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.

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. It is shown that as a Lumpy Space girl, she is about 3 feet tall. The top of her has two long white lumps like her hat. The bottom of her is the same as her skirt. She has a small mass of yellow for her small piece of hair.

RAINY DAY DAYDREAM

Title Card

Fionna and Cake sit in the boat above the Treehouse under the sun, oblivious to the incoming storm.

"Awwww YEEEEEAAAAAAHHHH!" Fionna kicked right through the door onto the outdoor bridge. She landed on the wood on her back.

"Aww yeah!" Cake copied and landed on her. They both chuckled.

"Cupcake, get ready." Fionna smiled and picked herself up on her feet. "For a slap on the muzzle." She gave Cake a light slap on her white muzzle.

Cake snorted out a laugh.

"Seriously, though, get ready." Fionna walked to the middle of the bridge. "For...A DAY FILLED WITH ADVENTURE!"

"Whoa! Really?" Cake beamed.

"Yeah, girl!" She slapped Cake's muzzle again. Cake snorted again. "I wrote down on my arm this to-do list of cool junk to do."

Fionna looked down at the sloppy writing on her arm, twisting it this way and that. She was oblivious to the forming clouds behind her. "One: Somersault off this bridge and do the splits. Two: Hunt down and slay a troll horde. Three:" She turned around. "Storm clouds?"

Cake narrowed her eyes and blocked them from the sun with her paw. She looked closer at the rain drops...

...and saw they were metal...

Cake span around quickly. "FIFI! IT'S A MORNING STAR STORM!" Morning Star Storms were very rare, they occurred probably every ten years or so, but they were really dangerous. No one knows where they came from, but some think that the people of the Fungi War used them as weapons to slay the enemies.

Fionna slapped her muzzle again. Cake snorted.

"IT'S RAININ' MORNING STARS! C'MON!" Cake ran quickly back into the Treehouse.

"I've never seen a Morning Star Storm before." Fionna said in awe as morning stars began to rain around her, missing her body narrowly. "It's gorgeous."

Cake pulled her into the Treehouse right before a line of morning stars came at her.

"Looks like we're staying in today, kiddo." Cake said, setting Fionna down next to her on the couch.

Fionna sighed. "Alright. Well, what're we gonna do?"

As if in answer, a certain video-game-computer stepped in front of them. "Who wants to play video games?"

"Beema!" Fionna and Cake cheered.

"What's on the menu, Beema?" Cake asked excitedly.

"I have created a new game called Conversation Bizarre." Beema beamed, the title of the game flashing on its screen.

"START IT UP, BEEMA!" Fionna and Cake cheered. Beema stepped onto the wooden table and sat down.

What do you think about the clouds and the sun?

Fionna and Cake shrugged. "Okay." "They're cool."

That is an interesting response!

Beema fell to its knees. "Battery low!" It fell on its face. "Emergency shut down!"

Fionna booed.

Cake scoffed. "That was weak."

"What now?" Fionna asked.

"Let's just talk. Y'know, you and I hadn't just sat down and talked in a long time."

Fionna gave her a -_- face and pushed her away.

"I know something ELSE we can do!" Cake cheered excitedly.

"What?" Fionna said just as excitedly.

"We can use our imaginations! IT'S GONNA BE AWESOME, GIRL!"

"Puke that. Imagination's just for turbo geeks who can't handle how kick-butt reality is! I'M a kick-butt reality master!" She sat upside-down on the couch next to Cake. "Cupcake, I'd rather die than be imaginative like that. Seriously."

Cake shrugged. "Your loss."

"..."

"..."

"..."

"..."

"..."

"..."

Cake screamed suddenly and jumped up on the couch. "WATER! MONSTER-FILLED WATER ALL AROUND US!"

Cake screamed and jumped up onto the wooden roof, hanging on a branch. She panted and gasped, digging her nails into the wood.

Fionna rolled her eyes. "Shut up, Cupcake."

"FIONNA, DON'T! DON'T TOUCH THE FLOOR!"

Fionna rolled her eyes and sat up. She raised her foot over the floor.

"SERIOUSLY, FIFI! THERE MUST BE A CURSE ON THE HOUSE OR SOMETHING! THE FLOOR HAS TURNED INTO MONSTER-FILLED WATER!" Cake screamed desperately.

"I'm not playing you're childish games, girl." Fionna said seriously. "Watch and learn as I master...Reality..."

Fionna brought her foot slowly down to the floor.

Cake screamed. "NOOOOOOOO!"

