Paper Jimmy Neutron: The Thousand Year Door

Chapter 1: A Rogue Welcome

Author's Note: ...I am extremely surprised that nobody has done this fanfic yet.
Anyway, this fanfic has a very interesting story. I read this one Ed, Edd n Eddy and TTYD fanfic by legendofzeldarocks, and got inspired to write my own TTYD fanfic. I tried coming up with a few ideas, but I didn't really like any of them. However, when I found out that Nickelodeon had rejected a proposal for a Season 4 of Jimmy Neutron, I was very disappointed. I eventually decided I wanted to write a Jimmy Neutron crossover. I found that Jimmy Neutron fit the pace of TTYD, and that the characters went well together.

It actually took a while to figure out how Jimmy, Carl, and Sheen got to Rogueport. I came up with several iterations for the intro before settling on what you see in the story.
(In other words, it took a while to make an intro that worked.)

Disclaimer: I do not own Jimmy Neutron or Paper Mario: The Thousand Year Door. If I owned Jimmy Neutron, we'd still be having new episodes today.

It was a warm summer day. The weather was clear, and the sun was shining in the bright blue sky. Just yesterday, Jimmy Neutron and his best friends Carl Wheezer and Sheen Estevez had graduated Lindbergh Elementary.
"So, now that summer's here, what do you guys want to do?" Jimmy asked as he and his best friends Carl and Sheen walked down the sidewalk.
"Maybe we could go on a trip to South America to see some llamas," said Carl.
"Already did that during spring break."
"Let's go see the new Ultra Lord movie!" exclaimed Sheen.
"We already saw it last Saturday when it opened," said Jimmy. "And last Sunday as well."
"Then if we already did those, what will we do?"
"Hmm..." Jimmy thought for a moment. "Maybe we could hunt for some lost treasure..."

By some contrived coincidence, a letter floated down in front of them.
"And now the adventure begins," Sheen told Carl. "Some odd letter comes out of nowhere. I mean, what are the odds of that?"
"Jimmy..." Carl said apprehensively. "I really don't like the sound of this..."
Jimmy picked the letter up and looked at the address on the envelope. It was from Princess Peach, and it was addressed to Mario Mario on 85 Nintendo Street, PO Box 1889 in the Mushroom Kingdom. Nope, definitely not meant for anybody in Retroville.
"Hey, wait a minute..." Jimmy said when he was done looking at the address. "This isn't addressed to us!"
"Maybe we should return it to whoever it was addressed to," suggested Carl while Sheen grabbed the letter from Jimmy and scanned the address.
"These are fictional characters, Carl," said Sheen.
"Says the boy who claims Ultra Lord created the entire planet..." Carl then noticed a perfume smell coming from the letter and let out a sneeze. "And I'm allergic to perfume..."
"You're allergic to every single thing, Carl. I wouldn't be surprised if you were allergic to Ultra Lord."
"You know, since this physical letter somehow managed to make it into our hands," said Jimmy. "Either Mario is real, some other genius out there could have recreated these fictional characters by assembling them from carbon and H2O, or this is just simply a joke somebody pulled."
"Or maybe they were taken out of the video game, just like the reverse of that one time we put ourselves in Ultra Lord vs. Robo-Fiend!" Sheen suggested. "Oh, man, that was one of the best adventures we ever had!"
"You know what? It's worth a try to find this Mario. To the lab!"

When they got into the lab, Jimmy put the letter under his lab computer's scanner.
A fat Italian plumber with brown hair, a black mustache, a red hat with a matching shirt, and blue overalls appeared on the screen. They immediately realized that Mario was indeed real.
Jimmy put the letter on his workbench before he started furiously pounding keys to figure out how to get to the recipient's place.
"Hey Carl, you wanna peek inside this envelope?" Sheen asked Carl.
"Uhh... I'm not sure... Would this Mario like if we opened it?" Carl replied.
"Sheen, Carl, no! That might contain some very confidential information!" Jimmy said, turning to the two.
"Oh, don't worry, Jimmy, Mario won't mind!" Sheen opened the letter up anyway.

