Fionna—is a 13-year-old adventurer and Cake's adoptive sister. While usually appearing as black dots, her eyes are seen as blue when enlarged. She wears a rabbit-themed hat (similar to Finn's bear-themed hat) with exposed locks of blonde hair. Unlike Finn, her neck is shown. Her outfit includes a teal blue shirt with elbow-length sleeves, a dark blue skirt, and knee-high socks with two thin horizontal stripes at the top. Fionna is heavier set than. She has a green backpack (similar to Finn's) and Mary Jane shoes. Her name was officially changed from "Fiona" to "Fionna," presumably to make it more similar to Finn's name. The pronunciation, however, has remained unchanged. Like Finn and his crush on Princess Bubblegum, it is revealed in many portraits posted that Fionna has a crush on Prince Gumball. Fionna has buck teeth like a rabbit. Fionna, like Finn, is Cake's adoptive sister.

Cake—Fionna's best friend/adoptive sister and Mo-Chro's girlfriend. She doesn't look much like Jake aside from their body proportions. She has white eyes in which the black pupils become circular if surprised, excited, shocked, or scared. She has a cat muzzle and a small nose (compared to Jake's), cat ears, white fur with many coffee colored spots, and a large bushy tail. Cake may know Morse code in order to speak to Lord Monochromicorn, similar to how Jake knows Korean in order to speak to Lady Rainicorn. Cake plays a hammered dulcimer, as opposed to a viola. Her tail "frizzes out" if it is agitated or worried. As a Lumpy Space 'cat', she is a light color of maroon with large spots of fuchsia to match her coffee-colored spots. Her tail is now lumpy and more beaver-tail-like.

Prince Gumball: An 18-year-old gum/human hybrid and Fionna's crush. He is the prince of the Candy Kingdom. Prince Gumball has the same color scheme as his female counterpart. He has pink skin and his hair is somewhat in a quiff. His head is adorned with a small golden crown with a blue jewel. He wears a hot pink shirt with orange-pink puffed sleeves with magenta stripes and under-sleeves (accompanied by dark-pink sleeve cuffs), a large matching collar with a small blue jewel inside a gold crest on it. He has a belt with another gold crest and a small blue jewel design on the buckle, purple striped dark-pink trousers, and dark-purple shoes. Unlike his female counterpart, he also has visible pink eyebrows. Also, when his eyes, enlarge, they are purple. Kind of like how when Fionna's eyes enlarge they look exactly the same, only hers are blue. He also has ears, unlike his female counterpart. His loyal companion is Lord Monochromicorn.

Lumpy Space Prince—is a gender-bender of LSP. Lumpy Space Prince is identical to Lumpy Space Princess only with a mustache and a darker shade of colors. He is most likely 15 years old.

Cinnamon Bun-CB is a citizen of the Candy Kingom, most widely known for her clumsiness and silly attitude. She has milky white eyes, and wears a light green dress with a bow.

BEEMA—it isn't necessarily gender-swapped. I mean, can you really tell if it's a boy or a girl? :P

THE CREEPS

Title Card

The others hunch over Cinnamon Bun's fallen body, weapons hidden behind their backs...

The lightning overhead cracked and boomed, flaring out over the dark sky like an electric spiderweb. Rain hailed down like bullets, smacking the ground harshly. The trees bent sideways in the wicked wind, grass flying into the air by the force. The air sizzled with heat. The waves on the shore churned and slapped against the sand.

Cake observed the scene from the cliff side, about ten miles away. "Boy, we got here just in time, huh?"

"Hoo yeah," Fionna nodded in agreement.

"How much longer 'til we get there?" asked Cake as the two of them continued up the road. The formal event they were heading for had her dressed in a silky purple dress and a matching hat embedded with white roses. A lavender shawl was around her furry shoulders, and white gloves covered her hands.

"Lemme check this ominous invitation that appeared at our doorstep this morning," Fionna replied. She was dressed in a dark green dress that fell down to her knees. The dress had a sweetheart neckline and a wide sash at the waist. She had swapped her Mary Janes for green sandals, and had been willing enough to get a pearl necklace on. Like Cake, she wore white gloves. Fionna had curled the piece of blonde hair that fell from her bunny-ear hat. She reached into her hat and pulled out a parchment card with a half-mask on the front. "Oh...we're here. It's in that tower."

