Chapter 4

~X~

After the panties had calm down Luffy had barged in, his nose flaring with steam. "Where is the underwear?" he shouted, scanning the room left and right.

Nami just punched him in the head. "Calm down, they are laying on the floor over there, Chopper can you do something with them?" she asked, crouching down next to Robin, touching her forehead. "Robin?"

Chopper rushed right into the room when Nami spoke and he stopped short at the red panties. He gulped and gently picked them up using tweezers and slid them into a box quickly closing the lid. "There!" he said handing the box to Brook.

Book looked down at the box in his hand and he screamed, tossing it to Usopp who quickly tossed it to Luffy. Luffy grabbed it with one hand and looked at it. "Nami can I rip it appear for hurting my Nakama?" he asked, glaring at the box.

"No! Just put the box down and leave the panties alone until we figure out what to do! For now we need to worry about these guys!" she said, pointing to Robin.

"Ah! They need a doctor!" Chopper said, running back and forth with worry. Usopp stopped him by lightly smacking him on the head. "You're the doctor."

"Oh! Right!" Chopper said and ran over to Zoro. He bent down besides the swordsman and opened his little doctor bag. It wasn't long before he started checking Zoro, looking at his head, heartbeat and breathing. "Well Zoro appears to be okay, maybe a bump on the head but…, will they wake up?"

Nami frowned, biting down her lower lip. "I don't know. We'll have to ask that woman who sold us the costumes," she said and stood to her feet. "Chopper, Luffy put these guys somewhere besides the floor. Usopp, Brook you two are coming with me!"

"Ah but Nami why can't I come with you? I want an adventure!" whined Luffy.

"He has a point Nami, if something goes wrong Luffy might be the only one to stop it," said Usopp trying to help Chopper lift Franky off Sanji. They rolled the large man with great effort, rolling him to the side and so he was lying on his back.

Nami nodded. "Fine, you have a point. Luffy and Brook can come with me and you stay with Chopper and these guys," She said, waving a hand. "Put those panties somewhere hidden until we find out what happened. Come on guys lets go!"

"YOSH!" Luffy shouted hopping on his feet and running after Nami, laughing the whole way.

Brook followed after Luffy yohohoing the whole way.

Nami led Luffy and Brook through the town quickly finding her way to the old costume shop. She often had to stop Luffy from running off for food, but once they got there she stopped and stared at an empty lot. Frowning she tapped a "witch" on the shoulder and asked the woman what happened to the little shop that was there earlier.

"Huh? Girly there hasn't been a costume shop there in over 100 years. If you want to look up the island's history check out the local book store down the road," she said kindly, and pointed in the direction they needed to go.

"Thank you," Nami said and sighed. "This is getting way to weird, Luffy, Brook lets go," she grabbed Luffy by the back of his shirt and dragged him along the way to the book store. They needed some information and quickly. I hope Robin wakes up; she might be the only one to tell us what is going on if I can't.

Meanwhile back at the ship, Usopp and Chopper had managed to get Zoro, Sanji, Robin, and Franky all down to the men's cabin and into some beds. It wasn't easy getting Franky down there giving how heavy he was, but soon enough they managed, and the two were worn out. Now the two sat down on the middle of the floor, back to back and trying to catch their breaths.

"Remind me to tell Franky he needs to lose some weight," Usopp said, lying down on the hard wood floor, body screeched out.

"Yeah, good idea," Chopper said, doing the same thing. They both inhaled deeply and letting out a small breath of air, relaxing.

A small moment of silence passed by when they heard Robin groan, and quickly Usopp and Chopper sat up to see what was going on. "Robin?" they said together, standing to their feet and running over to the woman.

Robin slowly sat up and placed a hand to her forehead, rubbing at it gently. "Why do I feel so dizzy?" she said, eyes tightly closed.

"Robin, hang on I'll get you something to help with that!" Chopper said and he quickly rushed out of the room.

Usopp was about to ask Robin something when noticed Sanji sit up and look down at his hands as if he was confused.

"Oh! Sanji, how do you feel?" Usopp asked and ran over to the blond.

Sanji blinked and turned his head, looking at Usopp a deep frown. "Well…, other than a bit dizzy and that I am not Cook-san, I feel fine."

