Oku

A Turkish monster that locks children in a bag.

Oku has no definite shape, which makes it even more intimidating. It is not entirely clear whether this term refers to a single creature or to a whole group of shapeless monsters. 

Most often, the role of the Ocu is reduced to a scarecrow used by parents to discipline their children. When a young man is caught behaving inappropriately, Oku intervenes.

Due to the lack of a specific image, the ghost is most often depicted in a black coat and with a large canvas bag. He keeps children captive here.
