Fit or Fat?

Chapter 6

Nami awoke to the sound of cheering. It seemed as if Luffy had seen the next island. Perfect! I'll be able to stock up on food again! she thought. She struggled through the door, again with the help of Robin, and saw the island. It was quite a big island, bigger than anything they had been to in a while.

They landed on a beach, which seemed OK for now. They weren't staying for long, just replenishing their supplies. However, before they could disperse into the town, they saw a terrible sight. The streets were lined on both sides by men in white and blue sailor outfits with caps on their heads and guns in their hands. Great, the Marines were here. It seemed as though this was a World Government owned island.

"Hey, look!" They'd been spotted! "It's the Straw Hat Pirates!"

"Wait, what? We're not trained for this!"

"Who cares? I wanna get promoted! We're sure to if we take these guys down!" The Marines charged at the Straw Hats and a fight began.

"Alright! Time to test my new strength!" shouted Nami excitedly. She was slow moving so she couldn't really get to any of them before the others took them. Out of nowhere, a Marine soldier flew towards her, probably knocked off his feet by Luffy or someone. He bounced straight into her belly and for a moment was completely lost in the folds, until he was flung back out, far away somewhere. This whole thing also knocked Nami back, mostly because of her bad balance, so she slooooowly tipped back and crashed to the ground, sending a massive shockwave all around and sending everyone else to the ground.

"Wow! I'm so strong!" cheered Nami, waving her fists around. She tried to pull herself up but that wasn't happening. It seemed her 'secret weapon' was single use. Crap. Now I just look stupid. Unfortunately, most of the Marines and pirates had got back up, and were continuing their fight.

"Uh... can somebody help? Please? I'm kinda stuck here!" Nami was quickly realising she was a rather large target and she didn't like the idea of that at all. Is it me, or am I just hungry? she wondered. Her strength had seemingly decreased. If I could just sneak over to a food store... She began formulating a plan. She managed, with a lot of effort, to roll onto her belly. She then proceeded to inch forwards with her hands pulling her. It took a while but she managed to escape the chaos and squeeze into a cake shop. It was empty, probably because everyone had heard that the Straw Hats were on the island. But that was OK. It just meant she didn't have to pay anybody. She then ate and munched and gobbled and wolfed down every last cake in the shop. She felt a boost of energy and walked heavily out the door, ready for business.

When Nami returned to the scene however, her friends had already beaten them down.

"Oi Nami!" cried Luffy smiling and waving. "There you are! We were about to go looking for you!"

"Where've you been?" asked Zoro suspiciously.

"Probably pigging out again." Usopp noticed the cake icing around Nami's mouth. It had also spilled down her neck, which was starting to lose definition.

"Oh, y'know, just strengthening myself for the battle. But it looks like you didn't leave me any." Nami frowned at them

"Don't blame this on us!" roared Zoro. "If you had just trained properly, you wouldn't have to 'strengthen yourself' every time you fell over!"

"This is kinda getting out of hand," agreed Usopp.

"You're just mad because you're so small!" retorted Nami.

"Let's go!" Luffy whined. He was getting bored of this argument.

"No way!" Nami shouted. "You guys got so caught up in that battle that you forgot why we came here! We were going shopping and I for one would still like to do so."

Luffy remembered. "I still have to buy meat!" He dashed off down a street, simply assuming there would be a butcher's in that direction.

"Well, whatever." said Nami, not expecting that sudden change. "I'm gonna go buy more food. See ya later!" And off she went, hoping to buy her own weight in food.

That evening, nobody saw Nami at dinner. They were confused by this but grateful for the time they had to have a meeting about their ever-growing navigator.

"So," Usopp led the meeting, enjoying his moment of authority. "What are we going to do about our big marshmallow? I'm not sure it's good for her, all this eating, even if it's not unhealthy. It's just... wrong."

"But she's funny and squishy!" laughed Chopper, no longer against the idea now he knew it wouldn't affect Nami's health.

"She's a person, Chopper, not a bean bag," Usopp scolded him, and Chopper became serious again.

"I just want Nami-san to become Nami-swan again..." Sanji was feeling very sorry for himself and they could tell as his cooking had always tasted a little off since it happened.

Brook was looking rather content with life. "Nami-san has been finding it very difficult to hide her panties recently. I don't see why that needs to change."

"Oi, Zoro!" Usopp called a sleeping Zoro and he awoke, yawning.

"What?"

"What do you think of Nami now?"

"She's too fat and she's deluded herself, thinking it's making her stronger."

"OK, brief but to the point, that's good..." mumbled Usopp. "What about you, Franky?"

"Ow! I think there is a fine line between being brave and being stupid. Nami is on that line. If she puts on too much weight, the line won't hold her, and she'll be in the stupid zone."

"What was that metaphor? That was awful! Anyway..." Usopp turned to the captain, and ultimately, the deciding vote. "Luffy, what do you think?"

"For now, it's fine. If she gets much bigger, she should be stopped. However, as it is now, there is no problem."

"But, Luffy-" began Usopp.

"No." Luffy was serious now. "Nami is our nakama. We have to accept her for who she is and we can't get in the way of her dreams. Anyway, I'm tired! Night, everyone!" They all walked out and over to the men's quarters, Robin leaving them to go to the women's quarters. Before they could part, however, they heard a sound that made their hair stand on end.

"Help..."

"Oh no, a GHOST!" shrieked Usopp.

"H-help, please..."

It seemed to be coming from the women's quarters. They crept towards it slowly, all eight of them assuming battle positions.

Slowly and carefully, Zoro twisted the handle. He pulled the door open and it creaked, making him shiver. The Straw Hats peered inside.

"Help me!" wailed Nami. "I can't get out!"

They all stared in disbelief. Nami was filling most of the room. Her cheeks were almost as big as her head, her neck had disappeared, replaced by three chins, her belly made up about 75% of her body and she was unable to stand on her legs which were tiny in comparison.

Not one Straw Hat still thought Nami's weight gain was a good idea. Not even Nami herself.

"Knew that would happen," Zoro and Usopp said simultaneously, almost looking triumphant.
