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.

Bunnies-The Bunnies are six kits that come from the first hull. The six kits are all dressed differently: One of them is a witch in a black dress and hat, one is a ninja in a purple outfit, one is a nurse in a white costume, one is a butterfly with wings, one is a angel with wings and a halo, and one is a cupcake.

THE HULLS

Title Card

Fionna squints through the light the box gives off as she opens it

"Cupcake!" Fionna called after her feline sister, panting as she ran. They had been running for half an hour now. She needed a break.

Cake, who had a plate of vanilla cake with strawberry frosting in her paws, turned to her sister, putting another forkful of cake into her mouth. She turned in a curve to face her, but continued to move her feet/paws. "Yeah?"

Fionna stopped before her, bending over on her knees. "Shouldn't we...conserve out energy...?" she panted. "The Cakathon...is tomorrow. 30 miles of all-you-can-eat cake, as long as you keep moving." She moved two of her fingers to show a person walking.

Cake scoffed and took another bite of cake. "I know what the Cakathon is. I've been training for weeks. I am determined to eat more cake than anyone else there. My name is Cake, Fifi. I was born for this."

Fionna looked at her sister curiously. "You sure do like cake."

"Cake is good, Fifi." she took another bite of cake.

There was a distant "creaik" sound.

Cake stopped jogging in place. "What the mammy-jammy was that?"

"I think it came from over here." Fionna turned to her right and walked away. Cake followed, still eating cake.

When Fionna came to a wall of bushes, she spread them apart like curtains. There, standing on a large rock, was a little forest sprite. She looked like a little bundle of leaves, with four twigs coming out for arms and legs. Two rocks and two bendy twigs formed the eyes and mouth. She held a sharp stick as a weapon. "Cupcake, look! It's a forest sprite!"

Cake looked at the sprite. "She's too big for a sprite. I think she's just a bunch of leaves."

"Actually, I'm a forest sprite turned INTO a bunch of leaves." The sprite said, in a chirpy-bird sound, before letting out a "creaik" sound. "I just continued being a sprite."

Fionna and Cake approached the rock she stood on. "And now you're, what, attracting a mate?" Fionna asked.

"Wh-? No! I'm on the brink of death!" the sprite exclaimed.

"Oh." Cake said. "Well, you should just let go, girl." She looked about to take a bite of cake, until she realized her fork was missing. She looked on the ground around them.

"Yeah you've had a good run." Fionna assured the sprite. "Go enjoy the afterlife."

"I cannot leave this life until I find a being pure of heart and full of spirit," The sprite 'creakied,' "to take over my quest."

"QUEST?" Fionna exclaimed in a bubbly voice filled with hope.

"Uh-ohhhhh." Cake smirked. "Someone's gonna do a quest for a bundle of leaves."

"Tell us more about this quest." Fionna sat down with her legs crossed, like a child waiting to be read a story. Cake set down next to her, her plate of cake in her lap.

"It's very, very crucial." The sprite reached behind her and took out a box. It was no bigger than a baseball, and was decorated with flowery designs. "I must guard these magic seeds."

Fionna and Cake stared. "...What now?" asked Cake.

"Two of these seeds are good." The sprite explained. "But one is demonically evil! I have no idea which is which, they keep getting scrambled up. So I've spent my life guarding them to prevent them from being planted.

"...Seeds." Cake said shortly. Then, chuckling, she stood. "Magic seeds, ha ha. We'll be right back. C'mon, Fifi, I think I dropped my fork in the bushes."

"We shall accept your quest!" Fionna declared to the sprite.

The sprite looked surprised. "Really?"

"Sure, why not?" She picked up the little flowery box. "Consider it protected."

"Also, I want you to take this." The sprite held out her sharp-stick weapon to her.

Fionna took it. It really looked like a gigantic tooth-pick. "Thanks...?"

