In Japanese folklore, Gasha-dokuro (がしゃどくろ) or "Odokuro" are giant skeletons, often fifteen times taller than an average person. If a gasha-dokuro sees a human, it will grab it and bite its head off if it does not flee quickly. Gasha-dokuro are created from gathering bones from people who have died of starvation. The only way a gasha-dokuro can be detected before it appears is by hearing a ringing in one's ears.