Fionna felt a pair of jaws clamp down on her flesh. Fionna screamed and punched the invisible force in the 'eye.'

She sat, gasping and panting, looking at her bleeding leg. "CUPCAKE! WHAT THE HAY-HAY?"

"I don't know, girl. I was just playing around with my imagination." Cake said. She looked down at the murky water, scaly monsters, and huge crabs. "And then everything got serious."

"It's like...whatever you imagine becomes real." Fionna said, grabbing some nearby gauze and wrapping up her leg. "That's papayas!"

Cake paused, then shut her eyes tight. "Don't imagine your brain blowing apart. Don't imagine my eyeballs melting out of my skull."

Fionna jumped across the room to the opposite couch, picking Cake off of the roof. "Cupcake! Imagine Beemo has a better game! AND NEW BATTERIES!"

Fionna gasped as she felt the couch starting to move. She looked down and saw that the couch was sinking into the floor/water. "DANGIT, CUPCAKE! STOP IMAGINING WATER!"

"I can't my imagination's too amazing!"

Fionna grabbed Cake and threw her over to the window, quickly following. "Then imagine turning your imagination off!"

"I think I can imagine...a switch that turns off my imagination off." Cake said instead. "Upstairs, surrounded by goblins, trolls, monsters...and...and..." She giggled. "And boys...Really cute boys and kittens."

"Can't you make it easier? Put it downstairs?"

"Hey, I'm visionary! You can't hold this baby back! That's bad parenting, mama!"

"THEN IT'S TIME TO TAKE YOUR IMAGINATION DOWN TOWN! LET'S GO TO THE DEN AND SUIT UP!"

"AWESOME!"

Fionna crawled on the ceiling through the doorway to The Weapon Room. They both looked around. The shelves were still stacked with books, the same red divan was to the right. It still had its mahogany desk and chair against the far wall, its ink bottle and open book set. There was a book shelf above it, stocked with helmets and books and daggers. It had the same plaque of a 'Deadly Goliath Beetle', its dog-sized shell still covered in a skull. People said people in the Fungi War used these to poison enemies.

"Grab that torpedo." Cake said, pointing to the large torpedo they had dug out from some Fungi War ruins.

"OK." Fionna hopped onto the shelf and grabbed the torpedo.

"And grab that Infinity Armor." Cake pointed over to a nearby armor suit made of gold and silver.

"Nah. There's a better suit over there." Fionna pointed across the room at a bejeweled, shining suit.

Fionna jumped across the room...

...only to smack right into something in midair.

"Cupcake?" Fionna pressed her hand against the force. It felt like concrete. "What is it?"

"I'm imagining a wall." Cake patted Fionna on the head. "You can just go around it."

"Really? That's it?" Fionna felt around the invisible glass until she felt the end. She scooted to the other side. "There isn't an invisible mad goblin or anything?"

In answer, there was a loud growl.

Cake sighed. "Well, there is one now. Look out, it's trying to bite you!"

There was the sound of chomping jaws. Fionna felt the goblin lung for her. Fionna jumped over the goblin. "I'll kill you, goblin!" The goblin snarled and chomped again. Fionna turned around and punched and kicked at the air in front of her, she knew all goblins were short, but her hands and feet never collided with anything.

"You're fighting too high!" Cake informed her. "She's taller than you!"

Fionna nodded and kicked and punched higher. She felt her hands and feet collid roughly with scaly skin and continued to fight. The goblin began to whimper in pain.

"You're gettin' her now!" cheered Cake.

Fionna attempted an over-cut at the goblin, put she felt more smoother skin than before in confusion.

"Now you're over-cutting her family." giggled Cake as Fionna did another over-cut.

Fionna span in a circle, swinging her foot around, socking something in the face. It wailed.

Cake giggled again. "You just socked her husband in the face." Cake's face went serious. "Uh-oh. Their children's coming back for vengeance."

"Cram this! We gotta book it to your imagination machine!" Fionna rolled her eyes. She looked around for an escape route, but only found the window. She set herself for a pounce.

"Fifi," Cake warned her, "Don't! The Morning Star Stor-!"

Fionna shot through the window's glass. She landed in something. She opened her eyes to see that she and Cake had fallen into the basket she had set up to the Attic. The Morning Stars continued to pour down harshly, but they whizzed past them.