"No, thank you." A silvery-green mist appeared around the sprite. She took a deep breath, like she were breathing fresh air after being inside somewhere so long. In one breath, her leaves fell away into the breeze of the wind. A little green girl-sprite now stood on the rock, with long forest green hair and light green skin with a oak-leaf dress. Fionna stared in awe.

Cake walked up to Fionna with her fork in hand. "What'd I miss?"

"We took up the quest."

"What?" Cake exclaimed in annoyance. "The seeds? Hold on-"

"Too late she accepted." And with a little flash of green light, nothing remained of the sprite but a little purple orchid.

Fionna and Cake gaped in awe. Fionna sighed. "I miss her already."

"Well..." Cake turned around. "We should get a move on, if we wanna make it to the Cakathon."

"What about the quest?" Fionna help up the tooth-pick and the box.

Cake walked back in surprise. "We're seriously doing the seed quest?"

"I gave her my word." Fionna said in a whispery voice."

"Yeah..." Cake twirled her fork in the frosting of her cake. "I wasn't here for that, so...can't we be guards AND eat cake?"

"No, Cupcake. We're on the job. Like you always say: 'work and fun don't mix...'"

"...'unless you're a clown." Cake sighed. "I do say that a lot.

AN HOUR LATER

They were bored out of their minds. They stood on either side of the rock, in the hot sun, with nobody or thing coming into view. Fionna sighed. "Clear on this side. How about your side?"

"All clear." huffed Cake, not understanding why SHE had to do this if SHE wasn't the one who swore to do it. "No one coming to plant those stupid seeds." She scraped her now-empty plate with her fork, trying to pick up the remaining frosting. She groaned. The sun was making her fur damp with sweat, and her tail was limp. "Gee, sitting in this hot, blistering sun sure does beat thirty miles of vanilla cake...or strawberry cake...or mint cake..."

There was a long silence.

A light-bulb almost appeared above Cake's head. "Hey! Why don't we plant the seeds ourselves?"

Fionna turned to her as if she had gone mad. "Are you nuts?"

"Hear me out." Cake gestured to the flowery box sitting next to the orchid. She opened the box, showing the three small seeds. "If one of these seeds is evil, then it's our job to crush it once and for all."

Fionna seemed to be considering it.

"Plus, don't forget that two of the seeds are good! If we plant all of them, we'd be letting twice as much good into the world!"

"Plus, we could make it to the Cakathon!" Fionna chimed in happily.

"I hadn't even thought of that!"

So they planted the seeds,

And waited for evil to grow-ho-oh!

So they could kill it, and go-ho-ho,

To the Cakathon.

The night sky was deep blue, speckled with bright stars. The moon shone down brightly, covering the land in silvery blue light. Fionna stared at the three little dirt humps where they had planted the seeds. They and waited all day for them to grow, and they hadn't even seen the slightest signs of growth.

Cake reached into her sister's pack and took out a feather pillow and blanket. "I'm taking a catnap."

"But we have to be ready for the evil!" exclaimed Fionna.

"Let's do it in shifts, Fifi. If we stay awake together, we'll both get tired and fall asleep at the same time. If we take shifts, one of us would be sleeping and the other would be keeping guard."

"That's a good idea." smiled Fionna. "You're pretty smart, for a lazy bum."

Cake snored.

Alright, Fionna. The ground is ripe with evil. Evil that could sprout at any moment...like...RIGHT NOW?!

Fionna stared down at the dirt. "I would stab you right now, if I knew which seed you were."

After another hour or so, Fionna shook Cake's arm drowsily. "You're shift."

Cake slapped her hand away in her sleep.

Fionna looked down at the dirt, watching as the silvery blue light of the moon got darker and darker...

Fionna felt the ground shake. She groaned in her sleep, wanting to rest just a bit longer. Fluttering her eyes opened, she screamed.

A GIGANTIC stalk rose before them, with car-sized leaves and a green surface. Fionna unsheathed her ruby sword. She shook her feline sister. "Cupcake! This is it!"