It read,
Hello there, Mario brothers!
I am now on holiday, traveling in the Mushroom Kingdom.
In my travels, I came into possession of a mystical map... A treasure map, actually.
It was sold in a box to me by an old merchant in a town called Rogueport.
But since it would be too difficult to try to go find treasure all by myself...
I thought you could help me hunt for it! You will, of course, won't you?
I've included the map with this letter, so please bring it with you when you come.
I'll meet you at Rogueport. (In other words, you MUST come!)
-Princess Peach Toadstool

"There's a map in this envelope? That's so cool!" Sheen exclaimed as he pulled said map out of the envelope. The map looked very aged and weathered. "Look at it, Carl! Maybe we'll be on a treasure hunt!"
He handed the map to Carl.
"Umm, Sheen, hate to burst your bubble, but there's no treasure marked on the map," replied Carl.
"Or maybe it's marked in invisible ink, so we hold it up to a light and reveal the treasure like I saw in all those detective movies! Surely Jimmy has a light somewhere!"
"I hope you guys are done snooping through the highly confidential contents of the envelope," Jimmy interrupted. "Because I've finally pinpointed the coordinates of the recipient's house. According to my calculations, it will take too long to go by hovercar, so I'll create a portal to get there. I'll also create a remote to return us home just in case we have to come back."

"Sorry Mario," said the turtle-esque mailman, a Paratroopa. "I lost your letter on the way here..."
He was sitting on Mario's doorstep with Mario and his other friends.
Among his other friends were a brown mushroom (a Goomba) with a blue cap, a pink bomb (a Bob-omb) with a braided ponytail for a fuse, a green ghost (a Boo) with ribbons, a purple fish (a Cheep-Cheep) with orange and white fins, a yellow spark of energy (a Lil' Sparky) with a pacifier, another turtle-like creature (a Koopa) with a blue shell and a red scarf, and yet another turtle (a Lakitu) riding in a cloud.
"It's alright, Parakarry," said Mario, comforting his friend. "You've been doing better lately. This is just a one-time mess up, after all."
Soon, Jimmy and his friends appeared out of a strange wormhole with Peach's letter. Mario and his eight friends gazed upon it in surprise and awe.
"I don't assume you lost this letter?" Jimmy asked, holding out the letter.
"The letter!" Parakarry gasped. "Thank you very much, umm..."
"Jimmy Neutron. It's a pleasure to help."
Jimmy shook Mario's hand and Parakarry's hand before giving the letter to them. He and his best friends watched as Mario read the letter out loud. After he was done reading it, he reached into the envelope, but the map wasn't there.
"Say, where is that map the Princess mentioned?" Mario asked.
The rest of his friends eyed Parakarry while Jimmy turned to Carl and Sheen.
"Carl. Sheen. Hand over the map," he demanded.
"Umm, we don't have it!" replied Carl.
"Then explain this!" Jimmy yanked the map out of Carl's grasp.
"The map!" everyone gasped as Jimmy handed the map to Mario.

"Hmm... Fascinating..." Mario said as he took a close look at the map. He looked up at the three boys. "Say, since you three found the letter, would you three like to come with me on my adventure?"
"Yes, please!" yelled Sheen.
"Umm, Sheen? What if he's a faker?"
"Well, who wouldn't want to come with him if they knew he was real?"
"Carl, Sheen," said Jimmy. "It's time to head home..."
"No way, Jimmy! This could be a once-in-a-lifetime opportunity! It's not as great as meeting Ultra Lord or Link would be, but it's better than nothing!"
"Alright, fine..."
"Mario, are you sure we should take these boys along with us?" asked Luigi, stepping outside before the green Boo scared him from behind. Luigi immediately pulled out his Poltergust 3000 out of fright.
"Come on, Luigi," said Mario. "You've got to have all the fun you can when you're still young!"
"Okay, I guess he's not a faker if he has Luigi with him," said Carl.
"Alright," said Luigi. "But we're gonna have to keep an eye out for them. Their parents wouldn't be happy if they got hurt..."
"We'll give you fifteen minutes to get ready," said Mario. "Then we'll have lunch before we head to Rogueport."

Jimmy, Carl, and Sheen went back to Retroville to get their things.
Jimmy packed his tools, pencil, notepad, and blueprint paper, Carl packed his inhaler and meds, and Sheen packed his Ultra Lord mask and recipe book. They put their belongings in Jimmy's Hyper Cube.
Each of the boys brought about ten dollars, as well as their favorite toys with them. Jimmy brought an Einstein action figure, Carl brought his llama figure, and of course, Sheen brought his Ultra Lord action figure. They also packed a few board games to play when they were bored.
Unfortunately, Jimmy's mom, Judy, was out walking Goddard, so they couldn't take him with them if they wanted to leave with Mario. It also meant that Jimmy could not say goodbye to his mom before he left. On the other hand, Carl and Sheen did get to say goodbye to their parents.
Once they were done packing, they noticed that they had only one minute left. They rushed to Jimmy's lab and headed through the portal, but they forgot the remote in their haste.

