Also known as Hantu Penanggal it is a variation of vampire myths found in Malaysian Lore. Penanggal means "detach" and "remove". They are human during the daytime and only count as undead at night when they detach themselves from their body. In certain versions of the legend, Penanggal are old or young woman who uses supernatural means to obtain beauty. One can also become one through the influence of a curse or demonic entity. They love the taste of an infant's blood or the blood of a mother who has given birth. Those they feed on get a disease that is almost certainly fatal.
"A fairy rumored among Japanese folklorists to protect beehives in the jungles of Malaysia. It lives on the top of trees and watches over beehives. If you steal a beehive, it will attack. If you are caught, you will be killed, and even if you escape you will be frozen with pain, as if you were stung all over your body. At night, it floats around like a will-o-wisp and unleashes a stench that smells so bad you can't breathe."
