Boneknappers are very picky about the bones on their armor. Once a year they will discard the old or broken bones from their scales for newer, stronger ones.
Boneshedder, like any other Boneknapper, has a coat of bones on his body. However, he has significantly less bones and more of his purple skin is exposed. His back is only plated with a few bones and most of his tail and limbs are uncovered. His tail has a club at the end that is made of several bones fused together into a rather regular shaped oval, with a few fragments of bone jutting out.
