Summary
I like the head cannon of Sans having raised Papyrus. I also like the head cannon that all other skeletons died when the Barrier went up. So we all know PTA Sans, the punning and protective skeleton who join the PTA for Frisk. The thing is, in what I've seen, he acts experienced.So I like to think that he did the PTA before, for Papyrus. He had to make skeleton needs and growth and customs known to monsters who had never even seen a skeleton before. And we know how much Sans loves his brother, so he was probably very dedicated. Maybe he transferred some of that dedication to the human PTA.

Yellowjester fic (ft other ships) by Th3_b3st_C4k3
Fandoms: A Fallen Kingdom, Roblox Myth, Roblox
24 Jul 2025
Tags
Summary
This is from a small but amazing Roblox arg myth called A Fallen Kingdom that is currently still ongoing! Please go check it out, owner of the myth is ANGU1SH3DC0SM1C (cxs_m1c)! Most of the stuff in here is either based off actual events or one of the character's actual in game fanfic.
Kunimitsu is your everyday angel trying to blend in with the rest of humanity by getting a job, as a myth hunter! She goes everywhere, risking her life for barely enough for rent. She goes on more and more dangerous missions and investigations to try and get paid more, and finds herself being assigned to a very meek and introverted looking jester instead. Why was his myth written as so extremely dangerous? Either way, she put on her best smile and got to work. The moment she walked into that diner, her fate was irrevocably tied to his story.

Tears in my eyes, i guess nothing’s guaranteed by Anonymous
Fandoms: Undertale (Video Game)

Summary
It was a miracle the Stars managed to stay so close. One would assume they would grow apart eventually, with Dream’s responsibilities piling up enough to rival a queen’s duties, Blue disappearing every time school lets out for over a week (alongside his ongoing and increasingly stressful competition with Cross), and the two only catching even a glance Ink three times a day in the hall. Even when they caught a moment of peace, the three (diligent as always), would spend it on rehearsing their songs.
But once in a blue moon, after their work was finished and music practiced to perfection, the Stars would finally have time to act like regular friends.
That’s where they found themselves now— lying awake during a sleepover in Ink’s dimly-lit bedroom in the middle of the night.Title from Summer in Chicago by Pinksqueeze

To Mend A Shattered SOUL (previously Shattered SOULs) by Thunder_child
Fandoms: Undertale (Video Game)
24 Jul 2025
Tags
Summary
How many times will my body be burned? How many times will my bones be broken? How many times will my blood be spilt? How many times will you shatter my soul?
Frisk has been through the Underground countless times, pacifist run after pacifist run, yet she cannot escape. Every run, she confronts the monsters, offers mercy, dodges, tries not to die, and inevitably is killed by people she has called “friend”. How many times will her soul shatter before she decides enough is enough?
Sans has watched Frisk’s journey through the Underground countless times. Each time, she chooses mercy. He’s proud of her. It’s a little boring watching an immortal run around trying to do the impossible, but hey, not like anything bad will happen.
(Yeah, you thought this work was finished! Ha, joke’s on you! Or me, I guess. I also thought it was finished. Well, it dug its claws into me and won’t let go. Blame Toby Fox.)

Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

Dream was a normal teenage girl moving into the big city with her twin sister Nightmare. Nightmare had a terrible habit of attracting bullied in the small town they used to live in, so hopefully this will be a fresh start for both girls! But before Dream could even start the year in her new school she becomes a magical girl! 😱
Now it's her job to defend the city along side her new friends Ink and Blueberry! But something dark lurks closer to Dream and her sister.
Will Chaos prevail? Or can Hope stay strong even at the darkest hour!?Find out next episode! Cuz god knows 24 minutes isn't long enough for any progress to be made with how long these fucking magical girl transformations are!
