I wanted to start a list of things people might of thought about adding to the mountable animals list. Spare you all the details, if you've got something that just isn't in existance and would make a nice contribution, yet don't have any intentions on building a zone well then please assemble your partial thoughts here.

My suggestion,
Tiny pink elephants - mountable for anything up under 100lbs.
( I just can't seem to bring myself to making it myself, hopefully someone else will with a bunch of pigmies in the forest)

Thanks for the concern.
have a good one.