Usopp blinked confusion written all over his face as he pointed to Sanji. He then laughed, thinking it was a joke. "You must be dizzy Sanji! Why wouldn't you be our cook?" he asked, eyebrow raised.

Sanji however just frowned at Usopp.

Usopp went to say something else when he noticed Zoro waking up now. "Zoro?"

"What?" Robin asked from the other hammock, now opening his eyes.

Usopp's eyes widened when Robin answered and he pointed at her. "Oi lay back down you can't be well."

"What's wrong with Nico Robin?" asked Zoro, turning to look at Usopp a worried look rushing over his face. He then rubbed his stomach. "I think I need some cola I don't feel right."

"Franky?" asked Sanji, turning his attention to 'Zoro' now.

"Yeah Curly-cook?"

"Robin! I got some medicine for your dizziness," Chopper said as he ran into the room, holding a glass of water and a small pill bottle.

Usopp was looking left and right very confused of what was going on. Sanji had called Zoro Franky and Robin had answered when he asked for Zoro. He wasn't sure what it was, but something didn't seem right. "Chopper…, something isn't right here."

Chopper turned to Usopp his head tilted still handing the medicine and glass of water to Robin.

"Why do I have black hair?" Robin then asked, pulling on the black strands with a frown. 'She' then looked on down and her eyes widened when 'she' seen a pair of large breast. "Oi Oi which one of you are messing with me?"

Chopper yelped and jumped back from Robin, looking at her as if she went nuts. "Robin what's the matter?"

"Robin? Why are you calling me Robin? Where are my swords?"

"Zoro?" Usopp and Chopper said together.

"What is with all the shouting?" Franky said as he sat up.

Zoro turned to the blue haired man and his eyes widened. "Hey! What are you doing with my body?"

Franky blinked, getting off the bed and he turned to "Zoro" with a frown. "Oi I thought we agreed to keep that between us?"

"Cook-san," 'Sanji' said in a clam voice, getting the man's attention.

'Franky' turned his attention to Robin and blinked when he seen himself staring back at him. "Sanji?"

Sanji shook 'her' head. "It's me Robin."

'Franky' blinked and looked on down at his body seeing the bare legs and the Hawaiian shirt and his eyes rolled to the back of his head and once more he passed out hitting the floor with a loud thud.

"Franky… Sanji…!" Chopper yelped, handing "Zoro" the pills and water and ran over to the now cyborg-cook. Everything seemed to be very confusing. Something told him they had to figure out what was going on quickly before there were any more confusion.

~X~

"Usopp, Chopper!" Nami called out as she returned with Luffy and Brook a large book in her hands. She gave Brook the large book and told him to put it on the galley table while she went to check on the others and she told Luffy to retrieve the box that held the panties. Both men quickly went to do their jobs.

Nami quickly made her way to the boy's cabin and knocked on the door. "Usopp, Chopper?" she asked and opened the door.

When she stepped inside the room the first thing she noticed was that everyone was awake and standing in a cercal surrounded by Usopp who was drawing with a black marker on large pieces of paper. She then noticed that Sanji wore Robin's wanted poster on his back.

"Hey… what's going on?"

"Hang on Nami and I'll tell you in a minute," Usopp said, handing Robin the last piece of paper. Nami noticed that a purple string was attached to it and she blinked in confusion when the woman put it over her head. "Okay everyone introduce yourselves!"

"Nami-san I am horribly sorry you have to see me like this, your beloved Sanji!" said "Franky", his back turned to Nami as if he was ashamed.

"Robin" chuckled and she stepped up. "Hello Navigator-san, I'm Robin."

"Zoro" waved a hand to Nami grinning. "It's SUPER Franky!"

"Robin" folded her arms over her chest and glared at the orange haired woman. "Zoro."

Nami's eyes widened with shock as she took a good look at each of them. They had changed and were now wearing name-tags around their neck, and their wanted posters on their back. It was a very odd sight to see, and she never thought she would see Franky in suit or Zoro in Speedo, Robin in baggy pants and a t-shirt. Though she was glad Robin had stayed in pants and a normal button down shirt, even if it would be enjoyable to see Sanji wearing a mini dress.

"Yep…, nothing can get weirder then this," Nami said and she turned away from them all, wondering how to explain this to Luffy.

TO BE CONTINUED…

A/N: Zoro is in Robin's body, Sanji is in Franky's, Robin is in Sanji's and Franky is in Zoro's.
