Skulbie

Skulbie are creatures that are skeletons of humans with a few added bones here and there.
They have large skulls and all of there bones are connected with a magic force of some kind. Skulbie don not have to eat anything and predators...well...who'd want to eat bones? Skulbie can detach some of their bones and throw them for fun, the bones then magically return to their owner. Despite being skeletons, they are not scary at all, they are actually pretty nice. They live in large groups and generally in dark places and/or in caves.
