Plunder Island Naturalist Society
From Monkey Island wiki
The Plunder Island Naturalist Society is, as its name implies, a society of naturalists on Plunder Island. They have put up informative plaques on Plunder Island, providing information about the flora, fauna and geography of the island. The society has also set out a Nature Trail on Plunder Island. The remains of a member of the society (most likely Mrs. Brinestoop) are found by Guybrush inside a snake on Plunder Island, leading Guybrush to remark on the dedication of the members. The society even manages to plant a sign about the snake next to it after it plunges from the trees and swallows Guybrush.
Another member has shared a similar, unfortunate fate, judging from a plaque this member wrote to describe a quicksand pit on Plunder Island: "Quicksand pits of this type are common throughout Plunder Island's nature trails. Many an unwary traveler has found himself trapped and unable to esca... uh-oh. Someone anyone please please help me I'm sinking!"
