Finn had just finished signing an autograph for an eager fan from the breakfast kingdom when Jake's voice began to buzz through the small earphone concealed under his hat.

"Foxtrot...Indigo...uh Nancy? Finn, do we really have to do this."

"Yes, Jam...Alpha...Kilo...oh glob... fine no more code names." Finn had suggested code names to make the experience feel more math, as he described it. "What's up Jake? Any assassination attempts to report? Maybe a sword fight that needs fighting?" Finn asked hoping for a situation that would require his certain talents. "Anyway, what's the prob homie?"

"Do you think it's a 'make your own ice cream stand', or just bowls of different types?"

"Jake, for glob's sake, your only supposed to call about problems."

"Yeah, well so far nothings happened, so this dog is thinking of a nice bowl of vanilla with double sprinkles."

"Jake, stay focused or I'll make sure there's no ice cream left." Finn warned.

"Fine, uh...The groom's parents look pretty bored, find a way to entertain them, I guess." Finn couldn't hear the rest, but could make out something along the lines of, "If I don't get some floppin icecream..."

Finn rolled his eyes as he headed round the plaza, pushing through the huge crowd of guests, heading toward the castle where the newly weds currently were. Occasionally he would hear muffled voices accompanied by pointing. "Oh my glob. It's Finn!" or "Look! It's Finn the Hero!"

Suddenly a pair of hands grabbed Finn on the shoulders causing him to jump and instinctively reach for his sword, until he realised it was a group of party bears that were dragging him toward the stage where the karaoke was set up.

"Jake! They want me to sing. I can't sing to this many people." Finn harshly whispered through the mic.

Jake, currently seated in the surveillance room, let out a hearty and unhelpful laugh, and replied through the mic. "Knock em dead pal!"

Jake heard the door open behind him revealing Princess Bubblegum, who had changed out of her finest evening attire, into her lab coat.

"Finn, I gotta go for a minute, Peebs is here." Not waiting for a reply, he turned off the earpieces sound, ignoring the monitors which showed Finn being, no longer dragged, but carried toward the stage.

"What's up Bubblegum?" Jake asked casually.

"Jake, I've got it! She actually gave it too me." She replied gleefully, showing a device shaped like a hoover.

Jake, being a dog, had a natural hate for hoovers. He found himself growling at the device, suspicious of the loud noise that could from it at any time.

PB, realising her mistake, assured the agitated canine. "This isn't what it looks like. This is a nuclear protunding reverter?

"Protunding?" Jake asked cautiously as he eyed the hoover, still suspicious of the device.

"It's a word I just made up, sounds catchy doesn't it." PB said proudly.

"What does it do?"

"I don't want to have to explain it twice, get Finn to come here immediately."

Jake realised that he had forgotten about his best friend, leaving him to the mercy of the crowd. Turning to the monitor, he saw the crowd raving.

'Is that a good or bad sign', Jake thought to himself. Turning on the microphone, he could hear Finn's signing and the crowd chanting and clapping in the background.

"Damn, he's pretty good" Jake muttered to himself.


"So let me get this straight, all it does is store nuclear waste. Seems pretty pointless, you know, cause it's called nuclear waste and junk..." Jake trailed off.

The trio, Finn, Jake and Princess Bubble Gum were currently in the lab at the top of the castle. The music from the celebration could still be heard pretty clearly, even from this distance.

"It doesn't just store it, the device reverts it to it's natural state."

Finn and Jake stared blankly at PB waiting for her to go on.

"If we could get a sample from the great mushroom bomb, we could revert it and create the super gamma isotope. Because everyone in OOO is mutated due to the fallout from this isotope, except you Finn, we could solve nearly every problem that the people of OOO have."

"Like what?" Finn asked, slightly worried that his days of helping people could be over, if everyone's problem were solved by this device.

