CHARACTERS IN THIS EPISODE:

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.

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.

Lord Monochromicorn—Prince Gumball's loyal companion and Cake's boyfriend. He is completely black with a long, gray mane, entirely different from Lady Rainicorn's multicolor scheme. He is more horse-like compared to Lady Rainicorn, although he still has a horn. He can also open black holes and fly. He speaks in Morse code, much like how Rainicorn speaks Korean. He can also neigh, despite him speaking in Morse. Lady Ranicorn has said that she flies by using light and "dancing" on it. However, Monochromicorn is black, which would mean he would absorb light. Lord Monochromicorn resembles a horse and a moonbow, a rainbow seen at night.

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.

Tree-Trunks—the male version of Tree Trunks is seen with a gray mustache and a green, see-through visor. He also has a few wrinkles on his trunk. This may imply that he is also old, like his female counterpart. He also wears a bright blue ribbon on his tail. He has thicker eyebrows than Tree Trunks.

Mrs. Creampuff—She is a female creampuff who used to date Prince Gumball. She looks like a cream puff, hence her name. She has chocolate on the top of her head. He also wears a flowery hat, and, like a cream puff, he may also be filled with cream or ice cream.

Starchie—A female malt ball who is a resident of the Candy Kingdom. She's a chocolate malt-ball with a pink hat, boots, and brown hair. She also has the same mustache as Starchy.

Mrs. Cupcake—she is a burly female cupcake and a resident in the Candy Kingdom. She appears to look exactly like Mr. Cupcake, but without his mustache and does not have a pink nose. It is revealed that in Slumber Party Panic, she is strawberry-flavored.

Mandy—she is a piñata who appears to live on the ceiling of the Grand Hall. She looked like Manifred, although she is neon green and hot pink and has eyelashes.

SLUMBER PARTY PANIC

"Yeah, you think you're way up there, but I can get you!" Cake called, growing 10 times larger to catch up to Lord Monochromicorn in the purplish sky. He neighed in reply.

Down below, in an old cemetery, Fionna and Prince Gumball were standing in front of a stone table. They both wore goggles, although Prince Gumball was wearing a lab coat as well.

"Just three more drops of explosive ears…" Prince Gumball said slowly, carefully dripping the liquid into the glass container.

A puff of smoke erupted in the shape of a skull. The liquid sparked a dark turquoise color. "Ooh!" Prince Gumball and Fionna said in unison.

"Hey Prince Gumball," Fionna said as Prince Gumball scribbled down something in his notepad, "When we bring the dead back to life, will they be filled with worms?"

"No," Prince Gumball said. "If my Decorpserum works, they should be as young and healthy as you are."

Fionna pounded her chest like an ape.

"Hand me that platter, tough girl," Prince Gumball laughed.

Fionna lifted the platter, revealing a pile of dirty garbage. "Old Mrs. Creampuff?"

Prince Gumball chuckled. "We used to date."

He injected the garbage with the serum. It oozed with the liquid.

The garbage glowed a puke green color. "Something's happening!"

Prince Gumball and Fionna crossed their fingers. "Come on…" "Come on…"

The garbage sprouted stubby arms and legs a hole appeared in its face as a mouth. It groaned.

"ALGEBRAIC!" Fionna cheered.

"Wait…something's wrong…"

"SUGAR!" The garbage moaned.

The liquid oozed out of every hole in its body. Prince Gumball and Fionna flinched.

The garbage jumped into the largest container, turning the blue liquid green. The container shattered into a million pieces, and all the liquid landed on the graves.

One by one, grubby, dirty hand erupted from the ground. Deceased candy people came out, moaning.

"Hey, look! The Decorpserum is working!" Fionna said.

"No! This is wrong!" Prince Gumball exclaimed. He looked at a female-looking heart that read, BE MINE. "They're still dead! The Decorpserum serum! It's incomplete!"

The heart growled at him and rasped, "Must. Eat. Sugar."

Fionna stuffed it down into the hole it crawled out of. "You're grounded!"

