CS Eggs are eggs that can only be pruchased from the Credit Shop, and may only be avaliable for a limited time. Currently the only CS eggs in circulation are Liyure, Omni and Kioka, and there are none avaliable to buy in cash sop (so you have to buy them from other users.)

CS pets (which hatch from CS eggs) can only be hatched into three colours - natural, black and albino - and can only be dyed Gold and Silver. Black and Albino CS pets are currently the rarest creatu in Rescreatu and most difficult to obtain.