"Well it would allow me to cure diseases, purify food and environments, heal wounds instantly, solve genetic issues, as well as possibilities that I haven't even calculated." PB listed, blissfully waving the device around in her hand as she imagined the possibility.

"Uh, PB sorry to spoil your fun but the Great mushroom bomb detonated in a different land, on like the other side of the earth."

"That's was what I was just about to-"

"Woah, woah, Woah! No way. There is no way are we going to accept this quest. It would take months, maybe years!" While Jake stood firmly by his statement, Finn looked slightly indecisive. He was torn between staying in OOO and doing his regular hero duties, or going on the biggest quest of his life.

"This wasn't actually my project. As you two may know, technically I am not eighteen but-"

"Over 400 years old." Finished Finn.

Jake smacked Finn over the back off the head as a small reminder not to remind women of their age.

"Look, this project wasn't started by me. It was created by your father, Joshua." Hearing his name immediately caught Finn's attention.

"I have put a lot of research into this and I discovered that an unknown being put an enormous ward around the entire crater, where the nuclear waste from the great mushroom bomb currently is. This barrier was put up to prevent anyone from going near the crater. The ward is powered by two large gems of power which are near to the crater." PB then produced a small crystal key from a safe she had hid. "Your Dad found this in an ancient ruin before he disappeared. Until now, I couldn't figure out what it was for, but then I did a little cross referencing" PB paused for a dramatic effect of sorts. "This key disables the ward around the crater."

There was a long pause after PB finished. Both the heroes were awestruck by their Father's hidden legacy.

"Why is it so important now, why can't we do it some time later?" Jake asked.

"I uh...need it soon, because...not only will it help our citizens but it is necessary for stabilising...the Earth." PB blurted out rather quickly. "Look, I need you two. I'm sorry I used you for this wedding just to get this device, but now you have the chance to save the world."

Eventually, Finn relented, accepting the most dangerous quest of his life. "So, what do we have to do?"

"Well, you have to find the Cartographer, and get directions to the Great Crater from him. But he won't tell you unless you give him a rare eclipse stone, and I believe that the nearest one to here would be Nyptcorg Caverns."

"Okay, Nyptcorg Caverns it is...where is that?"

PB looked slightly ashamed. "Well, I had a map leading to it... but I lost the top half. So head to the Battler's kingdom, which is here..."Pb said pointing to a kingdom just below the tear in the map. "While your there, ask for directions to Nuskcrown. The people of Nuskcrown will probably know the rest of the way."

"Once there, you disable both the wards, grab a sample from the nuclear waste. Re-activate the wards, then come home."

After PB finished summarising the plan, she showed them how to operate the nuclear device that was imperative to the cause.

"So PB, who gave you this? Earlier you were saying 'she' gave it too you." PB looked up to see the yellow dog eyeing her curiously.

"The bride, and she gave it to me as a thank you for hosting the wedding here." The pink princess tried to sound as nonchalant as possible, avoiding eye contact with Finn and Jake.

Eventually, after all the details of the arduous quest ahead of them was finalised, they gathered all the necessary equipment from PB and headed for the door. As they headed for the door, Finn felt an arm on his shoulder.

"Guys, no one can know about this quest. If anyone ask, Just say you are going away for a long time. The device your carrying can be turned into a devastating weapon, so no one can know about any of this."


Finn and Jake walked down the steps of the Candy Castle, heading toward the draw bridge. They had to get home as soon as possible.

Most of the guests had dispersed from the town centre, either moving to a different area or they had gone home. Party Pat was playing some soft relaxing music now as the night dragged on.

PB's orders had been to rush home, grab your gear and set off immediately. There was no time to waste.

Jake looked at his best friend, seeing the worry etched into his face. "Bro, are you sure about this? We'll be gone for so long." Jakes main concern was leaving Lady Rainicorn behind, but he was also highly anxious of leaving OOO, the continent that will always be home to him.

