I have Omega Ruby, and I believe that Gastrodon (West Sea) is exclusive to that game. If I get a Gastrodon (East Sea) and breed it on my ΩRuby, will the baby Shellos be East Sea, like its parent, or West Sea, which is exclusive to my game?
The Pokemon which came out of the egg will always looks like it's mother.So ,shellos will be East Sea .
