I do not own Adventure time, that would be Pendleton Ward :)

RxR and Hopefully it's not too crappy.

Soft chirps were heard as Fionna tiredly walked through the front door of the tree house. She turned her sore body around and stared out the front door. Sunlight sprang up over the hill to greet her straight in the face. She squinted and let out a long sigh before reaching out and closing the door. She slowly kicked off her shoes by the front door and made her way over to the ladder that lead up to her bedroom, listening to the sounds of the birds getting louder and ever more obnoxious. Her muscles ached as she made her way up the ladder and by the time she reached the top, she was almost ready to just pass out on the floor, but somehow she had managed to stumble over to her bed before promptly letting herself fall ungraciously on the soft covers. She rolled over and a beam of light hit her eyes causing the exhausted blonde to groan in frustration. Fionna grabbed one of the two pillows she kept on her bed for this very reason and tossed it over her face, blocking out light and half of the sound of the outside world. She closed her eyes and went over the mission that Prince Gumball had given her in her head.

Fionna raced over the hills and jumped over the small puddles that had been left behind by the rainstorm the night before. She had a smile plastered on her face not only because Prince Gumball had entrusted her yet another silly quest, but because she loved doing those quests. Fionna was the ultimate adventuress and loved to take on hard and daunting tasks even if it meant it could ultimately cost her life. She raced through the entrance to the forest, dodging low hanging branches and fallen trees caused by lightning strikes or other monsters that roamed in the enchanted woods. Upon the thoughts of fight entering her mind her heart raced even more so than it had been and the smile grew wider. She finally came to a halt at the threshold of a cave. Fionna had been here several times, but she knew that when she slayed one monster, others took residence in the old dwelling. It didn't bother her any, it just made her job easier seeing as how she didn't like being away from home for too long. Cake didn't like it either. Cake was more motherly to her then she normally cared to admit, but she had balanced it out well through the years that they had known each other. Cake of course didn't come with her this time because she and Monochromicorn had planned a day away from it all. They'd had a lot of those lately and Fionna smiled at the thought of her best friends' relationship getting so serious. She, of course, was only thirteen and had only just hit puberty. She didn't have time to think of boys, she didn't even find any that had even crossed the line of "friend". At one point she thought she had, but after the Ice queen had impersonated Gumball she hadn't really set her eyes on anyone. Lack of trust was her excuse. Her feet hitting the cobbled cave ground pulled her out of her wandering thoughts. Piercing blue eyes scanned the darkness as her right hand slipped quietly into her backpack to grab her crystal sword. After taking a few more steps into the silence a shuffle made her stop. She crouched down into a defensive stance and cautiously tiptoed forward until she pounced on what she had thought was the beast. Instead a very audible curse was uttered as she had ambushed a very surprised human…or as close to it as could be found out in the forest.

"Hey Fi…didn't know you missed me that much" Wheezed the Vampire king. Fionna blinked then glared at him, making her cheeks puff up in that adorable hamster-ish way.

"Marshall Lee? What're you doing here in this cave?!" She huffed loudly as her pale arms crossed angrily over her chest. The only response she got from the other party was a sly smile with a small fang poking out of one side. Fionna sighed and got to her feet. Her knees had landed in his diaphragm and even though he didn't actually breath, it hadn't felt good. In fact, it had still hurt him to the point where he had to rasp to talk to her, although her standing up made him feel better. She offered him a small, slightly calloused hand as a gesture of apology. Marshall hooked his hand in hers and pulled himself up. It always astonished him at how strong Fionna actually was. Anybody else would have swayed at the momentum of him pulling himself up, but not her. She may have looked small and timid, but she was anything but that. And that's why he admired her. She could hold her own and nobody other than the people that knew her would know the difference.

"So, what're you doing in this cave? Last I checked you lived in a tree" he chuckled at the last part of his own joke. Fionna on the other hand didn't.

"I came here to kill the sludgma…Sludgy…the sludge thing and get some of its gross ooze for GB" She told him starting to look around the cave again. Marshall Lee floated off the ground and crossed his legs.

"Oh, that thing, It's dead already…I killed it about an hour ago" he said nonchalantly looking at the signature bunny hat that adorned the top of the blondes head. His eyes widened as she spun on her heels.

"What the Glob Marshall!?" She was glaring at him again, and this time she was actually annoyed "Where is it? I need it for GB or he's not going to be happy…" she explained walking over to the floating teen. He glared at her in slight annoyance but motioned for her to follow him.

"It's this way…and I'm sorry, if I had known you were going to be going on another one of Gum wads adventures, then I wouldn't have touched it." His words ceased as he pointed to a giant mutant slug looking thing with horns and giant sharp teeth covered in teal colored ooze. Fionna scrunched up her nose at the smell.

"This is why I will never ask Gumball what he does with all these things" she stated giving off a small laugh. Marshall chuckled as well. They're eyes met and they blinked at each other at the awkward silence that had befallen them. Marshall broke the silence by looking away and coughing.

"So, I'm gonna go" he said quickly. Fionna simply nodded.

"Thanks for the sludge" she said holding up a jar filled with the ooze that Prince Gumball had wanted. Marshall cringed.

"You're welcome and Gum-dorks welcome too" and with that, Marshall flew out of the cave. Fionna watched him go, and then looked back down at the jar.

"He sure is weird sometimes…" she quietly told herself. She stuffed the jar into her pack and made her way towards the mouth of the cave. She didn't make it that far before night had descended and she was fighting her way through all sorts of weird creatures that could only be found in AAA. By the time she had gotten to the top of the hill that overlooked her house, she had been badly beaten, was horribly dirty and didn't feel like delivering the ooze until she had gotten a proper nights rest and a good hot shower.

