Part of Collab with close friend, namely to describe origin of belly maw I have, he even made little writing for story, here is him

"Walking through a rather nice clearing, our Servine friend seems to encounter a Delphox, of course though his first thought is to see if he can sneak himself a snack, but this Delphox is a lot smarter then he looks, and with a special spell in hand, blasts some sort of magic right at the Servine's belly, and suddenly his belly seems to almost open right up into a maw with a complete tongue and everything"
