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

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.

Marshal Lee—is a counterpart of Marceline. He has the same abilities as Marceline. Marshall Lee has pointy ears and light blue skin. His hair is shorter than Marceline's but he has a matching permanent bite mark. He initially wore a grey plaid shirt, but now wears a red and black plaid shirt. He also wears dark blue jeans, and brownish-white sneakers. His outfits differ in the episodes, though, like Prince Gumball. Though Marceline has circle-shaped eyes, his eyes are rectangular. Unlike Marceline's forked, snake-like tongue, Marshall Lee's tongue is rounded. Marshall Lee is a wild rock star. Centuries of wandering the Land of Aaa have made him a fearless daredevil. He and Marceline both have regular electric bass guitars.

Title Card

Fionna looks up at Prince Gumball as he sits before his window longingly.

Fionna and Cake sat on their checkered blanket, watching the sun sink into the horizon. Cake smiled and turned to her sister as she peeled off an orange. "Hey, it's Couples Only movie night. We're watching Cold Spirits. Who are you bringing?"

Fionna thought hard for a moment before shrugging. "I'm not sure. Who're you bringing?"

"My boyfriend, duh," Cake smirked, her furry forehead crinkled in amusement.

"Oh." Fionna paused before something small to her left caught her eye. She turned and saw a little slug crawling over their blanket. Smiling, she picked it up. "I'll take this snail."

Cake chuckled and shook her head. "It's COUPLES' ONLY. You gotta take someone you can smooch."

Fionna hesitated, looking down at her feet. "I don't really want to BE smooched..."

"You don't HAVE to smooch. You just have to bring someone you CAN smooch."

Fionna looked down at the slug. When she bent down with her lips puckers, it slug-smacked her and disappeared into thin air. Fionna sighed and looked down at an apple. Smiling, she said, "I'll take this apple!" She reached into her pack, pulled out a marker, drew a sloppy face on the apple, and kissed it.

Cake sighed. "Fifi, put the apple down. It's time I explain a few things about couples to you.

"So do you know who you're gonna call?" Cake asked an hour later.

Fionna nodded as she turned the dial on her transceiver, watching as PG showed up on the little screen. "Yeah. I'm taking a guy I don't have to smooch."

She put the headphones over her ears, fixing the little microphone in front of her mouth.

"Hello?"

"Hi, Prince Gumball. I was wondering if you'd want to go to Couples' Only movie night with me."

"Hm. Sounds romantic."

"W-NO! Nonononono! I was just...uh-" Fionna's face went rosy pink.

"I'd really like to, Fionna, but I have to practice for the Egg-Tossing Championship at Battle Kingdom tomorrow."

"But-"

"Au revoir, Fionna."

The prince hung up.

Fionna glowered at the ground. "He can't go."

"Yeah, he can!" Cake took the transceiver, fitting it over her pointed ears. "We just need him to realize that he needs to focus on his love life more than his princely duties."

"WE DON'T HAVE A LOV-"

"I'm calling Marshall Lee."

Fionna froze in surprise and confusion. "But I thought you were-"

"Terrified?" Cake finished. "Yeah, I was for a while. But after reading The Afterglow Chronicles, I've discovered that I just don't understand Marshall Lee.

"Alo?"

"How-dee-doodle, it's Cake. Listen, we need to make Prince Gumball jealous so he'll go with Fionna to Couples' Only movie night."

No reply.

"Marshall Lee?"

HISSSSS!

Cake screamed like a madwoman, her back arching, as Marshall Lee hissed from behind her.

Fionna chuckled. She had watched as Marshall Lee crawled from underneath the floorboards, over to Cake, and hissed at her like a snake. "So you'll help us, right?"

"Yeah, I'll help." Marshall Lee said, drifting over to sit next to Fionna. He looked different from the last time Fionna'd seen him. Half his head was shaven off, like he'd taken an electric razor and sheared it off. He wore a loose gray tank and ripped black jeans, as well as deep purple sneakers. "I'll be hilarious."