"We'll take the shortcut to the Attic!" Fionna cried, and began to pull on the rope on the basket. The basket began to pull up through the air. Finally, they were in the safety of the Attic. It was dusty yet damp in there, Fionna couldn't remember the last time she had been in it. The same folk guitar was hung on the wall, the small door to the left side. There was the same cardboard box and picture of Lord Monochomicorn on the floor, on top of the knitted rug.

Fionna and Cake panted heavily. Fionna set the torpedo down beside her. Cake fell over on her side. She looked up and noticed a Candy Kingdom Assorted Chocolates box, the blue ribbon still attached, and two unopened Wildberry Prince's Juice boxes.

"Hey, Fifi, I found some candy." Cake opened the box. Most of the chocolates were gone, eaten, but there were still about four left. She picked out two chocolates, a caramel-swirled one and a cherry-topped one and popped them into her mouth. "Tastes like raspberry candy." She took the plastic off of the juice box, popped the straw in, and took a big swig of it. She grabbed the chocolates and stretched it over to Fionna. "Try some."

Fionna took the last two chocolates, the chocolate-coated strawberry one and the cream-coated one, and ate them quickly. She took the other juice box, drank it dry, and swallowed. "OK." She dropped the empty boxes and looked out of the little door, out to the bridge. "Try to imagine some kind of metal canopy over the bridge so we don't get morning starred."

"OK." Cake squeezed her eyes shut and paused. "It is done."

Fionna looked outside and saw that the morning stars had all stopped right above the bridge, blocked by the canopy. She took a cautious step onto the bridge to deem it safe. It was. "Awesome!"

"Halt, travelers!"

Fionna span around, torpedo still in hand, expecting to see some kind of witch-y woman. But there was no one in sight. But there was defiantly a female at the end of the bridge.

"To cross this bridge you must first pass my enigma!"

Fionna made a -_- face and turned to Cake. "Really? An Enigma Witch?"

Cake gave an embarrassed guffaw and blushed.

"Ask me your enigma, Enigma Witch!"

"Brace yourself. For this riddle comes from a paranormal, disbelieving land."

"Lay it on me!" challenged Fionna.

"Yes, er...uhhh...ummm..."

Cake looked up at Fionna. "I can't think of a enigma."

"Just make it super easy."

"Tell me, traveler. What is simple, yet also difficult?"

Fionna gawked. "What kinda enigma is THAT?"

"THAT IS THE WRONG ANSWER! THE PENALTY IS DEATH BY SCORPIONS!"

There was the sound of hissing scorpions.

"YEAH RIGHT!" Fionna cried. "I'VE GOT A TORPEDO!"

Fionna threw the torpedo across the bridge at the opposite side. There was a small explosion and the hissing grew very loud and the Enigma Witch screamed. Fionna felt the weird feeling of something(s) falling on her.

Cake must have felt it too, and shrieked. "YOU EXPLODED THE SCORPIONS RIGHT AT US!"

Fionna shrieked as she felt the scorpions begin to sting her. It stung like white-hot coals being thrown at her. Soon, large, red, swollen bumps dotted her skin. "I can feel them all over me! IMAGINARY POISON! COURSING THROUGH MY VEINS!"

Cake sobbed, red lumps peppering her fur. "I'M SORRY, SISTER! I'M SO SORRY!"

Fionna grabbed Cake's paw and ran to the gaping hole in the Treehouse's bark. "CUPCAKE! BE MY EYES! TELL ME WHAT I'M UP AGAINST!" She picked up Cake and set her on her shoulders as they entered the Treehouse.

Cake nodded and began. "There's a little rabbit family by the furnace. They're fine. There's a troll with grenade launchers for hands on the ceiling. An Anima Eater just got out of the mini fridge and...a bunch of tarantulas, super-spikes, and doo-doo is firing at us RIGHT NOW." Cake squeezed Fionna's face. "JUMP, FIFI!"

Fionna jumped over the doo-doo, super-spikes, and tarantulas, and they all crashed into the wall behind her, denting the bark.

"HERE COMES THE ANIMA EATER! BREAK IT'S SPINE!" Cake called.

There was a ghostly howl. Fionna felt the Anima Eater pounce for her and jumped up, sending the Anima Eater under her. She brought her feet down on her spine, causing it to crack loudly. Fionna heard a strange revving sound.

Cake deadpanned. "Fifi. The Grenade Launcher Troll has you in her sights."

"HEY!" Fionna yelled. "DON'T FIRE AT US WITH THAT GRENADE LAUNCHER!"

The troll giggled evilly. "Teeheeheehee..."

"DON'T YOU DO IT!"

"Teeheeteeheehee..."

