From Monkey Island wiki
Mrs. Brinestoop is the name on the reservation slip Guybrush finds in a Massive, Man-Eating Snake on Plunder Island. The slip is used to get into Blondebeard's Chicken Shoppe in Puerto Pollo. It's safe to say that Mrs. Brinestoop may have met her end in that snake. Assuming she was a member of the Plunder Island Naturalist Society her remains are likely the ones Guybrush found inside the snake.
