Hello. This is Jess, and this is my first fanfiction.

I've been having a hard time chosing what type of fanfiction to write and for what show or book and, well, what better for a newbie than Adventure Time?

Thanks for taking your time to read this and, hope you enjoy.

Disclaimers: All characters and almost all elements of the story belong to Pendleton Ward and Cartoon Network.

It was just another ordinary day for an human boy and his yellow dog:

That is, if your dog can stretch and manipulate his body in many mind-blowing ways and you get to slay giant monsters everyday.

Such was the predicament Finn and Jake were in. After half an hour, they still couldn't bring down the ferocious monster.

Something was wrong, terribly wrong. Finn and jake should've been done slaying it by now and be back at the treehouse. Finn's demon sword had no affect on the beast, leaving only slashes on its steely skin.

It wasn't until Jake tied thick vines around the monster's feet that the monster tripped face-first and the duo was given a couple of moments to take it easy.

"This ain't cool, Finn," Jake said as he dashed besides his human brother, who was trying to figure out the monster's vital spot. "We're going to miss out on BMO's sausage ice cream recipe! Let's just go." He inspected his sides. "Besides, I think I broke a few ribs… "

"Gross, dude," breathed Finn. He watches as the monster snapped out of its brief blackout and proceeded to rip apart the vines that made it vulnerable. "And we're not going to bail! Heroes have to stick until the end!"And with that, he charged straight for the rising monster, frantically waving his trusty sword above him as he yelled out a primal call of sorts. "Yaaaaaaaaaahhhhhhh!"

Jake rolled his eyes. He didn't have time for this. Sausage ice cream was awaiting him. But still…

He stole a glance at Finn, and noticed how serious he was about saving the day. No matter how many times the monster swatted him aside, Finn would get up and try again, bruises and sword and all…

"Humph. Fine." He let out a groan and ran up to the determined Finn.

However, after having been messed with for more than a couple of times, the monster was in a more foul mood. And deadly intentions were reflected on its butt-ugly face.

Jake noticed a strange sound coming from the monster. "What's it doing?" The monster repeatedly moved its mouth from side to side and made gargling noises, as if it were using a whole bottle of monster-sized mouthwash.

"I have no idea."

The monster's mouth mechanism slowly expanded at a ninety-degree angle. A bright light could be seen from within the monster's jaw. The light intensified by the second, and seemed to be directed straight towards Finn and Jake...

Finn was the first to make sense of what was going on. "Oh Glob."

But before Finn and jake could react and before the monster could unleash its atomic acid upon the adventurers, a fire ball darted out of nowhere and landed right in its single eye. Finn was sure the whole land of Ooo could hear the pain-stricken howl coming from the great monster. The welcomed distraction gave Jake the chance to wrap his body around the monster and hold it in place as Finn delivered the final blows from.

Jake caught Finn in midair and slowly diminished to his normal size.

"That was rad, dude!"

Finn chuckled. "Couldn't have done it without ya, man."

Just then, Jake took note of someone interesting and his eyes widened, getting a gleeful glint in them. He extended until he was approximately Finn's height and whispered eagerly into his bro's ear. "Speaking of people you should be thanking…" He pointed behind Finn.

Finn blinked, and turned around. He said the only thing a surprised and not-so-great-with-greetings guy could say: "FP."

"Hey, Finn." Standing there, beautiful and radiant as always, was his girlfriend of seven months: Flame Princess. He didn't know how he missed her presence with her being so ablaze and, Glob, did he felt stupid.

"H-How did you get here?"

She approached him, leaving a small trail of flames behind her. "Not from your hat, that's for sure."

Finn immediately took off his hat and inspected the interior of it. Last time he checked, the bear he skinned was dead and totally not evil like Little Dude was.

Flame Princess laughed. "Silly. I watched you and Jake pass by my house and thought it'd be fun to see where you were going without me and, well, here I am." She spread her arms at her side, letting a few bright sparks escape from the tips of her fingers.

Finn scratched the back of his neck, blushing. "Shucks. I'm sorry. I…sort of forgot to invite you." He gestured to the 16-foot beast laying in the middle of the forest clearing. "This bad boy was jeopardizing the forest folk's home and they needed us here as soon as possible."

Finn turned red when he thought about the fire ball that enabled him and Jake to bring down the monster. "We'd be toast by now, if it weren't for you. Literally. Thanks"

"No prob. You're my boyfriend. It's my duty to protect you."

This drew a small chuckle from Finn. "Hey, I'm the hero."

Flame Princess crossed her arms. "Oh yeah? I clearly remember saving you from big sack of bones the first time we went to a dungeon."

Finn preferred not to think about that day. Flame Princess had gone bonkers that day, burning everything and anything in sight. However, she wanted to prove to herself that she was good- once and for all- and that was what made her stand out in his eyes. "You're so rad."