"DON'T DO IT, GIRL!"

"Eh...Ok."

"Awesome." Cake and Fionna high-fived.

"Hey, try to imagine something." Fionna set Cake down on the floor. "This poison is about to kill me."

"Alright." Cake crawled under Fionna's legs, lifting her off of the ground. "Goin' up."

They reached their Bedroom immediately. "The imagination switch is right of the bed." Cake said.

"Is it clear?" Fionna asked.

"Yeah, I mean there's a bunch of cute boys, but they shouldn't bother you."

"Roger that!" Fionna hopped off of Cake's back. She immediately heard the voices of the boys, talking and laughing. They must have been boy CATS, because she occasionally brushed against something furry. She went to the right of the bed, feeling around for the switch. Finally, her hands rested on cool metal. "I found the switch!"

"Way to go!" cheered Cake, who was currently sitting between a black Bengal and a gray Burmese cat.

The Burmese chuckled.

Cake turned to him. "Dang, boy. If you weren't my imagination, I'd have yo baby."

The Bengal laughed gave a humored scoff.

"What chu laughin at?"

"I'm gonna turn it off!" Fionna called.

Suddenly, something punched her away roughly. "OW! YOU SAID IT WAS CLEAR!"

"I can't see anything!" Cake gasped. "I must have imagines an invisible monster!"

"How do I kill it?"

The invisible monster brought its scaly fist down on her back. Then it smacked her three feet away.

"I'ma coming, Fifi!" Cake called as the male cats began to run away.

Just as the monster socked Fionna in the gun, Cake popped up between them. "OK, INVISIBO! EAT A PIECE O' THIS!" She brought her furry fist to its fuzzy face. "HURRY, FIFI! GET TO THE LEVER!"

"OK!" Fionna ran over to the right side of the bed as Cake wrapped her body tightly around the monster. Cake felt the monster hit her pressure point roughly.

Fionna gasped. "Cupcake!"

"Do it, Fifi!" Cake called, wrapping herself more around the monster.

"I'M DOIN IIIIIIIIIIIIT!" Fionna grabbed hold of the lever.

And pulled it down.

Cake let out a war-cry. "I'VE GOT YOU NOW-" She froze dead and fell to the floor, limp.

Fionna looked down. Her injured leg, lump-covered skin, and scratched arm were completely healed. "Aw yeah! The imaginary poison is gone!" She turned around. "Cupcake?"

Cake was now back to her normal size, limp on the floor. She was unmoving.

"Cupcake." Fionna ran to her side. "Are you OK?"

Cake groaned.

Fionna patted her ear. "Hey, come on, wake up."

Cake sat up, her face blank. "Yes. Hello, Fionna. I am awake and healthy." Her voice was robotic and blank.

"Cupcake. What's happened to your explosive personality?"

"I have no idea what you mean." Cake said, standing. "I am perfectly explosive."

"No, girl. Something's wrong." Fionna said skeptically. "Tell me something amazing."

"But Fionna. I cannot tell you something amazing. For there is nothing amazing happening around us for me to describe for you."

"See! You stink now! Oh, clam, it's your imagination. You need that thing!" Fionna groaned.

Cake reached over and grabbed her dulcimer. She played the G string. Again. And again.

"Cupcake, stop. You're just playing one continuous note."

"One note is all that is needed."

Fionna sighed. "I don't care if the house explodes. I'm turning your imagination back on."

She walked back to the right side of the bed. She felt around for the switch, but it was gone. "Cupcake, your imagination switch is gone."

"Yes. Doth thou not remember shutting down mine imagination?"

"I remembereth." Fionna sighed.

"I am pleased my imagination is gone." Cake said blandly. "It was for fools. It was purposeless."

"No! No, it was the opposite of that stuff!" Fionna sighed sadly and looked down at her Mary Janes. "I realized it too late, though."

Cake paused, then nodded. "Indeed. Well, if my imagination is so explosive, why don't you imagine an imagination-on switch for me?"

Fionna rose an eyebrow. "What? No! Imagination is what you need! I don't do any of that junk-a-grub!"

"Fionna, you sound irrational. Perhaps you should reconsider your statement."

Nuts. Fionna thought. Cupcake's right. She's always so right. Makes me feel...embarrassed.

Fionna turned angrily on Cake. "CUPCAKE! YOU MAKE ME FEEL EMBARRASSED A LOT!"

Cake narrowed her eyes. "I do not deserve being talked to like this."