"This is really bad," Prince Gumball said worriedly. "They'll be attracted to the Candy Kingdom!"

"Why?"

"Because, the Candy People are made of sugar, ya ding-dong!"

Mrs. Creampuff crawled on him, making him yelp. "Give me some sugar, baby."

"Chew on this!" Fionna cried, kicking Mrs. Creampuff in the face.

Prince Gumball chuckled. "Good one, Fionna." He ushered for Fionna to go to the gate of the cemetery. "Quickly! To the kingdom!"

As they ran out, Fionna kicked a caramel-person in the face, yelling, "Get a life!"

Later, as the sky grew dark, everything was silent. The two 50-foot gumball-like statues sat on either side of the castle, blowing bubbles out of a ring. The 50-foot-tall cotton-candy tree that grew on the top of the castle rustled. The ice cream cones, frosting, and sprinkles adorning the castle stayed still. The chocolate rivers flowing down the castle's sides rushed calmly. Everything was silent—

DONG! DONG! DONG!

Out of the blue, a giant bell chimed.

Prince Gumball stood in one of the towers of the castle, ringing the bell. "ALL CITIZENS OF THE CANDY KINGDOM! REPORT TO THE PALACE! IMMEDIATELY!"

Murmuring curiously, all the Candy People walked to the castle.

"Whoa!" Cake yelped, and she and Lord Monochromicorn dashed to the castle.

Prince Gumball looked at the citizens, then at the approaching zombies. "Hurry, citizens…"

Later, at the entrance, Fionna was guiding everyone in. "Alright! You heard the prince! Everyone in! All right, no pushing! Come on!"

"What's up?" Cake asked Fionna as he and Lord Monochromicorn came in.

"The prince will explain everything. Tree-Trunks! Get those hot biscuits in her, dude!"

"Oh, I hope everything's okay…" Tree-Trunks came in, carrying a basket of hot biscuits.

Prince Gumball and Fionna shut the doors. "Did we get everyone?" Fionna asked.

"All present and accounted for," A talking female piñata said.

"Thanks, Mandy," Fionna said.

"You're welcome."

"Citizens," Prince Gumball said, "We assemble here in the castle for a momentous announcement! Tonight, we are all going to have…a slumber party!"

"WHAT?!" Fionna exclaimed.

All the Candy People cheered. Lord Monochromicorn neighed, and Cake gave a thumbs-up.

"Wait," Fionna said, "What about the zom—"

Prince Gumball slapped a hand over her mouth. "Go ahead and start partying!"

"Buth Gumballb," Fionna muffled under Prince Gumball's hand, "Tha undread!"

Prince Gumball slapped his over hand over her mouth. Grabbing her, he called, "We'll be right back, everyone!" and ran into an empty room.

"Fionna," Prince Gumball said in the empty room, "The Candy People can't know about the zombies!"

"WHA?" Fionna cried.

"If they knew, they would flip out!" Prince Gumball explained.

"What do you mean, 'flip out'?" Fionna asked.

"I mean, they would flip. OUT."

Starchie walked into the cemetery, calling, "Prince? It's me, Starchie the gravedigger. I brought you a larger corpse shovel."

No response.

"Oh Prince? Well, I'll just wait for you here, then. At the mausoleum. With my back turned. And my defenses lowered."

A zombie crawled out of the mausoleum. Starchie turned curiously around, her eyes wide.

"Sugar…" The zombie groaned.

Starchie screamed. And screamed. And screamed.

She exploded.

"CANDY PEOPLE EXPLODE WHEN THEY GET SCARED?!" Fionna exclaimed.

"Not letting the Candy People know about the zombies is so important that you need to promise." Prince Gumball waved his arms dramatically. "Royal Promise. Not to let anyone know about the zombies. Ever."

"Okay, sure."

"No, Fionna. You have to Royal Promise."

"Yes," Fionna knelt down, a hand on her heart, "I Royal Promise."

"I'm going to go to my lab and finish the Decorpserum," Prince Gumball said, "You keep the Candy People distracted and ignorant. Can you do that?"

