Batibat

Batibat is a vengeful demon found in Ilocano folklore. In Tagalog folklore, the creature is called Bangungot. The batibat takes the form of an ancient, grotesquely obese, tree-dwelling female spirit. They usually come in contact with humans when the trees in which they reside are felled and are made homeless, especially when their tree is made into a support post for a house. This causes them to migrate and inhabit what is left of their tree.
