Summary :- While Yamato tells Naruto ghost stories to pass the time, they soon encounter a strange and abandoned ship floating on the sea matching Yamato’s description of a ghost ship from one of his stories. Following Yamato and Aoba onto the ship, Naruto finds a young cabin boy named Hishaku working hard and clarifies mundane reasons for the ship’s strange appearance even though his shipmates were all slaughtered by a gigantic sea monster called the Skeleton Crab. Eventually the Skeleton Crab makes its presence known and grabs Yamato whom Naruto, with Hishaku’s help in exploiting a soft-spot, saves by killing it with a Rasengan. Hishaku is then reunited with the ghosts of his crew and their captain before vanishing. To Naruto’s horror he later learns that Hishaku had long been dead and could not move on until his crew had been avenged.
