TREEHOUSE 7:14 PM

Jake the Dog was sitting frustrated at a table. He was mumbling about Finn and how he changed. His elbows were propped up on the table, making his palms carry his face. The dog was so frustrated, he didn't notice the shadowy figure emerge from under the table. The figure quickly jumped at Jake with a loud roar, spit and rancid breath covered Jake's face. The figure was terrifying. It had a mouth about the size of Jake's face with sharp, yellow teeth, six soul-piercing eyes, long messy black hair, and bloody pig snout.

Jake glanced at the figure with no fear at all. Just sadness. "Oh.. Hey, Marceline."

The figure quickly transformed into a more recognizable person. "UGH!" The teen- vamp says, "That's the third time this week you don't even flinch! What's goin' on?"

"Ahh! It's Finn! He left again!"

"Again? Wow, he really has been leaving you out of the Adventuring stuff."

"Look.." Jake picks up a wrinkly piece of paper and hands it to Marceline for her to read it.

Frum Finn

I left. Bye!

Marceline looks at Jake. "That's not how you write a letter... or anything."

Jake groans, "Why is he being like this!?"

"Maybe it has something to do with that Fire Chick?"

Jake looks down. "Yeah... you're probably right."

Marceline has never seen Jake this sad. She comes up with something to say that will cheer him up. "Hey! Uhm.. His adventures must be so boring and lame without you!"

"Why's that?"

Marceline starts to stammer her words. "W-Well you're fast! Very strong! And just make things easier with your stretch-biz! I'm sure he's regretting ever leaving."

MYSTERY MOUNTAIN DUNGEON 7:20 PM

Finn dashes through a big, closing door, leaving the fire-breathing-hydra behind. He has burn marks, cuts, bruises, and the top of his hat is burned off. Leaving only the collar.

"WHOO!" Finn jumps with glee. "In your faaaaace! (Sigh) I'm having so much fun. Huh?"

Finn sees some stairs leading up to a pedestal holding a clear bubble with a bouncing, pink cube inside. Finn, seeing no reason to keep his hat anymore, rips it off and drops it on the floor. He then starts to walk up the stairs to the pedestal to the pedestal. He sees that the sides of all the stairs, and the pedestal look like they have some kind of runes. He also sees that everything else is dark, even the walls. All he was able to see was the stairs and pedestal. He comes up to the pedestal and inspects it.

"Hmm. What is this?" Finn sticks his hand in the bubble. "Huh. Feels like... jello." he stares at the cube that's bouncing intensely inside the bubble. He times his grab and catches it. The cube starts to try to break free from Finn's grasp. Finn strains himself, trying not to let go. Then he decides to pull hard, pulling out the cube. The bubble pops and Finn looks at the cube in his hand. Finn holds it up. "Da-Da-Da-DAAA!" His joy breaks when the cube cracks open and some kind of purple essence flys out and goes on all of the runes in the room. The runes rip off of the dusty stairs and pedestal to float in front of him and slowly form into English.

Young hero, your fate is grim

Finn looks confused. "Whaaaaa-?"

Finn gets cut off by the letters flying into his eyes. "... AHHHHHHH! OWWWW! MOTHER OF GOB, THAT STINGS!" The agonizing pain in his eyes make him fall down the stairs. He sits up, takes off his backpack and reaches in. Finn starts saying "Transport Stone" over and over. He finds a gold stone with a red gem on top. He taps it.

MYSTERY MOUNTAIN DUNGEON ENTRANCE 7:27 PM

Finn teleports at the entrance of the dungeon. He puts the stone in his pack and looks for his cyclopes' tears while hyperventilating in pain. "TEARS, TEEEAAARS!" He finds a bottle of the tears and pours the rest of liquid all over himself. Finn lies down on the floor and breaths heavily. He stands up and growls at the entrance. "You were a lame dungeon!" He throws the empty bottle at it. He looks down to see another Transport Stone, he puts it in his pack. He notices that he looks like a mess. "Ugh." He takes off his shirt and shorts to replace them with a long-sleeved shirt with the sleeves being dark blue, and the rest a lighter shade of blue, and dark blue pants. "Cool." Finn backs up and runs fast. He jumps insanely high and glides at high velocities toward his house. He gets at his door in less then 30 seconds. He pulls up his foot to his face and kisses it. "I love you Gravity Shoes."

TREEHOUSE 7:30 PM

Finn enters his home and drops off the treasure that was in backpack into the gold pile. It has been filling up fairly fast due to his constant adventuring. He climbs up the ladder to see his canine brother sitting at the table. Finn calls out to Jake. "Hey, man."