"OK, here's the plane," Cake whispered as they sat at the base of Prince Gumball's tower. The night was a deep purple, the half-moon orange overhead. "Fionna says something, and you both start laughing WAY LOUD. Then Gumball-" she pointed up at the window, where Prince Gumball's shadow could be seen moving. "-Gets jealous of you." She pointed at Marshall Lee. "Thus awakening his true love for Fifi!"

Cake stepped behind a nearby cotton candy tree.

Fionna turned to Marshall Lee. "Funny. Something funny...uh...whaddup?"

Marshall Lee burst into laughter. It sounded ninety-percent fake, but she could make out a glimmer of actual mirth.

"Upsy-Daisey?"

More laughter.

"Flapjacks?"

Marshall Lee laughed as loud as he could.

"Ahem."

Marshall Lee's laughter silenced as they lookd up. Prince Gumball was smiling down at them. In the dull light, Fionna could make out a blue tuxedo he was wearing. "Hello, Fionna." He frowned heavily when he turned to Marshall Lee. "Hey, Marshall Lee."

"Hellooooooooo, Bubba." Marshall Lee sang, twiddling his fingers at the candy prince.

Prince Gumball grunted, which Fionna guessed was guy-language for 'whatever.' "So, what's so funny, Fionna?"

Fionna felt like someone, somewhere, was laughing at her. She really should have put more thought into what she said. "It's...uh...it's a...um...thing."

Prince Gumball stared at her a moment, confusion on his face. "Alright...Well, hey, keep it down, I gotta practice my egg-tossing." He turned away, mumbling something under his breath about 'jerks' and 'womanizers.'

"Excellent work!" Cake appeared before them with one stretched stride. "Time for phase two in Operation: Fioball. Wait here." Giggling, Cake fluttered away.

Marshall Lee sighed. "Hey, listen, Fionna, I know Cake's your sister and all, but if you really want Bubba to go out with you, you're going to have to stop listening to the cat and start listening to an actual guy."

"But Cupcake said phase two is going to be a smashdown."

Marshall Lee scoffed and tossed his head, flinging his half-bangs out of his eyes. "How's Cake going to know what a guy wants?"

Fionna bit her lip, brushing her blond bangs out of her green-blue eyes. "Yeah, I guess you do have a point."

"Excellent." Marshall Lee began to float, his face in a deep, thoughtful frown. "What we need now is something...cool. Guys love cool more than anything. Cool-cool-cool. If you can show Bubba that you're cool, he'll definitely wanna go to the movies with you."

Fionna's cheeks went orange-pink. "You said cool so much, it sounds all weird now. Keeeeeeeewl."

Fionna felt a hand on her shoulder. Surprised, she turned around and saw Marshall Lee smiling at her. "So what are some cool things you like to do?"

"I usually go hunt down monsters with Cupcake and slay them with my ruby sword. Either that, or I go hunting for treasure!" Fionna cut her sentence off, tugging on her hair in embarrassment. "But dudes just think that's weird."

"Nah-nah," Marshall Lee assured her. "That's totally cool. You just gotta do a bit of that." Without another word, Marshall Lee floated past.

Fionna was about to follow him when Cake's words of "Where are ya goin'?" sounded off behind her. Cake was holding a bundle of what looked like red-and-orange clothes and a harp. She held up the items. "Check it out!"

Fionna's blond eyebrows furrowed. "What is that stuff?"

"It's a duchess gown!"

Fionna felt like her stomach gagged. She HATED dresses, especially gowns.

"Guys love seeing their lady in a gown! Trust me!" Cake dragged her sister inside a nearby wash-house.

Needless to say, Fionna despised the duchess gown.

It was red, gold, and orange, as she'd predicted. The gown consisted of a simple orange dress covered in a red dress that split all the way down the front and had two long, loose sleeves that almost went past her wrists. Gold threads wound up the back of the orange dress, and the red outer-dress was covered in exquisite gold designs. The dress covered her Mary Janes, and she had a halo of holly on her head. Cake had tried to pry off her bunny-hat, but Fionna had kept it on. The harp was heavier than she thought, but she was fine.

"Fionna!"

Marshall Lee floated in front of her, confusion and surprise (and maybe a bit of awe?) on his face. "What are you wearing? You look...so..."