Cake looked up. At the top of the rocky, choppy mountain stood a tall, pristine tower. It was actually pretty well-preserved. The tower was layered window, gray wall, window, gray wall, and so on. There were more windows at the top and bottom. A few windows were broken, and there was a few splotches of rust on the walls, but other than that, it was very well-preserved. The lights also worked, and almost all of the windows were illuminated with them.

They finally reached the tower, stepping on the last of the concrete stairs illuminated by blue solar lights. A chest stood before the sliding glass doors. Fionna stooped down and picked up the note attached to it. "'Wear these,'" she read aloud. She and Cake exchanged confused looks. "'Wear these'?" they parroted.

Fionna opened the lid of the chest. The two girls 'oohed.'

The inside of the tower lobby was surprisingly modern. The floors were made of white carpet, the sleek walls covered in multicolored paintings. There were two stainless elevators on either side of a wide escalator. Sparkling chandeliers, gleaming vases, and pieces of modern art added to the scene. Fionna and Cake observed the lobby with interest. Fionna had pulled on a black and white raccoon mask that only showed her eyes and mouth. Cake had pulled on a simple, sky blue mask that covered the area around her eyes.

"Hello?" called Fionna. There were a few beats of silence, and a voice called, "Over here!"

Fionna and Cake looked to the right, where they supposed the living room was positioned. The sitting room consisted of two square silver couches and a black leather recliner. Acrylic paintings of bright colors were on the walls, and a copper statue of a cougar stood to the right of one of the couches. A glass table and a oddly-shaped lamp stood between the couches. Another sparkling chandelier cast the room in bright light.

"Hey, guys!" called Prince Gumball. He was dressed in a nice, hot pink tuxedo, the collar pressed and not a speck of lint on. His shoes were a darker shade of pink that matched his bow tie. The boy tie cascaded down into white ruffles that covered his chest. His gummy hair was gelled back into a slick. He wore white gloves on his hands, and the area around his eyes was covered in a crystalline mask that looked like an eagle. Fionna blushed, thankful for the raccoon mask.

"Hey, PG," Fionna greeted happily. She paused and chuckled nervously. "That's you, right?"

"Yes, that is I," smiled Prince Gumball. He held up a parchment letter stamped with a half-mask, just like Fionna's. "But according to this invitation, we're supposed to use mystery names. And mine is...Lord Silenthind."

"My name is Duke Gooeytocks," scoffed LSP. He was dressed in a black tuxedo shirt that was rumpled as if he had carelessly pulled it on. The undershirt was bright red, as was the bow tie and the triangular red mask around his eyes. He sat in the recliner, claiming it as his own.

"I am Doctor Skirts," replied Beema. It was only dressed in a simple, Siamese-Cat-like mask that covered its screen. She sat on the left couch.

Cinnamon Bun waved from the right couch. She was dressed in an emerald-green, wide-skirted, puffy-shouldered, long-sleeved dress. The neckline dipped down in a V, the space covered in a pink and purple undershirt. Brown ankle boots and a ridiculously flowery hat accompanied. Her 'disguise' was a pair of insanely thick glasses and a glue-on mole that was mashed into her chin. "I'm Cinnamon Bun."

LSP scoffed and leaned forward to slap her lightly on the arm. "What does your invite say, idiot?"

"Oh, yeah," Cinnamon Bun pulled out the crumpled invite from inside her dress (LSP and Prince Gumball averted their eyes) and read it out. "Uh...it's 'Girl Furting'."

Fionna read her invitation name, chuckled, and did a phony curtsy. "Princess Finebod at your service."

Cake looked down at her name. "I'm Miranda Honeystub." She tossed the invitation over her shoulder carelessly and sat down next to Beema on the couch.

"So," said Fionna. There were a few beats of silence before she continued, "Who's our host, anyways?"

Prince Gumball shrugged his shoulders. "No one knows," he replied.

LSP chuckled and said, "Maybe she'll be a smokin' hot babe with huge cash." He took a swig of the soda bottle in his hand, still chuckling.

Cake made the smuggest smile imaginable and waved a finger at the lumpy royal. "Now, now, LSP. What would your girlfriend Brittany say about that?"

LSP made a bitter, sour face. His hand trembled on the bottle as if he were contemplating on throwing it at a window in anger. "Brittany and I broke up, like, a year ago, idiot."

