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.
The sharks are large in size (large enough to take down the Mock Turtles ship single-handedly) and have a similar design to most of the other creatures founded in Tundraful, the Deluded Depths and other aquatic sections of the domain. Their eyes are an orange/red color and glow, and they have a cross through each of their eyes.
They have fairly large, thin, pointy teeth that are unevenly spaced out. The body of the shark, although made of wood, represents no signs of "meat" anywhere. The wood is simply shaped to look like the sharks spine and ribcage. The shark has no innards or organs to take advantage of.
There are also two flags on the spine of the shark which have each been torn in half. They show the symbol of the most common black pirate flag with a white skull and cross bones. Their fins are similar to sails.
- Like most creatures in Chapter 2, the Shipwreck Sharks simply represent death at sea. They are created from the remains of Shipwreck as their name suggests, possibly meaning they represent ships that have been destroyed due to shark attacks. This is also backed up by the fact that these sharks still attempt to destroy ships constantly.
- Their fins look extremely similar to the Hollow Yves bow design of the Steamdress that Alice wears. It also matches the caudal (tail) fin.