"Finn! You're finalllllllll-AHHHHHHH!"

"AHHHH! What?! What!?"

"Dude, your eyes!"

"Ey-Eyes?" Finn runs toward the kitchen sink and looks into the water. Finn gasps as he sees that his eyes are now completely colored purple. No pupil or iris. All just purple. "Holy shram..." Finn looks at Jake. "I guess it has something to do with that 'rune jazz'."

"'Rune'?" Jake tilts his head. Finn decides to just ignore the question and stay quiet. Jake changes the subject. "Sooo, whatcha get on the adventure?"

Finn walks to his brother while taking off his backpack. "Stuff. (Southern Accent)" Finn places his pack on the table opens it. He takes out a shield in the shape of an eye. "You see this? This shield makes anybody who is talkin' trash to the holder to cry like babe that just pooped his jams!" Finn keeps a goofy smile on until he sees Jake get serious.

"Finn, I think we need to talk." Finn ignores it And takes out a golden tooth brush with rubies.

"This is the tooth brush of Grod! It makes teeth come back fully healthy! See? I already did it on myself." Finn shows Jake his teeth which are now perfectly alined.

"Finn.." Finn continues to ignore.

"I know you'll like this!" Finn takes out a big chicken leg and bites into it. The bite mark slowly reforms back into it's original shape. "A chicken leg that never runs out!"

"FINN!" Jake quickly stands up and slams his hands down on the table. "Stop stalling now! We need to talk!" Finn puts the leg back into his pack and looks down. "It's important, Finn." Finn's voice starts to become serious.

"What if I don't wanna talk?" Jake groans and walk in front of his brother.

"You don't have a choice. Now tell me why you've been leaving and ignoring all your friends!" Finn's looks up at Jake angrily.

" I don't wanna talk about it!"

"You have to!" They started to shout louder and louder at each other.

"WHY?!"

"Because I'm your older brother! Your eldest in the family!"

"I never had a family! You are all just a bunch of dogs!" Finn is responded with a punch to the face, landing on his back on the floor. Jake intimidatingly points his finger at Finn's face.

"Respect your family, you brat." Finn stares for a while but then gets up and tackles Jake to the floor and punches his face a couple times. Jake retaliates by kicking him off into the kitchen stove. Finn sees a pan on the stove and picks it up. He then swings it at Jake and hits him in the face. Jake growls and picks up chair, slamming it onto Finn's head. Finn falls to the floor and Jake grows his right hand and picks up Finn then throws him at the wall. The wall breaks open and Finn falls on the cold grass outside. He sees Jake come down from the treehouse and gets up. They stare at each other in ready-fighting-stances. Jake gasps when Finn readied his Grass Sword from his right arm. They starts to dash at each other but bump into an invisible wall.

"Huh?.." They both breath out, confused. It seems like they are covered by a force field of some kind. Finn looks behind him to see a tall skinny demon. The demon is all black with red eyes. The demon speaks in a low voice.

"You are the challenger? Pathetic, a child." Finn just stares. Jake asks Finn something.

"Who is that?"

"I... have no idea." The demon shoots a fire ball at Finn. Finn dodges it. "Hey, what the buck, man!" The demon charges at Finn with blinding speeds and grabs Finn by the neck and holds him up. Finn starts to gag. Jake starts to yell.

"Hey! Stop!" The demon throws Finn a couple meters away. Finn readies his sword. He tries to catch his breath.

"Alright, man. You just messed with me, Finn the Human!" Finn charges at the demon and swings the Grass Blade swiftly, but misses ever slice. The demon materializes a red blade from thin air and cuts Finn's right arm clean off. Finn shrieks in pain while blood squirts from his missing limb. Jake starts to go insane, breaking his own fists trying to open the portal with punches. Finn falls to his knees. Finn hears nothing. Silence. The demon walks behind Finn and Jake hears the demon say...

"Like I said.. PATHETIC." The demon thrusts his sword into Finn's back and through his chest. Finn looks down to see a blade sticking out of his chest. Blood slowly oozes out. The demon pulls the sword out and vanishes. Finn falls forward and starts to mumble to himself.

"No... I can't die... I'm the hero of Ooo! I can't die! I WON'T DIE! I-..." Finn stops breathing with his eyes open and a pool of blood around his body. The field breaks and Jake runs to his brother, fearing the worst. He kneels at Finn and holds him in his arms.

"Oh, no.. No, no, no. No! Finn! Don't you dare die! Finn!" Jake's voice starts to break and he begins to sob.

Finn wakes up in a gray place. He looks around to see bones and a Castle of Light in the distance.

"... Aw, crap."
