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.
MYSTERY PLANE
Title Card
Fionna and Cake look through the windows of the plane, watching the figure that was approaching them from across the plane's wing.
Fionna snored softly in her sleep, burrowed in her deep green sleeping bag like a butterfly in a cocoon. Two furry paws slipped behind her ears, tying a neon green bandana over her eyes.
Cake, as silent as the wind, reached behind her, grabbed her blow-horn, and pressed down on the button.
HOOOOOOOOOOOOOOOOOOOOOONK!
Fionna shot straight up, ready and alert for any signs of danger. It only took her a half-second to become aware that she couldn't see. Everything was black. Panicked, Fionna called out, "Cupcake?"
"HAPPY BIRTHDAY, FIFI!" Cake screamed at the top of her lungs. She hovered in front of Fionna, tied to two dozen balloons-red, pink, yellow, green, orange, and purple. A bright blue ribbon was tied around her middle, like the bow of a birthday present.
"Cupcake?! Is that you?! I can't see anything!" Fionna cried, waving her arms around her like a madwoman.
Cake nodded. "Yeah, but that's only cos-"
"CUPCAKE! I'M BLIND! I'M BLIND ON MY BIRTHDAY!" Fionna screamed, clawing and waving her arms so wildly she nearly scratched Cake's side.
"Fifi, calm down sweetiebelle. You're blind-folded." Cake said, flicking the green bandana.
Fionna's fingers grazed her fingers over the neon materiel. "Oh. Rad."
Cake put a paw over the bandana. "Keep it on. I gotta surprise."
Ten minutes of blind dressing, three trips, and another dozen-and-a-half balloons later, Fionna and Cake were floating. Fionna, with no sight while floating through the air, began to grow motion-sick, but Cake instructed her to take short, quick breaths, and was fine. After about seven minutes, Fionna smelled cotton-candy trees, and knew that they had arrived in the Candy Kingdom. Soon, she felt and heard their balloons popping by contact with Cake's claws, and she could feel themselves sinking through the air.
"Three...two...one...touchdown!" Fionna's feet hit the grass, and Cake fell next to her.
Cake ripped off the bandana, and Fionna squinted in the sun as Cake cried, "SURPRISE!"
Fionna gasped. "A GREEN blindfold!" She snatched the bandana from Cake, staring at in in awe. "I never would have guessed!"
Cake smirked. "Fifi, the bandana isn't the surprise. THIS IS!" Cake span Fionna ninety degrees around, the human girl's Mary Janes making swirls of grass and mud in the Earth.
A plane. An actual PLANE.
It was 68 feet high, made of different metals all sewn together. Magically sewn, by warlocks. It was more tall than it was wide, and its wings were about a third of an average plane's height. Circular windows lined the surface, bright in the morning sun. It sat at the front of a long runway, ready for flight. Fionna had only seen planes in pictures, and now, seeing it in person, she was amazed.
"YOU. GOT. ME. A. PLANE?!" Fionna screeched. She grabbed her feline sister, pulling her into a bone-crushing hug (she heard bones pop.) "I. LOVE. YOU. SO. MUCH!"
"Tha...plaine...izn't...tha...sooprize..." Cake gasped, her lungs failing her.
Fionna stopped hugging. "What?"
"We have to ride the plane to get to the surprise." Cake explained.
"Oh," still smiling, Fionna let go of her sister. "Almost as cool as getting an actual plane."
Cake chuckled. "I'm going to get our tickets." Cake began to head over to the airport building, which wasn't very big at all. There was one airport building for every plane, and now, the building was only about the size of a car-wash. It consisted of very little: a front desk, a metal scanner, a search station, and a shuttle.
Fionna watched as her sister walked away, until another figure caught her eye. A blue-skinned woman (with hair the same color as her skin) wearing a simple white blouse and slacks-a pilot uniform-was walking by, heading towards the airport building. The Pilot.
"Hey, Miss Pilot-Lady!" Fionna called. "It's my birthday!"
The pilot turned to Fionna, and the human saw that her right eye was nonexistent. "Oh, so you'll be riding my plane today? I'm looking forward to it."
And, cackling, the Pilot touched the plane, opened a hatch, and disappeared in its confines.
