    Summary

    It’s been forty years since monsters came to the Surface, and five years since you moved across the country to live on the west coast. You were born with magic sensitivity, like thousands of other humans since the destruction of the Barrier, and the closer you move to the source of magic the happier you feel. It helps that one of the best law schools in the country isn’t far away. To make ends meet while in school, you work for your cousin in his tattoo parlor that employs humans and a very handy monster.

    An unknown, and dashing, skeleton monster walks through the doors one winter with unknown intentions. Now, he’s asked you on a date, you’ve met Frisk (the Frisk! Crazy!), and you’re the happiest you’ve been in years. Who would have thought this holiday season would give you such a gift?

    But be careful, because even on Christmas, things can be too good to be true…

    Summary

    This will be a collection of requests taken from Tumblr, and the comments on this piece of work. All those who go through my Tumblr (which is right here for anybody wondering) will have their requests done first. I'll be doing these completely for free and for fun, so my only request is that you don't overwhelm me, and if I do not wish to do the request for my own reasons, please accept that.

    Requests are currently closed
    Current number of requests is 4

    The cap for requests I am presently working on is 5.

    Summary

    You had to hand it to the plant. Although you didn’t trust him, you definitely didn’t trust the ragged goat lady even more and once you mentioned him as he suggested, she left you in her house alone, when you promised to go to sleep in the kid-sized bed you barely fit into. Once you were sure she left, you took a chance on the directions the flower, Flowey, gave you. And now you were here, trying to make sure the dead stayed dead because hell had apparently frozen over.

    Summary

    Sex.
    In human culture, it is both vilified as well as romanticized. Young people are both discouraged and encouraged to have it, and especially in a college party atmosphere, the mixed signals can be stressful.
    Then the monsters came to the surface, and from the other universes. It was never fully explained why or how, but it happened, and they were quick to stick together. Within months, Undertail University was founded by Dr. W. D. Gaster, and it gained a reputation as a thriving college atmosphere that boasted high graduation and success rates. It also boasted a very different view of sex, one that monsters had been entertaining for centuries.
    Somehow, against all odds and despite what people said, you’d applied.
    Somehow, you’d been accepted.
    And somehow, for some unknown reason...you’d enrolled.
    (Based on the headcanons of Skelltales and the #discordcrew on Tumblr, as well as some of my own. Written with permission.)
