Frisk was at the playground with Muffet, on a nice sunny day. Frisk soon spotted their favorite piece of playground equipment, the see-saw.
Sitting on one end of the see saw, Frisk called Muffet over. Muffet tapped some ash from her cigar into a nearby trash can before walking over.
Muffet giggled and said "Well, well dearie, returning to an old favorite are we? Very well."
Muffet took a seat at the other end of the seesaw, raising it up before quickly dropping herself down on it.
A metallic "SPROING!" filled the air as Frisk was catapulted high into the sky. They laughed and did a backflip in mid-air as they soared into the sky, confusing a few birds who were flying nearby. Frisk then tucked into a cannonball as they plummeted back to earth and towards Muffet, who looked on happily with her mouth slightly open.
However, Frisk ended up accidentally landing directly landing into Muffet's mouth, who reflexively swallowed them whole in a single gulp.
Muffet looked down with only mild surprise at her distended belly, giving it a poke. Frisk had landed in Muffet's dark and somewhat cramped stomach, which had a few cobwebs and live spiders crawling around.
After a few seconds of mild surprise, the two started giggling. This was far from the first time it had happened, to the point where the kids and parents nearby were only somewhat shocked by all this.
"Well." said Muffet, taking a drag on her cigar. "It seems I must have been hungrier than I thought. Want to be let out? Give one poke for yes."
Frisk poked the inside of Muffet's stomach and grinned.
"Sure thing, sweetie." said Muffet, blowing a few smoke rings that hung in the air above her. She then puckered her lips and spat Frisk out like a cannon.
Frisk soared through the smoke rings as they shot into the sky like a human cannonball. They soared even higher this time, again confusing some nearby birds. As they reached the height of their flight, Frisk did some somersaults in the air as they fell back towards the ground before using both feet to stomp down on the other end of the see saw just as they landed.
This caused the see saw to spring up with an even louder "SPROING!" launching Muffet far off into the sky, causing the children and parents nearby to look on in amazement. Frisk raised a hand to shade their eyes as they watched Muffet shoot off into the sky until she was only a speck, where she disappeared with a bright twinkle that made a high pitched ringing noise.
When the twinkle disappeared, the nearby kids and even some of the parents cheered in amazement at Frisk, who smiled warmly.
