One Piece 3D: Mugiwara Chase

Luffy wakes to a disaster no member of the Straw Hat crew can treat lightly: his treasured straw hat has vanished. With the one possession he values above all else missing, the entire crew joins a frantic search across the sea.

The trail leads to a strange bird that has taken the hat and refuses to make the chase easy. As the Thousand Sunny barrels after it, the pursuit collides with Marines and other obstacles, turning the recovery of one simple hat into a wild race worthy of the Straw Hats.
