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.

Storytelling

Title Card

Fionna steps into the jungle, the animals, big and small, staring down at her in curiosity.

"Fifi." whimpered Cake tragically. "My teddy. Get me my Tedee..."

Fionna walked over to Cake as she lay in her drawer-bed. Cake had been acting like this ever since she woke up an hour ago: unmoving and whimpering. But Fionna simply guessed that she had finished her book that they had found in some old Fungi War ruins. She had been droning on and on about how tragic it was. What was it called? Blotterchip Frown? Cotterdrip Clown? Something like that. "I'll get your Tedee. Where is she?"

Cake pointed at the corner of her bed, where her Tedee sat. Its fur was copper, one of its eyes missing, and there were three patches covering it. Fionna gave her a questioning look. "Why don't you just get it yourself?"

"Because." sniffed Cake. "I'm siiiiiiiiiiiiiiiick."

Fionna frowned, her eyes crinkling at the sight of her tragic sister. "Poor gal." She reached over to the corner of Cake's bed and handed her Tedee over. "Better?"

Cake suddenly threw her Tedee across the room, where it landed on Fionna's bed face-first. "Too much love." Cake let out a pathetic whine.

"Is there anything I can do?" Fionna asked. They didn't have any medicine, and a simple trip to the hospital may have some complications.

"Rubbie me." pleaded Cake.

Fionna stared at her bizarrely. "Rub you?"

"It's what Mom always did."

Fionna shrugged and rubbed behind Cake's ears-

Only to have Cake swat her hand away immediately. "It's not working! I'm SOOOOOO sick...Can I has some soup?"

"Of course, Cupcake. Just a minute."

About ten minutes later, Fionna came back up into the bedroom. She had to admit, she did a good job at the chicken soup. The chunks of white chicken and the nicely boiled noodles swan around in the gold broth, along with a pinch of basil. She couldn't cook alone. They only had their mother's one cookbook in the kitchen. It was over three feet thick, and had to be kept in the corner. Their mother cooked everything from abalone to boiled zyphome. She cautiously stepped over to cake and held out the bowl. "Open wide."

Cake opened her mouth a foot wide. Fionna poured the contents of the soup down her throat. When every drop was out, Cake closed her mouth, her cheeks standing out like a crazy chipmunk. When she swallowed, her stomach stuck out crazily.

"Better?" Fionna asked.

"Ye-" Suddenly, Cake made a choking sound. Fionna gasped and held out the bowl, knowing what was coming. Cake stretched her mouth over the bowl and let the soup out all over again.

Unfortunately, the contents of Cake's mouth hit the bowl and THEN splashed all over Fionna. Fionna screamed as her face was hit with sopping wet soup. Afterwards, Fionna opened her eyes at her sister. She was in misery, her mouth stretched onto her lap. Fionna helped her place it back onto her muzzle. "What do you want me to do?"

"Tell me a story." begged Cake, her eyes bright with tears.

"Alright." Fionna smiled, thinking of what stories their mother had told them, like Beauty and the Beast and Alice in Wonderland. Finally, she settled on Rapunzel. "Once upon a time-"

"NO!"

Fionna started as Cake whimpered, "I've already heard that story before."

Fionna's forehead crinkled. "But you already heard all of my stories."

"Make me a new one." pleaded Cake softly.

Fionna shrugged. Making up a story sounded easy enough. "I can do that. Once upon-"

"NO!"

Fionna started again, waiting for Cake to explain her outburst. When she didn't, Fionna asked, "What's the matter?"

"I don't wanna made-up story. I need a REAL story."

"Hmm..." Fionna paused. She knew what she had to do: go out, explore, and make up the story as she went along. For Cake. "You wait just a minute."

Fionna ran down the stairs, through the living room, and out the door. "OKAY WORLD!" she shouted at the cloudy blue sky. "GIMME A STORY FOR CUPCAKE!"

