Shipwreck Sharks are menacing creatures seen in Alice: Madness Returns during the events in the Deluded Depths and Tundraful. They are large, menacing sharks made of discarded wood and have a constant hunger for wood, and find the Mock Turtle's very own ship, the HMS Gryphon as if it were a chunk of meat for ordinary sharks. They can only be destroyed with the ship's own arsenal.
