According to Fiji legend this is a giant with a maw filled with teeth like burning logs.
Flaming Teeth was a monster who terrorized villages,
eating people and livestock on a daily basis. Finally a group of warriors banded together to kill the evil giant. They managed to drop a huge boulder on the giant's skull. Flaming Teeth died, but the people brought tinder and branches to keep the fire going--and that is how the people of Fiji acquired flame.
