It was the average summer day in the Candy Kingdom. The temperature seemed to rise everyday, which of course brought in uncomfortable humidity along with it. Not that this was an issue to the average citizen, which was made of candy, and therefore wouldn't wear clothes. However, problems arose with the nation's ruler, Princess Bubblegum.
"No, no, no!" the princess screamed in frustration. "This won't work! There's no way I can let any peeps see me wearing this!"
"What is it this time?" her peppermint butler asked from down the hall. "I'm sure whatever you want to wear is perfectly acceptable, and you're simply overreacting."
As he made his way towards the castle's expansive wardrobe, the princess replied, "But you just don't understand! This whole outfit is totally ruined by... well, just look!" Peppermint Butler arrived at the doorway, and peered over at the princess, trying to deduce the apparent complication. There was nothing that seemed to be problematic with her attire, as she was wearing a simple jean shorts and crop top combo. In fact, the style was reminiscent of a teenager from several centuries ago.
"I can't seem to find any issue with what you're wearing." he concluded. "In fact, it's mostly straightforward. Possibly 'totes on fleek', or whatever it is you say." She sighed in irritation.
"You're missing the point. Look!" she stated, while motioning to her bare midriff.
The butler squinted. "Looks fine to me." he said.
"Do I really have to spell it out for you?" said the princess. "This whole outfit would work perfectly, if it wasn't for the fact that I have no belly button!"
Peppermint Butler raised an eyebrow. "Of course you don't, you're not a human. What's the big deal about that?" he asked.
"The whole thing just looks weird, it's incomplete!" she answered. "I can't instill pride in the spirits of every citizen with this!"
The butler sighed. "If you wish, perhaps I can ask one of my... associates,and see if any of them can provide a solution. " he said.
"Ugh, you know I don't believe in any of that mystical flubby-doo!" she replied, with a scowl. "There's no way I'm letting one of your weirdo friends mess with my stuff!"
"In that case, I believe your issue is unsolvable." he said, with slight disappointment. "It is impossible to help you without the assistance of the supernatural."
"Oh, come on! There has to be someone who could give a belly button!" she whined. "Can't you, like, look for someone trustworthy that can do that?"
He sighed. "Where, exactly, am I supposed to find someone who could?"
The princess pondered for a second, before responding, "Check the archive! There are some old phonebooks and things there. Something there has to help!"
"Alright, whatever will make you happy." he replied, while exiting toward's the castle's basement.
Almost 2 hours have gone by, and the peppermint butler has yet to find anything that could help the princess. Not that he expected to find a flyer advertising a belly button surgeon or anything, but it seemed that every phonebook he looked over contained absolutely nothing useful in this situation. All that was left was a single tattered book that seemed to be 150 years old.
"Might as well check this last one." the butler muttered under his breath. Dust flew off the cover as he put the large book upon the desk and flipped through the pages. The A section was mostly fruitless, but he had different luck within the B's. About halfway down the page was a small text advertisement that stated: Want to have some navel fun? Just give a call to the Belly Button Queen! 555-867-5309.
"I don't believe it." he mumbled. "Oh well, hopefully the number still works." he thought, as he brought the book upstairs.
Being immortal had its disadvantages. Most days, there was nothing to do. Marceline was floating over her couch, practicing the same few chords repeatedly. She mindlessly strummed the bass, mainly just to kill time. The only interruption came in the form of a sound she has not heard in several decades: the noise of her old landline phone ringing.
"Weird, I thought that thing broke 40 years ago." she said to herself, while levitating over to the antique phone. She picked up the receiver, and answered with a confused "Hello?"
"Marceline? Is that you?" asked the butler on the other end.
"Pep-But? Why are you calling my old number?" she questioned.
"You see, Princess Bubblegum is in need of some... unusual assistance." he answered. "She says that she desperately needs a belly button, and asked me to find someone to give her one."
Marceline's cheeks began to flush. "But why did you call me?"
"I was looking through some old phonebooks, I found an advertisement for a 'Belly Button Queen'." he explained. "It was the only thing I found that could possibly help her. You are this 'queen', correct?"
"Well, I was, but that was a long time ago!" she said, sweat lining her brow.
Peppermint Butler sighed. "Look, can you just come over to the castle and see what you can do? The princess can be very adamant when it comes to this sort of thing, I would probably never hear the end of it if you do not at least try to help.
After thinking for a moment, she replied, "Fine, I'll see what I can do."
"Great, I hope you can help the princess." he said, before hanging up.
"Oh glob, I can't believe I'm doing this." she said, rubbing her forehead. It has been years since she's taken on this persona, though it was for different reasons. Her belly button kink led to some desperation in the past, but that was all behind her. Now, she was doing this for reasons other than quenching lust. She was helping a friend, albeit for bizarre reasons.
Marceline went over to her closet, and dug out the old "uniform" buried deep within. It was a tattered and stained t-shirt, with the words "Push Button for Service" printed on it, along with an arrow pointing to a hole cut to expose her navel. It didn't quite fit her anymore, with an additional line of pale skin showing between her shirt and pants.
"But hey, the more belly, the better, right?" she said to herself, as she made her way to the door.
"But why Marcy?" asked the princess. "This doesn't seem to be something she would do."
