One Piece (1999): Plunging into the Devil’s Sea! The Mysterious Skeleton Floating in the Fog!

In search of food, the Straw Hats attempt octopus hunting before discovering a barrel in the middle of the ocean. After opening the barrel, with fireworks launched from it, the Thousand Sunny gets thrown into the foggy Florian Triangle where it encounters a ruined ship with a living skeleton on it. While the others are unnerved, Luffy boards the ship with Sanji and Nami where they find the skeleton. After the skeleton introduces himself as Brook, Luffy immediately asks him to join the crew.
