This Cannibal Woman was part of the Pelegostos Tribe.
Around 1729, Captain Jack Sparrow and his Motley crew arrived on the Isla de Pelegostos and were captured. All members of the Pelegostos Tribe were convinced that Jack was a god in human form, and planned to release him from his mortal coil by ceremonially ingesting his flesh.
This woman was seen anticipating the ceremony and was confused when Jack attempted to escape, likely thinking (as the other Pelegostos thought) that such a ceremony would be beneficial to a god such as they thought Jack to be.
During the ceremony, she was stationed with a Large Cannibal Woman and a Cannibal boy in a tent. When Jack Sparow turned up at the tent, he accidentally angered this woman by throwing a coconut into her face. The two women then started to throw fruit at Sparrow. However, Jack ended up pole vaulting over a cliff edge to safety. Her further fate is unknown.