"Alrighty, is everybody all-a-set?" Mario asked everybody.
"Yeah!" everybody else exclaimed.
"Great! Let's-a go!" Mario jumped up. "To the Toad Town harbor! But first..."

On their way to the harbor, Mario introduced his friends to the three boys and treated them to a nice pizza lunch cooked by Tayce T., the town's cook. After that, he got the boys' dollars converted into Coins. A Coin was worth about two quarters, so they each got 20 coins.
"Gee, Toad Town seems more peaceful since we last beat Bowser," the Goomba with the blue cap said as they walked to the harbor.
"Well, if they have anybody to thank, it has to be us," grinned the green Boo.
"Oh, Bow, you and your snobby ways," said the pink Bob-omb.
"Come on, come on," Mario told the two. "We don't want another argument going on again."
"It's best not to sour the mood," added the purple Cheep-Cheep. "We've got three boys going with us on an exciting adventure! We wouldn't want to kill their joy, now, would we?"

Soon they got to the docks, where a small boat was about to arrive.
"Well, looks like we're here," said Luigi. "Can Bow not scare me when we're on our way?"
"Why, hello there, Mario!" the captain of the ship said when he arrived. "Princess Peach told me you were going on a trip to Rogueport to meet her, no?"
"Why, of course! I'm-a ready to go when you are!"
"Well, then, we're off!"

A few hours and some rough weather later, all thirteen of the passengers were fast asleep when the captain called them.
"Alright, everybody, it's time to wake up!" he called. "The town of Rogueport is straight ahead of us! Look!"
"We're here now?" exclaimed Sheen. He was the first to wake up, which wasn't a big surprise considering his hyperactive nature. "Oh, cool!"
Gradually, one by one, everybody else except Mario woke up.
"Hey, bro," said Luigi. "It's Rogueport!"
"W-Wha?" Mario asked when his brother woke him up.
"We'll arrive shortly," said the captain. "Please prepare to disembark."
Minutes later, they arrived at the Rogueport docks. The captain apologized for the delay from the rough weather and wished them a good trip before he departed.

"Ho ho! Master Mario! Who are these fine chaps you have with you?" a voice called.
An aged humanoid with a mushroom cap, a Toad, approached the gang.
"Hey, Toadsworth! This is Jimmy," Mario explained to the Toad. "And his best friends Carl and Sheen."
"Greetings, Jimmy. Greetings, Carl. Greetings, Sheen," Toadsworth said, shaking the hands of the three boys. "What brings you jolly chaps here?"
Mario explained everything that happened that led them here.
"Mmhmm... Princess Peach sent you a letter and a treasure map? Oh! I just remembered! She told me to wait for you here before she went to take a stroll through this wretched little burg, and when she didn't come back, I started fearing for her safety!"
"Typical Toadsworth," Luigi told the kids.
"But now that you're here, Mario," Toadsworth continued. "I am very sure we'll be able to find her. But alas, I know my place, Master Mario, and I cannot come with you. It's all up to you, sir."
"Me?" Mario asked. The three boys were fast asleep.
"Yes. You've rescued her countless times before, and surely you're up to the task again."
"Oh, yes!"
"Now if you need me, I will be at the inn relaxing with a spot of tea, perhaps. Just drop on INN! Ho ho!"
Mario tapped the three boys on their shoulders to wake them up. They went up the stairs to the town square.

"Mario and I will be following Toadsworth," Jimmy told his friends when they got there. "You guys can walk around the town if you'd like."
Toadsworth headed towards a hotel-esque building. The words above the door said in bold words, "Podley's Place."
When they got inside, they could hear an odd sailor named Flavio was chanting to a red skull-shaped gem of some sort. Jimmy rolled his eyes at him before he and Mario continued to follow Toadsworth.
"Jimmy! It's terrible! A Bandit robbed me while Sheen and I were walking!" Carl cried, running into the building.
"It's called Rogueport. What did you expect?" replied Jimmy as they continued following Mario and Toadsworth. "And what happened to Sheen?"
"Yeah, about that..."

"Hey, you!" called Sheen as he chased the Bandit. "Come back with my friend's money!"
"You aren't catching me, sucker!"
Sheen chased the Bandit to the back alley where it lived.
The door was immediately locked before Sheen could reach it.
Sheen kicked the door until the Bandit finally cracked.
"Alright! I'll give you your friend's money back if you stop kicking my door!" he snapped.
"Gee, that was easy," said Sheen. "All I have to do to get pilfered items back is to kick the thief's door until-"
The door slammed on Sheen's hand.