"Huyah?" Cake sat up, rubbing her eyes and yawning. "Fifi, your shift isn't over yet. I still have eight more hours-" she suddenly caught sight of the stalk. "MOTHER GOOSE!"

A shadow began to grow on them. Looking up, they saw a large hull coming down to them, a slit going down its side to open. They stepped back as it came down to the floor. Fionna gripped her sword so hard her knuckles turned white. But after a few long moments of the hull being still and unmoving, she let out a frustrated cry. "I CAN'T TELL IF IT'S EVIL YET!"

In answer, the hull began to tremble, giving off a sound like a rumbling stomach. Fionna set her jaw and prepared for whatever evil was to come. Cake made a shield with her hands. Just as the slit of the hull burst open, Fionna let out a warrior cry-

And froze. "Wha-?"

Six baby bunnies were sleeping in a pile before them, snoring softly. They were all dressed in different costumes, like little Halloween children. One was a witch, with a black spider-web-like dress and pointed hat. Another was a ninja in a purple uniform. Another was dressed as a butterfly, simply with a pair of wings on its back. Another one was a nurse in a white dress. Another was an angel, with white wings and a hovering halo. The last one was dressed as a cupcake, complete with a wrapper and sprinkles.

Cake let out a bubbly squeal and knelt down next to them. "Look how adorable they are, all sleepy and dressed up!" She squealed again.

"Careful, Cupcake. This could be a trap. We should test them to see if they're...eeeevil..."

All the bunnies were seated in old-school desks, yawning and rubbing their eyes from their sudden awakening. Fionna handed out the test sheets to them, while Cake handed out the pencils. "Alright, you each get one test and one pencil. Cheating is strictly forbidden. If your test results prove you to be fairly good, we will not kill you. You all have one hour to complete the test." Fionna picked up her sword. "And...begin."

*ONE HOUR LATER*

By the time the tests were to be taken up, all the desks were toppled over, the sheets were scattered, the pencils laid around at random, and all the bunnies laying on top randomly.

Cake cooed. "Look how they can barely hold their pencils."

"That doesn't go good towards their grade point average."

"Nothing evil can be this ADORABLE!" Cake gushed as she watched the nurse bunny scribble on its test sheet like a toddler drawing a picture.

Fionna picked up all the papers and stacked them evenly. She looked down at the tests sheet before her.

yoo liKe puppeEs?

yoo haVe allerGieS?

yoo eaT panCakes?

is yooR miDDle nAme?

"The only thing on here is a cute drawing of a cake under 'do you have allergies?'. Nothing evil. Alright, the bunnies are good."

"YES!" Cake ran over to the bunnies, bouncing up and down. "You gals hear that? You passed! School's out!" She picked up the nurse bunny and began to toss it into the air, catching it as it silently laughed.

The bunnies hopped around excitedly. Fionna smiled. "They are adorable!"

There was a rumble from the earth beneath them. Fionna watched as a huge stalk, identical to the first one (but blue), erupted from the earth. "Cupcake, get ready!" Fionna quickly picked up her sword. "The second hull is coming! Protect the bunnies!"

"Come on, my darlings!" Cake picked them all up with huge hands and stepped away.

A huge hull fell down before Fionna with a loud 'thump!' "SHOW ME WHAT YOU HOLD WITHIN, HULL!"

With a 'splortch,' the hull burst open.

A mountain of mufti-colored candy fell onto the earth, their wrappers shining in the sun. The hull shriveled away. Fionna stared. "Candy?"

"Holy balognas!" Cake let the bunnies go and dashed over to the mountain of candy, and reached for a silver one with rainbow dots.

"Stop, Cupcake!" Fionna cried. "It may be-!"

Cake popped the candy into her mouth. It tasted like strawberries and pears. In seconds, she felt a tingling in her paws. Looking down, she saw multi-colored sparkles shimmering from her paws. She moved one paw up and down, and the sparkles continued to erupt from it. "IT'S CANDY THAT MAKES YOUR HANDS POOP GLITTER! WHAT'S GOODER THAN THAT?"