Fionna sighed. "You're right. Again. OK, I'm going to try to imagine another imagination switch for you again. But do you know if there's anything fruity in my imagination? Because if there is, I'm gonna be cheesed."

Cake suddenly growled and pounced on Fionna's back. "But I do not want my imagination back on!"

"Get off, Cupcake!" Fionna yelled as she fell to the floor.

"Swear to me you will not accept this mission!"

"No!" Fionna chucked her off of her back. Cake fell on the floor, glaring. "You're boring and weird now! I'm turning your imagination back on!"

Cake stared at her blankly and stood. "Very well, Fionna. You leave me no choice. I will cut out your brain and destroy it by stomping it apart and eating it."

Fionna quickly shut her eyes and concentrated. "Imagination...GOOOOOOOOOOO!"

She felt herself fade from the room.

Fionna looked around. Nothing was in sight. It was all just so...WHITE AND BLANK. "What the flub?"

She put her hands on her hips and looked around. "Well, this isn't so bad. Nothing lame at least." She turned around. "Hey! Cupcake's imagination switch! Awesome!"

Out of NOWHERE, a brunette girl with green skin, brown hair, and a longish blue dress stepped out, playing a tune on a harp.

"I am your imagination girl.

Welcome to your imagination world!"

Fionna rolled her eyes as the girl went on singing about imagination. "Maybe I can try imagining something." She concentrated.

The harp-girl went dancing around, strumming the harp, singing "Imagination world, world, world." She did a spin. Fionna imagined a baby seal behind her feet and a plate of pasta further away. The harp girl tripped over the baby seal and fell, her face splattering into the pasta.

"Awesome." smirked Fionna. "Now for that switch."

"Greetings!"

Again, out of nowhere, something landed on her shoulder. Fionna looked down to see a sort of pink-blue-purple butterfly wearing a sunhat. "My name is Bella Butterflee. Would you care for a napkin my son made? He engraved it with his tears. You see, he just broke up with a lovely miss-"

"NO!" Fionna yelled. "How'd you get in my imagination?"

"I'm not sure. You tell me. Maybe I represent your secret desire to be civilized."

Fionna rose a fist. "REPRESENT THIS!" She flicked Butterflee off. "And this!" She concentrated.

Butterflee groaned. "What's this I feel?" Suddenly, her wings turned to metal, slapping her over and over. "Oh! Ow!"

Fionna concentrated again. A small horde of tiny seals wadded up to Butterflee and dragged her off. "Seals. Teehee."

Fionna ran over the imagination switch. She pulled down the lever.

Cake felt her brain fill with some kind of power. "Ooh!"

Suddenly, a small wood sprite hopped onto the imagination switch.

"Hey!" called Fionna. "Get away from that!"

The wood sprite hopped over to the buttons on the machine and with his elbow, hit HYPERDRIVE.

Cake's brain swelled rapidly. She screamed. "I CAN IMAGINE EVERYTHING!"

Fionna grabbed the sprite and tossed him away. "Take a hike!"

She hit the NORMAL STYLE button on the imagination switch.

Cake groaned and fell limp on the floor. "Oh Glob. I imagined my Dad. Naked. EW..."

Fionna faded back into the room. She looked down at Cake. "Cupcake! Are you OK?"

"I think so. Let me check." Cake squeezed her eyes shut. "Hmmm...Yep. He's clothed now. And hey!" She ran over to the window. Morning Stars covered the ground, already melting into the ground. "The Morning Star Storm's gone! Let's go on an adventure!"

"I dunno, Cupcake. I think we've got an adventure right here. With..." She closed her eyes. "MONSTER-FILLED WATER ON THE FLOOR!"

Cake screamed as she sunk into the floor. She quickly laughed and picked herself up. "I'm fine."

Fionna rubbed behind her ear. "Good cat."

TRIVIA

While Fionna and Cake are in one part of their Treehouse (after sitting in a bucket using a pulley system), the initials AT are carved into a heart on a wooden beam, possibly referring to the show which they are on.

The knitted rug that is in the Attic says Mom is the Bomb!, which most likely means that Fionna and Cake's mother knitted it for them but they forgot it.

Cake stated that in the bedroom, there would only be "cute boys and puppies", but when they got to the bedroom, she said "It's just a bunch of cute boys but they shouldn't bother you", completely forgetting about the puppies.

CONTINUITY ERRORS

At the beginning of the episode, Fionna has the to-do list on her arm, but after they enter the Treehouse, the list is gone.

I'll start saying a lot more about the Fungi War from now on. R&R!
