Massive, Man-Eating Snake
From Monkey Island wiki
The Massive, Man-Eating Snake is a ferocious reptile that lives near a cliff on Plunder Island and attacks people on sight when they come too close. The Plunder Island Naturalist Society has this to say about this animal: "This fantastic reptile is one of Plunder Island's most dangerous and beautiful predators." Strangely, this sign appears beside the snake between when Guybrush arrives in the area and when he is eaten.
Many exotic items can be found inside the snake, including a Fabergé egg, vacuum cleaner attachments, an encyclopaedia with only one legible entry ("compass"), the remains of a naturalist, a reservation card to Blondebeard's Chicken Shoppe, and several breakfast foods. Guybrush can combine some syrup with an ipecac flower to make syrup of ipecac, a purgative, with which he can ensure his escape from the snake's belly.
