Name Any animal that Pokemon never did.

[Chaoxys]

I really can't imagine a non-crappy pirate pokemon.
There was a really good grass Stegosaurus and water... Water Buffalo Pokemon some fan drew. Dinosaurs always look good Pokemon-ised. And although we have Tauros and Miltank another cow like pokemon would be cool.

A sheep Pokemon which stayed looking like a sheep would also be nice. I don't know maybe an alternative Flaffy evolution or something.

Is there a mole Pokemon (no I'm not counting Diglet, I mean one that looks like a mole)?

Yeah Drilbur or whatever his name is.
