I think they need a name they are just a large herbivore beast of burden that is ready for transport. Give them a name I did not come up with one. There are elements of warthog goat and horse and elephant in them so seems a cross between a pachyderm and a deer? They were fun to do they were sort of a random critter thing I do once in a while.
Choteks sound good to me.
