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.

Corn Dog Knights-a group of hopelssly stupid canine-like corndog creatures. They serve Corndog Prince, and they typically wear medieval armor and bear medieval weapons.

Ignisnobis-(IG-NISS NO-BISS) a magical creature in the center of the Maze. She is a lizard-like creature made of stone, with cat-like green eyes, and her limbs end in scaly paws. Ignisnobis appears to be wise and friendly, but she is actually deceptive and cruel. She also speaks with a hiss.

THE MAX

Title Card

Fionna and Cake stand before the entrance of the Maze, the small group of Corn Dog Knights right behind them, their eyes wide.

"I got another one!"

Cake cupped her paws around yet another firefly, the small insect buzzing between her claws. She stepped back over to Fionna, who opened the holed lid to an already firefly-filled jar (carefully, so as not to let any out). Cake set the firefly inside with the others, and they marveled a moment at the bright gold insects that seemed to dance inside of the glass.

They were in the middle of a field. The dry grass came up to Fionna's knees (and Cake's, as they were stretched out), dancing and bending in the soft wind. The few trees in the field bore leaves that flickered from black to silver in the moonlit breeze. The moon was incredibly bright, and the stars in the sky twinkled. The entire field seemed to be filled with stars, as there were millions of fireflies everywhere. A dozen jars were stacked up in a small clearing, filled with about six fireflies each.

"That makes thirteen," Fionna said as she put the jar on top of the shortest stack of the firefly-filled-glass-containers. With the number of bright in insects, and the glass that magnified their light, it seemed as if there was a golden beacon in the field. "Is that enough, Corndog Prince?"

"I think two more should do it," the small, batter-covered, edible, canine royal replied, looking at the stacks of fireflies with a pleased smile. "Thank you both for helping me with the Semi-Annual Firefly Harvest, girls."

"Our pleasure," Fionna told him with a smile.

Cake looked all around her at the millions of flame-like insects. "You know, these fireflies look like falling stars. Wishing stars."

"I wonder if we'll see one tonight," agreed Fionna, looking upwards. "What would you wish for?"

"That something special only the best of sisters can have."

You could almost see the excitement and joy coming from Fionna. "I think I know what you're talking about!"

"The Archaic Cerebral Velocipede Battle Mammoth!" the two girls chorused together in glee.

"You girls have been talking 'bout that Mammoth all night," Corndog Prince smiled. "What is it?"

"It's a totally rad recreational beast that can read your mind and take out an entire army! They're so amazing they take A THOUSAND YEARS to train!" Eyes wide and sparkling in awe, Fionna turned to Cake. "I hear that you can't choose your Mammoth. IT chooses YOU."

"I WILL HAVE A MAMMOTH CHOOSE ME BEFORE I DIE." Cake proclaimed.

Their eyes went back up to the sky, and when they did, they gasped. A bright spot of light was whizzing through the sky, leaving a trail of silver behind it. "It's a wishing star!" Fionna exclaimed, green eyes bright in glee. "MAKE A WISH! QUICK!"

Then, suddenly, the 'wishing star' burst like a firework, leaving only four letters:

C.A.K.E.

Fionna's nose scrunched up. "Wha-?!"

Cake gasped. "MY PEOPLE."

Corndog Prince gasped in horror. "It's a Corndog Knight S.O.S.! I sent a group of them to rescue ANOTHER group of Corndog Knights, but they never came back! It says, 'Come Aid/Kiss Eus."

Fionna's eyebrows crinkled. "'Eus?'"

"Fionna, Corndog Knights are HOPELESSLY stupid. Especially in literature." Corndog Prince sniffed, looking over at her Corndog Captain, who was writing 'EI LUV EYCE KREEM' in some mud.

"We'll go get them," Fionna told the royal.

Fionna and Cake gawked at the Maze before them. The walls were tall (tall enough to brush the clouds) and made of solid metal, with mouth-decorated pillars scattered around. Trees, fiery explosions, and wreckage were peppered around randoml, along with some other macabre things. The air was filled with metallic screeching and beastly roars, with a hint of gunfire. The Maze seemed to go on for miles and miles, never ending. It went into the horizon.

