Summary:
Luffy, Zoro, Usopp, and Robin are standing near the dead dragon that Zoro killed, and Luffy is trying to pull out the man stuck in the dragon’s body. Luffy succeeds by taking out only the legs, so everyone thinks he killed the man. However, the legs are alive and they run and try to find the Shichibukai. Luffy runs after him and clings to his legs after his legs fall on top of him.
Elsewhere, the Straw Hats, who have been captured by humans in protective suits (Sanji, Nami, Chopper, and Franky), are in a prison cell marked CHECK-102 and have been shown to a gassy figure known as “The Master” who is very interested. in Franconia. A few minutes later, he wakes up in his cell, trying to figure out how to get out. He then sees a man’s head that has been cut into pieces and put back together. The head is alive and tells them that his body was dismembered by the Shichibukai and he feels ashamed that he wasn’t killed after being dismembered.
Back with Luffy’s group, Usopp sees a harpy on top of a burned building, but after yelling for everyone to look, they suddenly disappear. They then approach the lake that separates the fire and ice halves of Punk Hazard. Luffy befriends a centaur who thought Luffy was one of his kind. The Punk Hazard people who work for the Master see Luffy’s group and tell the harpies about them.
Luffy, Zoro, Usopp, and Robin are standing near the dead dragon that Zoro killed, and Luffy is trying to pull out the man stuck in the dragon’s body. Luffy only manages to pull out his legs, so everyone thinks he killed the man. The legs are revealed to be alive, so the whole group stares. Robin points out that there is no sign of an upper body, while Usopp states that he is quite tall. While the crew remains confused, the legs begin to attack them, but they immediately flee to the unknown Shichibukai. Luffy is then seen calling out to join his crew, causing Usopp to headbutt him and tell him to drop it. Luffy runs after him and lunges to his feet, crashing into him and both falling.
The group grills and eats dragon meat. Luffy asks Usopp what someone is called “like this” and Usopp replies that it’s a centaur. It turns out that a pair of legs are now glued to Luffy. Before he can do anything else, the legs pick Luffy up and slam him into the ground. Usopp tells Luffy that his upper body must be having problems somewhere, but Luffy questions where Usopp’s sense of adventure is before stating that the legs were born that way. He asks what the legs are called when it kicks him again. Zoro calls out to the others from the top of the building. He points and the crew realizes that they are standing right in front of a lake with an ice covered mountain range beyond. Usopp and Robin realize that the distress call they received came from the cold side of the island. Luffy is excited about this and wants to eat the ice shard. While yelling at Zoro (who wants to explore the island with Luffy with Robin), Usopp senses something strange on a nearby chimney. He looks to see a smiling winged woman staring at him and she then flies away like a bird. Usopp tells the others about what he saw, but he himself isn’t sure.
At the lab, a guard walks in to inform the master that he has kidnapped Sanji, Nami, Franky and Chopper and the master is very pleased, especially with Franky’s cyborg body and later decides to experiment on them as he tells his men to lock them up. room. Back on the Sunny, Brook, left behind because they believed he was already dead, wakes up while some guards are still on the ship. He asks if the guards know where Nami and the others are, but the guards are too shocked and shoot him.
Later, Franky wakes up to Sanji kicking the wall and asks what’s going on. Nami tells him it should be obvious and Chopper tells him they’re locked. Franky tries to remember the last thing he did, and Nami assumes that whoever took them must have hit them with sleeping gas, which Sanji confirms. Franky then wonders where Brook is, Nami replies that she doesn’t know. Chopper says that if the abductees are humans, then the skeletons are not needed. Franky tells Chopper that he isn’t human either and Sanji retorts that neither is Franky. From one corner, a voice asks them if they like puzzles. The group looks around for the source of the voice and Chopper jumps in shock. The voice comes from the mouth, which is one of the eight pieces of the dismembered male head. The man asks if they could put him together. Each member gives it a go and ends up getting pretty close, just tangling their hair and beards, but admitting their gratitude regardless. Chopper asks him why he’s alive and the head says he doesn’t know because he thought he was dead when someone cut him up and claims he feels ashamed for what happened.
Back at Luffy’s group, everyone except Usopp plans to go to the cold side, wondering how they will cross the lake. Usopp is pessimistic about surviving until then and wonders how Luffy can stay in good spirits. Luffy is attacked from behind but manages to dodge. The attacker is a centaur with leopard feet, and once they realize what they have in common, they become instant friends. He apologizes to Luffy for mistaking him for an intruder. Zoro and Usopp notice that he has made another strange friend.
Another person is watching over them and counting the numbers. Den Den Mushi rings and the bird woman Usopp saw earlier asks if the intruders have been found. The person answers in the affirmative and states that they are going to kill him. Birdwoman happily flies on the cold side of Punk Hazard.