"AMAZING!" Cake finished for him. She had molded herself into a love seat, with her legs as the pegs and her body as the cushions.

"Well, I guess, but it's going to mess up the plan," Marshall Lee frowned.

"What choo talkin' bout?"

"Uh, well..." Fionna cleared her throat awkwardly, pricking at her harp. "I was just thinking, maybe, you know, we ought to give Marshall Lee's idea a shot, too."

Marshall Lee smiled widely, fangs glinting, but Cake looked appalled. "His idea?" She seethed when Marshall Lee stuck his tongue out at her. "What's wrong with my idea?"

Nothing else could be said. At that moment, a sound rang throughout the hallway. Prince Gumball's humming. Cake molded back into position as Marshall Lee quickly formed into a bat, flying up to hide in the rafters. Fionna was alone.

Prince Gumball rounded the corner. As Fionna had thought, he was wearing a bright blue tuxedo, complete with a bow tie, jacket, vest, slacks, and what looked like tap shoes. When he saw Fionna, he smiled widely. "Oh, hey, Fionna, did you ever find some-?" He cut off short. His eyes went wide as he stared at Fionna a moment, and when he spoke, he was smiling, with a hint of laughter in his voice. "What are you wearing?" He flicked a holly leaf on her halo.

"This is my...duchess gown."

Fionna felt beads of sweat begin to build beneath her skin. She risked a glance over at Cake. Cake knew she needed help, and the mold of a harp appeared in her fur.

"This is my...duuuuuuchess goooooown~!" Fionna sang, her cheeks blushing pink as she played a few soft notes on her harp. She was actually pretty good.

Prince Gumball burst into laughter. Fionna hesitated, wondering if he was laughing to offend her or to compliment her.

She heard a small 'psst' sound. Looking up, she saw Marshall Lee, as a bat, hiding in a space between the rafters. He made a few movements with his hands and arms. It took Fionna a moment before realizing he was making SWORD movements.

"So..." Fionna hesitated, setting down her harp. Prince Gumball was all ears.

Fionna reached into her bunny hat and took out her retractable ruby sword. It sprung to full length in her hands, and with a war cry, she raised it above her head.

Prince Gumball screamed.

Four guards, two doors, and one great big misunderstanding later, Fionna was tossed stomach-first onto the sweet-smelling ground. She groaned as she turned over, sitting up. Dirt caked the front of her dress, and her halo was broken, holly and berries scattered everywhere. Her harp had plucked a few strings, too. A little line of red was flicked across her wrist.

Cake hopped out of Fionna's hat, groaning in dizziness as she grew to normal size. Bat-Marshall Lee swooped over and landed next to Fionna. In just a second, he had morphed into his regular form, frowning in concern. "That gown was a bad idea."

Every hair on Cake's body twitched in unison. "Bad id-" She sprung to her paws, ears sharp and muzzle scrunch. "BAD IDEA? Fifi, can you believe the nerve of this guy?"

Fionna scratched the back of her neck through the fabric of her hat. "I...suppose the gown did feel a little...goofy."

At first, Cake's tail just puffed out like a gigantic feather. Then, scowling, she clenched her paws into fists and spat, "Well, fine! You can just give it back, then."

Fionna began to pull the dress over her head, her voice muffled as she said, "I'm sorry."

"Good luck getting into that movie without my help," Cake sniffed. She took the filthy gown, the broken halo, and the demolished harp before stretching away, out of sight.

"What a drama-queen," Marshall Lee sighed, running his hand through the buzzed-off half of his head.

Fionna shook her head. "Nah, she just needs some pasta."

"Well, alright. I've got another idea." Marshall Lee smirked.

"What is it?"

"The only thing guys love more than cool is MANLY. Guys want girls who can make their blood pound and their muscles scream. They need to...to...BE ATTACKED BY MONSTERS!"

Fionna paused. "Metaphorically?"

Marshall Lee chuckled once and held out a hand. Fionna took it. Despite what The Afterglow Chronicles said about vampires being really warm and rigid, Marshall Lee's touch was cool and smooth. He helped Fionna to her feet and said, "I'll show you what guys like. Hold on tight."