"So, what's your rate?" Jimmy asked the Toad in charge of the inn upstairs.
"Five coins per person for one night," smiled the Toad in charge of the inn.
"Five times thirteen... That's sixty-five coins."
"Wow, you did that all in your head?"
"Well, I am a boy genius..."
"I'll pay sixty of the coins," Mario offered. "For myself, my brother, and our friends."
"And I'll pay the fifteen for myself and my two friends," said Jimmy.
"Thank you!"

"Hello? Jimmy? Carl? Where are you guys anyway?" Sheen called. After he confronted the Bandit, he started looking for his best friends. He ran into somebody searching for something right outside her house.
"Hey, you! Don't move!" the house's owner yelled. Her name was Zess T., and she was a very grumpy Toad with an apron.
"Why not?" asked the dumbfounded Sheen.
"Some doofus just bumped into me and made me lose a contact lens! Now don't you move while I look for it!"
"Okay..." Sheen waited for a few minutes before he said something. "Can I move now?"
"No!"
"Hey, there's Sheen!" Carl pointed to Sheen as soon as he and Jimmy left the inn to find him.
"Hey, guys!" Sheen called. He ran to them, accidentally stepping on Zess T.'s contacts in the process. "I got Carl's money back!"
"You did?" Carl gasped.
"Yeah! All I had to do was heckle the thief until he broke down."
The three boys went back into the inn while Zess T. clenched her fists at Sheen.

After dinner, Jimmy, Carl, and Sheen were in their room with Toadsworth while Mario, Luigi, and their friends hung out at Podley's soda bar downstairs.
"Jim? What are you working on?" Carl asked his best friend.
"It's a self-defense device I call the Neutron Phaser. Rogueport, being a wretched hive of scum and villainy, is a dangerous place with all the criminals running around, so I invented this to protect us."
"Isn't this dangerous?"
"It's strong enough to keep us safe, but not dangerous enough to kill. Plus, it has a safety switch, so it won't work unless you pull it down. Still, it's not a toy."
"Hey, cool, a wooden hammer!" Sheen pointed at Mario's hammer.
"Sheen, don't touch that! You could hurt somebody with it!"

"A letter for Mario Mario!" a voice called. "It's from the trouble center!"
A crow-esque creature, or a Craw, named Gus walked up to Mario and handed him the letter. The letter was from Princess Daisy in Sarasaland. However, it did not say who it was addressed to. Maybe Gus assumed it was for Mario?
"Crikey! So soon?" Mario asked. "Luigi, take a look at the letter inside!"
He handed the letter to Luigi.
"Something isn't right here, but I know it's definitely Daisy's handwriting..." said Luigi, looking at the letter. "Oh, no, she's been kidnapped!"
"If she's been kidnapped, we'd better do something!"
"But what are we going to do with the map?"
"Hmm... That's a good question... While I am worried about the boys' safety, they seem to be excited AND able to handle things all on their own..."
Mario walked up to their inn room.
"Children," Mario addressed the three boys. "Would you three like to take our place in this treasure hunt?"
"I don't know, it's a lot of pressure-" Carl began.
"We're in!" Jimmy and Sheen cut in.
"Okay, then, take good care of this map. The princess has entrusted us with the map, and now we are entrusting you with it."
Mario handed the map over to Jimmy.
"And take these two spare hammers. We have our own. However, one of you will have to get a weapon yourself."
"Of course Jimmy made his own weapon already," Sheen whispered to Carl.
"It was a pleasure to meet you, Jimmy Neutron, boy genius," Mario said before he left the inn at precisely 10:13 PM. Toadsworth fainted, uncertain of the fate of the princess since Mario had other things on his hands.
"You owe grandpa a hammer," the mushroom with the blue cap told Mario as they left. "One of those was his favorite!"
"Um, Jim, how are we going to survive this adventure without Mario?"
"We'll probably figure it out tomorrow," yawned Jimmy. "But for now, it's time to go to bed. Night guys..."
"Night, Jimmy," Carl and Sheen replied.

Okay, so the reason I wrote Mario out of the story was that most of the PM crossovers featured him starring alongside the crossover characters, and so I could make the adventure harder. I also wanted to focus on Jimmy, Carl, and Sheen, and their interactions with the partners in the game.
I also wrote Goddard out for similar reasons.
(Trust me, the adventure would be too easy if I kept them both in)

And don't worry about Goombella, she'll appear in the next chapter!