Cake took a bunch of candies and brought them to the bunnies, who bounded to them excitedly. Fionna noticed how they avoided some candy, like the bright red and the black ones, but shrugged it off.

Fionna sheathed her sword and picked up a rainbow-striped candy, popping it into her mouth. She felt her mouth tingle. She blew out a breath, and a rainbow burst form her mouth before disappearing. "Gliter candy COULD be evil. But RAINBOW candy? OVER MY DEAD BODY." When the rainbow magic disappeared, Fionna sighed tiredly. "Now we only have to wait for the evil hull to come. Then we'll destroy it."

"And then we're off to the Cakathon!" added Cake cheerfully as her fur turned blue to orange to red to green. "And we'll eat until we throw up!"

"Meanwhile, I'm pretty sure we've got a lot of time to kill." said Fionna. "You think these bunnies know any games?"

*THREE GAMES OF PATTYCAKE, SIX GAMES OF CHECKERS, FOUR GAMES OF SOCCER, AND ONE HOUSE LATER*

Fionna wiped the sweat from her eyebrows. The house they had built was rather small, but big enough for all the bunnies to stay in together. She dropped down to the grass, sitting up against the side of the house.

"I'm exhausted." panted Cake. The witch bunny, the ninja bunny, and the butterfly bunny snuggled up to her.

Fionna smiled as the other three bunnies laid against her. "They look so adorable when they're sleepy. But we have to stay alert. The evil hull could appear at any time. When it does, we have to destroy it."

"I'll take the first shift." Cake said tiredly, the bags under her eyes dark and heavy.

"Thanks." Fionna barely finished the word before she fell asleep.

Cake felt her eyelids get heavier by the second. She snapped herself awake, knowing she promised Fionna.

That was when she fell asleep.

Fionna's eyes split open. With a yawn, she looked around. How long had she been asleep? It felt like she had only been asleep for a few-

Wait. Asleep?

SLEEP?

SHE WAS SLEEPING?

"CUPCAKE WE FELL ASLEEP!" Fionna's shrill cry snapped Cake awake immediately.

The feline let out a cry of surprise when she saw the truth as well. She looked up at her sister, who had her mouth wide open. "Fifi?"

Fionna pointed up.

The last pod was hanging before them. IT WAS GIGANTIC. The size of a helicopter. It was bulging and moving, ready to burst at any moment.

"Is this the evil one?" Cake asked.

"Yeah." Fionna unsheathed her sword.

"This one is way bigger than the other two." Cake muttered nervously.

"We gotta kill it, right now." Fionna said as she approached the bulging hull.

As if snarling at them, the hull began to shake and rumble. Fionna and Cake let out battle cries.

They jumped on top of the hull. Cake pounded it with her giant fists. Fionna slashed at it with her sword. But no matter how hard they attacked it, they barely made a dent. This hull was way thicker than all the others. But they didn't stop. Fionna continued to hack at the hull with her sword. Cake jumped back down to the earth, continuing to pound at the hull. She punched it again, and felt the hull sink a bit beneath her fist. Opening her eyes, she saw a little opening in the hull. Something pink could be seen inside. "Fifi, come look at this!"

Fionna jumped down to her sister and looked inside the hull. "What is that stuff?"

"I dunno." Cake reached inside and patted the thing to see if it was safe to grab. She tore off a chunk of the stuff and examined it. It was soft and pink and fell into little crumbs in her paw. Curiously, she took a bite of it. "This stuff tastes good, Fifi. Exactly like strawberries." She reached inside and tore off some more.

Fionna gawked at her sister. "Don't EAT it, Cupcake! It's evil!"

"No it isn't." Cake opened the opening in the hull wider. She gasped. "IT'S CAKE!"