She looked around. A star-shaped leaf drifted through the air. When Fionna looked closer, a slug was obviously seen on it. Fionna laughed in triumph and ran back up to the bedroom. "Cupcake!" Her sister sat up excitedly, a beam across her muzzle. "I know a story that will cure you! A SLUG! No, wait. A LEAF fell."

"Then what happened?" Cake pleaded for more.

"The SLUG was ON the LEAF. The end."

At first, Cake only blinked. Then she groaned very loudly and grabbed her stomach. "That story made me feel a million times worse. Fionna, a story has to have...EXCITEMENT!" Her voice rose happily. "Romance." Her features went soft and lovingly. "VIOLENCE!" Her paws went into fists. "Suspense." Her voice was dramatic and her eyes were wide. "And a happy ending."

"But I dunno how to-"

"It's OK, Fifi." sighed Cake. "Just dig me a grave. Actually, two graves. One for my guts and one for my face. Cos when I die, my guts are gonna come spewing out of my face. Imagine that."

Fionna immediately closed her eyes and concentrated. Her brain began to feel like stone. Soon, she was gasping and panting. "I can't do this myself."

"Here." Cake grabbed a piece of paper and very fancily drew a list of story elements. "Make it with all these things."

"I will!" Fionna ran down the ladder.

As she left, Cake jumped out of her bed and began to dance happily. She twisted and swayed and curved. "I'm not really sick! I'm not really sick! WOO!" She did a back-flip.

Fionna walked through the jungle. The grass was dark, the mud black, and the trees were vined and mossy. Random puddles of water peppered the land. Pretty flowers bloomed on the bushes and trees, and fruits, ripe and fresh and poisonous, hung from the limbs. Fionna took out the paper and read the first fancy scrawl: Romance.

"Romance." She repeated to herself. "There has to be a hundred animals kissing around here. I just have to look." So she began. She looked down at a hollow log before her. She ripped off the top and looked inside. A boy and a girl termite were sitting next to each other. "What about you two? Are y'all in love?"

The girl termite was not pleased. Stiffly, she said, "Ki jan ou oze entèvni nan dat nou yo?"

"Uh..." Fionna blinked.

"DISPARÈT mwen anvan m 'chire OUT-OU"

Fionna awkwardly covered the log once more. She searched around until she heard a snoring sound coming from the ground. She looked down to see a small burrow. Bending down, she looked inside and saw a boy and girl rabbit sleeping side by side.

Instead of talking calmly, however, she yelled, "ARE Y'ALL KISSIN' IN THERE?!"

Alarmed, the two rabbits thumped around in their small burrow madly before they crashed into each other and fell on their backs. Fionna frowned. "Maybe I ought to approach more...calmly..." Smiling, she began to march forward. "Normal gal. Jungle gal. Normal jungle gal."

After a few minutes, she came to a small clearing, with only grass and a tree stump. On top of the stump, a bufflehead duck was laying on his stomach. Below, a Fennec fox with her large ears and bushy tail was lying against the stump. Fionna stumbled over something and landed on her face with an oomph. The bufflehead and Fennec jumped and turned to her. Fionna picked herself and began to say something, but seeing how awkward it would be, she began to dig the tips of her Mary Janes into the grass uncomfortably. "So...uh...yeah...um...can I...watch you two...kissing...?"

The bufflehead and the Fennec jumped a foot high and gawked at her. Finally, the bufflehead yelled, "Are you crazy?"

"What the grease, girl?" the Fennec fox scolded.

"Oh...yeah...uh..." Fionna stammered quickly. "I don't REALLY wanna...I mean, that'd be gross...I just...for my sister...She needs...she's gonna die...unless I tell her about you kissing...and fighting...and having a happy ending...if that's alright, I mean."

"What a sicko..." scoffed the bufflehead. "You are one sick weirdo, missy."

"Yeah what's this 'sister's' name, huh?" asked the Fennec fox.

"Cake!" said Fionna. "Her name's Cake!"

