The Polong is said to be a small female creature that’s about an inch tall. The creature could be attracted by gathering the blood of a murder victim in a bottle during the 17-day ritual. One would wait for the sound of young birds chirping, which was a sign that the Polong had taken residence in the bottle.
The Polong was fed by cutting a finger, inserting it into the bottle, and allowing the Polon to suck the blood.
In return for a daily source of blood, the Polong would perform a variety of tasks to include attacking one’s enemies.
If a person was attacked by a Polong, wise men were called in to exorcise it and attempt to figure out who sent the creature. Deaths were usually attributed to the attack of a Polong who remained unexorcised.
