We know the name give for it by SimGuruFrost is Leafbatpig.

Given those two facts it is clear it is a bat and a pig hybrid. Likely with the official name of "leafbatpig" but maybe not. So those saying it is a pig are correct as are those saying it is a bat. Calling it a leaf may also be correct. It is all those things at least in part.
Sorry to say I have not seen a screenshot of it in game. But the very concept makes me smile. I will have one. Heck, this is like Pokemon, Gotta catch them all. They even have Pokeballs. Just ask SimGuruRomeo. LOL
