I'm sorry for the such strange (potentially nsfw?) question. On their 3D sprites, it has a hole where the butt should be. I know Pokemon don't really have butts but, has it ever been confirmed if that's an open tail? or a butt? or a stuck out tail with a black dot on it? My friend says there's no way it's a butt, since y'know kids game, but that's all I can see.
so yeah, is that confirmed to be a tail design wise anywhere? what is it?
