One Piece: Ocean's Dream!

One Piece: Ocean's Dream is a role-playing video game released for the PlayStation console. It was developed by 8ing and Q Entertainment, published by Bandai Namco, and released in May 2003.

Several years after its release, the game received a (loose) anime adaptation popularly known as the Ocean's Dream Arc, as well as a handheld remake known as Dragon Dream!

Plot
One day, while battling a rival pirate crew, the Straw Hat Pirates encounter a strange boy with a seahorse-like instrument. The sound of this instrument instantly knocks all of the Straw Hats unconscious; when they awake, they find themselves - along with the Going Merry - on an uncharted island, with no memories of who they are, what they do, or even how they fight.

Beset by enemies from all sides, the Straw Hats must accept the help of an old enemy-turned-friend in order to survive, solve the mystery of the island, and retrieve their memories.