Cake, Finn, Beema and Prince Gumball gasped in fraud shock. LSP, though as hard-shelled and cool-headed as he was, had always gone into a furious rampage at Brittany's name a million times before. Cinnamon Bun, however, gasped in actual, real shock, her eyes sparkling.

"Now's my chance...!"

LSP's jaw dropped and he glared at her. "No way in Lumpy Space, Cinnamon Bun."

Cinnamon Bun burst into tears, which soaked her icing and caused it to plop to the floor. She took off running for the corner, sobbing and bawling pathetically. Everyone was just about to tell LSP off for causing Cinnamon Bun to cry, when they took note of the parchment envelope taped to her iced back.

"Excuse me, Girl Furting," said Prince Gumball, "There's something on your back."

Cinnamon Bun paused in her crying and tried to reach behind her and grab the envelope, but her arms were so short they just barely brushed her shoulders. "Where?" she sniffled, trying to reach more. "Am I close?"

"Here, I got it," Fionna walked forward and peeled the envelope away from the pastry's back. She shook the icing off with a few flicks of her hand. "LSP, if this says 'KICK ME', I'm going to kill you." LSP rolled his eyes.

Prince Gumball turned to the others with an eyebrow raised. "Did any of y'all put that there?" The response was shaking heads and repetitive negatives. "What does it say, Princess Sweetbod?"

Fionna cleared her throat and read out the invitation.

"Dear guests:

I am your emcee

I am an entity"

The others gasped in shock.

"By the time you have finished,

I will have possessed one of you,

and have you all...diminished"

A shorter, shocked gasp followed.

"We gotta get outta here!" cried Cinnamon Bun. She took off for the sliding doors, her arms flailing behind her.

Fionna called, "CB, wait! Anyone who tries to retire will instantly expire!"

"Nononononono!" CB put her hands in between the cracks in the door and tried to pry them apart. They seemed to be sealed shut, not moving in the slightest. Not even the windows quaked.

Suddenly, all light in the tower flashed out. Lightning flashed outside in a white blast. Thunder boomed all around them, and CB remained silent.

When the light returned, all that remained of the pastry was a pure white skeleton.

Everyone else in the room screamed. LSP let out a girly, high-pitched squeal of "SHE'S DEEEEEAD!" and fell off the couch. There was a sudden, heavy atmosphere in the room, like a hammer had just been dropped down. Panic was just about to ensue when Cake scoffed and said, "That's real nice."

"CUPCAKE, WHAT THE MESS DO YOU MEAN, 'THAT'S REAL NICE'?!" screamed Fionna. Her eyes had gone very large and her muscles were rigid. "CINNAMON JUST DIED AND THAT'S 'REAL NICE'?!"

Cake sighed and stepped over to Cinnamon Bun's skeleton so casually you would think she was walking to the mailbox. She put her paws on her hips and looked at Fionna with annoyance. "Oh, come ON, Fifi. I pulled the exact same trick on your birthday!" She knelt down and, to everyone's horror, plucked Cinnamon Bun's skull off of her skeleton. To make it even WORSE, she put her thumb in the jaw and her other fingers through the eyes like a sick puppet. She made the skull's jaw move as she talked. "I set up all the skeletons, making you think everyone was dead."

Prince Gumball shook out of his stupor enough to shrug uneasily and say, "I-It looks real to me."

Cake scoffed and waved a paw in the air. "So cliche. Use the same trick again."

Fionna pushed up her raccoon mask so Cake could see her sincere face. She frowned deeply. "Cupcake. I swear I'm not pranking you. Cinnamon Bun is dead."

Cake's face went from smug to tragic. She dropped Cinnamon Bun's skull limply.

"The question is," continued Fionna. She looked at the others harshly. "...who killed her?"

"One of us is possessed by a murderer. If we want to leave this place alive, we're gonna have to figure out who it is before they kill again."

Prince Gumball glared at Cake suspiciously. Cake glared back. Prince Gumball glared at LSP. LSP glared back. Beema smiled at everyone.

"BEEMA!"

Fionna's index finger flew down and landed on the small computer console.

"Use your ghost-detecting equipment and scan everyone, would ya?"

Beema flipped open the square holding her controls and dug out three glass vials and cotton swabs. She closed the square and turned to LSP, gesturing for him to bend down. LSP did so and opened his mouth. LSP moved the cotton swab around his cheeks. LSP smacked his lips afterwards. "That tastes like pillows."

Beema swabbed Prince Gumball next. The royal prince moved his tongue around his mouth afterwards to get rid of the dry spots.