Fionna's eyes finally shut after recounting her day in her head. She had snapped at Marshall about killing the sludge whatever and then had at one point almost needed his help just trying to get out of the forest. She decided before she allowed her eyelids to flutter closed, that she would need to apologize later to Marshall lee for being such a pa-toot.

Fionna awoke some time later to the sound of Cake laughing. She sat up in bed and stretched, then winced after feeling the stinging pain in her ribs and back were still there. She lowered her arms slowly and looked outside. Darkness was all that greeted her. She let out a small sigh before slipping the covers off of her and experimentally putting her feet on the floor before standing up. Waves of fatigue and soreness ran through her and she had to all but crawl to the bathroom. She had been like this before, hell, she'd been worse then this before! All she had to do was withstand this for another day or two, do some stretches and the pain would be gone.

The girl staring back at her from the mirror was filthy. The once blonde hair was a shade shy of brown, there were spots where blood and other gross things had splattered and stuck clumps of hair together. Her casual blue shirt was ripped in places and just dirty in others and her skirt didn't look much better.

"How're you feeling sugar?" were the words that made Fionna jump. She looked at the door and the small white and brown cat was standing there looking concerned. Fionna smiled at Cake, she had missed her on her adventure the night before, but she knew that Cake had spent time with Monochromicorn and that she had enjoyed herself.

"I'm okay. I think I could be a bit better though...how about you? How're you doing?" she asked Cake. She cringed as she touched a gash on her cheek.

"I'm doing great baby! Me and Mono, y'know we were just hanging out and then he popped the question!" She wiggled her arms and her eyes got big with excitement. Fionna's eyes widened as well.

"He asked you to marry him?!" Cakes arms went down and she laughed.

"Heck no! He asked me to be his girlfriend!" Fionna's expression went to a blank and she shook her head in response. Cake looked her up and down "Need anything else girl?" Fionna smiled at her.

"Nah, it's cool. I'm just gonna take a bath and then go see Prince Gumball. Give him his ooze" She said motioning to her backpack. Cake walked over and pulled out the cold glass jar that swirled and made a squishing noise.

"That's nasty! Glad I wasn't there for this one, wouldn't want to gunk up my fur" she told Fionna playfully petting her tail. Fionna laughed once more before closing the door and gingerly stripping out of her clothes. After shoving them down the clothes shoot she turned on the hot water, put in some lavender oil to help calm her muscles and got into the bath.

After about an hour or so, Fionna climbed ungraciously out of the tub and wrapped a towel that almost wrapped around her small frame twice under her arms. She went out into the bedroom, quickly threw on another outfit that matched her other one exactly and scooped up her backpack ready to head out into the night towards the candy kingdom. Cake stepped out the door and without a word expanded to enormous proportions. Fionna stepped into her hand and Cake gently set her down on her back, the fur almost hiding her completely.

They arrived at the bubbly pink candy kingdom and the scent of sweets and sugar filled her nose. Cake shrunk down to her normal cat size as they stepped foot in front of the two heavy double doors. Fionna always had special permission to just walk in whenever she wanted; the guards on either side of the door never stopped her, even though she doubted they really could. She pushed open the doors and walked into the grand foyer where Prince Gumball was standing talking to his peppermint maid. Upon seeing Fionna enter she bowed and walked into the back disappearing behind a door. Gumball looked up at Fionna as she waved to him. His eyes narrowed slightly and he walked over to her, his fists firmly planted on his hips.

"Fionna, I give you missions for a reason! I needed that slime yesterday so I could ship out the gummies to the Tufruts!" He shook his head in disappointment "I'll have to explain to their ambassador about the delay" Fionna stood there silently in disbelief. She had gone to lengths to get him his slime, and here he was in front of her saying she could've come home yesterday? After she still felt like butt today? Fionna's eyes narrowed at him and she yanked the heavy jar out of her pack and tossed it to him.

"Fine, here. I'm sorry your majesty!" She hissed back "Come on Cake, let's go home" Gumball blinked as Fionna turned her back on him to walk out the door. His eyes slowly made their way to Cake who just glared and shook her head.

"Not cool baby, not cool" She too turned and walked towards the door with Fionna, and with that they were gone.

Fionna wanted to cry. Gumball was one of her best friends and that's why she went and did his silly missions for him, but this was the last time he was going to be ungrateful. She hated when he did this, just because he was a prince didn't give him the right to act like she was one of his servents. She buried her face in Cakes soft fur and silently slammed her fist into Gumballs face over and over in her head. Cake craned her head to look back at her friend. Instead of trying to talk she just left it to silence for the rest of the walk home.

As they approached the house Fionna climbed off Cakes back and walked silently into the house. Cake quietly followed until Fionna whipped around and looked at her.

"What would he do if I wasn't here to get him his junk?!" she shouted. Cakes fur frizzed up in surprise, but slowly went down as she listened to Fionna rant. "What if I wanted to go on my own adventure? I've been going to get everything he's wanted for years!" She finished with a sigh and she sat down on the couch "but it doesn't matter, nothing like that's going to happen…." Cake popped up, giving Fionna a reassuring smile.

"You never know! We could sent off to another part of AAA and discover a lot of different stuff!" She exclaimed, her fur was now puffy with excitement. This made Fionna smile. She knew her friend would now be looking out for a new adventure to go on, somewhere they hadn't traveled yet.

"Yeah, but until that day comes, I guess it's back to the boring old routine" she sighed.