"Yes, your highness."

"Good. Don't tell anyone about the zombies." Prince Gumball turned to the door. "Never ever."

"Oh, wait," Fionna called as the door closed, "Can I at least tell Cake?"

"Tell me about what, girl?" Cake asked as she opened the door.

"You know, about the outbreak of zom—" She slapped a hand to her mouth.

Cake chuckled. "Alright, what's going on?"

Fionna nervously laughed. "Nothing. Nothing at all, gal-pal!"

"Hey, I think you and Gumball are up to something," Cake said skeptically.

"What? No! No way!" Fionna lied.

"Ya'll are up to something!" Cake beamed. "Is it some sort of prank? Can I get in on it?"

"Who wants to play Truth or Dare?" Fionna said nervously, running away.

Cake tapped her chin with her eyes narrowed.

"Okay," Fionna said to the ring of Candy People as Cake sat down, "Cocobarry, you dare someone to tell a deep truth or a saucy dare."

"Mrs. Cupcake," Cocobarry said, "Suce or Dare?"

"Dare," Mrs. Cupcake said.

"I dare you to take off zour icing."

The crowd all replied, "Ooooooooooooooooooh!"

"Hey seriously, girl," Cake nudged Fionna, "I'm your sister. Sisters are supposed to tell their sisters everything all the time. What are you and Gumball up to? Is everything all right?"

"Yep! Fine! Everything's great! Except for that. Whoa."

She looked at Mrs. Cupcake, who had taken off her icing, revealing a brown top.

There were murmurs from the crowd, "Wow." "She did it." "I didn't know she was strawberry."

"Cake," Mrs. Cupcake said in a Peruvian accent, "Truth or Dare?"

"Truth."

"Would you prefer chocolate or fudge?"

"I can't eat chocolate or fudge because I'm a cat and they'd probably kill me, but…probably…neither! Fionna! Truth or Dare?"

"Dare! Ha-ha!" Fionna answered.

"I dare you…to tell me the truth about what's going on in your mind! What were you and Gumball talking about when you were alone together?" Cake dared her, her hands on her hips.

The crowd gave an exaggerated "Oooooooooooooooooooooooh!"

"Um…uh…" Fionna thought nervously. "The truth is…"

He imagined Prince Gumball scolding her, You promised you wouldn't flippin' tell anyone! You're so cute, Fionna…

"Uh…the truth is…I'd rather play Dodge-Shoe!"

She took off one of her black shoes and threw it at Cake.

"I'm not playing Dodge-Shoe until you stop dodging my questions!" Cake told her. She sniffed the shoe skeptically. "Hey…Old Mrs. Creampuff? Isn't she dead?"

"Give me my shoe back!" Fionna groped for it, but Cake moved it out of her reach, "Dodge-Shoe was a bad idea!"

"Look, girl, tell me what's going on! You are acting crazier than a cannibal! You're making my tail frizz out every time you…"

Fionna didn't hear the rest. She looked past Cake through the window, at the approaching zombies.

Oh goodness! Fionna thought desperately The Prince hasn't finished the equation! And the zombies are here!

She put her back to the window so that Cake couldn't see the zombies. "The truth is, he wanted the party to be super-fun, and if I did have something to tell you, then I would, in a second, and it would make my life easier, unless there was something was stopping me, like a promise, but there isn't, so I won't, so it's cool!"

She saw a zombie come to the window. She closed it hurriedly, as Cake replied, "What? You lost me."

"Uh…Hey, you know what time it is?"

"Adventure time?" Cake shrugged.

"No! it's time for Bloody Jerry! You're first!"

"Really?" Cake asked as Fionna pushed her away from the window.

"Lord Monochromicorn! Get into the bathroom with Cake!"

Lord Monochromicorn tapped the floor twice and stomped once and circled his foot to say, Coming! (I can't really speak Morse Code. I'm just making it up.)

