are chao that are unobtainable by just hatching eggs in Sonic Chronicles: in fact, you have to search the internet extremely deep even to find any cheat codes for cheating devices. even then if you don't have anyone to trade with, you're stuck by having all five of them. one of the (and possibly, first) first codes relesed to et then still required you to get many chao eggs(via cheat codes).how many chao you get even crashes the game. however, if you make sure to start a new file specificly for this, then trade with someone else, it's a win-win situation, as viral chao are NOT permanatly tradeable, meaning you can give you freind their chao back, geting the other to your file, and you're good.
