 The Leyak is a similar being from Balinese folklore of Indonesia. A Kuntilanak or Matianak in Indonesia, or Pontianak or Langsuir in Malaysia, is a woman who died during childbirth and became undead, seeking revenge and terrorizing villages. She appeared as an attractive woman with long black hair that covered a hole in the back of her neck, with which she sucked the blood of children. Filling the hole with her hair would drive her off. Corpses had their mouths filled with glass beads, eggs under each armpit, and needles in their palms to prevent them from becoming langsuir. This description would also fit the Sundel Bolongs.