"What kind of name is Cake?" the Fennec fox stood to her feet. "Come on, Booba, let's get outta here."

"Yeah, come on, Fennecia." Booba and Fennecia began too walk away.

"NO!" shrieked Fionna. "Cupcake means this!" She lunged at the two of them and grabbed them by their fur and feathers. They shrieked and honked, but soon, Fionna had both of them in her grip. She began to move their heads together with great struggle as they tried to fight back. "Just...c'mon..."

"No!" protested Booba as he tried to clamp down on Fionna's arm.

"W-wait!" Fennecia began to claw at Fionna.

But even so, as Fionna pushed them closer and closer to one another, their beck and muzzle brushed against one another. Disgusted, they pulled away.

"It's just...a kiss..." smiled Fionna while panting.

However, Booba was red with rage. Literally. He looked like a walking fireball. He hissed at Fionna in a very scary way, "WHY DID YOU MAKE ME DO THAT? I'M IN LOVE WITH MS. SWAN. AND NOW I'M SOILED!" He dashed away, his anger leaving puffs of steam in his tracks.

Fennecia cried out in sorrow. Fionna turned to her. "What's the matter?"

"I really DID want to kiss Booba!" cried Fennecia desperately. "I'm secretly in love with HIM!"

"That's great!" beamed Fionna, glad she had some happiness come from it all.

"No." sobbed Fennecia. "Now he'll never love me!" Before Fionna could retort, she pounced away.

"Okay..." sighed Fionna. She really stunk at this. "That was not really normal...But I have to save Cupcake." Angrily, she took out Cake's list of things in a story and ripped out the piece that said 'Romance' and read the next line. "Violence."

After a few minutes of searching through the forest, she found a large lioness sleeping on a bed of grass. Her yellow-gold hair was silky-smooth, and her nails were long and sharp. She looked violent enough. "Hey," Fionna said, but when there was no answer, she yelled it louder. "HEY!"

The lioness's amber eyes fluttered open. She gracefully lifted her head and looked up at the human girl before her.

"Do you wanna fight?" asked Fionna.

The thought of the lioness being regal and elegant and snobby completely vanished. Instead of snarling at Fionna to get lost, the lioness's eyes grew wide and she jumped onto her paws, her silky tail waving back and forth in a blur. "GLOB YEAH! I'VE BEEN WAITING FOR THIS MY WHOLE LIFE!" She crouched down, arching her back in a pounce and snarled-

"Oh no you don't."

A large paw picked her up by the fur on her neck. A lion, obviously the lioness's father, was glaring over her, his claws sunk in her fur to hold her back, his tawny hair in a glowing crown. "I've told you before, no fighting." He gave her a quick bop on the head.

"Okay, listen," said Fionna calmly, "I need someone to fight me. I don't care if it's your daughter or yourself, but-"

"NO!" The Lioness threw herself out of her father's grip. "I'M GOING TO DO THIS! YOU NEVER LET ME DO ANYTHING!"

The Lioness pounced greatly at Fionna, thrashing out her paws. But Fionna simply span, delivering a kick to the Lioness's furry cheek. The Lioness fell in a heap on the ground. The Lion burst into tears and knelt beside his daughter (living) body, glaring at Fionna. "YOU KILLED HER!"

"Dad." The Lioness fidgeted. "Get off."

"YOU KILLED HER AND NOW SHE'S DEAD!"

"IT'S FOR A GOOD CAUSE!" Fionna ran off, panicked. After a few minutes of making sure no one would follow her, she slowed to a walk and sighed. "These animals are crazy. They need help, not messin' with. But Cupcake's gonna die! I gotta keep going!" She took out the list again and ripped off 'Violence.' Now she needed some suspense.

"Let's see..." She looked at her surroundings-a half-buried dagger. A broken, moldy computer. A leaf on the grass. And a small patch of sleeping baby chipmunks in a tree trunk.

