If you loved One Piece: Episode of Chopper Plus: Bloom in the Winter, Miracle Cherry Blossom, try One Piece: Clockwork Island Adventure
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.

One Piece: Episode of Chopper Plus: Bloom in the Winter, Miracle Cherry Blossom

One Piece: Clockwork Island Adventure
What they share
Both films are directed by Junji Shimizu, and they both carry the playful mood tag, and they sit in Action / Adventure / Animation territory. If that's the register that drew you to One Piece: Episode of Chopper Plus: Bloom in the Winter, Miracle Cherry Blossom, the second film will land in a comparable space — through a different lens.
What One Piece: Clockwork Island Adventure is
You chill on a beach with the Straw Hats, enjoying downtime. But the Going Merry gets snatched; Luffy's treasured hat goes, too. They're both nabbed by the Trump Pirates. Director Junji Shimizu knows the value of scarcity; this entry runs lean at just an hour long.
