About one week after the infamous clone carp incident, Chopper was once again perched on his little barrel with the tiny fishing rod in his hands, humming the latest of Brook's tunes as he carefully watched the bobber drift up and down in the gently sloshing waves. This time his regular fishing partner Usopp was also in attendance, sitting on the railing of the ship with one leg hanging lazily over the side, so Chopper didn't need to bother anyone else with having to supervise him. They were still moseying about in the same stretch of sea that the clone carp populated (according to Robin's investigation) and so they had memorized a photograph of the silvery fish to ensure that a harrowing incident such as Chopper's cloning did not happen again. No more clone carp sushi, nuh-uh, no way! He thought with a small chortle to himself.

"It's such a shame, though," Usopp sighed aloud suddenly, causing Chopper to look at him quizzically. The sniper gave the reindeer a contemplative look. "Just think how useful it would be to have more than one Zoro or Luffy, or even an army of you, Chopper!" The Zoan doctor was caught between being amazed that Usopp had read his mind and upset that Usopp had implied that an army of him equated to only two of the more beastly members of the Straw Hats. "I just wish we would've had more time to study it to see if we could use it," he sighed while tugging on his pole to entice something from the deep.

"Luffy would eat it before we even had a chance to do anything with it, and that would be much worse than an army of Choppers," Nami snorted as she walked by with a basket of aromatic, fresh tangerines; she knocked Usopp upside the head as she did, knocking him off balance and nearly sending him overboard.

"Watch it, Nami! You're lucky I don't have a Devil Fruit or I woulda drowned! Drowned, ya hear me?" Usopp shouted after her while shaking his fist. She just ignored him. "It doesn't matter much, anyway," he shrugged once her returned his attention to Chopper. "The odds of us catching another one of those clone carps is one in a million, probably."

"Yep. It's a clone carp," Robin confirmed as she looked from her encyclopedia of local fish species to the suffocating silver fish that was lying in a puddle of seawater on the deck. Usopp was crouched down next to it, jaw against the wooden deck with a disbelieving, drawn out "Whaaaaaaaaaaaaaaaaaaaaaaaaaat?" stuck in his throat. Chopper grabbed his horns and rapidly shook his head from side to side in dismay.

"We have to throw it overboard before Luffy eats it! We stopped in port and stocked up on apples just to be safe, but we all know he won't eat it!"

"Shhhh!" Usopp hissed and slapped his hand against Chopper's furry mouth with a shift gaze toward the front of the ship. Chopper had reeled in the fish without much fuss, so Luffy had not had the care to abandon his perch on the lion figurehead. Even now, he was still blissfully unaware of the discovery and was leaning into the wind with his tongue hanging out like some kind of slobbery hound. Chopper scrunched up his face in disgust when he saw blobs of spittle being carried away by the brisk breeze. "This is what I was talking about, Chopper! You're a doctor. You can study the cells and see if we can make them into some sort of weapon or tool!"

"I don't know, Usopp… I feel kinda bad… I mean, for their part, those clones had feelings too… I would hate to just create and destroy them at will," he murmured as he looked at his shiny reindeer hooves. Although at first he had been overjoyed that his crew cherished him and him only, but after he had really gotten to thinking about it, it wasn't fair to the clones to disregard their feelings and experiences, even if they were limited. Had they really been identical to Chopper after all, or was it only at the cellular level? What about their souls? "It doesn't feel right…"

"Well, Chopper, maybe by studying the interaction between the clone carp cells and the cyanide antidote, you can find a way to halt the cloning process without reverting the clones back to fish," Robin pointed out reassuringly. At such a suggestion, Chopper rubbed his chin thoughtfully while staring at the fish, whose eyes had glassed over and was presumably deceased.

"Hmm… That doesn't sound so bad!" With a contented hum, he flung the fish over his wee shoulder; because it was nearly as large as himself, it disbalanced him a bit and he had to wobble back and forth to get his bearing. After he finally righted himself, he exhaled confidently and gave Robin a toothy grin. "Robin, I'm sure you have books that'll be helpful; can I borrow them?" The dark-haired woman smiled sweetly and used her Devil Fruit powers to bring down helpful tomes from her voluminous collection, piling them into her arms.