Beema swabbed Cake's mouth next. As the computer stuck the swab in its vial, she looked at Cake suspiciously. "Hmmmm..."

Cake rose an eyebrow. "What do you mean, 'hmmmm'?"

Beema shrugged. "Nothing..."

Fionna, LSP, and Prince Gumball leaned in to whisper with one another. "Cupcake..." "Maybe it's here..." "I always knew it..."

Beema tucked the vials back into the compartment and hummed loudly. "Processing data." A few whirs, chinks, and finally, a beep was heard, and Beema smiled up at Fionna. "Data complete."

Prince Gumball looked uneasy. He paused and asked, "So...who's the entity?"

"What?" Beema looked up at them and paused. She was wiping a button with a swab. She slowly put it away, and said, "I...don't have that kind of equipment. I just like taking DNA samples."

"We should find a light source," Cake said. The others gave her looks of confusion, and she explained, "If the light goes out again, we'll be able to see who the murderer is."

"That's a great idea!" Fionna exclaimed. She turned to the others. "We should get some other things, too. Rope, handcuffs, something we can contain the killer with. Cake, Beema, you guys cover the first three floors. We'll take the next three."

"OK..." Cake shrugged and stood with Beema. The two friends approached one of the pristine elevators, and Beema hit the button. A moment later, the elevator doors slid out to reveal a compartment with silver walls and white carpet, a bit dingy but still durable. Cake and Beema stepped inside and hit the next button.

Fionna glared at Cake as the doors closed.

The first three floors of the tower were incredibly dark. The power had not returned to them. The only light came from the flashes of lightning and the glare of Beema's screen. Beema and Cake crept through the halls, darting into rooms and looking around for any light source, but could not find any, as of yet. Cake looked down at Beema and said, "I want the beans, Beema. Is this a prank?"

"No, Cake, this is real," replied Beema. "I know you're scared, and you want to think that this is a joke, but it is real. Cinnamon Bun is dead."

Beema pushed open the next door and looked inside. It seemed to be a supply closet. There was a vacuum, a broom, a duster, and a few cardboard boxes. Beema opened the first one and smiled. It was packed full of flashlights. "Bingo!" she pulled out a flashlight and flipped the switch. A pale white light shot out from the end. She held it out to Cake.

Cake took it with a small squee. She held it up under her chin and jokingly made a scary face. She spun the flashlight in a circle and sighed. "Thanks, Beema...Beema?"

Cake frowned. The hallway was suddenly surreal dark. Pitch black. No light from the lightning, only from the flashlight. Beema was nowhere to be seen. "...Beema?"

"HELP!"

Cake jumped. Something shot past her, brushing against her arm. It felt icy cold and airy, like vapor. She span around and tried to see what it was, but it was gone. Cake whipped around, left to right. "BEEMA?!"

"CAKE, HELP ME!"

Cake spun around. Beema was standing a few feet away, surrounded by darkness. Her Siamese cat mask hung at her side. Her screen flashed horror and terror. "HELP ME!"

Suddenly, a thousand snowy white, icy cold hands shot out from the darkness and pulled Beema out of the light. The computer screamed.

Cake screamed at the top of her lungs. She shot off for the elevator, slamming the button down and darting inside the instant it appeared. "AAAAAAAA—"

"—AAAAAAHHH!" Cake finished screaming when the doors of the elevator opened. She hurriedly stumbled out as if another entity was in there with her. She ran to and fro, screaming at the top of her lungs. "ASSEMBLE! EVERYONE! GET YOUR BUTTS DOWN HERE!"

A minute later, the other elevator opened up and Fionna and Prince Gumball stepped out. The doors shut behind them and they gave Cake looks of confusion. "Where's Beema?" asked Fionna.

"THE ENTITY GOT IT!" screamed Cake. She waved her arms around madly as if they had lost their bones. "WE WERE LOOKING FOR LIGHTS AND WE FOUND A BOX AND THEN EVERYTHING WENT DARK AND A BUNCH OF HANDS PULLED IT INTO THE DARKNESS!"

Fionna glared at her sister and slowly, as if her words were melting, said, "Don't you mean you got it, ENTITY!" she stomped over to Cake so fast and harshly that she absentmindedly knocked Prince Gumball over on his stomach.

He quickly shot up to his feet and stumbled over to the two sisters, saying, "Listen, if there really is an entity, then we need to stick together. That way, if it attacks again, there'll be a greater chance of us surviving."

