Will players outside of Europe be able to hatch Mime Jr?
Mr. Mime is only available in Europe, a Pokemon that's good for nothing except when you're looking for great/excellent throws.
So what happens when gen 4 arrives and Mime Jr is presumably available in eggs? Will only Europe be able to hatch it? Niantic would be trolling us Europeans if they let the rest of the world hatch Mime Jr while Europe still has to see this thing in the wild every day.
I would hope instead of this Niantic removes Mr.Mimes regional exclusivity, making it an uncommon wild spawn (such as Wobbuffet) and allow the world to hatch Mime Jr like any other baby pokemon.

i dont know but hoping for the best in almere (nehterlands) its horrible i catch like too many mr. mimes but i have been thinking bout this. i hope they will trow in the shiny of al gen 1 starters and they will let mime jr just spanw like a regular mr. mime and let mr mime never spawn in wiild so a spawn bann and if you want a nother mime you just have to evolve mime jr thats what i hope probs not but ok