A robotic voice boomed from the airport building. "Now boarding."
"Fifi, come on!" Cake called, waving for her sister through the front doors.
Fionna watched as the Candy Kingdom began to fly by, disappearing into clouds. A voice announced that 'You are now free to move about the cabin' and passengers began to stand from their seats.
Their cabin was one of the coolest things Fionna had ever seen. There were three long columns of seats. The seats came in booths, with four to each one. Each booth had their own televisions, video game systems, blankets and pillows, and menus for food. You could even raise walls for privacy. And if you needed anything, all you had to do was press a button for the stewards/stewardesses. The cushions they sat on were red velvet, and the seats were framed with mahogany. Each booth was different, in size and color. They had a both next to a window. Overhead, a net of rope covered the entire ceiling, with luggage packed inside.
"This is the best birthday ever!" Fionna giggled-something she rarely did.
Cake chuckled. "I'm going to go get something to read." She stepped out of her booth and disappeared through the purple curtains at the end of the cabin.
Suddenly, the plane shook violently. Fionna, who had never been on a plane before, felt her heart jump and her breath hitch, even though it stopped after only a moment. Behind her, she heard a smack and a "I am so sorry!" Turning around, she saw a tall candy cane woman and a gray-haired candy corn mistress. Apparently, the candy cane woman had accidentally slapped the mistress with her head.
"It's alright." The Candy Corn Mistress chuckled. "Just don't let it happen again."
There was a beeping, and the Pilot's voice rang out. "Attention all passengers. We're now heading higher into the atmosphere, and we will be getting a little turbine-rickety. Please fasten your seat-belts."
Fionna buckled her seat-belt, and her eyebrows furrowed when the Pilot chuckled mysteriously.
"Found some brochures," Cake said, holding up three brochures for Ignoramus Island, Mount Murchin, and Vandill Valley as she approached their booth.
"Good," said Fionna, "Now find your seat-belt."
Just as Cake's seat-belt clicked, the plane shook violently once again. Behind them, Ms. Candy Cane accidentally hit Mistress Candy Corn repeatedly, hitting the back and front of her head over and over. "Sorry! Sorry! Oh, I am so sorry!"
The plane stopped shaking. Ms. Candy Cane looked ashamed with herself. "Mistress Candy Corn, I am SO, SO sorry."
This time, Mistress Candy Corn didn't reply.
Fionna looked out of the porthole and saw a flock of brightly-colored, dinosaur-like birds. "Cupcake, look! A flock of Atmokeets!"
"Ooh! I wanna see!" Ms. Candy Cane cried excitedly.
But just as she turned to look out of their porthole, she smacked Mistress Candy Corn in the back of the head.
Mistress Candy Corn snapped.
"I'M GONNA KILL YOU!"
At that exact moment, the lights in the plane went out, and there was an odd, grinding sound.
And when the lights came back on, Ms. Candy Cane was nothing more than a pile of bones and organs.
Chaos broke out. Mistress Candy Corn screamed like a banshee, and ran from her seat, falling onto the floor. The fellow passengers in the cabin gawked, screamed, and jumped at the sight of the corpse, and panicked whispers filled the cabin.
"A dead bod?" Fionna asked, and poked Ms. Candy Cane's corpse. Her hat fell to the floor.
Someone must have pushed their booth's button, because a cream-puff stewardess approached the corpse, wearing a bright pink blazer and skirt.
Fionna was the first to speak. "Is she gonna be OK?"
The Stewardess gave her a perplexing look. "She's already dead."
"Hey, Fifi, this looks bad," Cake tugged on her sister's skirt. "Maybe we should I should just form a parachute and get us to the ground so we can walk to your surprise."
"Are you serious?" Fionna's face broke into a huge, excited grin, and she gripped her bunny-ears in glee. "IT'S A MURDER MYSTERY! ON A PLANE! WE GOTTA SOLVE IT!"
Cake sighed, but smiled. "Oooooookay."
Fionna turned back to the stewardess, who was examining the corpse. "Any clues?"
The Stewardess paused before turning to the human girl. "I believe it was the woman who screamed 'I'm gonna kill you'."
Murmurs of agreement filled the cabin.
