Chapter One: Cleaning Day

"Gah! I hate cleaning day!" The words echoed throughout the treehouse in the land of Aaa. Fionna plopped herself down on the couch while Cake started picking up random piles of clothes and treasures in the living room.

"Girl, you're just gonna have to get over it. Do you see this house right now? I don't like cleaning either, but even I can't stand living in this glob forsaken mess!" Cake continued to layer the piles of junk in her ever-growing paw. She lifted up the pile next to the window and discovered BMO lying on her back. Realizing that she was no longer buried alive, BMO sat up, blinked a couple times, and ran out of the room.

"I'm free!"

Cake looked at the little gadget scampering away and then at Fionna. "How long do you think she was under their?"

Fionna shook her head, "I have no idea." She stood up and wandered to the kitchen, "C'mon. I wanna go hang out with Flame Prince or something." She opened up the fridge and pulled out a piece of pie. Closing the fridge, she exclaimed, "We could go see Monochromicorn! Huh? Huh," She elbowed the air towards Cake, pushing her eyebrows up.

Cake rolled her eyes, "Uh-uh. You are not getting out of cleaning today. No matter how much I'd love to go see my man. And no matter how much you want to see your man."

Fionna laughed, almost spitting out a chunk of pie, "Hey, what's so wrong with liking FP?" She really liked him, but she always got embarrassed—and a bit defensive—when someone mentioned it.

"Nothing, nothing at all, but you need to stop trying to find distractions. CLEAN."

"Aw man," Fionna sighed with another mouthful of pie.

"Now go to the bathroom and start scrubbing the toilet or something."

"That's low, Cake. That's really low." She dragged her feet to the bathroom and looked around. She glared at the toilet. "You don't even look dirty." She shoved the rest of the pie in her mouth and opened the toilet up, "Oh, glob, never mind." Whilst scrubbing, she wondered why Cake was all of the sudden caring about how their house looked. She couldn't even remember a time when they cleaned at all. The most disconcerting fact was that Cake had woken up early to vacuum. Maybe she already planned to have Monochromicorn over later, and she was trying to not look like a slob. Whatever the reason, Fionna didn't like this.

After a couple minutes of half-hearted scrubbing, Fionna yelled to Cake, "Can I be done now?"

She heard a call back, "Not until that throne is sparkly clean!"

Fionna huffed and continued to scrub on her knees, until she heard a ghostly laugh. She scowled, having her guesses about just who exactly was in her bathroom. "Stuck cleaning toilets today, Fionna?"

The cooped up adventuress turned toward the doorway. "Marshall Lee. What are you doing here?" She interrogated, embarrassed. Fionna definitely did not want anyone seeing her doing such unthinkable things.

"Just looking for somewhere to hang, but I'm not about to clean, so I'll j—"

"No! I am so bored. I would feel bad ditching Cake, but I am going totes crazy in here, man," Fionna sounded exasperated and desperate in her voice. "Please?" She looked at Marshall with the best puppy-dog face she could manage.

Marshall stared at the crazy, blue eyes that seemed to be ready to pop if they got any bigger. He laughed; she had even pushed out a quivering bottom lip. "Okay, okay. But, because I am doing you this favor, you are to never make that face again."

Fionna's face bounced back to its original position with a giant smile, "Thank you! Thank you! Thank you," she exclaimed as she jumped up and landed right in front of him.

He put a finger to his lips, "Shhh."

"Oh, right," she whispered this time, not wanting Cake to hear.

"Alright let's go," Marshall wrapped an arm around Fionna, and they flew out of the bathroom window.

BMO popped her head out from behind the shower curtain, "Oh! Fionna is going to get kicked in her butt bones! Cake!" she ran out of the bathroom.
