A/N: This is the very first chapter of my very first fanfic! If you people like it, I'll write more! Enjoy(:

"Take that troll scum!" shouted Fionna, kicking the swamp troll in his up-turned nose. Fionna was currently kicking butt, and she rocked at kicking butt. The troll let out a thunderous roar and tipped backwards as Fionna landed her backflip next to her sister, Cake. Cake and Fionna ran to the edge of the cliff to watch it fall to it's death.

"Thank you Fionna!" sang Hotdog Prince as he waddled over. "I'm in debt to you for saving my people once again!" Fionna blushed as tons of little hotdog people made their way to her, shouting and climbing up her legs. Shaking them off, Fionna stepped out of the horde and jumped onto Cake's back.

"All in a days work HP!" yelled Fionna as Cake bounded off back to the treehouse. Clutching onto Cake's fluffy fur, Fionna smiled to herself. She loved being a hero. More importantly, she loved being the hero of Aaa.

"Ready to head home, or do you wanna visit the candy kingdom?" asked Cake, slowing down to talk to Fionna.

"Mm, let's head home, Cake. I really just wanna play BMA. Oh! Cake could you make bacon pancakes? I know it's not breakfast time, but I really want some!" exclaimed Fionna, hugging her sister's neck.

"Whatever you say, baby!" laughed Cake, heading for the treehouse visible in the distance.

Once inside the treehouse, Cake started on the bacon pancakes, her humming filling the kitchen floor of the treehouse. Fionna was up in their room, starring at the sunset. She remembered when she couldn't sleep one night because Ice Queen was dressed up as a poo brained horse as was staring at them through the window. Fionna smiled to herself, glad that night was over and done with.

"Fionna! Food's ready!" called Cake, the sound of clinking dishes reaching Fionna's ears. With a smile, Fionna jumped down into the kitchen, sounding out a loud "Hi-ya!" as she hit the floor and karate chopped at nothing in particular.

"Thanks, Cake!" exclaimed Fionna, settling into her spot at the table. BMA sat next to her, playing a stacato tune using her fork and the plate. Fionna smiled as Cake put the bacon pancakes onto all three plates and poured orange juice.

"Eat up!" commanded Cake as she took her own spot and began eating her food. BMA giggled and stabbed at her pancake with a fork before shoving it onto her face and sliding it around. Fionna shoved her mouth full of the delicious food and kicked her feet back and forth under the table. Suddenly, Cake's plate was lifted and dumped onto her head.

"Ah! What in the-" stammered Cake, slapping a pancake off her head. An all too familiar laugh filled the tree house and BMA jumped under the table, covering herself with a napkin.

"Marshall! What the fudge man?!" exclaimed Fionna, standing up in her spot as Marshall appeared, his invisibility power now gone. He was still laughing, floating in midair. Her face red, Fionna picked up a stick of butter and flung it at the vampire king, hitting him in the chest. With an oof, Marshall hit the ground.

"Hey, come on, that was funny." chuckled Marshall, floating into the air once more. Cake grumbled and rubbed of her face with a napkin, watching the vampire with weary eyes. Fionna rolled her eyes.

"Whatever Marshall! Get out, were trying to eat!" growled Fionna, folding her arms across her chest and puffing out her cheeks. Marshall layed in the air, folding his arms behind his head and closing his eyes.

"Well it looks like your done, Fi. Wanna come jack up the creatures of the night with me?" asked Marshall, opening an eye to peer at Fionna and hissing softly, his snake tounge slithering out of his mouth for a moment. Fionna pressed her lips together, thinking.

"Mm, baby, that doesn't sound like a good idea." warned Cake, standing up. "It's time for bed anyway." said the cat, eyeing Marshall, looking a bit too afraid. Marshall chuckled and his face transformed into a bat, one of the creatures he could turn into, and hissed at Cake. Cake's fur fluffed up and Fionna narrowed her eyes. But quickly, Marshall's face was back to breathtaking and he was floating upside down in front of Fionna.

"Come on Fionna, live a little." the vampire said with a wink. Fionna looked over at Cake.

"Just for a little while, Cake. I promise I'll be careful!" pleaded Fionna, looking at her sister with big blue eyes. Cake sighed and right when it looked like she was going to say yes, Marshall picked up Fionna by her arms and flew for the exit.

"B-Baby!" yelled Cake, still unsure.

"Thanks Cake!" called Fionna over her shoulder as Marshall flew the both of them out into the night.

"Ready to have some fun, good little girl?" asked Marshall, throwing her up into the air and catching her bridal style. Fionna let out a shout and clutched onto his shirt, laughing uneasily with a slight blush.

"Yeah, okay!" laughed Fionna, smiling up at the vampire king. He smiled back down at her and flew them over the candy kingdom. "Oh, I hope were not gonna mess with the candy people are we Marshall?" Fionna asked. But Marshall only smirked and continued their desent.

Landing, Marhsall plucked off her hat, revealing her long blonde hair. And before Fionna could protest he ruffled it up, causing Fionna to go red-faced again.

"Marshall, give me back my hat!" complained Fionna, trying to jump up and reach the floating boy. He laughed and threw it on the roof of a candy house. "Marshall!" growled Fionna, clenching her hands into fists.

"You really are adorable when your angry, Fi." said the king with a wink, causing Fionna to blush. "But we'll come get your hat later, right now it's time to scare the gum out of the candy people!" he hissed with an evil laugh, his fangs glinting in the moonlight. Fionna rolled her eyes. "And your not very scary, so were gonna have to get you dressed for the part." explained Marshall, picking up dirt from the alley and smearing it on Fionna's round face. Spitting out some dirt, Fionna laughed with the vampire, shoving him away.

"I'm pleanty scary!" argued Fionna, growling and curling her fingers like claws. Marshall spun in the air and held his gut, laughing at her attempt. Fionna furrowed her brow and put her hands on her hips, not amused.

"Well, you'll be with me, so maybe we'll get some gum out of the people." laughed Marshall, grabbing her by the wrist and dragging her to the edge of the alley. "Now we wait..." he said softly, licking his lips. They only had to wait for a few minutes before Cinnamon Bun came skipped down the street. Marshall Lee smiled over at Fionna and nodded, then counted down softly from three to one. On three they both came barreling out of the alley, their scariest faces on.

"Dear glob!" shouted Cinnamon Bun, fainting on the spot. Marshall collapsed to the ground, laughing, and before long, Fionna was on the ground with him too, holding her gut.

Before the night was over, the two had messed with quite a few of the candy people, and Fionna found it actually really fun. Flying her back home, Marshall was quiet. Fionna smiled when the tree house came into view. She was super tired.

"Thanks for the fun, Marshall Lee." yawned Fionna as he set her down by the door. Marshall nodded, his crooked smile revealing a fang.

"No problem, Fionna. Thank you." he smiled and floated higher into the dark sky. "See you later, heroine of Aaa!" he called before flying off to who knew where. Fionna smiled to herself and quietly made her way inside, not wanting to wake anyone. She still had a few hours to sleep, and she was going to make the best of them. Slipping into first her pajamas and then her bed, Fionna fell asleep quickly, her mind content.
