"Imagine all the crazy things I'll be able to do after finishing this."
Nathan sat on a tree stump just outside the forest. After leaving the Ice Kingdom he immediately began reading it. The first chapter was about discipline and ninja's mentality and philosophy. It was kinda boring but he figured it was probably important so it wouldn't hurt to memorize it. The second chapter was where it started getting interesting, filled with spells, ninja tricks, powers. It would take forever to learn it all.
"I can't wait to see Finn and Jake for real! Do I hug them? No, that'd be weird. They don't know me yet so I'd just be a huggy weirdo to them."
He started towards their house, after quickly looking through the book he found a section on disguises. He didn't want ANYONE to find out he was a human. Using the disguise spell his skin turned a very light green and he grew two small clear ice horns on his head. As he was getting bored walking he heard a voice behind him as Ethan appeared.
"Hey man."
"Ethan, hi."
Nathan often talked to himself when he was alone or just bored. It got to the point where he could talk with him like a different person so Nathan just gave up and gave him a name.
"So what do you wanna do now?"
"I dunno." said Nathan "Go see Finn and Jake, rule a kingdom, hang out with Marceline..."
"Wait, what was that last one?"
"Hang out with Marceline?"
"No before that, did you say rule a kingdom?"
"Yeah."
"How?!"
"I dunno."
Ethan shook his head. "I don't get you."
The clearing of the forest disappeared and the infamous tree house of the two heroes showed up. Nervously approaching the door he knocked loudly but there was no response.
"Hello? Hello? Guess no one's home." He looked at his watch, it read 3:59. "Well, I guess I have time to do something before it gets dark."
Ethan looked nervous.
"What is it?"
"I just feel...like something bad is supposed to happen soon. Something I'm forgetting..."
"Me too, what is it?"
As soon as the clock struck four, two pairs of hands burst from the ground. Nathan yelled in surprise and looked on in shock as a shark wielding a sword and a cat in a science coat came out of the ground and shook the dirt off of themselves.
"Ohhhhhhh...That's right, doesn't Finn kill these guys everyday?"
The shark and the cat approached menacingly.
"Uh, hey guys can we talk this out? Whoa!"
He jumped back as the shark swing his sword at him.
"I guess not."
The shark ran forward swinging, Nathan stepped back with each swing trying to stay out of range. Though he realized them if he just kept running he'd soon be tired. The shark, aiming at his face swung horizontally. Keeping his feet from moving Nathan swayed his top half back, dodging the blow while keeping his distance. He grabbed the shark's sword hand and attempted to take the blade but the shark was surprisingly strong. They both struggled with the sword until the shark lurched forward biting almost taking his face off as Nathan just barely ducked in time. Temporarily stunned by the thought of being devoured the shark punched him with one of his fins and managed to pull the weapon back to itself. Nathan stumbled back gritting hit teeth. A shark's skin was the equivalent of sandpaper so his cheek was now pink and bleeding. Realizing he had forgotten the cat he turned to try and find his other enemy only to be hit right between the eyes with a potion turning him into a lemur.
"W-what?! I'm furry?!"
He looked up to see the shark and the cat running at him. Acting quickly he scurried up a tree with the cat following him and the shark hacking the front of the tree to bring it down.
*Okay calm down.* thought Nathan. *If I remember right the potions don't last that long.*
With Science cat gaining on him he backed away while on a thin branch, the cat stalked him, readying to pounce when the tree suddenly wobbled and started making creaking sounds. Realizing the tree was gonna fall, he desperately jumped off the branch landing on the grass while the tree came crashing down. He panted, nearly having died a second time.
"How does Finn do this EVERY DAY?!"
With a poof he was back to normal.
"Alright then, MY TURN. Dagger of chilled glass."
He watched in excitement as magical ice grew in his hand and shaped itself into a dagger. Running at the shark he struck with an overhead strike but the shark blocked the attack and swung at his waist. Kicking off the ground Nathan jumped out of reach. He knew he couldn't beat the shark's sword with a dagger but that wasn't the plan. Nathan went on the defensive, pretending to be distracted by the shark while keeping an eye on the cat. Thinking it was an opportune time, the feline pulled out a vial from his belt and chucked it at him. Whirling around, Nathan managed to catch the potion in his hand, throwing at the shark and running at him. The aquatic attacker blocked the potion with his sword which turned the sword into a skunk. Surprised he dropped his former blade as Nathan ran the ice blade through the shark's stomach and pulled it horizontally across it's body. The shark fell with a dull thud and he turned his attention to the other enemy.
"Don't think you're getting away after what you did."
The scientist pulled out a potion, but instead of throwing it he drank the potion instead turning into a butterfly and trying to leave. Nathan ran forward and swatted the butterfly. After it was over Nathan collapsed on the cool grass in relief.
"Well...I suppose things could have gone worse for my second life and death struggle. I'd forgotten how dangerous Ooo could be."