"N-no! NO!" Mistress Candy Corn sputtered. "It w-wasn't me! I-I-I swear!"
"Everyone! Calm yourselves!" Fionna yelled above the murmurs, and stood next to Mistress Candy Corn defensively. "It wasn't Mistress Candy Corn."
"Oh," Mistress Candy Corn smiled, "Thank you so much."
"No," Fionna shook her head, "It's never the first person you expect. Ever."
A little pink marshmallow spoke up. "So who do you think it is?"
In answer, Fionna turned back to the Mistress. "Mistress CC, do you have any enemies on this train?"
The Mistress paused, thinking for a long moment before answering, "I do have one enemy. And his-or-her name is..."
The lights went out.
There was a grinding sound.
The lights came back on.
Mistress Candy Corn was nothing more but bone and intestine, with a finger still pointed upward.
More gasps, screams, and whispered filled the cabin.
"See?" Fionna sighed. "The Mistress wasn't the Aviator."
"Aviator?" inquired Cake.
"Yeah, cause we're on a plane. All killers have creepy-cool names. But now we need to discover who the Mistress's enemy is. It could be anyone on this train." She said the last part to Cake.
Behind her, a green gumdrop girl, pointed out, "It could even be you."
Fionna glanced at Cake before turning to the gumdrop girl. "Yes, it could. Except I didn't do it."
"But we don't know that," the gumdrop girl pointed out.
"I bet you're framing me for taking suspicion off yourself." Fionna announced. "Are you Mistress Candy Corn's enemy, AND the Aviator?"
The gumdrop girl jumped. "What? NO! I didn't even KNOW her!"
Fionna pointed a finger at the gumdrop girl, turning to the other passengers. "Soupçonne le numéro un!"
The lights went out.
The grinding sound screeched.
The lights came back on.
And the gumdrop girl's corpse sat in its seat.
Fionna let out a gasp of surprise before turning to Cake. "Snake-snares! I really thought I had something there."
"Fifi, I know this is gonna sound weird," Cake started, "But what about the Pilot?"
Fionna paused. The Pilot, who always laughed mysteriously when she spoke. The Pilot, who always looked at Fionna like she was hiding something. The Pilot, who was, altogether, suspiciously mysterious.
"Nah, it's not her."
Cake frowned. "Oh. Why not?"
"Because she's mysteriously creepy. And that makes it too obvious."
"Whatevas." Cake sighed, and sat down in her seat. "I'mma reading some brochures." She lifted up the Ignoramus Island brochure, her face hidden behind its colorful cover.
"We're running out of suspects," Fionna thought aloud, "And we're running out of time. The Aviator could attack at any-"
"Attention, passengers."
The curtain at the end of the cabin pushed open, and the Pilot sped into view, dashing in on a pair of roller skates. She jumped in the air, clicked its heels, and landed perfectly. "Rad. Yeah, it's me. The Pilot." She paused, cackling a moment. "I couldn't help but over someone saying I was mysteriously creepy. But just so you know, I am not mysteriously creepy. I'm perfectly amazing."
She cackled again. Fionna and the Stewardess exchanged glances.
Just before she disappeared behind the curtain, the Pilot turned around. "Happy birthday, Fionna."
And she left.
Fionna leaned over to Cake. "Cupcake?"
"Yeah?" Cake looked up from her brochure, smiling.
"The Pilot was just here, and she was even more mysteriously creepy than before."
Cake frowned, and shook her head. "No way! She was perfectly amazing!"
Fionna stared at her sister a moment. "...Anyway, she still isn't the Aviator." She turned to the passengers, her hands behind her back. "The Aviator is right here among us. Isn't that right...Stewardess?"
The Stewardess turned around, expecting another flight attendant such as herself, but found no one and turned to Fionna once more. "You...think it was me?"
"When Ms. Candy Cane died, you diverted any suspicion to yourself by accusing Mistress Candy Corn. Then you murdered her, to protect your alibi."
"...Are you serious?"
"Fifi," Cake walked over and tugged her sister's sock. "I think you're waaaaaay off course."
"I believe I am way ON course."
Before Fionna even finished, the lights flickered off. And with the grinding noise, they flickered back on.
The stale white corpse of the Stewardess stared at Fionna, unmoving and lifeless.