Fionna looked inside and gasped. It was cake. Mountains and mountains of cake of every kind. Almond cake, banana cake, caramel cake, hazelnut cake, lemon cake, orange cake, strawberry cake, vanilla cake, chocolate cake, peanut butter cake, red velvet cake, mint cake, and so many more. It was a cake-lover's dream.

Cake reached inside and, with both paws, ripped off some red velvet and white chocolate cake, stuffing it into her mouth. She shoveled cake into her mouth wildly.

"Is the evil sucking you in?" asked Fionna worriedly. Cake's body began to swell like a balloon. "CUPCAKE?" She grabbed her tail and pulled her out.

Cake was smiling deliriously. "That was the most amazing experience of my life."

"Are you poisoned?" Fionna said in a blur. "How do you feel? Count to ten!"

"I'm fine, Fifi. Really."

Fionna noticed a movement in the hull. "Cupcake, look! It's filling back up!"

Cake looked inside. It was like she hadn't even a single bite. If anything, there was more cake than before. She took her tongue and scooped up a chunk of cake. It refilled itself. "THIS HULL MAKES CAKE OUT OF NOTHING! THIS IS THE GOODEST THING THAT'S EVER HAPPENED TO ME!"

Fionna looked baffled. "But if THIS isn't the evil hull, then which one was...?"

They stood there in thick, heavy silence as the sun beat down overhead. The cake was definitely good. And the candy showed no harm. But if it wasn't the cake, and it wasn't the candy...

Fionna spoke up. "The bunnies are gone."

"And so is the candy." added Cake.

There was yet another silence.

This time, it was broken off by a shrill scream. Fionna and Cake jumped. The scream was followed by a sparky blast. They ran and ran until they came to a wall of trees, which they burst through.

Flower Town was under attack. The houses, all tall, hollow flowers with windows and doors, were smoking. Sparks were flying everywhere. Puffs of multicolored smoke burst from nowhere. And who were the people causing it? The bunnies. As the two girls watched, the bunnies took out candy after candy. Not the pink, sparkly ones from before, but the ones they avoided eating. One bunny ate a black one. The shadow beneath her rose from the ground, forming monster that attacked a nearby house before disappearing. Another ate a red-orange-and-black-swirled candy. She touched a nearby wagon, and it melted into a pool of lava.

Suddenly, the bunnies didn't look so adorable anymore...

Fionna and Cake dashed to the witch bunny and the angel bunny. "BUNNIES! STOP IT!"

The bunnies glared at her. In the blink of an eye, they ate two electric yellow candies. They both waved their hands. Fionna and Cake didn't have time to even breath before a hot bolt of lightning shot at their feet. The blast was so harsh and fiery, they were blasted all the was back to the three stalks and the cake-hull.

"Crum!" Fionna kicked a rock, sending it flying. "Those bunnies come on actin all cute like 'yeah, we're all good and stuff,' but they were playin' me the whole time! YET DEEP IN THEIR CURSED SOULS, THERE MUST LIE SOME WEAKNESS."

"I found my weakness." Cake said, reaching into the hull and taking a bite of raspberry cake.

A light-bulb as big as a car popped over Fionna's head. "THAT'S IT! THE CAKE!"

Cake turned to her sister, red icing smeared on her muzzle. "What about the cake?"

Fionna dashed over to the empty desks they had used earlier, picking up all the test sheets. "Yes!" In a matter-of-fact voice, Fionna turned to her sister. "The exams confirm my memories of the bunnies being allergic to cake."

Cake let out a shrill scream. Fionna jumped, thinking the cake really had been poisonous and was now killing her sister. Cake laughed apologetically. "Sorry. Just the thought scares me."

Fionna jumped on top of the hull. With a slash of her sword, she broke off the stem holding on to it. Cake lifted the hull up, and the two girls took of towards the village.

The bunnies were still wrecking havoc when they arrived. As Cake continued to carry the hull, Fionna jumped on top. "I see one! Get ready to attack!"

"Ready!"

