Tiyanak

Tiyanak are babies who died before receiving baptism rites. After death, they go to a place known as Limbo, a chamber of Hell which unbaptized dead people fall into, and are transformed into evil spirits. These phantasms return into the mortal realm in the form of goblins to eat living victims. The tiyanak can also be the offspring of a woman and a demon. It can also be an aborted fetus which comes back to take revenge on its mother. Most Tiyanaks are said to live in forests. If they see a human, they transform into what looks like a normal baby. When the person notices the Tiyanak and comes near to take a look at it, the Tiyanak changes back to its true form and eats its prey. And since they often seen coming out of trees it may also refer to Tboli legends, Tibolis are known for hanging their infants in trees who died after birth.

The Tiyanak (also Tianak or Tianac) is a vampiric creature in Philippine mythology that takes on the form of a toddler or baby. Although there are various types, it typically takes the form of a newborn baby and cries in the jungle to attract unwary travelers. Once it is picked up by an unfortunate passerby, it reverts to its true form and attacks the victim. The tiyanak is also depicted to take malevolent delight in leading travelers astray, or in abducting children.

While various legends have slightly different versions of the tiyanak folklore, the stories all agree on its ability to mimic an infant, with its ability to imitate an infant's cries for luring victims.[3] In some legends, the Tiyanak may take the form of a specific child.
