    Summary

    Monsters from different AUs are coming to the surface one at a time. The Tales open their home to the Swaps when they come until they can get on their feet. When the Horrors arrive, some time later, the Swaps decide to take them in just as the Tales did for the Swaps but things don't go as planned for them (both in good ways and bad).

    Sans ends up offering to help even as he is slowly falling.

    Summary

    Frisk es una princesa amable y manipuladora que deseaba solo una velada divertida en Giftmas, gastándole bromas a su fiel guardia real Sans quien estaba dispuesto a dar hasta su propia cabeza si así ella lo quisiera. Pero las cosas terminan torciéndose para los dos.

    Un corto de un au en desarrollo para conocer una de las festividades del universo alternativo de Swapfell, ambientado en una época seudo (falso) medieval. Donde Frisk no aprecia a los humanos pero si a los monstruos y su cultura, mientras que los monstruos no desean ser liberados ni expuestos.

    Summary

    Plot device is convenient, and the Human always causes mischief. Thanks to said mischief, the skeletons are introduced to entirely new world, one that is both adorable and disturbing all at once.

    Bitties may be simliar to other verisons of Bitties but they are not all exactly the same.

    A continuation of Light Drizzles introducing the Bitty Universe, turning out to be so massive it needed it’s own separate story dedicated to it. It is recommended you read Light Drizzles before reading this, but of course you don’t have to. There are some context stuff and events from the first story that are referenced to here.

    Featuring lots of Bitty artwork in most of the chapters!

    Master Name Key at the Bottom!

    Summary

    Extra chapters for one of my other works Xtra Small, containing some bonus canon chapters, what-if scenarios and other ideas that just had to be included.

    See what mischief a young Cross gets up to in Nightmare’s hideout and out and about in the multiverse!

    Pets, dolls, movies, blanket forts, cuddles, cute family times and much more to be seen in these extra bonus chapters!

    Rated Mature (just in case) for some darker chapters (only one or two of those right now), but most will be General for all readers. Warnings will be placed in the beginning notes for those particular chapters.

    Requests for chapters welcome!

    Summary

    You pass away abruptly, and you manage to lose everything.
    Then you're thrusted into another body, into another life.
    You become Sans, yet something is wrong. It isn't fun, thrilling nor what you dreamed of. It is war torn, violent, unforgiving and everything goes wrong. Papyrus hates you.

    Then from war you end up in a basement face to face with better alternates. Your memory is hazy and LV high, how will you deal with papyrus ignoring you, and the weight of your sins? How will you control yourself?
    You won't be able to hide from your alternates for long, and they're strangely pushy. Life seems to hate you, doesn't it?

    -
    Chapter 1-3 is back story, and importante to the main character(sans/reader)
    Main story starts on chapter 4.
    I suck and I honestly have problems writing a cohesive story, plz forgive

    Summary

    I bring you the area where I will put everything that is short and mini-chapters.

    Different topics that I like but i don't have the time to create a long fic…
    I will try more different topics here and even i will try to make new ones.

    I will add a lot of names from other authors here since my mainly idea is to help other people find ideas and create their own stuff.

    This area is for one shots, I think people calls them like that?
    Unrelated stories that have only 1 chapter or 2 if i make a pov from Sans.

    And also i will add the first chapter of long stories here to make you feel the boom of a new story beginning.

    That way you'll never miss one of my new fics and you will learn from yourself if you like the story or not.

    I accept ideas and suggestion. (Inside my possibilities and own likes)

    A book of one-shots dedicated to @kioko-doodles' mermaid pirate AU! Harp is the only character that belongs to me. All other characters belong to their respective creators on Tumblr.

    This will be based primarily around Harp, but I might try writing in other characters later.
