The Temmies were an odd bunch, even for the standards of the Underground. Whilst most other monsters had a general place in this subterranean society, these silly cat-like creatures mostly stuck to themselves, at most wandering out of their village to scavenge for things tossed away in the dump. Such was the case when the village's "shopkeeper" was out looking for interesting things to grab

"Ooohh, SO prettE!!"

Her mind could hardly decide what she wanted to take back, she less so had a "train of thought" and more a "Mach 3 rollercoaster of thought", that was until something caught her eye, a little, cylindrical...thing made of aluminum, sticking out due to it shining against the crystals buried in the cavern walls.

"Ooo?!? Tem see...SHINY!"

Without even a second thought of what it was, she picked it up with a paw. It seemed to be some kind of hair spray, with the words "Funkyfast!" on its label, along with instructions for what it was and what it might do. Instructions that naturally, Temmie had no interest in reading. She fumbled with it and observed it curiously, poking and prodding at it until...
*PsssT!*
"BLEH!!! xwx"
...She sprayed herself with it, dropping it and scampering away after being startled.
...Something strange began to happen, as she wandered and vibrated her way back to the village, she began to feel...heavier, not in her gut, but on her head!

Looking up, her hair was...growing! ALOT! It was getting softer too! Curls and strands visibly growing denser and thicker, swirling like cotton candy being spun to slowly erase its' original shape in favor of a GIANT ball, even bigger than her head was! She was growing an afro, and a mighty impressive one at that!
"WHOAZ!! TeM's hair is HYOOGE!!"

That wasn't all, though! Underneath the striped shirt she wore, even more hair was growing from her torso. At first, it was only some strands, but then more...and more...and more came out, hairs intertwining and puffing out like the wool of a sheep to engulf her entire torso in fluff, forcing her stance upright before eventually engulfing her body entirely! Her afro and daruma grew larger, thicker, fluffier, and denser, until finally, they stopped, Now at over quadruple her original height, she simply stood there, awestruck at this new hair...~
"Tem..."
"Tem..."
"Tem feel TALL...and FuNKI!!~"
Just then, even more began to sprout!
Right below her nose, and right under her chin, hair began to sprout that was just as soft as her afros, but took on a completely different shape! The former grew to the sides, and the latter grew downward, steadily covering their portions of her face...she was growing a full on beard and mustache, and they felt wonderful! Her mustache became this huge, wide, curly handlebar, as her beard grew all thw way down to the cavern floor, curling at it's tips. Even her eyebrows joined in on the fun! Thickening and puffing up like dough in an oven, until they became one big unibrow!~
It all felt so incredible!~ All of this hair had become an incredibly comfy cushion for Temmie's entire body, having a soft, thick and pillowy quality to it, like she was laying in an incredibly soft bed with the world's puffiest pillow! It was especially warm as well, which helped with how cold Waterfall could be in places, and it dried off almost immediately whenever it got wet, too! It was as comfy as it was silly...but that wasn't the only pro!

After a few moments of bobbing and struggling, Temmie figured out how to move! With enough force, she could bounce and hop around in her afro daruma! Every time she went rather far, and her afros' wobbles made it worth it each time!
But that movement wasn't exclusive to her afro, her newfound mega-facial hair had its own uses! She could use her mustache like arms, curling it outward to grab whatever she found interesting, such as a comb for her afro, or various knick-knacks she would store away in her daruma for later~ As for her beard? She could whip it anywhere she wanted it to go! Not only serving wonderfully for self defense, but even being able to slingshot herself around! Letting her get around Waterfall in record pace!~

Temmies' mind was racing as always, she only used up just a little bit of the can when she sprayed it...~ and while it took her practically bouncing around the entire cavernous maze, before coming to a conclusion, it was one she personally LOVED!
Not only could she could share it with everyone else in the village, but she could make herself even BIGGER too!~

Thus, the Underground had just gotten its' "patient zero" for disco fever, and EVERYONE was gonna catch it~