"Shall we, Chopper?" came her wine-smooth voice. Chopper nodded eagerly and whirled on his hoof to totter off to his private study, with Robin walking languidly alongside him. She graciously opened the door for him and allowed him to enter before walking in after him. Chopper tossed the fish onto his work desk before clambering up into his spinning doctor's chair, rotating it before standing up in it to get a good look at his project. He prodded it a few times to make sure it was really dead, as he didn't want to needlessly make the fish suffer through the dissection process, before he retrieved his sharp tools from one of the shells.

"Okay! Let's begin, Robin!"

Chopper, with the aid from Robin, had been conducting his experimental medicinal research in secret for about one week with no progress. He had been sneaking ice from the freezer in Sanji's kitchen to keep the fileted fish meat on ice in his room until he had made enough cell plates to last him through his research. Once he had the brain cells cultured so that they could continue giving instructions to the body cells, he had set to his research. He had figured out how to get the clone carp cells to convert to his own cells by using some cheek swabs, but he hadn't figured out how to negate the clone toxin without killing the parent cells and making the other cells turn back to clone carp cells. With an agonized, frustrated groan, he slammed his forehead down against the desk, making all his tools and cell cultures and sample jump up from the force. "This is hopeless! I'm not getting anywhere, Robin! No matter how diluted we make it, the cyanide solution just keeps reverting the cells!" he wailed in distress. He looked up at her with tear-filled eyes, disappointed in himself.

"There's no need to fret, Chopper. Science isn't an easy process. None of the greatest scientific achievements have happened overnight!" she responded encouragingly from her seat on the bed. She had several of Chopper's medical textbooks spread out around her, and had been scanning the passages for useful biochemical or cellular physiology information that may have been relevant. His bottom lip stuck out in a pathetic pout. He was less than reassured. He slunk down from his office chair to scamper across the room and climb into Robin's lap and hug her midriff sadly. She laughed lightly as he buried her face into her belly, and she wrapped her arms around him in a motherly embrace.

"I'm a failure as a doctor."

"No, you aren't, Chopper. We all think you're a fabulous doctor. Think of how many times you've saved us from our wounds! The Straw Hats couldn't ask for a better doctor."

"Ah, shut up, you bastard~!" he giggled as her kind words finally seeped through his depressive aura to send a fluttery, blissful butterfly of joy flapping around in his little heart. He looked up at her with a grateful grin which she returned with a soft smile. He spun around to sit in her lap, feeling quite contented perched on her pillow-soft thighs, and picked up one of his toxicology textbooks to begin flipping through the pages. He then screamed and brought it close to his face, as if the passage that had caught his attention would be more significant if it were literally right in front of his eyes.

"What is it, Chopper?"

"How could I miss this? Of course! We shouldn't have been diluting the cyanide! We should've been converting it into a related but less toxic substance! Sulfanegen sodium; do I have any sulfanegen sodium?!" he screamed as he dropped the book and jumped off of Robin's lap. With how fast his little hooves were whirling, he probably ran on the air across the room to frantically clamber onto his desk and begin rifling through the various bottles shelved in his desk. Cyanide poisoning wasn't exactly something that pirates had to worry about, as it was mostly used in assassinations performed by elite bounty hunters (and the Navy, probably) but Chopper kept a stock of random antidotes to all kinds of things just in case. It had been a habit after his beloved mentor had perished thanks to his ignorant gift of a poisonous mushroom. Chopper knew much better now, but in the back of his mind he was always afraid that one of his beloved crew mates would suffer some kind of intoxication and he wouldn't have the antidote for it.

