The episode begins from where the Rocket Man first took off inside Water 7 and up to rushing the Aqua Laguna wave.
The Franky Family prepare to fire canons at the wave.
Nami gets a call on the Den Den Mushi Sanji left her. She had it kept between her breasts.
the Marine forces on the Puffing Tom find that the World Government agents in the last two cars were completely defeated.
The opening theme starts.
Captain T-Bone wonders through the car on the train and notices one of his men shown an injury. It's just an irritated bug bite. T-Bone rips his cape and gives the shred to him so he can bandage himself. Though he's a kind person, his face is terrifying.
A Marine bursts in to report about the status of the forces in the last two cars.
Sanji is calling Nami from atop the Puffing Tom. Little is actually said.
Back at the Rocket Man, none of the cannons fire name any impact on the approaching waves. Inside, Nami explains Robin' actions to Sanji.
Luffy and Zoro move to the front to take care of the wave. They prepare to fire their shot. Luffy asks Zoro what one hundred eight equals when times by two. Zoro answers two hundred sixteen (ni-hyaku ju roku). That name is too long so they settle on three hundred.
They combine the attacks of Gum-Gum Cannon with San-Hyaku Pound Cannon. They combined their cannon attacks into one and broke a hole in the wave, creating a tunnel to pass through.
Back inside, Nami connects them with Sanji. They talk, and Luffy gives them permission to go as crazy as they would like.
Sanji breaks the receiver of the Den Den Mushi, but Franky had something to say to Luffy. Eiichiro Oda was asked with breaking that part hurt the Den Den Mushi. He said they are born like regular snails and those objects are attached. It didn't hurt the creature.
Usopp heard what has been going on since he left. Sanji and Franky are ready to move forward to rescue Robin, but Usopp backs out. He says it doesn't concern him. He walks off, but they are on a train in the sea.
Inside, T-Bone has ripped off so much of his cape there is hardly any left.
We see hints of other World Government officials.The train id being heavily searched. They finally search toe roof and find Sanji and Franky. The Marine is hit with one of Usopp's star attacks and falls into the water. They look back to see Usopp is now wearing an elaborate festival mask and cape. He's calling himself Sogeking.