"This place is GINORMOUS!" Fionna gawked at the scene before her.

"Fifi, everything is ginormous to you."

"I can't help it. I live in a small world."

As the two girls approached the entrance (which was modeled after a lion's head), Cake looked up at the walls as far as they could before they disappeared into the clouds. "Maybe I can stretch us over or somethin'?"

"No, we can't. Look."

Cake looked at the small plaque on the metal wall. The words 'Si fraudatis morieris' began to mold and squirl until they depicted 'If thou cheat, thou shalt die.'

"Oh," commented Cake. She looked around for a moment before a small lightbulb went off. She walked over to a tall oak tree and turned her back to it, wrapping her tail around it. "Ta-da!"

Fionna cheered. "There ain't no cat like a stretchy cat-"

"-cos a stretchy cat never stops!" Cake finished as they entered the Maze, laughing.

"This Maze goes on forever," Fionna commented as they passed the forty-seventh passage since they entered the Maze. Fifty-second, if you counted the trapdoors. "It'll take us flippin' forever before we find those-"

"Fifi?"

"Yeah?"

"There's a corndog on your shoulder."

Fionna turned her head and saw a small corndog female grinning up at her. "AH!" Fionna screamed and slapped the creature away.

It was then she became aware that it was a Corndog Knight. The Corndog Knight fell to the ground, and three more formed a V around her. The other Knights glared up at Fionna, holding up small needles of wood in a threatening manner. Toothpicks. "How dare you bloody attack one of our sheilas?" the one to the left cried, her voice muffled by a mouth scarf.

"No, no! Corndog Prince sent us here to rescue you all!"

The Corndog Knights immediately sighed in relief, lowering their puny weapons. "T'ank our lucky starhs!" the one in the front, with an eyepatch, exclaimed. "Weev been lahst fir haours! Wahy deedn't yew garls git lahst?"

"We're gonna follow Cupcake's tail back," Fionna smiled, gesturing to Cake's stretched tail, which disappeared behind the corner.

The Corndog Knights gasped in wonder, and Cake was showered in compliments of awe and idolism. "Ahmazin'!" "Beaut!" "Thou art so amazing!"

"There is a magical creature in the center of this Maze that grants wishes to whomever approaches it," the Knight with no left arm proclaimed.

"Wishes?" Fionna and Cake repeated. Fionna gasped and turned to Cake. "CUPCAKE! DO YOU KNOW WHAT THIS MEANS?!"

"The Archaic Cerebral Velocipede Battle Mammoth!" The two girls exclaimed in unison.

"Come on, girls!" Cake said, grabbing all of the Knights in one paw. "We're gonna get us some wishies!"

The Knights cheered madly.

Fionna: Dance cause yo dada, yo dada, yo dada said.

He said yo dada, yo dada, yo dada, what?

What yo dada say, he say?

Cake: I'm busy, meetin' ladies

Pretty ladies

Dancing through the daisies.

I might marry them, maybes.

Fionna looked down at Cake and frowned. Her hind legs had disappeared, and her torso was only as wide as a soccer ball. This wasn't normal. Before Cake could get to the opera solo, Fionna asked, "Cake, what happened to your legs?"

"What?" Cake looked behind her. "Oh. Must have lost them a while back. No biggie."

"Cupcake, you're bod's gettin' bad."

"Wh-? I'll have you know that I have only cheated on my diet twice this week, Fifi."

"No, Cupcake, I mean it's getting skinny."

"Hm. Maybe I need to cheat more often..."

"Cupcake, you're not getting the-"

Fionna was cut off as something long, thick, and scaly wrapped around her torso and chucked her against the wall. She grunted as she hit the floor, and she opened her eyes dizzily. When her vision cleared, she gasped. "BASKILISK!"

A gigantic, slimy, scaly Basilisk was between the girls. It's scales were sharp and black, and its eyes were a flaming orange. Black spikes adorned its head. Venom dripped from its foot-long fangs. It hissed at the two girls, splattering its venom everywhere.

Fionna charged forward. She ran up the Baskilisk's back as if it were a slimy staircase. She then took out her ruby sword, which twinkled a dull red in the light of the Maze. She jabbed the sword's blade into each of the Basilisk's eyes. Green blood dripped down the Baskilisk's scales, and it snarled in pain. "Quick, Cupcake! While it's blinded!"

