One Piece Movie 6 - Baron Omatsuri and The Secret Island

Sailing in the Grand Line, Luffy and his friends find a message in a bottle for an island resort, and they decide to take a vacation there. 

When they reach the island, they meet a man who calls himself Baron Omatsuri. Before they can start their vacation, the Baron makes Luffy and his crew take the Trial of Hell, which turns out to be a strange version of goldfish catching and a game of ring toss played on boats.

Luffy's team manages to win both of them, but in the meantime, each of them begins to notice something odd about the island.
