    Summary

    It's not that Y/N had a bad life, just one that wasn't very fun or fulfilling. When you meet Papyrus and Blue, everything changes. When you learn your twin sister, Edwina, met them, you fear you've lost their friendship as you had so many that Edwina wooed away. But, to your surprise, Papyrus and Blue were just the begining. Through a series of events not of your control, you find yourself even more intigrated into the lives of several skeletons. Some don't like you and some do, but that's life.

    And your life will never be the same.

    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    It is rather peaceful to be in Paperjam's daycare. There are lovely things that happen for all of the kids. There are things to do, and they are all allowed a large amount of freedom. However, there could always be the chance for danger. Paperjam learns this the hard way when one of the very children he is looking after starts to show minor signs of depressions and major amounts of sadness. Worst off, he is not willing to talk to Paperjam to get this all sorted out.

    Adding on top of the pile, there is a kidnapper on the loose and he is hanging closer to PJ's daycare than anyone realizes. Now all of the little Sans's and Paperjam are trying to re-open the closed book Sans and bring him out of his shell, not realizing they are the very ones that had put him into it.

    Can they do it? What will become him if he is abducted by the kidnappers?

    Summary

    Error and Lust could never get along but of course not. They're total opposites; a haephiaphobic glitch and the whore. They're fights were getting on everyone's nerves so some punishment was in order or at least that was what the Sanses were going for. Instead it failed epically and a new out Come was the result. Akarun was born, the fusion between Error and Lust. The Sanses now rush to find a way to separate them but maybe being fused isn't so much of a bad thing. They can finally learn about eachother and maybe get along.

    Summary

    Fresh passes you by on the street.

    Like a bug underneath his boot (heelys), he doesn't take notice of you.

    Not until he notices all of the Skelebros' and their interactions with you.

    'Feeling' a little left out, maybe he should do like everybody else and say hello?

    Summary

    Undertale AU Garbage. LOVE, love, smut, angst, edginess, and self reflection. A story about teamwork and friendship, with lots of puns, ships, and feels. Full of head-canons what might deviate from the original story and/or AU ideas.

    Worlds collide when shortcuts resonate. Will they be able to find their way home?

You struggle to keep your jobs, your powers, and your heart under control, but shenanigans ensue. Because you're dealing with skeletons.
