''OnePiece 3D: Straw Hat Chase'' is the eleventh film in the long runnning anime and manga series, though many fans consider it more of a special than a film as it returned to the ShortAnimeMovie format (30 minutes) and was paired with a {{Toriko}} film in the summer of 2011. Regardless it is the first One Piece film to be made entirely in CGI.

The film begins with a old pirate, Schneider, and his dog, Buzz, walking the streets one night. Schneider has been coughing up blood lately and takes it as an indication the he's dying. He tries to part with Buzz not wanting his old friend to see him die but Buzz will not be shaken off easily.

Out on the seas, the Straw Hats are going about their journey when Luffy finds that his prized straw hat is missing, sending him into a frantic search around the ship. Unable to find it the crew assumed it fell into the ocean and search individually for it with the Soldier Dock System. Ussop and Chopper happen upon Schneider's ship, finding the weakened pirate inside. As they take him back to the Sunny Go to get healed. A eagle lands on the ship with Luffy's hat in it's mouth. Needless to say , once Luffy finds out he goes on the warpath to get it back, chasing the eagle through various landscapes and obstacles. But why does the eagle want the hat in first place and what does Schneider have to do with this?

!!''One Piece 3D: Straw Hat Chase'' has the following tropes:

* ThreeDMovie
* AllCGICartoon
* AttackOfTheFiftyFootWhatever: The climax sees the Straw Hats against three Marine giants.
* BreakHisHeartToSaveHim: Or rather "Break his heart so he doesn't watch me die" which is what Schneider tries to do with Buzz.
* TheFaceless: The Marine Giants all wear helmets over their faces.
* KickTheDog: The Marine Captain that captures Luffy [[spoiler: and Buzz]] does this by holding Luffy's straw hat by the barrel of his gun and then shoot it to just to mock Luffy.
* [[spoiler: MistakenForDying: What Schneider thought of himself when he started coughing up blood. Turns out he had a fork lodged in his stomach he accidentally ate that was poking his insides. He unknowingly coughs it up in the middle of the movie which Chopper finds shortly after.]]
* NoNameGiven: The Marine Captain.
* TheReveal: [[spoiler: Buzz is of course the eagle in question having eaten a eagle zoan model Devil Fruit.]]
* {{Ska}}: Also known for being the first movie that doesn't use the orchestral score, rather a Ska band was hired to preform the music. If it fits with the movie or not is up to the viewers
* SnipeHunt: [[spoiler: Schneider had told Buzz he can stay with him if he can steal the hat of Straw Hat Luffy, thinking it'll be an impossible task. Buzz pretty much proves him wrong.]]
* TheUnfought: The Marine Captain, though Luffy pays him back for the Kick The Dog moment by knocking a giant near the platform he's on. The pieces of mace the giant was holding shattering and crushing the captain as he was trying to run.