"Heh. Thanks, FTH." Just when she was about to reach for his hand, Finn stopped her. "Just a sec. I'm forgetting something." He rummaged through his backpack until he found what he was looking for. Standing back, he revealed a silver gauntlet and slid his left fingers into the unfilled tips. He offered his shielded hand to the princess.

"Milady."

She laughed; did she suddenly turn into a medieval princess? It sure felt like it. She wasted no time in intertwining her fingers with his now armored ones. Black colored eyes met with deep blue ones. "My knight."

They laughed together and walked into the forest, hand in hand. Deciding that they felt somewhat old-fashioned today, they attempted to speak in a Middle Ages style. Finn carried out the first try by turning to Jake and saying "Come hither so we may dine on sassages!" Flame Princess found it impossible to breathe after that.

Jake shook his head at the wandering young couple. "Ah. Silly kids." Then he registered what Finn tried to say to him. "Sausages? As in Sausage ice cream? Wait for me, guys!"

Meanwhile, In the Candy Kingdom….

Princess Bubblegum hadn't slept for many days by now. And, as most of the Candy People knew, this was never a good thing.

Peppermint Butler kept this in mind as he dared to enter the basement door which stated "Keep away" and walked down the concrete staircases that led to the many underground labs beneath the Candy Kingdom castle. He hadn't seen his princess for a while and he was worried. He had to make sure she received her occasional serving of candy biomass.

Glob knows him and the Candy People could not afford to lose their beloved monarch- Especially Peppermint Butler. No one else knew about his previous involvements with the underworlds, which included Death and not to mention Hunson Abadeer, and he was sure no one would accept him like Princess Bubblegum did.

He knocked on the first door he saw down the long corridor. "My lady?"

"Hey Peppermint Butler….Come in, come in…It's open…." responded a hoarse voice.

He peeked into the main lab and found himself looking at a messy-haired and unkept Princess. "Princess? Are you well?"

"Oh yeah. Just dandy…" Judging from the messy files overflowing her desk and the creepy smile she usually presented when utterly exhausted, Princess Bubblegum had been hard at work on something science-related. And she was not dandy.

Peppermint Butler took care not to step on the papers spread over the floor as he approached her. "Princess, I suggest you get some sleep immediately. You seem to be slightly out of your mind at the moment."

The Princess winced not at the butler's negative comment, but at the thought of getting some rest even though she still needed…. She shook her head in a zombie-like manner. "Have…to…finish."

"Finish what?"

She stood up and gestured for the peppermint man to follow her. "Follow…me…"

The Peppermint Butler had no choice to set the candy biomass drink on her desk, and trail after his unwholesome princess.

She explained herself as they walked across even more corridors. "We are running out of candy materials, as you are well aware of…." Peppermint Butler nodded at this, thinking of the limited supply of candy biomass he has to offer to the Princess. "And they will only keep on lessening as time flies by…"

"But what are you to do about this?" He asked.

Princess Bubblegum held up a finger. "That…is a good question." And with that, she pushed a secret button hidden somewhere at a concrete dead-end and they stood back as the wall lifted to reveal a never-before seen room filled with gadgets and many tiny TV-screens that decorated each wall of the room.

Peppermint Butler nearly jumped when the door closed shut behind them. When he turned around, he saw the princess sitting down in front of the extensive TV-Screens. She was patting a chair, motioning for him to join her.

"The forest folk gave me their permission to carry out my first experiment there…." She continued as Peppermint Butler finally managed to settle himself in the tall chair. She pointed at a top-left screen which displayed a complex machine in the middle of a clearing. "They agreed to stay sheltered while I conduct the experiment. No one should be near it by now."

"What will it do, Princess?" Peppermint Butler asked.

"Since we are….running out of supplies, I figured it would benefit us if we…tried to extract those necessary supplies from a dimension most similar to ours. For now, this machine should travel in that dimension and find any living being close by….and then transport it to us immediately along with itself. We should get…say…a simple forest creature as a result…" She smiled at her brilliant plan.

"So, we're going to become invaders?" Peppermint Butler was well-informed in the world's ancient history and the consequences of certain actions, and he knew Princess Bubblegum was, too.

"Yes, except…we're not going to kill or….spread diseases," She confirmed. "I plan for our involvement in that universe to go…unnoticed."

"And will it work?"

"There's only one way to find out…." She gazed at her clock and lifted the corners of her mouth into an eerie smile. "Ten more minutes to go before we test this bad boy out…."

It was Peppermint Butler's turn to wince. We?

So, how was it?

Heh. Yeah, not nearly as serious nor deep as Lin's (Snowflakes) on my wrists, but I try. And my title's not nearly as good as his. (Darn him.) But yeah.

This is Jess, and Reviews or Favs are much appreciated.~
