One Piece: The Movie

The legend of the Great Gold Pirate Woonan remains intact, years after his disappearance. Many pirates search for his mountain of gold hidden on a remote island. Among them are Captain El Drago and his men. By hunting down every member of Woonan's former crew, they eventually take possession of a map to that hidden island. On their way there, they meet and decide to rob the Straw Hat Pirates, who, still lacking a cook, are close to starvation. A short fight ensues, during which Luffy, Zoro, and Tobio, a boy who ran away from home to become part of Woonan's crew, are separated from the other Straw Hats and their ship, staying afloat on the shattered remains of what at some point was a boat. Following the scent of food, they quickly arrive at a floating oden bar, run by Tobio's grandfather, Ganzo. El Drago and his crew land on Woonan's island, where they encounter Usopp, who, to evade being killed, convinces them, that he is a professional treasure hunter, offers them his help, and using their map, starts leading them around. Meanwhile somewhere else on the island, Zoro and Luffy, chained together for trying to eat-and-run, get lost and attempt to get back to the shore. With the help of Nami, Usopp gets away from the enemy crew. The Straw Hats meet up and take a closer look at the treasure map. They conclude, that Woonan's treasure must be hidden on the island's only mountain and set out to climb it. On their way up, they meet Ganzo, who reveals to them, that he and Woonan had grown up like brothers, in the same village. On top of the mountain, they find an empty house, with a secret entry to a basement. El Drago and his men arrive and are beaten by Luffy and Zoro. Then the group climbs into the basement. There, Woonan's skeleton is sitting in an empty room, a message for his old friend Ganzo written on the walls. With no gold left to find on that island, the Straw Hats set sail, resuming course for the Grand Line.

in my opinion this is pretty cool
