Mule Craze

For the longest time, I've been wondering, "why do mules get so much attention in the hobby?" That is, until my day trip to Gentle Giants. Among the hundred-something horses there, they also had two or three mules, one of which especially caught my eye. Now, I don't remember his name, so, for the time being, we'll call him Rob. Who dare hurt such a special creature such as Rob, let alone any
animal?

Okay, y'all, I think I need him as a model... Mold suggestions?

"Peekaboo!"

As you may have seen above, do y'all have any mold suggestions? I'm open to plastic or resin  : )