Fionna cried out words of rage.
VERY SEVERE words of rage.
So severe that I don't think it appropriate to tell you these words.
As the Stewardess's corpse collapsed to the floor, Fionna turned to Cake. "My gut-feelings aren't getting me ANYWHERE! I can sense the Aviator laughing at us. We need HARD EVIDENCE."
Fionna walked through another cabin, peering inside all of the booths and its passengers and luggage. She stopped at a solid-gold booth with silver seat-cushions. "Aha!"
She reached inside a large basket, and pulled out its items. "Some bacon, chicken, and lettuce."
Next, they went to the galley. They opened every cabinet and opened every freezer, until finally, Fionna reached inside a drawer and pulled out a slip of paper. "A list of passengers. From ANOTHER PLANE!"
They went to the lower-class cabin, digging through all of the luggage overhead. Fionna pulled out a thick, leather-bound book. "Cupcake! It's a glossary!"
More searching through the luggage, and Fionna held up some paper sheets. "Morse Code."
Even after gathering all of the evidence, setting up a dry-erase board, and covering it from head to toe in calculations, notes, and blueprints, Fionna was stumped. "This isn't making any sense!"
"Me neither!" Cake sighed, waving her pointing-stick around like a fairy wand. "Maybe the Aviator is just too sly for us."
Fionna gasped. "THAT'S IT! Cupcake, gather everyone in the cargo hold, and I'll reveal the Aviator's identity."
"You are all the remaining survivors/suspects," Fionna told the group of passengers as they stood in the cargo hold of the plane which turned out to be unpleasant and uncomfortable, as rats and water were everywhere, and all of the luggage made it a tight squeeze). "So that means tha one of you is the Aviator."
The passengers gasped. Murmurs of confusion floated in the air.
"Let me explain my conclusion," Fionna told them. "I saw Papaya Girl skimming through her clarinet sheet music." As she continued, Papaya Girl shook her head frantically. "Sheet music that made up a song very special to Lollipop Guy." Lollipop Guy jumped in surprise. "A song that reminds him of Ice Cream Girl." Ice Cream Girl blushed. "Before Mistress Candy Corn died, Doctor Sundae was in possession of a basket of bacon, chicken, and lettuce." Doctor Sundae froze. "And you, Papaya Girl, have lettuce leaves on your shoes!" Papaya Girl looked down at her lettuce-covered feet. "And you, Chocolate-Chip Girl." Chocolate-Chip Girl jumped as everyone turned to her. "You were in possession of this glossary." Fionna held up the book. "A glossary that just-so-happens to have these highlighted words:" she held up the book, calling out the words that were marked.

The passengers gasped.
"But the true Aviator is someone who no one would have suspected," Fionna grinned, excited to finally reveal the culprit. "The real Aviator is..."
The lights went out, and Fionna's voice was drowned out by a terrible, all-too-familar grinding noise.
She didn't even have to look at the passengers to know that they were all dead, only piles of bones and intestines. "Cupcake, if it wasn't me, and it wasn't you, and all of the passengers are dead, who was the Aviator?"
"There's still the Pilot," offered Cake.
"Oh, yeah..." Fionna paused for a long moment. "...It was her."
Cake gave a weak cheer. "Wohoo! You solved it!"
"I knew it was her all along," Fionna half-declared, half-teased. "Because she's mysteriously creepy."
Cake's tail puffed out in sour disbelief. "WHAT? I WAS TELLING YOU THAT THIS WHOLE TIME!" She turned her back to her sister, crossing her furry arms over her puffed-out chest, "The nerve you have! Hmph!"
"I know," Fionna ruffled her sister's ears, "I couldn't have done it without ya!" Once again, Fionna pulled her sister into a bone-crushing hug. "We make good sleuths!"
Fionna was so focused on hugging her sister as hard as possible that she didn't even notice the lights flickering, or the soft grinding noise. As she began to hug her sister, however, she did notice that her fur felt smooth, but gritty.
Fionna opened her eyes, and let out a scream so shrill and loud that her ears rang for a moment.
Cake. Cake, who had been smiling and laughing just seconds ago, now lay in a crumpled heap on the ground, no fur, no skin, no eyes, and no tail. She was nothing more but brittle bones and sloppy intestines.