A scream suddenly ripped through the air. Instantly, the three friends pulled each other in with their arms. The scream continued shrieking, then screamed again, and again. It suddenly struck the three that it was LSP screaming. Prince Gumball meekly called, "LSP, are you okay?!"

The elevator beeped, and three three friends stiffened. The elevator beeped again, then again, and again and again. Finally, it beeped one last time and the elevators opened.

LSP continued to scream until it droned into a bored groan. He huffed, then yelled, "I AM SO BOOORED!" He spun around in the air to amuse himself, then stopped. "I'm huuuuungry." He looked around the room until he found the silver door labeled CAFETERIA. He took off for it. "Food, food, food..."

The others followed him to stick together. The cafeteria was a long, wide room with gray carpet floors and white walls covered in black fleur-de-lis patterns, and oil and acrylic paintings. There was one table in the room, long and sleek, in the shape of a sort of surfboard. The seats were very plush, black cushions on silver-painted wood. The wallpaper was sort of peeling and there was a large water stain on the carpet in the corner, and several chairs had holes in the cushions, but other than that, everything seemed well.

LSP noticed the lack of food, however, and groaned loudly once again. "Where's the fooooooood? This is a poor people's house, I swear!"

"Calm yourself, boy," sighed Cake. She looked up at Fionna. "Any more lights upstairs?"

Fionna huffed. "No."

"Well, there was a box of flashlights upstairs, but I'm not going back for 'em."

Fionna looked at her suspiciously. "Yeah..." She reached into her sash and pulled out the parchment invitation, flipping it open and looking inside. "Let me remind y'all that the invite says that one of us will be possessed."

"Not me," said LSP.

"Someone at this table isn't who they appear to be," droned Cake. She looked around at the others. Prince Gumball was rubbing the back of his neck. LSP was scratching at his stomach through his shirt.

Fionna gave Cake a hard look and slowly said, "That's right, Cupcake." She raised her hands and bent her index and middle fingers in quotation marks. She leaned over her older sister with a harsh glare. "I'm gonna ask you a question only the REAL Cupcake could answer correctly. Who is always with me during my midday hallucinations?"

"A quarter-troll monk."

"Alright, you're Cupcake." Fionna straightened her back and turned to the two boys in the room. "So. Who else was absent when Beema got 'napped?"

Everyone glared at LSP instantly. The lumpy prince rolled his eyes behind his mask and scoffed, "Yeah. I'm the ghoulie. I was looking for flashlights, too, ya idiots!"

"Maybe you were. Maybe you weren't. Tell me this—"

"Why did you dump Brittany?" demanded Cake. When a few beats of confused silence followed her statement, she added, "Only the REAL LSP would know that."

LSP glared icily at the feline and crossed his arms over his chest as he spat, "As if YOU would know the real answer."

"Yeah, I just like gossip."

"IT'S NONE OF YOUR LUMPIN' BUSINESS!"

"How furious," observed Fionna. LSP raised an eyebrow as if to say, 'And?' Fionna brought her finger down through the air and pointed at her friend. "YOU'RE THE GHOST!"

Prince Gumball's eyes flew wide open. He cringed and wrung his hands in front of his chest. "Tie her up before he kills all of us!"

Fionna's blue-green gaze turned to her crush. She squinted and put a hand on her hip. "Strange how you don't even try to defend your best friend. Before we tie up LSP, let me ask you this: What—"

"BRITTANY CAME ON TOO STRONG, ALRIGHT?!" LSP suddenly exploded. Prince Gumball's jaw dropped and Cake's mouth formed an 'O'. LSP slammed his fists down on the table with a growl of rage. "AND I WAS ALL LIKE, 'BRITTANY, YOU NEED TO LAY OFF', AND SHE WAS ALL LIKE, 'FINE, I'LL COME BACK WHEN YOU'RE A MAN!'. BUT I AM A MAN, BRITTANY! ISN'T THAT OBVIOUS? IS. THAT. NOT. OBVIOUS?!"

Fionna paused to stare at her friend, then shook her head and turned back to Prince Gumball. "Answer me this, Prince—"

"WHAT DO YOU WANT FROM ME, BRITTANY?! YOU SAID THAT I WAS THE MANLIEST MAN IN LUMPY SPACE! WHY DO YOU EVEN...ERMAGERD DISIHO RUSRAHING!"

