Nifoloa is a Samoan aitu, thought responsible for many spirit possessions.
In the village of Falelima there was a powerful devil who had a long tooth. After Nifoloa's death the tooth grew longer and ultimately grew under the Earth to all parts of the neighboring of Upolu. Many people were bitten by the tooth and this bite caused a bad sore. This evidence remains on the island of Upolu today. People who were bitten by this tooth are referred to as Nifoloa.
