(WOW this is an obscure pick, hope you all like it tho!~)

Nine nights of nonstop tautness! Tonight we take on a being in a similar vein to last night and night 4's taut-tober blimps, albeit one from the opposite of the globe!

In Japan roughly thirty or so years into the future from now, executives and engineers alike prepare for an ENORMOUS change to the country's premiere theme park "Sato Wonderland". The park's main feature was it's incredibly lifelike animatronics, able to respond and react near-perfectly...yet there was a flaw with them. There was simply too many attendees for them to get to!

...There were two options, either create more copies of the existing animatronics and risk breaking the illusion...or find a way to let the animatronics address more people at once! The latter was chosen, and a brilliant yet bizarre idea was made~

They called it the "party-sizing initiative", the goal being to upscale the animatronics to such a degree that they could easily entertain over a dozen attendees at the same time! This was first tested on the flagship mascot of the park, a cute spirit fox by the name of Kitsuhime~ After her outer shell was made far stretchier, it began~ She was filled to the brim with soft, pillowy, fluff-like foam. Her form swelling into a ridiculous, round, twenty feet tall BLIMP that resembled a goofy caricature of her original self, with the foam spreading in such a way that it caused her to become somewhat uneven, with one eyeball remaining round, and the other jutting out like a balloony torpedo~ Of course, Kitsuhime didn't mind one bit! The more children who she could make happy, the better...even if that meant being potentially used like a bouncy castle~

After a successful testing period using a chosen focus group, the initiative was approved to be applied to all of the animatronics in the park! Yet...one thing still remained as a concern. As the world's population would continue to rise exponentially...eventually there would be so many visitors that even these new "party-sized" bots wouldn't be enough...~

...Of course, it was decided that every so often, the foam within would expand further, automatically causing them to be doubled in size to compensate, even without human intervention!~ Granted...there WAS the possibility of that too becoming exponential, eventually leading to the mascot's outgrowing the park, and eventually the planet...but that was a bridge they would cross when they get to it~

...spoiler warning, they never did~
=======================================
Hope this one was still good, even if the character is hella obscure, I just find them adorable and wanted to do something for them, considering how little weird art exists for them :p