Fionna turned back to Prince Gumball before she was interrupted again. "What did I sing to you on your birthday two years ago?"

"...'Happy Birthday'?" Prince Gumball said in a completely deadpan voice.

"...In what language?"

"Fionna, how on earth would I know? You were just saying 'eh-oo-ee' over and over."

"FRENCH! IT WAS FRENCH!" screamed Fionna. Her eyes went watery and her face flushed red under her mask. "THE REAL PRINCE GUMBALL WOULD HAVE KNOWN THAT!"

"YOU'RE NOT PG!" screamed Cake. She glared at her old friend menacingly and pointed a finger at her. "TIE YOUS UP BEFORE YA START A-KILLING AGAIN!"

LSP's eyes shot up on his forehead. "Whoa."

Cake began to stretch her furry arms around the prince's body, tightly around his arms and legs to keep him bound. Prince Gumball, just before his hand was rendered useless, gasped loudly and pointed at the floor. "LOOK OUT!"

Fionna looked down and jumped. The entire floor of the cafeteria was wavering and lapping like water. It bounced up and down, quavering in a liquid state. Yet, they all stood on it like solid floor. Suddenly, something emerged from the wavering floor. It was transparent and large, having no form, like a mass of mist. It shot around the room, bouncing off the walls and narrowly avoiding the others.

"A REAL ENTITY?" screamed Fionna. The entity shot through her bunny ears, making them fly backward.

"DON'T FRIGGIN' COME NEAR ME, MAN!" LSP yelled at the entity. It whirled around him twice, as if to tease him. LSP picked up one of the chairs of the table and swung it around like a weapon. "DON'T. YOU. FRIGGIN'. COME NEAR ME!"

The entity did several spins in the air before it shot at Prince Gumball. It passed either around or through him, but either way, vanished quickly. The floor returned to normal and the others looked at Prince Gumball worriedly.

The prince's flesh and bones began to melt, turning him into a pink mound of dripping, wax-like liquid.

Fionna and Cake screamed at the top of their lungs. Fionna didn't know what to do. She wanted to cry and vomit and scream at the same time. A cold sweat broke out on her skin, and her eyes were bulging painfully. Her throat was scorching and her eyes were horribly dry. She clutched her sister's shoulders, trembling like a cold Chihuaha. "T-This...wasn't...supposed t-to happen..."

"WHAT?!" Cake rounded on her sister, ripping her hands from her shoulders. She glared up at Fionna with acidic fury. "THIS WAS A PRANK!"

"Y-yeah!" admitted Fionna. She had spent the last month trying to get Cake back for scaring her on her birthday. It wasn't easy at all. First, she had to set a late enough date that everyone could go to. She had to find a place for the prank for occur, and as if led by some strange force, she found the tower. She set up every detail, every action, every little thing that would happen. And everything was going so perfectly... "It was all setup! The doors, Cinnamon Bun, Beema and the hands...Oh, swizz! Beema and Cinnamon Bun are supposed to be in the pantry!"

Fionna took off in a dash for the white door labeled PANTRY. "Guys! Guys! The prank's over. We need to go—AAAAAAAAHHHHHHHH!"

Fionna shrieked in horror.

Cinnamon Bun was mutilated almost beyond recognition. Her body seemed to be destroyed into halves, her upper half plastered in the right ceiling corner of the pantry and her lower half plastered in the left ceiling corner of the pantry. Her body was melted and mushed, dripping and gooey. Fionna could see her eyes, white and lifeless, stuck in all of the horrible mess, as well as several teeth and a tongue.

Cake shrieked, then absolutely shrilled when she looked down.

On the floor of the pantry was Beema. Its face was ripped off its body, laying a few inches away like a discarded piece of trash. Its screen was dimmed and static, but you could see a look of absolute horror on it, as if Beema had been screaming. Wires splayed around like intestines, chips and boards scattered and broken like bones. Beema's small limbs were ripped from its body, and Fionna felt like she were looking at the scene of one of her dolls being broken. Beema's batteries looked fried, and the scene was topped by the Siamese cat mask she wore, which, instead of having a cute little smile, was snarling, sharp fangs unleashed. A chunk of Cinnamon Bun, which happened to also have one of her eyes, dripped down from the ceiling and plopped inside of Beema's body. Fionna felt bile rise in her throat, and feared she would vomit.

