The penanggal or penanggalan is a nocturnal vampiric entity from Malay ghost myths. Its name comes from the word tanggal meaning to remove or take off, because its form is that of a floating disembodied woman's head with its trailing internal organs still attached. From afar, it twinkles like a ball of flame, providing an explanation for the will-o'-the-wisp phenomenon.
The penanggalan exists by different names in every country of Southeast Asia. It is known as balan-balan in Sabah, leyak in Bali, kuyang in Kalimantan, palasik in West Sumatra, kra-sue in Thailand, kasu in Laos, ahp in Cambodia, and manananggal in the Philippines.
