Hello, I'm trying to make a pet out of the Frillasaur. When I hatch my Scratchy Frillasaur with another pet in the kiosk, it always gives me the other pet that I hatched with, and not the Frillasaur back. I've always had trouble with this over the years, but is there a way to improve your chances of getting your pet back? Or a certain school or type of pet you should hatch with?
