Here's a fic idea: Vriska goes through an exaggerated 'toon' tf. Short, ridiculous curves, rubbery limbs, etc. there's no mental tf, but nobody can take her seriously as her boobs wobble around like they have minds of their own. Possibly with lactation or embarrassing sound effects that follow her around.
Vriska, while out treasure hunting came across the fabled fountain of Luck, well, she thought it was at least, however upon entering its waters the truth was more awkward than the legends would have told her. The fountain wasn’t a fountain of luck or even a fountain of anything reasonable, it was actually pool of cursed artistic ichor. A liquid that if swallowed would change someone irreversibly.
Vriska didn’t notice it at the time, but the once she was submerged, she began to change, her appearance and being shrinking and inflating, her body tingling all over as she looked more and more “animated”. Vriska’s curves swelling out and growing as her flexibility increased countless fold. Vriska’s flexibility rivaling that of a rubber hose by the time the changes finished.
When she climbed out the ichors she discovered the result of the transformation, when she heard a boing like noise coming from her now impossibly large chest, the sound happening at various levels with each movement she took which only increased her frustration and embarrassment as she heard a cartoon stretching noise before a “pedoing!” noise as she saw her breasts trying for force their way up through the neck hole of her shirt.
An embarrassing journey home accompanied with the noises didn’t help either, her whole body was jiggling and making noise, how could anyone take her seriously now? That was one of the unluckiest days she’d ever had!
