>>44587877I mean bellybuttons are usually tame. I dont see issues with showing an animals bellybutton. And we see miltanks udder and a few tgc cards showing the topic.
My mistake for not seeing the book part, But a lot of the anatomical lore is shown in the dex.
So I just assumed.
The idea of not having a bellybutton shown is a fair reason to doubt that pokemon have no belly button. As pokemon like miltank have nipples showing.
