Well your first come so first serve.
I don't mind if you ask for a shiny in the next region you decide to goto.
Egg's are available forever so you will get one of each if you want.
Hey. I'm gonna have Aaron go get a Bulbasaur egg. Can it please be shiny? If you say yes, I promise it'll be the last shiny until like, Sinnoh or later.
How long are the Eggs going to be available? Because I want Aaron to get a Squirtle egg too when he's in the area, but if they're gone by then... oh well.
