One Piece: Episode of Merry - Mou Hitori no Nakama no Monogatari

While sailing aboard the Thousand Sunny, Brook becomes curious about the small vessel called Mini Merry II. His question leads Usopp and Chopper to remember the Straw Hats' first ship, the Going Merry, and the long road that turned a simple vessel into a beloved member of the crew.

The memories return to Water 7, where the Merry's worsening condition tears Luffy and Usopp apart just as Robin disappears with CP9. To reunite their scattered family, the Straw Hats challenge the World Government at Enies Lobby, carrying with them the bond they forged with the ship that had crossed so many seas by their side.
