"The dimly lit laboratory was filled with the hum of scientific innovation, casting sinister shadows on the walls and floor. Princess Bubblegum, known as PB, was hard at work on her latest invention. The glass vials bubbled and hissed around her as the scent of burning circuitry filled the air. Her hair, made of soft, malleable bubble gum, was pulled back into a messy bun and held by a purple ribbon. The tight-fitting lab coat accentuated her slender figure, each crease meticulously ironed as she bent over her workbench. The slight puff of a belly she’d started to develop showed just how much she’d been neglecting her fitness regimen, opting instead to immerse herself in her work.

“This will be a game changer,” she whispered to herself, as she soldered another connection onto her masterpiece. The contraption was a small, blaster-like device that could modify the body of any target it was pointed at. The holographic screen that hovered above the device glowed with possibilities, waiting for PB to test it out.

PB observed her surroundings, her dark eyes sparkling as they landed on a small potted plant on an adjacent table. The plant’s leaves were a vibrant green, almost pulsating with life, and PB couldn’t resist the temptation to test her invention on it. She aimed the device and muttered darkly, “Let’s see what you can do.”

A beam of light shot from the blaster, engulfing the entire plant. The screen displayed the words “Select Body part.” As PB scrolled past individual branches and leaves, she selected “Leaf” and turned a dial on her contraption. Before her very eyes, the targeted leaf began to grow exponentially, reaching new heights. She couldn’t contain her excitement and shouted, “YES! FINALLY!”

PB looked excitedly at her device. As usual, it was perfectly engineered to be as comfortable as it was efficient. Its blaster-like appearance added an element of dominance that sent shivers through her pink gum body. Her curiosity got the better of her as she wondered what it might feel like to modify her own body; the very thought sent an unexpected wave of heat through her.

Inhaling deeply, she picked up a mirror above her workbench and pointed the device at her reflection, selecting the words “Breast.” The holographic screen flashed briefly when a rush of exhilaration overcame her as she started to turn the dial. She watched with wide eyes as her small breasts began to grow, taking on a fuller, rounder shape that had her pink nipples at the peak of perfect gum flesh. She stepped back and admired her new form, running her hands over her newly enhanced breasts."

(Continue with "Pb comments that this will finally shut Marciline up that she is as flat as a board. She then looks at herself in the mirror, admiring the shape of her breasts, noticing that the machine made her nipples a lot bigger than it should have, she then questions if her nipples were always weirdly big. She shrugs it off and continues to scroll through the different items on her body, landing on hair, believing it to be the hair on her head, she says to herself "Making more gum to change my hair can be a pain- I mean, I know I can do it but, this is just quicker and more effecient. She continues by selecting the hair option, but rather than seeing her hair grow on her head, she feels an odd sensation under her arms. She lifts her arms up to see what had happened, revealing the once gummy stubble was turned into tendrils of long gum pit hair.")

Character:

• <Princess Bonnibel "Bonnie" Bubblegum (often called PB and occasionally Peebles, Bub-Bubs, or P-Bubs) is one of the main characters of the series Adventure Time. 

Princess Bubblegum is a sentient, humanoid-construct of pink gum, meaning her entire body is made up of pink bubble gum, including her hair. Her hair is soft and malleable. Although Princess Bubblegum appeared to be in her late teens, she is in fact much older than she looks. 

Princess Bubblegum is tall and slender with light pink skin and magenta-pink hair, which is made up of actual bubblegum. Her primary outfit is a floor-length, puffy-sleeved, dark-pink gown with a purple scoop-neck collar and sash around her waist and purple ballet flat shoes. Whenever she does any science experiments, she wears a lab coat, sometimes with her hair tied back in either a bun or a ponytail. However, she still changes her outfits and hairstyle regularly from episode to episode. 

Generally, PB is quite thin, her breasts are small, and her legs and thighs are quite skinny, although recently she has been slacking with her workout routine, so she does have a bit of a belly.

While Princess Bubblegum is typically kind, good-hearted and well-mannered, she can be very temperamental and has shown a malicious aspect of her personality whenever she is crossed. Even with her kind disposition, her moral code is not as strict as Finn's and there are also hints of a darker aspect of her personality. For example, she was shown randomly cutting the limbs off of tiny round creatures with scissors and reattaching them in different places when Finn sneaks in, although the creatures show no pain and seem perfectly happy to be reconfigured. Princess Bubblegum was also willing to resort to sabotage and forced sacrifice in order to survive. Her humor is also morbid and inappropriate at times, such as when Finn picks up a paralysis poison and she says, "That's paralyzing potion, Finn! Don't touch it, or it'll paralyze you forever!" and then giggles. There were also skeletons cuffed to the walls in a hidden chamber of her castle.

Bubblegum also adores the people of her kingdom and puts their safety above all else. In her dedication, she sometimes drives herself to exhaustion with her tasks. She is also a rational thinker with skepticism towards magic, labeling it as "scientific principles presented like mystical hoodoo." She also claims that "all magic is science," and Wizards just don't know what they're doing so they call it magic. She seems to regularly organize and attend events and showpieces such as scientific conferences, parties, and talent shows.

The ruler of the Candy Kingdom has to organize a thousand things at once, keeping a reliant and stable head at all times, lock down her own problems and struggles, whilst planning for the future protection of her people. Needless to say, none of this should be handled alone regardless of how mature or mentally strong the individual is. In addition to this, Bubblegum as a high-intellectual views things from a scientific or theoretical standpoint and structure things step by step. However, this often acts as a double-edged sword and complicates with the “perfection” role she has to fill already. If some unforeseen factor or miscalculation interrupts with her tightly detailed plans, she can be taken back for a moment and her insecurity reaches highest capacity. >
