Well I don't know how this happened, but somehow I lost the Grimer egg (either that or it was a Koffing egg -- the last egg just hatched as a Koffing). Guess I can't keep track of my poison sludge pokemon lol. Is there anything else I can give you as a third?
Hey I have two of your pokes hatched. I'm having trouble finding the Grimer egg (I traded the muk a while ago). Do you want to wait for me to find it, or do you want to do a 2 for 2 instead?