"I do not know why Marceline has had such a strange occupation in the past, nor do I know why she abandoned it, but she has agreed to assist you." the butler explained.
"Whatever. I need all the help I can get." she said. Almost on cue, Marceline flew through the open window at the top of the castle's tower.
"Marceline, the Belly Button Queen, at your service!" she loudly announced.
"Can you at least knock next time?" said the princess, unamused. "I'm so sick of you arriving like this!"
"Fear not, Bonnibel, for I am here to dispel your navel troubles once and for all!" she said, ignoring the princess. "From this day forward, you shall never have to deal with..."
"Yeah, yeah, I get it." the princess interrupted. "So, why exactly are you doing this?"
Marceline continued, "You see, the belly button has an unappreciated complexity, creating one is more difficult than just making a small hole. If you will kindly observe." she said, motioning to her own uncovered navel. The princess squinted, and gazed at the vampire's shallow innie. It was quite intricate, being filled with tiny wrinkles and folds.
"Huh, never thought about that." said the princess, furrowing her brow.
"As you can see, belly button creation is not simple. This is why my job is rare." said Marceline. "So, will you accept?"
"Well, if it completes my outfit, of course I will!" answered the princess.
Marceline smirked. "In that case, push the button for service!"
"All right, whatever you want." said Princess Bubblegum, snickering. She reached out and poked Marceline squarely in the navel, hard enough to make a tinge of excitement jolt up her spine. She hasn't been touched like that in a long time. "So, where do we start?" asked the princess.
"First, let me get a feel of what I'm working with." answered the vampire, bringing shaking hands up to the pink stomach. She rubbed the sugary flesh, giving it a slight squeeze. A minute seemed to go by before Bubblegum became impatient.
"So... what do you think?" she asked. Marceline seemed to take an extra few seconds to savor this midriff rubbing, before replying.
"Hmm... well, it's very soft... and definitely malleable." she said, removing her hands. "So, what kind of belly button do you want?"
"I didn't know there were different kinds of belly buttons." the princess responded. "What are my options?"
"Well, there are innies, which are pretty much holes in your stomach. Take my innie, for example." explained the vampire, gesturing to her own umbilicus. "But there are also outies, which are like little knobs of skin that stick out."
Princess Bubblegum rubbed her chin, replying, "In that case, let's start simple and try making an innie."
"Okay. I'll try a few different methods and see which one works best." Marceline explained. "First, let's try a simple poke." she said, taking her finger and pressing hard into the center of the princess's smooth midriff, letting it sink in. She removed the finger, and examined the indentation. "I don't know, this just doesn't look very natural. The hole is misshapen, and my fingerprint doesn't really match the details you would find in a belly button." she concluded.
"So, a reject? No biggie." said the princess, before tensing her whole body, and somehow making the hole morph back into its original shape.
"Whoa, I didn't know you could do that!" said the vampire. "That makes this so much easier!"
The princess rubbed her forearm and looked down, saying, "Yeah, but I don't really like doing it in public..."
Marceline squinted. "Right... Anyway, let's try some other techniques. Got any pens?"
"No! It still doesn't look right!" the vampire yelled in exasperation. She angrily threw the toothbrush at the pile of rejected tools.
"I think that's the last of 'em" the princess said despondently.
Marceline shrugged. "Well, I'm sorry, but I don't have any more ideas. I guess I can't just make you a belly button."
"Hmm... Well, I have one more idea, I think we should try it." said Princess Bubblegum, slightly more hopeful. Before Marceline could even ask what that meant, the princess suddenly went over and pressed their stomachs together. The vampire's eyes widened in surprise, and she quivered at the feeling of Bubblegum's warm midriff pressed against hers. That feeling only heightened when she felt the princess's soft flesh unexpectedly jut out and fill the entirety of her navel. They stayed like that for a few seconds, before the two separated. Present within the center of Princess Bubblegum's pink abdomen was an outie, molded to be the exact opposite of Marceline's innie.
"Pretty smart idea, huh? Using another belly button as a mold?" the princess said, with pride.
"Uh, y-yeah, that was p-pretty c-creative." responded the vampire, visibly embarrassed.
Bubblegum went over to the mirror and examined her newly created outie. "Wow, it looks great! I think it works better than an innie for me. Goes perfectly with my outfit! Whaddya think, Marcy?"
Marceline stammered, "Of c-course, it's... it's g-great."
The princess turned around, her face becoming slightly more serious. "So, uh, what's this gonna cost me?"
"S-since we're s-such great f-friends, it's f-free of ch-charge for you." the vampire answered.
The brightness returned the Bubblegum's face. "Nice! Well, thanks for your help. I hope you get business in the future!"
"Y-you t-too." Marceline stuttered, before awkwardly flying out the open window.
"There, that should do it." the vampire muttered to herself, as she put the finishing touches on her billboard. She flew backwards, getting a view to admire her work. Sure, it was placed just outside the kingdom, next to a road seldom traveled. But hey, it was cheap to make. On the sign was bold lettering, stating: Navelless? Need an umbilical beauty mark? Just give a call to Marceline the Belly Button Queen! 555-867-5309.
"This is totally gonna get me some customers."
