Penanggalan

The Penanggalan is a variation of the Vampire from Malay. During the day they appear as normal people, but at night the head will detach (with trailing entrails) and fly about seeking victims. The Penanggalan usually chooses newborn mothers and small children to prey upon - when a child is born the creature uses an abnormally long tongue to lap up blood from the mother. The victims of the Penanggalan usually die of strange diseases, and become Penanggalan themselves.

This creature is called by many different names in surrounding countries:

Indonesia: Leak
Thailand: Krasue
Cambodia: Arb

Unlike these similar creatures, the Penanggalan is always female.