Fionna felt pressure behind her eyes. Her nose began to feel fuzzy, and her throat burned like crazy. Fionna, the greatest heroine in Aaa and probably the most tomboyish girl for miles around, was crying. Not that she had never cried before. She had cried plenty of times before. In fact, people used to call her a crybaby before she made it her duty to protect all of Aaa. But now, Cake...her sister...was DEAD. It reminded her of when Julia and Michael, her and Cake's parents, had died. She cried so hard that she was in not only mental pain, but physical pain. Cake had left a few months prior, saying that she was going to explore the world. You wouldn't have guessed it, but Cake and Fionna hadn't gotten along as children. Cake had returned home for the funeral (it took a while, as she had to escape from some crazy ice-witch who would later be known as the Ice Queen) but she made it. And she had approached Fionna, took her hand, smiled, and said, "It's alright, Fifi. Cupcake's gotcha." And ever since, they had been thick as thieves, always calling each other 'Fifi' and 'Cupcake.'
And now, with Cake dead and gone, Fionna felt like she was the only person in the world.
Fionna took her sister's corpse in her arms, threw her head back, and screamed, her throat tearing and her eyes spilling out tears, "NOOOOOOOOOOOOOOOOOOOOOOOOOOO OOOOOOOOOO!"
Someone cackled.
Fionna span around, tears splattering the floor, to see the Pilot smiling evilly at her.
Fionna had never felt such rage. She was even more furious than the time she thought Marshall Lee killed Cake. She felt like she was going to erupt like a fiery volcano. "HOW COULD YOU MURDER ALL THESE PEOPLE?! HOW COULD YOU MURDER CUPCAKE?! ON MY BIRTHDAY!" That last part sounded a tad bit conceited, but Fionna was too enraged to care.
"Don't feel so bad," the Pilot cooed. "I got you a birthday present." the Pilot held up a thick, razor-sharp, curved blade. Fionna knew all too good that it wasn't for her to take.
Fionna looked down at Cake's corpse and set it down gingerly. She reached into her backpack, ripped out her ruby sword, and let out a fierce battle cry full of agony and rage.
The Pilot dashed away on her roller skates. And Fionna followed.
They came to the lower-class level of the plane. The Pilot was already at the opposite exit by the time Fionna stepped through the curtain. The Pilot grabbed an abandoned food cart and pushed it so hard that it came flying down the aisle, straight for Fionna. The human girl acted quickly. She took her ruby sword and sliced it down the middle with so much force that it split in half. Food splayed everywhere.
Fionna ran up to the middle-class level, where Fionna and...Cake had sat earlier. The Pilot, already skating ten feet away, acted quickly. She sliced the net of rope on the ceiling. A landslide of luggage rained down on them. Fionna didn't waste time. She sliced through the luggage, items raining down on the floor, chasing after the Pilot like a madwoman.
When they reached the top level, the first-class level, the Pilot didn't do anything to slow her down. She sped right into the cockpit of the plane. She didn't even have time to lock the door before Fionna burst in, kicked her square in the chest, and sent her flying.
The Pilot stood up again quickly. She and Fionna slashed their blades at each other. Or rather, Fionna slashed while the Pilot blocked her attacks. Fionna missed the Pilot and accidentally impaled the controls of the plane. Sparks flew everywhere, but whatever controls Fionna hit weren't important at the time, because the plane only shook slightly.
"MY BIRTHDAY WISH IS REVENGE!" Fionna cried as she hit the Pilot's blade with her ruby sword, sending it flying straight into the wall. Fionna raised her sword above the head, ready to finish it. "HAPPY BIRTHDAY TO ME!"
"WAIT, NO!"
Fionna hesitated, but she didn't know why. The Pilot began to mold and waver. Fionna was just about to bring down her sword, as she thought the Pilot was using some kind of magic to escape, but the Pilot stopped molding, instead showing her true form:
CAKE?!
Fionna was so overcome with shock and joy (and a little pinch of anger because Cake had made her feel so horrible) that she chucked her sword at the plane's controls. "YOU'RE ALIVE!" She grabbed her breathing, living, blue-white-and-gray-covered sister. She pulled back to look at her, and Cake licked off all the color from her fur, which appeared to be made out of icing. "YOU WERE THE PILOT THE WHOLE TIME?!"