He pulled Fionna against him, wrapping her left arm around his middle, wrapping the other around his shoulder. His tank-top smelled like must and mist, and despite his lanky appearance, Fionna could feel some muscles in his pale arms. Fionna blushed. Prince Gumball and Marshall Lee were the only two guys in Aaa who could make her blush. Sure, she blushed when she was embarrassed and stuff, but on boy-level, there was just their royal highnesses.

"Ready?" Marshall Lee asked.

"Urm..." Fionna held on tighter, putting her Mary Janes over his converse. "Yeah...?"

With a 'wahoo!', Marshall Lee took them to the skies.

When they began to land, it was in the middle of a pack of trolls. Ten-foot tall, weapon-bearing trolls. When they saw them, they let out horrible howls and ran. Trolls HATED vampires. Marshall Lee let out a battle cry, and looked at Fionna expectantly. Fionna let out a battle cry of her own.

They ran after the trolls. When they got in the middle of the pack, Marshall Lee grabbed Fionna and tossed her onto the leading troll before jumping onto the one next to it. They drove the trolls all the way back to the Candy Kingdom.

"Quietly...quietly..." Marshall Lee whispered as he ushered the last troll through the doorway. He silently closed the door. "Alright. This shouldn't take long." Morphing into a bat, he turned to Fionna. "Don't mess this up, OK?"

Fionna chuckled and waved him goodbye as he went to hide in the rafters once more. "Alright."

At that exact moment, Prince Gumball burst through his bedroom door, screaming. His white-and-pink-polka-dotted pajamas were torn in some places, and his top button was broken. He scurried to push the door close behind him, fighting against the snarling, punching trolls. Panting, he turned to Fionna. "Oh, Fionna! I'm so glad you're here! There are TROLLS in my room!"

"Yeah, I know! I put them there! Pretty manly, huh?"

Ten minutes later, Fionna was being dragged out of the castle by the Banana Guards. They let her go and walked back to the castle gates, where Prince Gumball was looking at Fionna with a sad stare. "I'm sorry, Fionna. But until you stop acting like a maniac, you are forbidden from entering the Candy Kingdom. Good night."

The prince walked back inside, the licorice gates closing shut behind him.

Fionna groaned and smacked let her head rest on the dirt.

"I don't understand, Marshall Lee," Fionna sighed as he and the Vampire King sat in the Attic of the Treehouse. It was cool up there, and nothing changed since Fionna and Cake had last been there, when Cake's imagination went out of control. Fionna closed her eyes heavily. "I guess he just doesn't like me the way I like him."

Something cool and slender pressed her lips. She opened her eyes to see Marshall Lee pressing his finger against her mouth. "No more talk like that. I mean, come on, a bloke like Bubba? You'd be bored within a day." He flashed Fionna a fanged smile. "And I, for one, think you're pretty awesome."

He leaned in and kissed Fionna on the cheek. Fionna felt her cheeks flame. When he pulled back, the spot where he kissed her skin was still cool. Marshall Lee stepped over to the exit of the Attic and turned to her. "Sorry it didn't work pout with Bubba. Later." He flew out of the Attic, flying away like a cloud in the wind.

"Marshall Lee." Realization hit Fionna like a train, making her eyes sparkle. "It's been Marshall Lee all along."

"Hey, Fifi."

Fionna looked down at the hole in the floorboard. Cake was frowning up at her, her tail molded to carry a plate of steaming chedder-and-chicken fettuccine. "I was wonderin' when you were gonna get back. Sorry for acting like a prissy. I got you some pasta." She held out the plate, and handed Fionna a fork.

Fionna took both. "Hey, Cupcake, I really need your help."

Cake glowed. "'Bout time."

Marshall Lee strummed the cords on his bass as he floated around his living room.

He felt guilty. He knew Bubba would be terrified of the things he told Fionna to do. He meant it as a playful joke, but seeing Fionna so sad and heavy-hearted made him feel like a brute. But why would Fionna like a guy like Bubba? He was so proper and giggly and...pink.

But Bubba was an easy forgiver. The whole ordeal would probably be history by tomorrow.