As they approached the witch bunny, Fionna reached inside the hull, took out a full red-velvet cake, and tossed it at the witch bunny. It splattered all over her. The witch bunny froze for a moment. She began to break out in purple boils.

"It's just making them break out!" Cake called up to her sister.

"They're not allergic!" exclaimed Fionna. "Those cheaters lied on the exams!"

Cake gasped. "They really ARE evil."

And as if to prove them wrong, the bunny exploded, sending mulch-colored sprinkles everywhere.

Fionna stared. "I guess they are allergic to cake..."

Cake screamed again. Fionna jumped. "Sorry. It still freaks me out."

The nurse bunny popped a black-and-purple swirled candy into her mouth. Her paws shimmered purple just before she fired a heavy blast at Cake.

"CUPCAKE!" Fionna yelled.

Cake groaned and picked herself off the ground. She then froze. Her feet began to tap.

Fionna watched. "...Cupcake?"

Cake began to move up and down. She began to kick her feet as her tail began to twirl. "I can't stop dancing!"

"WHAT?"

"It must be the candy!" Cake said as she began doing the Roger-Rabbit."I gave me a serious case of boogie-fever!" She began to do the worm. "Go on without me!"

Fionna lifted the hull onto her shoulders, surprised by how light it was. She ran off to get more bunnies.

"You can do it, Fifi!" Cake called, doing some disco-moves. "Just believe in yourself!"

Fionna glanced back at her. "That's pretty cliche."

"Sorry. It's the candy."

Fionna dashed further into the town, and spotted the angel bunny. "HOPE YOU SAVED SOME ROOM FOR DESSERT!" She tossed some cake at the bunny, and it burst into sprinkles. "SWEET DREAMS!" The nurse bunny was gone now. "I'M KILLING YOU WITH CAKE!" The ninja bunny and the butterfly bunny exploded.

"Yeah! Go Fifi!" Cake called as she began doing the sprinkler.

Fionna looked around the village. Her face fell.

The little cupcake bunny was sadly staring at the grass underneath her. The candy she had was piled beside her. She looked up at Fionna with big, apologetic eyes. "Cupcake, there's one left, but I think she's surrendering."

"KILL IT!" Cake called.

"But she's dressed as a little fluffy cupcake. It's frickin' adorable!"

"EVIL NEVER SURRENDERS! KILL IT!"

Fionna looked down at the cupcake bunny. "Sorry..."

The bunny mumbled something.

Fionna tried to reach inside the hull, but the hull seemed to be stuck. In fact, it didn't seem to be refilling. "Cupcake, I think it's clogged with icing or something!"

"I'm on it!" Cake shuffled over to her and the hull. She set her muzzle to the hull and began to suck out the icing and frosting. Fionna felt the hull get heavier. "You're doing it!" Fionna looked down at the bunny, who was pawing through the candies beside her. "Hurry!"

"Almost...got it!" Cake reached inside, took out a big wedding cake, and threw it at the bunny just as the bunny threw a handful of fire at her. The two hit each other and soared into the air, blasting in the sky like fireworks. Cake fell everywhere, and a big chunk fell on the bunny. It broke out in purple boils just before exploding into sprinkles.

"Thank you for saving our town." the mayor of the village, a little daisy flower, smiled as other townspeople crowded behind her. Apparently, the dancing candy was affecting them as well.

"You're welcome." Fionna said as the candy forcing her to dance began to wear off.

"Now, if you will excuse us, we need to remove all this cake from our homes and businesses." a little rose-girl said.

"Not so fast!" They all turned to Cake, who held up a fork. "I'll take it from here, folks." Giggling madly, she dashed towards the village, shoveling cake into her mouth.

Fionna smiled at the surprised townspeople. "She just really likes cake."

STORYLINE ANALYSIS

Fionna accepted a quest to guard the seeds from ever being planted. Whether she thought it through or not, she had agreed to sit by the seeds for an indefinite amount of time. She was saved from this by taking Cake's advice to plant the seeds, but technically, Fionna failed forest sprite's quest.