"OOOOOOOOH MYYYY GLOOOOOOB!" LSP screamed in horror. He hyperventilated for a moment, his chest pumping and and his mouth agape. He whipped out his scratched, dirtied phone and began to type furiously. "THAT'S IT! I'M CALLING A CAB!"

Every light in the room flashed out.

The room was pitch black except for the blue light flashing out of LSP's cellphone. The misty form of the entity appeared in the darkness, curling and shaping in the air. LSP screamed and flew off in the other direction.

"LSP, WHAT'S GOING ON?!" Fionna shrieked. She couldn't see anything and she was trembling all over. She felt as if something were eating away at her belly.

"GET AWAY! NO!" LSP continued to dash and scream, but it was no use. The entity appeared once more, curling around LSP's body like a constrictor. LSP screamed and thrashed as the entity pulled him into itself, curling away before disappearing from sight.

The lights returned, but LSP didn't.

"WHERE IS HE?!" yelled Fionna. She whipped her head left and right, getting a bad whiplash suddenly, looking for her friend.

Cake pointed at the far wall. "Look!"

In one of the oil paintings on the wall was LSP. The painting depicted a woman with a tall, bony neck, slitted green eyes, flowing black hair, and a dress made out of black feathers and bones waving a hand out in front of her. Crows seemed to blast from her fingers, taking shape and form until every feather was viewable. The crows hailed on LSP, scratching and clawing. The boy seemed to be screaming in horror, his phone still clutched in his hand.

Fionna didn't remember the painting being there before.

"Fifi, I'm scared," whimpered Cake.

A soft, high-pitched laughter drifted through the air. The fleur-de-lis pattern on the wall began to move and curl themselves, spinning and twisting. Fionna and Cake shuddered, their throats caught and speechless.

Something moved in the massacre-filled pantry. A moment later, the entity appeared, curling out of the pantry and moving towards the sisters.

"RUUUUUUN, SISTAH, RUUUUUN!"

Cake grabbed Fionna's arm with her paws and harshly pulled her away from the entity and out of the cafeteria. The two girls stumbled through the lobby to the front sliding doors, drenched with raindrops. "OPEN IT! NOW!" yelled Fionna.

Cake latched her paws between the doors and pulled with every last ounce of strength within her, but the doors didn't so much as budge. "It WON'T!" She screamed. She grew her bottom paw twice as large and attempted to kick the glass of the door out, only for her paw to reel back on impact as she whimpered in pain.

The entity appeared in the lobby, and before either girls could do anything, it shot at them, hitting them very solidly and lifting them into the air. The girls' stomachs lurched and twisted as their bodies were shot around the room. Somehow, they crashed onto the staircase harshly and painfully. Fionna felt a sharp pang in her elbow and Cake grunted in pain as she clutched her knee. Fionna forced herself to her feet and started up the stairs. "C'mon, Cupcake!"

"Alright..."

Fionna ran quickly up the stairs and to the nearest door. She quickly flung it open and turned around. "CUPCAKE! HURRY!"

"Ah! Agh!" Cake hobbled up the stairs, stumbling and tripping as her right leg crumpled on each footfall. "I hit my funnybone!"

She was entirely oblivious to the entity behind her until it was too late.

"CAKEY!"

Fionna screamed as the entity latched onto Cake's lower half like a leech. Cake screamed as she was lifted into the air and clawed for Fionna's hands. Fionna quickly caught her sister's paws and began to pull with all her strength. "DON'T LET GO, FIFI!"

"NO!" Fionna shrieked as Cake's paws began to slip from her grasp. "YOU'RE GLOVES!"

Cake's paws slipped away.

Cake let out one last shriek as the entity pulled her away from her sister, all the way back down the stairs, and into the floor without a moment's hesitation. The floor wavered like water where Cake disappeared.

Fionna fell backwards when Cake was slipped from her grasp and fell on her backside. The room she was in seemed like a filing room of the tower. At least a dozen beige metal filing cabinets were in the room, rusted and moldy. A few drawers were open to see the remains of papers and manilla files inside. Other than that, the room was absolutely plain, with beige walls and white floors.

