Bloody Bones is a bogeyman feared by children, and is sometimes called Rawhead and Bloody-Bones, Tommy Rawhead, or Rawhead. The term was used "to awe children, and keep them in subjection", as recorded by John Locke in 1693. The stories originated in Great Britain where they were particularly common in Lancashire and Yorkshire, and spread to North America, where the stories were common in the Southern USA. The Oxford English Dictionary cites 1550 as the earliest written appearance as "Hobgoblin, Rawhed, and Bloody-bone".
Bloody-Bones is usually said to live near ponds, but according to Ruth Tongue in Somerset Folklore, "lived in a dark cupboard, usually under the stairs. If you were heroic enough to peep through a crack you would get a glimpse of the dreadful, crouching creature, with blood running down his face, seated waiting on a pile of raw bones that had belonged to children who told lies or said bad words.”

It's form is made of the discarded remains of pigs and cows, the bodies of children, and grown adults if it gets large enough to consume them.