"Yep!" Cake nodded. "You were so busy with the murder that you never even noticed."
Cake looked over her Ignoramus Island brochure, hearing and seeing Fionna talking to herself about the Aviator and the suspects. She molded her face so that it hung onto her body with only a cord. She led her face behind the curtain, where two candy woman quickly covered her in icing so expertly that her clothes and skin looked completely real. Then she stepped out from the curtains. "Attention, passengers..."
"The corpses were the hardest part."
Ms. Candy Cane, alive and not dead, moved like lightning. She opened the hatch beneath her feet, taking the faux corpse of herself from TreeTrunks. She handed it to Mistress Candy Corn and leaped down the hatch. Mistress Candy Corn finished setting up the fake corpse just as the lights came back on. She screamed.
"It was all part of your birthday present." Cake finished.
"So nobody was murdered?" clarified Fionna.
"Nope." Cake shook her head. "Unless you count the plane's controls." She pointed at the control panel, which had caught fire.
They had just started laughing when a orange light began to flash and the plane began to shake. Softly at first, then roughly, then madly.
And then they were falling from the sky.
Fionna and Cake screamed like banshees as their stomachs were thrown into their spines and they nearly flew off their feet. Through the giant glass shield, the clouds disappeared as they dived nose-first for the Earth. The ground grew closer and closer, as if they were zooming in on a digital map.
They braced for fatal impact.
But it never came.
Instead, they bounced on their feet for a moment. They could roughly make out the sounds of muffled cheering. When they opened their eyes, the entire glass shield was covered in thick red...Jell-O?
Fionna and Cake's screaming grew softer and softer. "AAAAAAAAAAAAAAAAAAAAAAAAAAaa aaaaaaand we're OK."
As it turned out, the plane had fallen right into Jellaine, the 80-feet wide mass of walking Jell-O. When Fionna and Cake stepped out through the emergency hat, all of Fionna's friends, from the candy citizens to the roughhousing women, screamed, "HAPPY BIRTHDAY, FIONNA!"
"...tooooo youuuu!" Everyone finished. The cake, which was a life-sized sculpture of Fionna holding up her ruby sword as she stood on a pile of gold and jewels, was immediately cut. It was Fionna's favorite, red velvet with a hazelnut cream filling. Fionna turned to Cake as she picked up her fork, "This is the best birthday ever. Thanks, Cupcake."
"No problem, Fifi," Cake said, and Fionna grinned inside and out. "We all agree you deserve it for being a great heroine."
Fionna smiled as she cut off a chunk of cake. "I think my favorite part was when we landed on Jellaine. That must have taken forever to plan."
"Hm? Oh, no, that was a total accident," Cake said through a mouthful of red velvet and hazelnut cream. "That was a total accident. We could have sworn that we filled the plane with enough gas until we landed."
Fionna stopped chewing, and glanced behind her at a long runway (for the plane) she hadn't noticed before. "But I thought the plane crashed because we hacked the controls?"
Cake shook her head, "Prince Gumball was doing the real controls on a remote." She pointed at Prince Gumball, who still had the remote controller in his hands. "He says we ran out of gas while we were up there."
Fionna looked back at the plane, which was still stuck in Jellaine. If the plane wasn't supposed to crash, why did it? Who or what caused the fuel to disappear? What were the odds that she and Cake landed in Jellaine just in time?
There are some mysteries in this world we may never solve.
TRIVIA
There are multiple clues throughout the episode that hint at the truth:
1. The Pilot enters the cabin to wish Fionna "Happy birthday"; however, the Pilot should not have known Fionna's name.
2. Each time a passenger is murdered, the Candy People only screamed and gasped, but in "Slumber Party Panic," candy people would explode.
3. Cake is only in the same room as the Pilot once: when Cake's face is hidden behind the brochure
4. The Pilot says that he heard someone say she was mysteriously creepy, but Fionna only told Cake.
5. When the Pilot enters the passenger car on roller-blades, she states that she's "perfectly amazing." Once he leaves, Fionna disagrees, but Cake hastily replies, "No way! She was perfectly amazing!"
