Hello. I can maybe help you with those Eggs again. I believe I still have you in my 3DS friendlist. Could you check? Simply delete me from your friend list, and add me again. If your 3DS adds me automatically, then that means you're still on my friend list. ^^
Anyway, about the Eggs. Unfortunately, I don't have a Toxicroak on my Omega Ruby yet, but I do however have those other three you're looking for: Sneasel, Excadrill, and Tyrantrum. :3
So yeah... Do you want me to help you with your Egg request?