Fionna panted heavily as the impact of the situation hit her. Cinnamon Bun, Beema, Prince Gumball, LSP, and her own sister were all...dead. Dead. Dead, dead, dead. Just like that. She wouldn't see them anymore, she would wouldn't hear them speak anymore, she wouldn't be aware of their existence from now on. What was she going to do when she returned? The Candy people were going to be devastated! And who would take place as the ruler? And LSP's parents! No dount they would die of grief when the news of their dead sons arrived! Even Cinnamon Bun would be missed! And Lord Monochromicorn would never see his girlfriend again! And now, Fionna would return home every day to a completely silent house. No sisters to pat her on the back when she walked through the door, no computer consoles running up to her to ask if she wanted to play a game.

She curled up in a ball, feeling as hollow as a log and as heavy as a boulder. She was utterly alone.

A sudden sound broke through the air, like wind blowing through trees. Fionna whirled around and saw that one of the walls was trembling like a glitching photo on a computer. A large green mass emerged from it, taking the shape of a monster with scaly green skin and long, greasy green hair and acidic red eyes. It looked to be a male. It smiled down at Fionna as it approached, making all matter around it tremble and waver.

Fionna grabbed one of the lighter filing cabinets and quickly chucked it at the wall. A deep indentation appeared, and she punched it harshly. A small hole appeared, and Fionna wrapped her arms around her body before she crashed her body through the wall.

She emerged in a bedroom with pale blue walls and black floors. There was a large orange bed against one wall, a tall black fireplace with no wood, and two pictures of pure white rabbits. Suddenly, the walls began to expand, taking the shapes of crawling hands. The rabbits began to hiss and snarl in the paintings, leaping out and running around the room wildly. The crystal chandelier in the roof moved and reshaped itself to resemble a sparkling jaw that chomped and bit at Fionna. Fionna flung the exiting door open and ran out of the room.

Fionna ran and ran higher and higher until she could no longer run. She had arrived at the roof of the tower. The cold raindrops felt like bullets against her skin, and the harsh wind brought tears to her eyes. She was soaked within seconds. Lightning flashed brightly overhead. The thunder mad her body tremble.

She ran to the edge of the roof and looked down. The ocean (OCEAN!) had swelled to massive size, lapping at the first few floors of the tower. The bottom half of the cliff was engulfed by water and the rain only helped.

The entity appeared out of the roof. It swirled up in the pounding air, curling towards Fionna menacingly.

Fionna did the only thing that came to mind.

She shrieked at the top of her lungs and covered her face.

The entity laughed.

And not a deadly, deep, distorted laugh, either. It was bright a cheery and very...familiar.

The entity's misty skin fell off to the roof.

Cake sat atop Lord Monochromicorn's head, laughing like a jackal. She continued laughing madly and looked down at her younger sister. "Gotcha! Two for two!"

"...WHAT."

"I found out about you're plan months ago! So I flipped the switch on this play! Boooooy!"

Fionna looked down at her gloved fingers and ticked them off. "So...they're all OK? Beema, Cinnamon Bun."

Lord Monochromicorn stepped forward, his long body pulling along with him. Fionna saw that the others, perfectly alive and well, were with him. Well, not really with him, but in him. As in, everyone's bodies were embedded in Lord Monochromicorn's.

"AWESOME!" exclaimed Fionna. "You can embed people into your bod?"

"- ..-. / -.-. - ..- .-. ... . .-.-.- / .. / -.. - / - ... .. ... / .- .-.. .-.. / - ... . / - .. - . .-.-.-"

LSP murmured something about being ready for Brittany, then promptly fell right to sleep.

Fionna looked over at Prince Gumball. "But you melted!"

"It was a wax figurine. Cake switched me out with it while Mo-Chro was distracting you."

"I CANNOT believe you got me again!" laughed Fionna. She slapped her sister on the arm playfully, and laughed, "With the hair, and the moving objects..."

Cake smirked. "Huh?"

"You know, the painting with the rabbits and the crazy chandelier."

"I...think you were imagining all that biz. We never did that."

"I...don't think I did..."

"Nice try, Fifi," Cake sarcastically laughed. She looked down at her boyfriend and said, "Let's get out of this asylum."

Fionna hopped onto Lord Monochromicorn's back, and all seven of them flew off of the roof into the stormy air. The rain was decreasing to a softer rainfall. The lightning continued to flash, but the thunder was quieter and less like-an-earthquake. Fionna sighed in content and looked up to the sky, marveling at the bright flashes of color. Then, she frowned.

She remembered the green creature in the filing room, smiling at her with its red eyes bright as every matter around it buzzed and flickered.

"...That's going in the Chamber," said Fionna. She closed her eyes and concentrated. "And...it's gone."
