This is what happens when you take the least-sane of the Skull Bhunees in CoV, and give him a new costume option.
Briar Skull Bhunny. Incidentally, not all of those diamonds are stitched together completely, since he -still- tends to get 'prickly' at times. (Yes, more prickly than a monstrosity covered in barbed wire might be at first glance. No really. Fine, I'll prove it.)
