    Summary

    You are dreaming... right? It’s gotta be. Sure the monsters look realistic as heck and the whole plot is in order but that’s dream stuff, a pipe dream. You’re an avid Undertale fan, so having this opportunity in the first place, you might as well enjoy it until you wake up... if it is actually a dream. And you’re sure hoping it’s not!

    THIS IS A CASUAL REALITY MEET UNDERTALE STORY.

    ("How often do you update?" Yes. [the real answer is approximately 1 - 3 days])
    ("Do you take criticism?" Yes, as long as it is reasonable. I might not be able to change the whole plotline, but grammar and such are greatly appreciated!)
    ("Is reader a girl or boy?" Your choice! The pronouns should all be gender-neutral. If you see a typo, please comment on it. I read and treasure every single goddamn comment you guys post and it always makes me smile!)

    Summary

    What is the relationship between Fresh the parasite and Fresh the host? Just how well do they get along? What better way to find out than a game of Truth or Dare with people who don't know how to not ask personal questions?

    Summary

    You're a struggling college student who's gradually getting their life in order. That all changes when you're thrown into an alternate universe with a familiar group of skeletons, had it'd been your horny barely-legal teenage dumbass here instead of present-you, your teenage self would've been jumping for joy- but now?

    You just hope they can handle the storm that's coming their way, in a form of a very fed up adult human who's struggling to deal with all their shenanigans.

    Until they get that machine fixed, you're living with some pretty dangerous monsters. But with a borderline death wish you can only hope for some sort of relief, which un(lucky) for turns into some much-needed love for you and the skeletons.

    Summary

    Alphys has achieved her dream of becoming the Royal Scientist- so what if she had to tell a slight lie to get here? Now she just has to... figure out how to make an entire soul. No pressure. It's just monsterkind's dreams of freedom on the line, after all.

    Summary

    Living on a homestead was nice. You provided for yourself through hard work, and didn't rely on anybody else. Then your deer gets caught in a trap you didn't set. The neighbors kind of freak you out, but at least Papyrus is a great cook. Also why does Sans stare at you all the time?

    Summary

    If you ever wanted to know how many junk drabbles I had kicking around behind the scenes until about a year or two ago, this right here is a perfect little package of all the WIPs that had enough substance to them to be considered stories. I might not have drawn a whole lot for certain things and I really didn't share how involved I was in some of these fandoms, but boy did I write a bunch of garbage that would come back to haunt me.
    Enjoy the torture that was my idea of a good plot in junior high and high school, updated every Saturday~

    Summary

    You didn't know what eating those people could do to you. You didn't know how falling into the underground would change you. You can't bring yourself to regret it, either way.

     

    Or, I wanted to read a fic where; Sans and Reader were already in a relationship with none of that waffling back and forth nonsense, surface monsters exist and reader is one of them, Horrortale Sans and Papyrus healing, and Reader becoming a Wendigo via eating humans and exposure to magic. This sort of popped into existence.

    Summary

    You’ve dealt with a lot of rejection in your life. No matter how many times it happens, the sting still hurts. It’s the worst experience in the world.

    Or so you thought.

    But what if it turns out the opposite, having someone try to express his endearment toward you, ends up being the most unsafe, twisted, and damaging thing to your soul and your sanity?

    Summary

    Dream and Cross are total opposites. Dream being the quiet, friendly, semi-nerdish type, and Cross being the total weeaboo introvert. Most of the other freshmen, including themselves, think that they could never get along. So when their English teacher pairs the both of them up for a group project, you can only imagine their reactions.

    But they do have things in common. And one of their secrets might just bring them closer together.

    Summary

    (Inspired by Writers_War_Zone’s The Soldier and The Carnal Skeletons)
    This vacation was not what Y/N had expected. She just wanted to get away for a week or two on a cruise when she had enough money. She was not expecting to get shipwrecked on an unknown island with 4 very horny skeletons.

    Summary

    Pressing yourself up against the wall furthest away from the door of the carrier, you listened. Silent, was the first thing that came to mind. Isolated, the second. Then you heard the wind whipping through the branches of the trees, the distant calls of birds singing for mates, Ms. Diana knocking on the door, and a river somewhere far in the back.
    The air itself was cool, filled with a million different scents that you couldn’t wait to stalk. There were small animals, squirrels, birds, mice, you could even smell moles. It had been a long time since you last saw one of those velvet soft pests.
    For a moment, all you could taste was freedom. And it was addictive.

    Summary

    Ah, an office. A paper supply office. You'd think working there would be boring, quiet, but it isn't exactly like that. With two branches who hate each other merging into one, and a power obsessed person placed in second command, things will definitely get interesting in the Eastern branch. Drama will ensue, romance will blossom, and much more will happen in this office.

    While the skeletons have to sell paper stacks.

    Summary

    Royal Scientist, husband, and father W. D. Gaster fell into his own creation, destroyed and erased from existence. Even with the barrier broken, he could never return.
    Or could he?
    The Font brothers and Grillby are experiencing strange phenomena in their homes. What could be the cause?

    Updates every other Sunday (optimistically)

     

    EDIT: this fic is NOT, in ANY way, affiliated with that one anime with the ridiculous dub. You know the one.

    Summary

    Dark, yet Darker.
    In spite of the invitation the Darkners and the entire kingdom received to join the above ground world, there are still a few left behind within the otherworldly caverns, lost, hopeless, or in Jevil's case, still locked up. Charlie, a representative for the rights and acts of monsters and the like, must find those who are left behind and bring to the light. Even if it breaks her.

    Warning: Spoilers! Lots of 'em.

    Please bear in mind this is a possible universe/AU/ending that I'm sure won't be canon due to the game being a demo. This will be eventual NSFW; no xReader for this storyline, maybe in the future if it is wanted. However, there are other humans here, too.

    Summary

    I wanted a Fresh/Reader story.
    Because yes to the energy Fresh gives to life.
    So I made one.
    But with Canon Fresh, loveresofpiggies assigned, personality because it's the best personality really.
    And also because the only other personality I've met was the paper jam one.
    And I don't like that one.
    It's like, the most classic standoffish but cool and approachable seme personality in a yaoi.

    This is the baby of all those criteria met.

    Summary

    Due to an accident Blue and Error are sharing a body, and they know no one will believe who they are. Now what is the cinnamon bun of the universe and the god of Destruction do now that they can't go home and no one recognizes them. Well.. Bluescreen always did like pranking and Trolling.

    Summary

    You had recently moved to the town near Mt. Ebott but you didn't believe in the legend that had everyone scared. One day when you were climbing the mountain out of curiosity you had discovered a hole where you guessed that the seven previous humans had used to commit suicide. You were about to leave when a voice called for your help. You had reluctantly answered it and wound up falling into the hole where a flower and a child were having a conversation.

    This is where your journey to save the poor souls of every monster and a human trapped between life and death begins.
