The Chewong people of Malaysia say that there is a vampiric creature or spirit that lives in the pandan tree called the maneden. If anyone attempts to harm the tree, even so much as to cut the leaves that grow on it, the vampire will violently protect its home and defend its territory. If the attacker is a man, the maneden will latch on to his forehead or elbow; if it is a woman, her nipple. Once it has a firm grip, it will begin to drain the person’s blood. Before the person loses too much blood and dies, the maneden can be lured off if offered a nut or some other suitable replacement.
