Wild Shaped

Druids can wild shape into animals they have seen, which seems like a pretty casual knowledge. I’ve seen a tapir in a zoo, but I don’t think I’d have a innate knowledge of their biology or detailed comprehension of their anatomy. And after a few years, that mental knowledge might drift and I might and my version of a “tapir” might be a comical exaggeration with some weird biological variations. Does it have toes or hooves? A long tail or short? I have no idea, and it might get weird.

And yet druids can’t really “customize” their animal forms.

But if they could, one might expect animals to be a little more humanoid, as that’s the form druids are comfortable with. Or… less humanoid for more aberrant druids.