He squealed in glee when he found the labelled bottle reading "Sulfanegen Sodium." As he sat down on the desk, not even bothering to use the chair, Robin crossed the room to lean over and watch his experiment, hands on her knees. He drew up a small amount of the liquid into the dropper before transferring the little droplet to his current diluted cyanide solution, mixing the two together. He then took one of his cell plates and scooped up a bunch of them to re-plate them on a fresh media plate; they immediately adhered and began rapidly dividing, slowly spreading out in a circular fashion. Before they could fill the plate too quickly, he aliquoted a drop of his new solution and dropped it onto the cells. He awaited a reaction with bated breath. In all his trials previous, the parent cells would shudder and die, while the others changed color to a silvery hue which was indicative of their reversion to clone carp cells as a result of the toxin being negated by the small amount of cyanide from the crushed apple seed solution.

Instead of the aforementioned result, the cells quivered before their division slowly came to a stop and remained the salmon hue that was indicative of human (or in Chopper's case, human-reindeer) cells. Chopper crowed triumphantly and held the plate over his head as he did a happy jig. "Robin! I did it! I did it!"

"Yes, you did. I told you that you could do it!"

"Hey, what's with all the noise in here? You woke me up from my nap…" Came a sleepy third voice. Chopper turned around to see that Zoro had opened the door and was scratching his stomach while he stifled a yawn with the other hand.

"That's what you get for sleeping literally in front of his door," Nami chimed as she shoved him aside to poke her orange-haired head into the room. "What're you so excited for, Chopper?"

"Go on, Chopper. Why don't we tell the entire crew your monumental discovery?" Robin mused. Chopper nodded eagerly and hopped down from the desk to skip out of his study and out onto the main deck. It only took a short moment to assemble all the crew members, and soon they were all looking with expressions of confusion and interest at the little cell plate in his tiny hooves.

"Robin and I have been working with clone carp cells to see if we could find a way to stop their transformation without reverting them back to the fish!" he announced proudly. Sanji stopped his scientific revelation reveal with a startled gasp.

"Chopper, you what? But we agreed that the clone carp was bad news. We don't need two of Marimo or Captain Idiot!"

"Hey!" the two insulted parties chimed in irritated unison.

"Shut up; you know I'm right."

"Yeah…"

"I just felt bad about what we did to all my clones," Chopper admitted with a deep frown. He looked down at the plate of unassuming cells. "Sure, I'm the real Chopper, but all the other Choppers still had feelings, too! It makes me feel sad that we just disregarded that…"

"Are we really debating the morals of getting rid of clones produced by a dumb fish?" Nami asked uncomfortably, but from the look on her face, the moral dilemma was affecting her too. A discontented murmur rippled around the group.

"But with this new solution I made, we can stop anyone who eats the fish from dividing indefinitely! The host cells live in the main host and the other cells that are the clones communicate by quorum sensing to conduct their cellular operations!"

"What the hell does that mean?" Luffy asked while picking his nose. The scientific jargon was rapidly making him lose interest.

"The cells talk to each other," Robin clarified.

"Whoa! That's so cool!"

"Yep! The cyanide in the apple seeds killed the parent cells, which are slightly different genetically from the clone cells. It's not actually reproducing by budding, me and Robin figured out, but a very complex process in-between asexual and sexual reproduction! The daughter cells are the ones that are direct clones and produce identical cells." By the blank stares, he could tell that he was losing his audience. "A-anyway, with this solution I made, the parent cells don't die, but the toxin is destroyed and the daughter cells get a signal to stop dividing so fast, but instead probably undergo the cell cycle at the same speed as our cells do instead! That means that the division stops but the clones don't turn back into fish and are free to live their lives!" he finished with a big grin.

"Wow, Chopper. You're brilliant!" Nami praised while patting him happily on the head.

"I understood none of that but it sounds important, but good job! That's my doctor! Shishishishi!" Luffy laughed with his arms crossed. The rest of the crew similarly showered him in proud, appreciative remarks and Sanji even graced him with a celebratory cookie. He munched on it elatedly, careful that the crumbs didn't fall into his cell plate, while answering questions about the process. Sanji had forgiven him for stealing the ice since it was such important research.

"So, are we gonna test it or what?" Usopp asked suddenly. Chopper swallowed his last bite of cookie before looking uncertainly at the plate. Sure, it worked in cell-level trials, but an organism was complicated. Would it really work?

