Davy Jones is a character who appears in the game. He is part squid, and part crab. He is a main enemy in Dead Man's Chest and At World's End (he is an in-game boss).
He is the captain of the ghost ship The Flying Dutchman, so he has the ability to breathe underwater. He also has the ability to go through green patches of sea life and exit out some other area of the ship or otherwise. Davy Jones has the standard attack of a sword. He is also very strong to pull heavy objects or throw people.