Fionna smiled at the sight of the chipmunks. She walked up to the tree and picked up a stick on the ground. She rubbed it together in her hands amazingly fast until a flam caught on it. But as she raised it over the leaves inside the trunk, she began to feel very sad. imagined what was about to happen.

Fionna cackled as she came up to the sleeping chipmunks awake and look up at her. They see the flame on the stick and they fall over, dying of fright. The flaming stick in Fionna's grasp slipped and fell onto their bodies, and a minute later, nothing remained in the tree trunk but ash.

A father chipmunk crawled into sight, his cheek bulging with nuts. He looked around for his children and turned to Fionna. "Have you seen my children?"

Fionna angrily crushed the twig beneath the sole of her foot. "I WON'T DO IT! I HAVE TO STOP! But Cupcake needs me...BUT I CAN'T KEEP HURTING PEOPLE! But Cupcake may die. BuT...BuT..." Fionna's voice changed with every letter. Finally, she just sighed and-

Something hit her on the head. She yelped as pain shot down her neck. She looked down to see a moldy rock at her feet. She angrily turned around, expecting someone. "Who threw tha-" She screamed.

Animals pounced on her. The Lion, Booba, Fennecia, the rabbits, the termites, even the baby chipmunks. And there were a lot of animals she had never even encountered in her journey, like turtles and woodpeckers, and snakes, otters, beavers, squirrels, and so on. Their weight tackled her to the ground. They sunk their teeth and fangs into her skin, causing her to scream. Their claws scratched at her madly. Soon, her skin was covered in bloody scratches and holes where teeth had injected inside her. Fionna squirmed and screamed until she choked out: "ARE YOU GUYS GONNA EAT ME!"

The Lion retracted his fangs from her ear. "You'll see."

Fionna began to sniffle in fear until she beamed in realization. "Hey! This is REALLY suspenseful! Don't worry, Cupcake!" She cried, just as a figure crept up behind her and the animals, a heavy, thick stick in hand. "I'll-!"

And the figure brought the stick down on her head.

Fionna groaned. She felt stiff and sore. She was pressed together, her knees to her chest. She opened her eyelids just enough to look down at her body. Her scratches and sores and torn clothes were completely repaired. But then she noticed she was locked inside something, like a brown cage. She opened her eyes all the way and gasped. All of the animals of the jungle-ever single one-were surrounding her. They were looking up at her as she swayed in the cage, cruel, knowing smiles on their faces. Then Fionna looked down. The cage was swaying over a surging vortex. Random colors swirled around, from air force blue to zymenchlora. Bolts of electricity popped out. Noises sounded out from it, roars and caws of every animal imaginable. "What's happening?" Fionna yelped.

"The Sacrament of Jungle Appeal!" a voice cried. Fionna turned to her left and saw a Jungle Witch. Her hair was long and silvery, shimmering with every move. Her eyes were completely green-no pupils or corneas, just green. Her dress was a shimmering jungle green, with drapes of gold on the sides.

The animals let out a chorus of "Huzzah!"

"Fionna the Human Girl," continued the Jungle Witch. "For your crimes against the animals of the jungle you must enter the Earth and become one with the soil.

Fionna stammered, "D-Don't I get a trial or something?"

"NO! LOWER THE CAGE!"

The cage began to very slowly move towards the vortex. Fionna whimpered to herself. "I'm totes gonna die. And when Cupcake doesn't get a story, she'll die too! Unless she hears my story about dying...that'd be good...But I still don't have a happy ending! Quick, what was the 'happy ending' spell the Merman King taught me? Oh, no, wait, that only works underwater. I know!" Fionna turned to all of the jungle creatures. "OK, obviously, I'm about to die, but it's not too late for you guys! I may be busy dying, but y'all need to get busy living! Booba-" Fionna pointed a the bufflehead. "You love Ms. Swan. Just tell her!"

Ms. Swan gasped in surprise. "What?"

"Yeah, he loves you!" repeated Fionna.

