I'd be more worried about it meeting Galli to be completely honest, but I'm... actually not sure what it is yet. It doesn't register in the Pokedex at all and even the nurses at the Pokecenters don't know what kind it is.

_{[Note to self, ask someone for help. Ford, maybe? Or a Jenny when he visits Jean.]}

There's two others popping up like it too. Jean has one that looks like a monkey.