Marshall Lee connected his bass into his stereo system. He raised his hands, ready to play a song, when something else beat him to it.

A...harp?

Marshall Lee turned towards the window, where the song seemed to be coming from. Curious and confused, he floated over and looked through the grayed glass. "Ah jeez..."

Fionna was in her duchess gown once again. It had been cleaned, and her halo had been repaired, but most importantly, her harp had been fixed. She was played a nice, soft tune on it. Marshall Lee had to admit, she was pretty good at the harp. Cake stood a few feet behind Fionna, glowing. As Fionna played, she said in a sing-song voice,

"Marshall Lee,

Will you go to the movies with me?"

Marshall Lee groaned and opened the door. "Fionna, we need to talk."

Fionna and Cake walked inside. Fionna turned to Marshall Lee.

"Good evening, my dear

Your lady is here."

Marshall Lee choked down yet another groan. Crossing his arms, he gave the human girl a stern look. "Fionna, you really do NOT want to go down that road with me."

"With you, dear sir, I would travel down any road," Fionna smiled, "Especially if that road led to Couples' Only movie night."

Marshall Lee put on a sly smirk. Time for drastic measures. "Is that so?" He floated a few feet away. "Who would want to go to the movies with...THIS?!"

He exploded into inky blackness. Sticky, slimy tentacles shot out everywhere, pouring through the doorways and windows. His eyes were nothing bit red pits, and his teeth looked like needles. With one tentacle, he picked up a dazed Fionna and held her up to his horrendous face. "DO YOU WANT TO GO TO THE MOVIES WITH ME NOW?"

Fionna beamed. "How do you like your popcorn?"

Marshall Lee let out a thundering groan, shrinking his body back to normal form, never letting go of the human girl. "You are seriously starting to agitate me."

"Well, then let's do something cool. Like go to the movies!"

Marshall Lee tossed Fionna onto the rug. He sat down next to her, pinning her arms to the floor in case she tried anything else. "Listen, Fionna. I like you, I do, but I do NOT want to go to the movies with you, and you do NOT want to go to the movies with me."

Fionna understood. Sighing, she sat up, pulling her arms from the vampire's grip.

Marshall Lee felt a pang of guilt. "I'm sorry, Fionna. But you just do NOT want a relationship with a dude like me."

Fionna's eyes widened and her jaw parted. "Relation-?! Dude, I just wanna go to the movies!" She sighed. "But everyone hates me, apparently."

Marshall lee raised a raven eyebrow. "Wait. You DON'T want me to be your boyfriend?"

Fionna jumped to her feet. "Oh, GLOB no! MOVIES!"

"If you weren't looking for a boyfriend, why were you romancin' it up with Bubba all day?"

"Cupcake said that Couples' Only nights have special smooching requirements and emotional commitment and whatever else."

Cake went pink as she hit behind the couch. "I didn't really say all that...I n't ow ut ur lkin ut..."

"Of course I'll go to the movies with you!" Marshall Lee paused when he heard how excited he was. "As friends."

"OF COURSE AS FRIENDS!" Fionna cheered.

"Cool. But no Frenching."

"Yeah, alri-wait, WHAT?!"

Marshall Lee and Fionna laughed as they watched the movie, sitting on a line of plane seats. Ten other couples surrounded them, giggling and flirting. Fionna bubbled with joy. "I can't believe I'm finally here!"

The main title appeared on the screen. The screen changed to a scene of a man and woman standing in front of a train.

"Mon amour, I moust go."

"Mon cher, take me wiz you."

"But my père, he will be furiuz."

"Your père cannot deztroi our love."

"Je t'aime."

"Je t'aime aussi."

Fionna sighed in awe. "...Yeeeeeeah, this movie blows." She turned to Marshall Lee. "Wanna go hunt down some trolls?"

"You know it!" Laughing, Marshall Lee wrapped his arms around Fionna as she wrapped her arms around him. They took to the skies, their laughter washing all over the Land of Aaa...

TRIVIA

This episode reveals that Prince Gumball's first name is Bubba.

According to Fionna, when Cake is angry, she eats pasta to calm down. This is proven later in the episode.