"OK!" Pushing off the Corndog Knights, Cake began to wind herself around the Baskilisk, up and up before she began to wrap herself over and over around its jaw. The venom dripped on her fur, and it burned. As she continued to wrap herself around the Basilisk's jaw, she began to feel her body stretch out. She pulled and pulled, but she was like a rubber band pulled to its max. "I can't...stretch...any more..."

"You can do it, sheila!" the scarfed Knight cheered. "Barrack! Barrack!"

Cake stretched harder and harder. Her spine crackled and her organs wrinkled. Finally, the Baskilisk fell to the ground in a heap of scales.

"Oi! Oi! Oi!" "Mahgneeficant!" "Marvelous!"

"Cake, yohu're ahmazin'!" the eyepatched Knight cheered as she and the other Knights hopped onto Cake's back once more.

"Onward, Cake!" the one-armed Knight commanded.

Cake nodded and began to stretch forward. "C'mon, Fifi..."

Fionna watched her sister with worried eyes.

As the six girls continued to move, Cake began to look worse and worse. Her body was getting skinnier and skinnier, and she was getting a bit pale. She was breathing heavily, but the Corndog Knights just yelled at her to keep going. Fionna was starting to dislike them.

"Cupcake," Fionna said, "Maybe we should take a break for a w-AOH!"

Fionna exclaimed as she tripped over who-knows-what an face-planted into the ground. She sat up and looked at what she tripped over: something tubular, white, with coffee-colored patches, covered in fur. "Cupcake, that's you!"

"Gosh..." Cake said, rubbing the part of her body that was in front of her. She felt it on her body, but it felt like it was miles away. "I really should cheat more..."

"Vetřelci!"

Fionna and Cake gasped as they turned to their right. A female creature, part-human, part-spider, was hissing at them. From her waist down, the woman's body was like a spiders: a black abdomen, with four sinewy black legs poking out of it. The legs pricked at the ground, clicking against the ground as she crawled to move. From the waist up, the woman was still spider-like, but with a slightly human form. She had the waist, shoulders, and (kinda) head of a human, but that was just it: shape. Her skin was red, dotted with black, and four black, clawed arms protuded from her torso. Two sets of yellow eyes sat on top of each other. Her black lips were in the middle of two foot-long palps.

"SPIDERESS!"

Fionna unsheathed her sword and charged. The Spideress hissed, "Idiot holka!" and swung her two right arms at Fionna just as she came at her. Fionna was thrown against the wall, but it wasn't so hard as she thought it'd be. Confused, she turned around to see that the wall behind her was cracked and broken in a perfectly circular shape. "Cupcake! Hold her off while I open this cave!"

"Alright!"

Cake brushed off the Knights and stretched forward. As the lower half of her body was no longer functional, Cake could only dodge and weave as the Spideress clawed and bit at her, hissing, "Idiot kočkovité!", "Hloupý kočka!", and "Zabiju vás všechny ještě předtím, než se vidět ty přání!"

Fionna, meanwhile, hit the wall with her sword over and over. Each time, the cracks grew and dust bloomed, and little pebbles showered her knees. Finally, with a push of her shoulder, the wall caved in. Looking inside, Fionna saw a wide space with little to no light. Perfect. "CUPCAKE! NOW!"

Cake twisted to the left and flung herself at the Spideress. With a cry of "Můj dodatek!", the Spideress stumbled right into the cave. Cake was quick to cover up the entrance with her body.

With never-ending exclamations of, "Pusťte mě ven!" the Spideress sank her teeth palps into Cake's flesh repeatedly. The feline hissed in pain as venom shot into her bloodstream. "ARGH!"

"Cupcake, are you OK?" Fionna asked as she dashed over to the paling Cake.

"Aw, she's bonza, sheila." the scarfed Knight said as she and the others Knights climbed onto Cake's back again.

Fionna glared. "You don't know that."

"Cake's parfictly feine," the eyepatched Knight told the human girl. "Rite, Cake?"

"Yeah, I'm fine...Let's go."

