    Summary

    A year and four months. That's how long it's been since the Final Reset. Everyone has been living their best lives on the Surface. Sans, for one, couldn't be happier. The silly old woman he used to pun with is now his girlfriend. He's an awesome Dunkle and Not Dad Guy to Frisk, Chara and Asriel. Papyrus is finally living his best life and everyone is moving forward.

    There's just one little caveat. One teensy little flaw in an otherwise happy ending.

    Sans is dying. On the evening of his 27th birthday, no less.

    Fortunately, a certain skeleton outside of space and time knows what to do.

    "If you want to save Sans, all of you must be willing to pay the mental and emotional cost."

    In order to bring Sans back to life, those closest to him will have to view his important memories. Along the way, the group will unearth all the skeletons in his closet...

     

    ...As well as their own.

    Summary

    A mineral meet-cute leads you down a rabbit hole of friendship with a certain lazy skeleton.

    You're a geology major at Ebbot Tech, so so close to getting your Bachelors degree. Working as a TA in the department, you lend your printer to a slipper-clad skeleton. Gods, why is he so funny?

    Get your head on straight! You can't afford a distraction! You're so close to graduating!..

    But Sans is so sweet. It'd be a shame not to give him your number...

    Summary

    There was once a story about the Judge. A tale about a powerful monster who decided the fate of all who’s soul was dark and evil. Some monsters, would never be seen again… And some monsters, would leave unharmed. The identity of the Judge was unknown. The only ones who would ever see their face was those who were judged, and the King.

    It was a tale told to children who’d make trouble. Usually to scare them out of bullying or harassing others.

    But the Judge was no fairytale. He was a real monster.

    His name was Sans, and he had never wanted this…

    The king was a fake. An abuser, a psychopath.

     

    Now, on the surface Sans lives with his makeshift family. All is well, and everyone looks out for eachother…

    But what happens when the king stops waiting to get what he wants, and uses the Judge after years?… And what happens when Sans’ family doesn’t stand for Asgore’s abuse against the young skeleton?…

    Summary

    Frisk knew they shouldn’t be doing these things. They’re only 15! But they couldn’t help it. And besides, their family won’t know about it. So what’s the harm?

    Aka I didn’t like how nobody wrote about how Frisk was literally hunted down when they were like, 7 and how it may have affected them. So I decided to do it.

Old traumas die hard, it seems. Just a short and sweet one-shot about a very classic concept for the Undertale Fanbase.

    EDIT: 1/26/2016
    Initially, this was going to be a bunch of one-shots. Somewhere along the line, it's evolved into something more. If you like ridiculous amounts of fluff, subplots, generous helpings of character development, and some fantastic jokes, click that title and enjoy the ride!

    Summary

    You work at a child's dream- a shop full of pastries and chocolates of wide varieties. The one thing that get's your blood boiling? Monster discrimination, so you end up intervening with a near-violent monster-hater. The skeleton himself seems appreciative of the intervention, and you thought that would be the last time you saw him. A couple days later your bestie- Alphys- invites you to a party. She asks you to bring several assortments of deserts from your workplace, all paid by her of course. When you arrived a familiar face lingered in the side of your vision. What's he doing here, and why is he looking at you like that?

    Summary

    You're a green-thumbed gardener who works, and lives, at the old library in town. You're the sole guardian of your two little twin siblings, and they're constantly making sure to keep you on your toes, as well as also constantly making sure to keep your dang sappy heart full to bursting.

    After a bit of time, and with the help of your little siblings, you befriend a local skeleton monster or two. Or three. Make that four. Hup, turns out there's a lot of 'em in town! And they all live under one roof; an old hotel that's less of a hotel now than it is a giant private apartment building for said skeleton family.

    Monsters have been up on the surface for a good while now, so you're always looking on the more positive, brighter side of things, hoping that all that hatred and vitriol that was so prevalent when they first came to the surface had died down, hopefully for good. But humanity has a tendancy of letting hatred fester to a breaking point, and you and your little family end up being offered a much needed safe haven with the skeleton crew after your library--a place you'd been so damn proud of and felt so safe at--is threatened.

    Family isn't blood. It's trust, love, and maybe a little bit of magic.

    Summary

    They hadn’t even been on the surface two weeks when Frisk declared they wanted to take a road trip. They wouldn’t say why. They wouldn’t say where to exactly, either. Just that it was apparently quite far away from Mt. Ebott, and that there would be plenty of interesting sights along the way.

    “I know the way,” they said, and they sounded confident enough that their friends couldn’t help but believe them."
    ----------
    Written for doodleimprovement on tumblr as part of the 2016 Undertale Secret Santa. The prompt was: "family feels and Dunkle Sans." When Frisk proposes a road trip to show their new friends the sights on the surface, there's almost not enough room in Papyrus' new car to fit them all. Still, the surface proves to be a very interesting place. especially when you tour it with good friends by your side. And if Frisk has an ulterior motive for this roadtrip, well, it's not like the monsters don't owe the kid a few favors.

    When that ulterior motive involves a confrontation with the parents Frisk left behind to fall, Sans in particular is surprised to realize just how important this kid has come to be to them all.
