Camel or Dromadary would be a little bit difficult to do. The farmer character would need to be moved up so that they are not sitting "in" the camel. Currently I don't know of a way to do this. I or someone else could make a camel, but it would be really small in comparison to the farmer. I could give it a shot though after I finish up two other mounts I'm working on.