He lay there a moment catching his breath when he heard footsteps. He quickly turned around to face them and his mouth opened in shock when he saw Finn and Jake looking at him.
"Jake who is that?"
"I don't know, you tell me."
" No I mean I don't know who he is that's why I asked."
"Yeah that makes sense."
The two heroes approached and took in their surroundings
"Dang it Jake, we missed fighting these guys because you took your time in the Grocery Kingdom."
"I don't remember you complaining when you were scarfing down those donuts we bought there."
Nathan stood there unsure of what to say.
"Um...hi?"
Finn turned to him. "You did all of this?"
"Yeah..." "Ha ha sweet. You seem like a pretty tough guy, we should fight sometime."
"Fight YOU? No thanks, I don't plan on fighting you...yet."
"Come on." said Jake I'll get you patched up."
They opened the tree house door and Nathan eagerly stepped inside feeling butterflies, as one would expect the floor was littered with treasure. Gold, jewels, weapons, it made up a good deal of the floor. Nathan fell backwards on the gold intending to make a snow angel, but got the wind knocked out of him as he fell onto the shiny metal.
"You okay?"
"Y-yeah...I'll be fine..." he said hoarsely, shakily getting to his feet.
Jake put a pad on his bleeding cheek and taped it down.
"So, horned guy." said Finn. "Where did you learn how to fight?"
"You can just call me Nathan. Anyway when I was a kid I would go on a bunch of little 'wars' with my friends. Large sticks were swords or could be bows if we found the right things. We'd fight all afternoon, get yelled at for coming home with bruises and the next day do it all over again." he chuckled. "Won most of those fights too."
"That's cool." said Jake. "Anyway we only came back here for those two you fought, and to pick up our pickled rock for this dungeon we need it in."
"Can I come?"
Jake's eyes lit up. "Yeah! That'd be perfect!"
"What?!" said Finn.
Finn walked up to Jake.
"Excuse us for a second."
He grabbed Jake's face and stretched it outside leaving Nathan awkwardly sitting at the table with his body.
"Jake, are you sure this is a good idea?"
"Yeah sure, why not he seems nice enough."
"Well I dunno I was kinda hoping to have some more bro time with you on this. We never go to dungeon very often."
"Finn? Good, sweet, innocent lovable Finn?"
"Yes?" said Finn whose eye had gotten bigger with every complement.
"I don't like going into dungeons."
"But dungeons are cool and awesome!"
"Nooooo!" whined Jake. Every time it's the same. You go crazy fighting monsters and I keep falling for the traps and get poked in the buns all the time. I only go cuz I'm worried about you knucklehead."
"Soooo...you'll come with me?"
Jake sighed. "Okay fine...but not this time! That other guy goes so I don't have to."
"Deal."
They returned to the house where Nathan was talking to BMO with a huge grin.
"And then what happened?"
"Then man-beast was beaten and everyone was happy."
"Ha ha, wow BMO you're amazing. Oh hey, you're back."
"Yeah." said Jake. "You can go."
"No!" said BMO clinging to Nathan's leg. "I still have so many more stories to tell. I didn't even get to Freddy the lonely kite."
"Don't worry, I'll listen to them okay?"
"Okay." said BMO still sulking a little.
Leaving the tree house Nathan picked up the dead shark's sword. I was heavier then he thought it would be but it was better than daggers. They had been walking a bit when Nathan spoke up to break the silence.
"So your name is Finn." he said, pretending to not have already known. "How many dungeons have you been in?"
"Dude, like a lot. I've been in tons of dungeons and seen all kinds of cool things."
"Any tips?"
"React to everything, it usually keeps you safe."
Nathan and Finn happily chatted along the way. Talking about the kingdoms, swords, and a bunch of other things, though Nathan had to be careful how much he knew about Finn. Eventually they reached a big wall with a goblin waiting for them.
"You got the rock?" asked the goblin excitedly.
Finn handed over the pickled rock and the goblin danced around with it. Still enjoying himself the goblin snapped his fingers and the wall split open to reveal the dungeon. Finn started in but stopped when he noticed Nathan lingering around the entrance.
"Hey you coming?"
"Yeah, give me a second."
He took a deep breath. *Okay you can do this. Just stay with Finn and you'll be fine.* Mustering his courage he followed Finn into the dungeon reaching a long hallway filled with empty suits of armor on both sides.
"Forget this." said Nathan you just KNOW something's gonna happen."
"Yeah...but it seems a little too obvious, keep your eyes open for traps."
Finn and Nathan started knocking over the suits of armor prepared for an attack but nothing happened. They had knocked over half of them over with no response.
"Huh, guess it wasn't a trap."
Nathan sheathed his sword and turned away when one of the suits of armor not struck started glowing with red eyes under the helmet raising it's ax.
"Hey, look out!"
Finn pushed Nathan away and stopped the attack. Nathan stumbled back and his a panel under his foot lowered as he stepped on it. *A trap!* he thought. He didn't have time to react as the ground opened up and he fell into a black pit.
