(I guess you could consider this an extension of this Taut-tober pic's story?? https://www.furaffinity.net/view/54072818/ :p )
=========================
Sometime between our clown-y rabbit friend bursting free into the world, and all of reality being engulfed by hyper-pressurized, engorged blimps, things had begun to change within the toy factory walls...~

Word had spread of Bunzo's exploits, a way to become stronger and eliminate the hunger that plagued them all at the same time. It had reached from the surface levels all the way down to the depths of the Playcare, suddenly, toys all over the factory were indulging in whatever they could find to fill up on...and the Smiling Critters were no exception~

Not to be confused with the Bigger Bodies experiment of the same name, a particular toy Catnap had taken on a "bigger body" of their own, purposefully suctioning up as much of their monstrous counterpart's gas as possible, they had become quite a blimp, not quite one of near-explosive proportions yet, but certainly puffy~ Standing around eight feet tall, it was a wonder he could move at all...and a wonder on what he did with his fellow toys, too, as all the swelling and newfound strength had only reinforced a VERY playful personality~

You might think it would have been easy to avoid them, what with the overwhelming smell of lavender wherever they went, and the massive purple sphere waddling around...but it was possible...and any who did, typically other critters like Catnap himself, tended to get some rather special treatment. Catnap would lock his mouth to theirs, and then blow and blow, giving them the kiss of a lifetime as the red fog spewed forth into them, if the rising pressure and swelling of every part of their bodies wasn't enough to put them into utter bliss, then the inherent sleep-inducing nature of the fog definitely would~

After that, who knows what he does with them?~ Whether he'd leave them be, swallow them whole, or even keep them around as kissable, taut playthings, one thing is for sure~
You're in for the coziest nap of you'll ever experience~

Sorry Poppy Playtime Chapter 3 made me a genuine fan of the game lol.