"Okay, okay," Cake said as Fionna closed the door, "But when Jerry comes, I'm coming out to make you spill your beans, Fionna!"

"I can't hear you! Jerry's making too much noise!" Fionna called, opening the window to look at the approaching undead.

All the zombies grew nearer to the castle, moaning, "SUGAR!"

A couple of zombies started banging on the door to the castle. A female malt-ball who was sitting on the front stairs heard it. "Um…Does anyone else hear that?"

"What? Hear what? I don't hear anything!" Fionna lied nervously.

But all the Candy People murmured curiously as the banging continued.

"I'm hearing a noise I don't understand…" The female malt-ball whimpered. She began to shiver, "And it makes me scared!"

"What? No, Chelsea!" Fionna told the malt-ball, "What noise?" She turned on the boom box sitting next to Chelsea. "You mean this noise?"

And once the music started, Chelsea was immediately running to the dance floor to dance. Soon, the Candy People completely forgot about the banging noise and started dancing to the music as colorful lights began to flash.

"Yeah! Dance!" Fionna encouraged them. "Go! Don't stop—Gasp!"

Coming through the far wall's door was a popsicle zombie, moaning, "Sugar…"

Fionna, taking immediate action, ran through the crowd, grabbed a long wooden bench, and ran for the door.

"What iz thiz game hou are playing now, Fionna?" Cocobarry asked her.

Fionna pressed the bench against the door and, looking at Cocobarry as she hammered it to the door, replied, "Uh…It's…Block-O-Do! The game of barricading! Come on, block all the entrances and windows!"

The Candy People cheered at the thought of the "game." Everyone ran around the Grand Hall, grabbing furniture and hammering it to the windows and doors, blocking out the zombies.

"Alright," Fionna thought aloud, "This is not a permanent solution. Think, Fionna, how can you keep from everyone from finding out…?"

"Find out about what, Fionna?" Mandy asked her from the ceiling.

"Mandy, the talking piñata, you're convenient appearance gives me a great idea!" Fionna realized. She ripped a leg off the bench, "Everyone, new game! Everyone grab a stick! Let's mash some piñatas!"

"What?!"

"Not you, Mandy."

"Oh, thank goodness."

"Now," Fionna took some strips off of a paper-Mache-looking animal. "Everyone put on some blindfolds!"

The Candy People, blindfolded and sticks in hand, cheered. Fionna got into the center of the crowd. "OK, everyone, get together!"

The Candy People huddled into a large group.

"I'm hanging the piñatas!" Fionna said as the zombies began to break through the blockings. "They're all around you!"

And just as all the zombies broke through, Fionna cried, "Smash the piñatas!"

The Candy People ran around, cheering, hitting the zombies with their sticks successfully. Fionna, being the only one who new what was going on, kicked, punched, and stabbed multiple zombies. The Candy People were hitting the zombies madly by now.

"Yeah! You guys are on fire!" Fionna told them.

Cocobarry stabbed a zombie, and a fountain of sugar and candy spilled out. He began eating it (almost cannibalistically.)

Soon, all the zombies were out cold and all the Candy People were eating the sugary treats that had come from them.

"WE DID IT!" Fionna cheered in triumph. "My stupid plan worked!"

"Bye, Jerry," Cake said to a bloody, deformed man seconds before he disappeared as she stepped out of the closet with Lord Monochromicorn.

When she saw everyone eating sugary candy and the brittle zombies everywhere, she gasped and ran up to Fionna. "WHAT THE NUTS HAPPENED HERE?!"

"Oh, we killed all the zombies Prince Gumball and I raised from the dead," Fionna said casually.

"Really?" Cake asked.

Everything froze. The Candy People stood still, unblinking with their hands still full of treats. Cake stood unblinking, still having a shocked expression on her face. Fionna was the only one in the room moving.

"Cake?" Fionna asked, waving her hand in front of her friend's face. "Cake? What's going on?"

At that moment, Prince Gumball walked into the room with a vial in his hand.

"Wha—?" He looked around at the frozen setting, "Fionna, did you break your royal promise?!"

