There's two different versions of the Bullebak (also known as the Bulleman or Bollebak). In Gelderland it was believed the Bullebak was a creature that came out at night to scare people with its loud roaring noises. In Utrecht and a large portion of Holland however, the Bullebak was known to be a Child Terror. The water demon came equipped with a big hook, which he used to grab children from the waterside in order to drown them. It is said though, that once children got into the water, they could see a palace and countless of beautiful lights and stars. The creature was also known in Drenthe and Overijssel.