With a deep breath, Cake stretched forward.

For the next hour, Cake stretched. She made bridges, moved boulders, pulled levers, pushed buttons, climbed stairs, cooked food, and spun wheels, all of which had to have at least some form of stretching. Her spine was aching, and her head was spinning, and her heartbeat was thin, but she said nothing. Fionna really wanted a Mammoth, and so help her, Fionna was getting a Mammoth!

The last puzzle (it seemed) was a crossword. A gigantic golden statue sat before them, holding the crossword in her hands. The entrance was her belly, and to the left of her, on the wall, there was the question bank:

1. A pathetic, lonely woman.

2. The best friend in Aaa.

3. A talking video game console.

4. A edible candy royal.

5. A bloodthirsty king.

Fionna nodded as she observed the puzzle. "Looks pretty easy. Hey, Cupcake, can you stretch up-AH!"

CAKE LOOKED TERRIBLE! Her white fur was grey, and her coffee fur was brown. Her eyeballs were the size of peas. Her lips jutted out madly. Her entire body was no wider than a baseball. She looked like death itself!

"...Yeah..." Cake's voice was barely a whisper.

"CUPCAKE, YOU LOOK AWFUL!"

"...No...just...can't...breathe..."

"Cupcake, no more Maze. We're gonna get out of here, return the Corndog Knights, go home, and eat a buttload of pasta."

"...Yeah...I'm...feeling...kinda...terrible..."

The Knights, however, had other plans. They whined and complained and shook their heads, jabbing Cake with their toothpicks.

"Nah, sheila, barrack!" "Yhou stritch gud!" "Thou must keep moving!"

"...Yeah...gotta...get...those...wishes..."

Fionna felt something nearly snap inside her angrily. Was it NOT obvious that Cake was in danger of dying? AND THEY WERE JUST PUSHING HER TO KEEP GOING! They were dancing on her last nerve.

"...I'm...gonna...do...it..."

"Cupcake, no!" Fionna snapped out of her thoughts just in time to fail at stopping Cake from stretching upwards. The feline reached over to the right side of the entrance, grabbing the six-foot-tall pencil and writing down the anwers.

1. Ice Queen.

2. Fifi

3. Beema

4. Prince Gumball

5. Marshall Lee

The crossword puzzle panel began to glow gold. There was a loud grinding sound, and the entrance rolled open. The Corndog Knights cheered like maniacs.

"Let's go, Cupcake!" Fionna shouted up to her sister.

As Cake stretched back down, the one Corndog Knight that had been silent the entire time hopped onto the puzzle panel. Fionna praised, "Great job. Now let's go get an Archaic Cerebral Velocipede Battle Mammoth!"

"...Gotta...move...carefully..." Cake rasped, her body becoming as thin as a golfball.

Meanwhile, the Silent Knight was still hanging onto the crossword puzzle. She accidentally lost her grip and she fell, smearing one of the words. 'Fifi' not spelled 'Fifl.'

And the gate closed, right down onto Cake's body.

Cake shrieked, falling to the ground. Fionna cried out and caught her thin sister in her hands, as the Knights complained as they fell to the ground.

"...I...can't...breathe...can't...go...on..."

"No! Barrack! Barrack! Barrack!"

"...I'll...do...it...if...you...cheer...me...on...in...Aussie..."

"Hang in there, Cupcake. I'll use my wish to save you."

"Welcome."

Fionna looked ahead. Down a tiled walkway, there was a pool of golden liquid. Silver lilypads floated on its surface, with glimmering blossoms cradled inside. As Fionna watched, a stone-skinned, lizard-like creature surfaced on a large lilypad, green, cat-like eyes blinking slyly. "Ssssssstep forward and recccccieve your wissssshesssss."

"Yes!" the one-armed Knight ran forward. "I shall wish for a new arm!"

The Knight stepped on a pink tile.

A giant anvil dropped out of nowhere, crushing the Knight flat.

The others gawked.

"Who'ssssssss nexxxxxt?"

"Nah, sheila," the scarfed Knight shook her head vigorously. "That floor's got traps."

"Cupcake gaht's ta streitch ous akroos." The eyepatched Knight agreed.