"Yeah," Fionna said, flustered, "But—I mean—all the zombies are dead! The Candy People won't freak out! What's the big deal?"

"This is really, really bad, Fionna!" Prince Gumball told her. "You can't break Royal Promises! Never ever, no matter what, forever!"

At that moment, everything shook madly. The walls cracked and the floors shook, but everyone stood frozen.

"The guardians of the Royal Promises are coming for us…" Prince Gumball whispered hoarsely.

A enormous hand broke through the ceiling and scooped the two of them up. "AAAAAAAAAHHHHHHHHHHH!"

The hand's owner turned out to be one of the gumball-machine-like statues that sat on either side of the castle.

"Fionna the human," It said in a robotic female voice, "You have broken a Royal Promise. For which the penalty is…trial by fire."

The other statue erupted flames from its mouth.

"That's stupid." Fionna said.

"WAIT!" Prince Gumball told them. "She's my friend! Isn't there another option?!"

"Yes," The first stature said, "Because you care for the promise-breaker, we will give her a less hot trial. You must now answer…"

"Math questions!" The second statue said.

"Mathematical!" Fionna said.

"Fionna, you're terrible at Math!" Prince Gumball told her.

She sighed.

"Now," The first statue said, "Solve this!"

The second statue made a hologram with its eyes, reading:

8V=G7DJUFN+R73(T)NFD64JG9+GHF98HTW948TH9GS8%FIUNTG94584Y{F85}UTRH485YU49RTGH I9485U9486U346E8TU98UT596U0596U5=?

"Uh…" Fionna gawked.

"Oh, wait," The statue shut down the hologram. "I thought of a better one."

It put up another one, reading, 4+4

"Yes, four plus four!" The first statue agreed. "Solve it or die."

"Uh…" Fionna thought. "Eight?"

The statues laughed, then froze. "Oh. Correct."

Time sped up the second statue leapt back into its place, picked up its bubble wand, and froze. The color came back to everything. The chocolate fountains began running again.

"What's happening, Prince Gumball?" Fionna asked him as things started to shake roughly again.

"You defeated the Royal Promise! The guardians are resetting!"

The first statue dropped them and went back into its place. Just as they were falling, Prince Gumball and Fionna vanished.

Prince Gumball and Fionna appeared in the lab.

"Slam-a-cow!" Fionna cheered, "That was tops! I was all, eight!"

"Eight…eight…" Prince Gumball beamed with realization, "That's it! The answer was so simple, I was too smart to see it!"

"You're welcome."

"Eight is the last number I need for the Decorpserum!" Prince Gumball told her, drawing an 8 at the end of an equation on a blackboard.

Later, Prince Gumball put a little drop of an orange liquid on a zombie. It glowed, then it became a live, healthy, apple Candy Person.

Prince Gumball and Fionna went around the room, bringing the zombies back to (healthier) life.

"This is messed up," Cake said, "But sweet!"

Lord Monochromicorn neighed in agreement.

All over the Grand Hall, Candy People went to go see their previously-dead relatives.

"Uncle Chewy!"

"Grandma!"

"All my dead relatives!"

"Starchie!" Cake said, greeting the malt ball.

"Morning!" She said.

"Girl," Cake told Fionna, "You broke a Royal Promise? You crazy! All you had to say is that it was a royal secret! I would understand!"

Prince Gumball walked up to Fionna as Cake walked away and said, "I hope you grasp the full consequences of breaking promises."

"Flip yeah! If I break a Royal Promise, I get to fight zombies, solve Math problems, and—and—"

"Okay, okay, calm down," Prince Gumball told her.

"And reverse death itself."

"You really are adorable," Prince Gumball told her, "But keep your promises, okay?"

"I will, Prince," Fionna told him.

She looked down to see Starchie chewing on her leg.

"Starchie, you're not a zombie," Fionna told her, plucking her off of her leg.

"I can't help it. Flesh is delicious."

"You're delicious?"

"Don't squeeze me, I'll burp! *BURP*"