"I've wanted to date you for YEARS!" Ms. Swan exclaimed in pure joy. "You really love me?"

Booba blushed wildly. "I do."

The animals let out another chorus of "Huzzah!"

"Fennecia-" Fionna turned to the Fennec fox. "You need to face the facts: Booba isn't interested. You need to move on."

Fennecia sighed as Mrs. Otter gave her a pat on the back. "She's right. It's for the best."

"And you!" exclaimed Fionna. "Teenage Lioness!"

"What?" the wild cat inquired.

"You need to listen to your Dad!" explained Fionna. "You don't need to go around fighting strangers in the jungle!"

"Yeah!" The Lion gave his daughter another swat on the head.

"Lion," Fionna continued, "Stop swatting your daughter. She's not a baby anymore."

"She's right." the Lion smiled at his daughter. "It's time to let you grow up!"

"HUZZAH!" The animals cheered.

"Mr. Ox!" Fionna turned to an ox-looking creature with a bag on its head. "Take the bag off! Nobody will judge you on how you look!"

"HUZZA-"

Mr. Ox took off the bag.

"-EEEEEEEEEW!" "GROSS!" "AAH!"

"Put the bag back on!" Fennecia cried. Mr. Ox shrugged and put the bag back over his head.

"HUZZAH!"

"SILENCE!" cried the Jungle Witch. She did not look pleased. "Fionna the Human, for disturbing our lives and the order of the jungle...We thank you."

"Whaaaaat?" Fionna beamed in delight.

"Our lives have improved greatly ever since you wandered into this jungle. You are free."

The cage disappeared. Fionna yelped, expecting to fall into the vortex, but the vortex was no longer present. Only earth. Once she had landed, the animals waved goodbye and dispersed to their new lives. Bubbly with joy, Fionna ran as quickly as possible. "I'm coming for ya, Cupcake!"

As the silhouette of the Treehouse stood against the moonlight, Fionna prayed silently, panting and huffing. 'Hang on, Cupcake...' Finally, she burst through the door. The living room was empty, nothing but furniture and treasure and a sleeping Beema. Fionna heard a strange melody from up in the kitchen. Thinking that her sister was already starting her funeral, Fionna climbed like a monkey up the ladder.

She gasped.

Cake was dressed in a frilly pink apron, dancing around the kitchen. At the table, her Tedee sat with a chipped cup before him. Music was blasting from a boom box in the corner. As she danced, Cake mixed up the contents of a bowl. She was singing at the top of her lungs. "I'm not really sick! I'm not really sick! I'm not really sick!" As she did a twirl, her eyes landed on a flabbergasted Fionna. Cake nearly dropped the bowl in her paws. "Fifi!"

Fionna just gawked.

"I-it's not what it looks like!" Cake looked over at her Tedee and hid her under the table.

"YOU'RE NOT REALLT SICK!" Shrieked Fionna. She was seething rage. She had upset all those animals, humiliated and tortured, and all for nothing. Her sister had lied to her. And she had been so worried that she was going to die. "YOU'RE NOTHING BUT A BRUTE!"

Tears welled up in her sister's eyes. "I am a brute. I faked being sick..."

"WHY?!"

"I wanted to be alone so I could do weird stuff. That you wouldn't see..." She looked up shamefully at her sister, who had her back to her. She smiled and put a paw on her shoulder. "But I bet you have an awesome story to tell-"

"NO TOUCHY!" Fionna slapped her sister's paw away. Then she sat on the couch. But Cake noticed that instead of looking angry, she looked dizzy. Her face was tinted yellowish-green. "Fifi, are you alright?"

"I feel sick..." Fionna groaned as she curled up on the couch.

"I know what'll make you feel better." Cake smiled and handed Fionna her Tedee. "My Tedee." She rubbed Fionna's ear. "Rubbie. And best of all: a good story. Once upon a time-"

Fionna snored loudly. Cake smiled. "The end."
