Pff, I just realized how lame this is or whatever. Especially Marshall-Lee's singing. I totally added some parts and hinted at the chemistry between Gumball and Marshall... Maybe a hint at some later fics? I really based their personalities off of their counterparts because I feel I'll portray them better... Oops. Cake's "rock 'n roll" appearance wasn't originally written in... but maybe I added it? Anyway, here this is. By the way, check out Ashetoashesjc on youtube for the cover of "I'm just your problem" that is sung here. It's my headcanon voice and also, my favorite cover! :) I'll watch the episode one more time and try to get the final update out; I pretty much finished it already, just haven't cranked out the ending yet...


She sighed, pressing her forehead against the wooden surface. A quiet, twinkly sort of sound could be heard. "What?" Fionna questioned, lifting her head to look up at the arched door in front of her, which began to form rough words carved into the stone in a small golden light.

"This door shall yield to no command, save for a song from a genuine band?" Fionna read, squinting her eyes as she watched the words come to a stop at the end of the arch. Marshall Lee and Gumball simply stood behind Fionna, watching wordlessly. After Fionna had read it completely, she threw her hands into the air in aggravation. "What is this gribblegrab!" She shouted, and Gumball came up behind her, an emotionless expression on his face.

"It's the door of the Door Lord, Fionna," He said, matter-of-factly, gesturing towards the large structure. "We used to lock them up, but they kept escaping… Because they're Door Lords. Or ladies… in this case." He balled his hand into a fist and beat it in the palm of the other.

Marshall Lee, who floated beside Gumball, had grabbed himself a sun hat to keep from burning from the light. He smirked at Gumball, biting the soft skin of his lip. "They keep escaping because you let them live." He chuckled, resulting in a growl and a glare from Gumball himself. Cake rolled her eyes at the two's behavior. They were almost always this way around each other. Fionna didn't seem to be paying attention at the moment.

"Hmm…" Fionna began to think, one hand rubbing her chin thoughtfully. "So," She began, looking back up. "The door said it would open for a genuine band. Let's try to music this door open as a quintet!" She concluded, excitedly jumping up and waving her hand to all four of her friends.

"Can I be the jerk in the band?" Cake asked, a grumpy expression coming over her face. "'Cause the jerk is an important part of the band's success. Hmph." Cake's form had changed from her normal, plump cat self to a form somewhat like a human, but curvy, with spiked hair that reminded Fionna a bit of when Marshall shaved his head on one side.

"I know how to get through this door," Marshall Lee smirked, strumming a chord on his guitar, closing his eyes to listen to the rhythm. "We're gonna lay down a chill jam, you know what I'm sayin', girl?" He asked Fionna, floating around her in a small circle. The younger of the group cheered.

"Hey, yeah, yeah yeah!" She pumped her fist into the air, while Cake searched her backpack for her violin, pulling it out with ease as Fionna had paid her little mind.

"Just keep it cool. 'Kay, Prince?" Marhsall opened one of his eyes to look down at the bubble gum pink prince, who crossed his arm and made a 'hmph' sound with his lips. Marshall continued to strum a few chords, laughing a little at the Prince's reaction.

The Prince quickly grabbed BMO, snatching them roughly and pulling the plate covering their face off in one tug. "Oh, my face!" BMO said in surprise, looking up at Gumball as he laid the machine on his lap and began to press their buttons, making the machine giggle.

"Let's see if you hacks can keep up with my raw talent!" Cake chanted, laying her bow onto her violin strings as she began to strum. "Ha!" Fionna began to beat box, waving her hands with every noise she made, while Marshall had begun to strum and sing.

Marshall always had a pretty voice, one that many people took a liking to. It was understandable, he was a handsome vampire, and even a little arrogant sometimes, which attracted others like a magnet. But he never bothered with any of them.

"La da da da da," Marshall rose into the air, strumming his guitar with care while he closed his eyes, simply listening to the music. "I'm gonna bury you in the ground, lada da da da, I'm gonna bury you with my sound," He sang, causing Gumball's expression to become a bit uncomfortable, while Fionna seemed to be enjoying it. "I'm gonna drink the red, from your pretty pink face, I'm gonna-"

"Marshall Lee, that's too distasteful!" He shrieked, a red blush crossing over his cheeks by the wording of the song, and not too much the song or singing itself. What was he meaning by those lyrics?

But what was on Marshall's mind, was what was he meaning by that statement? Furthermore, why did he always, somehow, manage to get on the candy prince's damn nerves somehow? What did he even do wrong this time? Why was he always doing something wrong? "Oh, you don't like that? Or do you just not like me?!" He snapped at the other, his expression showing he was hurt as he floated back, the tone of his voice suddenly changing from being light and airy to a bit passionate… unintentionally so, of course.

"Sorry I don't treat you like a God, is that what you want me to do?" He asked the prince, face turned away. Fionna and Cake stared, eyes wide, unmoving. "Sorry I don't treat you like you're… perfect! Like all your loyal subjects do, sorry I'm not made of sugar," He sang, resulting in a very obvious blush and stunned silence from Gumball, who was only blinking at him, mouth agape. "and I'm not sweet enough for you,"

Despite how the three felt about the song, the door behind them seemed to be enjoying it. The smiling mouths that covered it were glowing, smiling wider, happier.

Marshall Lee seemed to be getting angrier, maybe even teared up a little. He began to walk atop the door, strumming his guitar. "Is that why you always avoid me? I must be such an inconvenience to you, well, I'm just your problem, I'm just your problem…" He seemed to sigh, and shake his head. "It's like I'm not… even a person, am I?" He met eyes for a moment with Gumball, before turning away. "I'm just your problem…"

Momentarily, Gumball felt that sort of aching pain you get in your heart when you've been scolded after you've done something wrong, maybe even a feeling of guilt. What did that mean, anyway? He was anything but a problem, at least in that way. Fionna and cake certainly felt the same way.

"Well, I-I-I shouldn't have to justify what I do, I-I-I shouldn't have to prove anything to you," Marshall continued. "I'm sorry that I exist, I forget what landed me on your blacklist but I-I-I shouldn't have to be the one that makes up with you so,"

Fionna pointed to the glowing door, a smile on her face. "Look, the door!" She told Gumball, who took a moment to snap back to reality and stare at the door, eyebrow lifted.

"Why do I want to? Why do I want to? I don't have a clue, so why do I want to?" Marshall stared off into the distance, seeming frustrated again. "I'm sorry that it's this way, I don't know what else to say. 'Cuz I-I-I didn't mean to push all my friends away-"

He switched his gaze to the others, suddenly becoming a bit flustered. "And I-I wanna- Bury you in the ground, and drink the blood from your…? Ugh. You messed me up!" He snapped at Gumball, "Why are you looking at me like that?!"

The door then began to shrink away and frown again, and Fionna shook her head. "No everybody, don't stop now!" She yelled in the boy's direction. "The door was responding to it! To our music!" She stood back, rubbing her chin again. "I wonder what it liked. Or what was missing!"

"I know what was missing. Talent!" Cake yelled, throwing her hands in the air. "Hacks, talentless hacks, I'm out of here!"

"Yikes." Marshall Lee mumbled as Cake walked away, staring down at Fionna, his nerves now at ease.

"Maybe to be a more genuine band, we need to hang out as buds, and have a noodle break…" She reached behind her to grab out a hard, uncooked square of ramen from her bag, which she'd already gone to take a bite from. "C'mon, it'll help," She gestured it towards the boys, nodding her head with a smile.

Marshall began to float away, and Fionna frowned. "No, don't go too!"

"I'm just getting something to cook that with?" He laughed, and Fionna looked a little confused.