"Jake, this is our chance to become the best heroes we can be. Not only will we save OOO, but we will save the Earth." Jake watched Finn speak with such passion and enthusiasm, he couldn't help but feel it rub off on him a little. During their little conversation, Jake saw a certain someone over Finn's shoulder.

"Before we go, you might want to have a quick word with her." Jake said, pointing to the flame elemental nearby.

The Flame Princess had seen the two of them walking down the street, and was mentally scolding herself trying to think of something to say to them. She took a quick glance at Finn and Jake, to see them looking right back at her. Jake gave Finn a quick pat on the back as he jogged off toward the drawbridge.

"Hey, Flame Princess. Uh...How are you?" Finn asked awkwardly, avoiding eye contact as he rubbed his arm. The fiery queen was basically mirroring his movements."

"Good!" She replied, slowly examining the human boy.

Finn took a quick moment to examine the infatuation of his mind. He couldn't tell if she had actually changed physically since they last met, but too him she looked twice as beautiful then before.

The flaming girl noticed the perturbed attitude of the boy, and softly asked. "What's wrong Finn?"

"Listen, FP...or FQ...uh..FK? I'm going away for a long time...so I guess bye" The knotting feeling in Finn's stomach was killing him as he saw the shocked look on the girl's face.

"What do you mean?"

"Jake and I are going on a quest that will take a few months, maybe a year." The girl's flame that had brightened originally at the sight of the boy, took a sudden dimming at the news. She heard herself choke up and stutter at her next question. "When...do you leave?"

"Right now-" He was cut off by the tight embrace of the ruler of the fire kingdom. He wanted to say so much to her, like how much he missed her. It was no secret after all. While most of the slime kingdom has heard his song for her, they misinterpreted the meaning. Only Jake really understood his dilemma. To love someone you could never be with. He wanted to tell her so much, but it was for the best if he kept his words to himself.

And here he stood, about to leave OOO for an unknown amount of time. Currently ensnared in a hug by a girl who owned his heart.

Eventually she pulled away, feeling embarrassed by her actions. She was the leader of a kingdom now, as much as she hated it, she didn't have time to even consider a relationship.

There was no was no easy solution. All she knew was that Finn was leaving now for a long period of time. She whispered quietly to him "Stay safe." Then turned and left, in an attempt to cover her outburst. Leaving Finn standing there dumbfounded but instilled with a certain confidence.


"Swords?" Jake asked, reading through his check list of equipment.

"Check" Finn replied, brandishing the demon sword. A katana hilt was also visible from the back of his backpack.

"Spare clothes?"

"Check"

"Lot's of food?"

"Check."

"Nuclear thingy?"

"yup."

"Map?"

"Got it"

"Crystal key?"

"Yep."

"Alright, let's go!" Jake exclaimed, ready to start his epic quest with his brother.

"Wait a second" Finn said hastily, running up the ladder to the attic. Jake could hear boxes being pushed out of the way. After a couple of seconds, Finn jumped down. "Right, let's go!"

Leaving the tree house, they turned around to take one last good look at the tree house. The last look they would have for a very long time. This moment marked the start of their quest, the beginning of a legendary journey.

Finn turned to Jake, a small grin on his face. "You know what time it is?"

"Woah! That's my line. I say that." Jake said, feigning anger.

After Jake finished drinking in the scene, he turned to Finn. "You know what time it is?!"

"It's ADVENTURE TIME." They shouted together, hi-fiving in mid air. After a small silence, they looked around the quiet hills where they lived.

"So you...uh wanna go now?" Jake asked.

As they walked toward their first challenge, Finn decided to spark up a conversation. "Just found out my tux is fire proof. Pretty cool, huh?"

It didn't take a genius to figure out how he discovered that, and Jake already had a sly grin on his face. "Already back at Tier one I see." He chuckled, seeing the small blush form on Finn's face.

"Don't worry bro, as they say, Distance makes the heart grow fonder. By the time we come back, you'll skip straight to tier 7."
