Summary:
Angered, Franky attacks and attempts to attack Kalifa for injuring Moza and Kiwi, but Blueno blocks his attack with Tekkai. However, Franky manages to pick Bluen up and overpowers him while yelling at Agent CP9. Blueno tries to use Shigan on Franky, but Rob Lucci stops him, saying they need Franky alive after they kicked Franky away. Usopp is surprised when Franky thinks what he did to upset Lucci and the others (he still thinks they are with Galley-La). Franky wants to know how CP9 found out about his hidden base, but Lucci says that’s irrelevant and says they’re there now and have an assigned operation. They then reveal to Franky that they are spies working for the World Government and surprise Franky by revealing his real name as “Cutty Flam”. Franky is impressed with their detective work, but is worried and wants to know where Iceburg is. Lucci says he’s dead to Franky’s shock. Lucci goes on to say that Tom confided the Pluton plans to Iceburg, who then confides in Franky and demands that Franky hand over the plans. Enraged, Franky fires a right hand at Lucca, who effortlessly dodges it and mercilessly knocks Franky backwards, sending him crashing through the wall. Usopp is shocked by what just happened and the crash reveals a secret room. Lucci is surprised to see this and Kalifa informs them that they are preparing the tables. Lucci confirms that this may be where the Pluton plans are and orders the other CP9 agents to find them. Blueno notices the labels that say “Cutty Flam”, “Iceburg” and “Tom” and Lucci walks over to the picture. Franky, back on his feet, tells Lucci not to touch him, that the picture is his memories and is where he grew up with Tom’s workers.
The long flashback begins with a younger Franky riding one of his Battle Frankies to Water 7. Franky turns to see a large Sea King chasing him, firing cannonballs at him. However, it has no effect, it only makes the beast angrier. The Sea King dives into the water, causing the Franks to hit land above the Iceburg. Iceburg yells at Franky, but soon runs away after seeing a large sea king attempting to attack him. Iceburg yells at Franky again that they should be working on ships and not some “toys”, but Franky yells that they aren’t toys, but his battleships Battle Frankies. They continue to argue until Tom picks up the ship and builds it together using sheer force. Tom is excited about his work, Yokozuna agrees, and Iceburg and Franky stare in shock. Tom and Yokozuna leave with Iceburg and Franky chasing after them. At Tom’s Workers, the group is eating and Tom asks about Franky’s latest Battle Franky model. Iceburg blasts Franky as his newest ship almost kills them both, but Franky yells at him. Tom could only laugh at that as Kokoro walked in and tried to calm them down. Kokoro then says that another ship carrying wood was attacked by pirates and that since the pirate king was executed, the entire town has been taken. He goes on to say that this is causing people to lose hope and that Aqua Laguna is preventing them from properly harvesting the wood. He fears that Water 7 will eventually sink into the ocean due to Aqua Laguna’s frequent hits. Franky remembers that Tom has built a large pirate ship before and asks if he could build it. However, Tom laughs, angering Franky, and Tom says that there is no such thing as a plan for a pirate ship, but the flag does. Later that night, Franky wonders what Tom is working on and Tom says that it is the hope for their island, then tells Franky to go to bed.
During the day, a large Judgment ship arrives in Water 7 and the people want to know why they are here. It turns out they are there for Tom and the marines start bringing him aboard the ship. Franky and Iceburg try to get to Tom, but are stopped by a couple of marines, but Tom assures them that he will be fine. On board the ship, Jorge watches the process and one of the men says that Tom was responsible for building the Oro Jackson: Gold Roger. He says that Tom was sentenced to be executed in Enies Lobby because of his involvement with Gold Roger and Franky is horrified to hear this. Jorge says building a ship isn’t a crime, but says he has to make an exception for the pirate king. Jorge then says that Tom is doomed and orders the marines to take him away. However, the Marines are unable to move Tom due to his size and strength, and Tom begins to talk about his new project. He says it will be a train that will run on the surface of the water and says he will help lift people’s spirits by building the Sea Train. The people and even Jorge are interested and Jorge tells the marines to let Tom stay and asks Tom to tell him more. Tom says the Sea Train is like a ship, but it pumps steam and runs on rails. He says it will transport people, goods and even ships to other islands and will not be affected by sea conditions. Two people complain that the Aqua Laguna will destroy the dorms and the Sea Kings will cause trouble as well. However, Tom says that the tracks will be submerged a bit under the water so they won’t be affected by the waves, and he even plans to add a special siren underwater to alert the fish when the Sea Train is approaching. He says it will even scare the Sea Kings into not bothering the Sea Train. He has plans to connect the tracks in multiple places much to people’s excitement and Tom says he will complete the plans very soon but says it will require a master shipwright to build it. Jorge says that the Sea Train will also go to Enies Lobby, which Tom confirms and says that the Sea Train will fill Water 7 with hope again. Jorge says how long it will take and Tom says it will take ten years to build. Jorge then tells Tom to build him and tells Tom that the next ten years will be considered a probationary period. The people are excited to hear the idea of the Sea Train, but Franky still looks worried.
Back at Tom’s Workers, Tom is happy to still be alive, but Kokoro is a little concerned that Tom was laughing, but is happy to hear about the Sea Train. Iceburg comments saying that the Sea Train is a great idea, but Franky suddenly gets up and teaches Yokozuna how to do a front crawl. Iceburg yells at Franky for leaving, but Franky is still upset about how the world government wants to execute Tom for all the work he’s done. Franky leaves and shows Yokozuna how to swim and Iceburg is still mad at him and even tells Tom that he should kick him out for the way he’s acting. Tom says he found Franky two years ago on Scrap Island shooting cannonballs and Franky says his parents tripped him. Tom says his parents were probably pirates who couldn’t handle his behavior. Tom says that he has a good heart and says that he and Iceburg will become shipmasters one day. Some scenes are shown with Tom showing the finished Iceburg plans and Yokozuna cheering. The three work on the raft while Franky watches them from afar. He builds more Battle Franks, but the others are more focused on building the Sea Train. Franky eventually starts helping out a lot, much to Tom’s delight. Franky, Tom, Iceburg, and Yokozuna face several obstacles during the construction (including being chased by Sea Kings and breaking the railing). Years later, people are still sulking until one person says that the Sea Train has been completed. People start boarding the Sea Train with Kokoro as a guide. The Sea Train successfully sets off much to the delight of the humans, Tom, Yokozuna, Iceburg and Franky. The sea train, Puffing Tom, officially gives Water 7 hope.
