2524-2525. Two Head

Two Head, also known as the Twins, were two conjoined crew members onboard the Flying Dutchman, under the command of Captain Davy Jones.
The being known as Two Head was two pirate brothers who resembled Siamese twins. The two brothers that were joined together when Davy Jones was captain of the Flying Dutchman were never actually born as conjoined twins. The reason why they are joined together is because that is the result of their eternal servitude aboard the Flying Dutchman. After Davy Jones is slain and Will Turner becomes the captain of the Flying Dutchman, the curse on the crew of the Flying Dutchman is lifted and they become human again. The two brothers become normal twins again and are no longer joined together. They were joined from the shoulder down, each one with one arm and a third leg ending in a stump where they were connected. Two further arms hung limp from their front and back. Their toes were cemented into calcified blocks by tiny parasitic crustaceans. The left twin had lobster claws growing out of his head, while his brother's eyes had transformed into those of a seahorse. They both had small beards of coral and eyes like polyps.
The Twins were present during Will Turner's game of Liar's dice, where one twin ate a piece of the other's shoulder. They later manned the Kraken Hammer. After Lord Cutler Beckett assumed control of Davy Jones, the Twins participated in the battle of Calypso's maelstrom.
