An evil spirit that lives inside a witch and leaves her body during sleep. Before the witch can die, they have to find somebody who will inherit the spirit by consuming some of the old witch’s saliva. These ghosts are powerful and fearful. If they succeed in possessing someone, they eat his or her intestines. The origin of Phi Pop comes from an old legend: Once upon a time, a prince who was fond of magic found the way to enter people’s bodies and take control of them. Once the prince said magic words and entered into the body of an animal. His servant, listening to those words, repeated them and entered the body of the prince. As a result, he became the prince. The real prince, entering the body of a bird, rushed to tell the truth to his wife. She then destroyed the servant’s body and challenged the false prince to enter the body of an animal. Then the real prince re-entered his body, but the servant was not able to re-enter his own body. From this time on his spirit goes from one body to the next, eating its intestines.