"I wanna eat it! I wanna it eat!" Luffy cried and shot towards Chopper's room to abscond with his frozen fish samples, but thankfully Zoro and Sanji were able to muscle him back. All it took was Robin telling him that two of him couldn't be Pirate King for him to consent to never, ever eating the clone carp. "I ain't competin' with me…" he grumble with his arms crossed as he sat cross-legged on the deck.

"I think Chopper should have the clones," Nami suggested, which threw the little reindeer for a loop.

"Huh? Why me?"

"Because you're our most important member, duh!" the navigator beamed brightly down at him. If a reindeer could blush, he would be. "You're always running yourself ragged trying to heal everyone at once. How many times have you wished there were more than one of you? When they aren't doing doctor things, they can do other things you like to do too, like helping me water my tangerines."

"-and helping me and Franky repair the ship and build new things! We always love your help, Chopper!"

"Yeah! It's superrrrrrr!" Franky agreed with Usopp, striking his signature pose with a flashy smile.

"I always enjoy you helping in the kitchen, too," Sanji mused while taking a drag from his cigarette.

"And you always make a good audience for my performances! Yohohohoho!"

"Imagine how many fish tons of you could reel in!" Luffy hollered with his fists in the air. "Meat all around!"

As they listed off the so many helpful things that Chopper did on a day-to-day basis, he began to sniffle and cry, so overwhelmed by their appreciation of him.

"Y-you guys… I love you so much!" he wailed and jump forward to hug the nearest pair of legs to him, which happened to be Sanji. Even though he was staining the cook's black pants with tears, he didn't seem to mind, only leaned over to loving rub the top of his head through his hat. "But… But… With all those other me's… Will I still be useful?"

"Of course," Robin smiled gently at him. He rubbed his eyes while looking up at her. "Those other Choppers will be like your brothers. They might know the same things at first, but in time, they'll evolve their own personalities and skills- but you'll still be our ship's doctor, and they can never replace you in that." A fresh wave of tears flooded his eyes and he buried his furry face into Sanji's legs again.

"Wahhhhhhh! I love you all so muuuuuuuch!"

And so, that's the story of how the Straw Hat crew sort of got bigger. The Chopper clones were an existence only known to the Straw Hats, as they were never taken along in the fighting (to protect them, as it turns out they couldn't actually use Chopper's Zoan powers like he thought they would be able to) and lived in the bowels of the ship, all seven of them occupying a cozy little bedroom that Franky had added on. Like Robin had said, they soon developed their own interests, styles, and personalities. Timmy Timmy Chopper was even shyer than Chopper was but took a liking to Robin, and loved it when she told him bedtime stories. Tommy Tommy Chopper was rambunctious and adventurous like Luffy, and if they had no hint of danger on islands they stopped at, the captain would tote him along; if there was danger, they always made sure to bring him back little unique gifts. Terry Terry Chopper had a culinary talent and Sanji made him his apprentice. Tama Tama Chopper had a penchant for gardening and looked after Nami's tangerine trees whenever they were gone and even has a little garden of his own growing flowers which they sold in port for income. The two they liked to call "the twins" because they were so alike, Tippy Tippy Chopper and Tappy Tappy Chopper, were little shipwrights in their own right and loved to help Franky go to work on the Sunny's never-ending repairs and improvements or test out Usopp's newest inventions. Tappy Tappy was a little different from his twin in that he was musically inclined; he enjoyed learning about it from Brook. Finally, there was Tavi Tavi Chopper, who was rough and gruff and looked up to Zoro like an idol. More than anything, though, they loved their big brother Tony Tony Chopper and always made sure of one thing…

That they all went fishing together, because it was what bonded them as siblings. Sometimes, Chopper wouldn't even sleep in his own bed but would slip down to where his brothers slept, and they would abandon their bunks to all dog-pile in a pallet on the floor. Every day after that, he was so glad he pulled that clone carp out of the sea, because his family just got that much bigger.