"Barrack!"

"...OK...I'll...stretch..." Cake tried to pick herself up, but she hardly twitched a paw.

"No! No more stretching for Cupcake!" Fionna glared at the Knights.

"But how else are we gonna get across, sheila?"

Fionna frowned. They really couldn't get across without Cake. The entire walkway was tiled, and she knew each tile held a trap. There was no other way.

"Cupcake, you have to stretch us across."

"...But...I...can't...move..."

"BARRACK! BARRACK! BARRACK!" Fionna cheered.

"BARRACK! BARRACK!" the Knights joined in.

"YEAH!"

Cake threw her six-feet-long arms around her sister's form, and her sister picked up the Knights. Cake began to stretch them over the walkway, getting skinnier and skinnier, more pained and weaker by the second.

"That's it, I'm out."

Just as they reached the other side, Cake collapsed. Her body was no wider than a large pushpin. She was deathly pale, and Fionna could barely make out a face. "Cupcake! Hold on! We can get our wishes now!"

"Yessssss. You may reccccccieve your wisssshesss. But be warned: there are no do-overssssss."

The lilypads in the pool glowed, and little glimmering spheres of unknown colors lifted up from the blossoms, into their paws and hands. It felt like solid liquid.

"OK," Fionna turned to the Knights, "You guys should wish for your friends to get better, right?"

"I wish for a bluey!" Immediately, a cattle-dog appeared next to the scarfed Knight.

"Ei weesh for ah laht of dhou!"

About a dozen does ran through the area, trampling the eyepatched Knight to clumps of batter and meat.

"Wow," Fionna observed, "You guys are really stupid."

"What do you mean?" the scarfed Knight inquired as the 'Bluey' bit off the lower half of her body.

"Cat, you are nexxxxxxt. What do you wissssssh?"

"Cupcake, wish for the Archaic Cerebral Velocipede Battle Mammoth! I'll use my wish to save you!"

"...Can't...think...on...an...empty...stomach...wish...I...had...some...pasta..."

Cake's wish disappeared with a small pop of color. Immediately, a bowl of peppered shrimp alfredo appeared next to her. Cake forced herself to reach over and scoop out a bite.

"CUPCAKE! YOU RUINED YOUR WISH!"

"I...know...sorry...You...should...wish...for...the...Mammoth..."

"But you hafta-"

"Do...it...for...me...!"

"I...wish for the Archaic Cerebral Velocipede Battle Mammoth!" Fionna's voice rose with excitement as she spoke.

"Yes...!"

"Your wisssssssh isssss granted."

And the Mammoth appeared in a flash of white.

It was a collosol brown mammoth wearing some kind of purple goggles on its face. It had a pink and purple tandem on top. It had eagle-like wings on its back, silver swords for tusks, and. A series of ladder steps ran up one of its legs, presumably for passengers to climb. It was the most amazing thing Fionna had ever seen.

"...Remember...it...has...to...choose...you..."

Fionna nodded and ran over to the mammoth. On sight of her, the mammoth began to buck and kick, and Fionn had to be very careful when she grabbed onto one of the ladder steps. Fionna forced her way to stand in front of the Mammoth.

And when they gazed into each other's eyes, Fionna felt a surge on energy.

Fionna the Human, what is it that thou wishest for?

I want my friends to be safe.

"I wish for what Fionna desires!"

There was a flash of white in Fionna's eyes. When she opened them, she saw a healthy, perfectly normal Cake and the four Knights on the Mammoth's back. Cake cheered, pumping a fist.

Ignisnobis snarled in rage. "NO! YOU WERE SSSSSUPPOSSSSSED TO PERISSSSH!"

"Who wants some pasta?" Cake asked the five girls around her.

The girls cheered in answer.

"C'MON, MAMMOTH!" Fionna commanded. "LET'S BLOW THIS POPSICLE STAND!"

TRIVIA

The Spideress was based on the Empress of Racnos, from Doctor Who.

Cake is revealed to have a limit on her stretching.

It is revealed that the Corndog Kingdom, or in some parts/all of Aaa, there is an Annual Firefly Harvest. What they do to the fireflies is unknown.
