Ahh, this fellow has been waiting all winter for the BC to come back. xD It's been a while since I drew him, but I think he came about because I had the urge to draw something thick and not terribly cuddly. xD
Its been a while since he was drawn, so I dont remember EXACTLY what was going through my head. I think they're hard nail/claw/I guess hoof like substances. Probably not very mobile, dont protrude a whole lot, and there are three of them. Two on the front, and one on the back/side area as kind of a thumb claw placement I think I had elephants and rhinoceros on the brain back when I was sketching him.
