Pretty awesome custom creature. It's a pot-bellied ghoul rigged to the troll skeleton. Looks like a totally custom mesh and texture. Does anyone know who made them? There is absolutely no documentation that I can find associated with this mod anywhere. I'd love to see if it is a free-to-use resource or if I can ask permission to use it.
