One Piece Movie: Baron Omatsuri and the Secret Island

The Going Merry sails through the Grand Line when Luffy suddenly spots a glass bottle floating in the vast ocean. Inside is a map depicting a carnival island filled with flowers, treasure chests, and mudskippers! The letter accompanying the map reads: 'You are the lucky pirate chosen from one billion people on the Grand Line.' The paper emits a terrible stench that makes everyone nauseous, but Luffy’s eyes light up with an expression that says he must go on this adventure, no matter what stands in his way. When the Straw Hat crew finally reaches their destination, they find it to be a very ordinary island. Just as they begin to feel disappointed, a dazzling theme park appears before them accompanied by a majestic march, along with a pirate singing chorus whose members have leaves growing on their heads. Bursting out from the center of the theme park is an incredible man with a massive body and flowers growing on his shoulders—Baron Omatsuri. The Baron tells Luffy, 'I will grant you a mysterious treasure, but there is a condition...' This condition is to pass through the hellish trials proposed by the Baron. A hellish Carnival Island!? Completely swept away by the thrill of adventure, Luffy accepts the Baron's trials without hesitation... What exactly are the trials awaiting Luffy and his crew? And what is this so-called secret treasure?
