So you got woken up in the middle of the night by your new neighbors... no biggie! You're sure they're just excited to be in a new (cheap) apartment. So you decide to introduce yourself to them when they get settled in.
But to your surprise, your new neighbor just so happens to be a skeleton!
"Oh!" You say, surprised by your neighbor's appearance, "Uh hey! Welcome to the unit, I'm your neighbor"
"oh! hey i'm sans" He smiles, lazily copying your initial reaction.You hold your hand out to shake, he looks at your hand for a moment before accepting it.
when all of a sudden...
PPPPPPRRRT!
Was that a... whoopie cushion in his hand?

Summary
How long had it been since this all started?
Since the first Infected stumbled into the world, bringing chaos with it?
Felt like years. Years that could actually be mere months. Either way...felt too long. Too damn long.
Days blended together. Each one containing the same routine: wake up, sneak around, find food, eat when possible, check for bites, hide, search for medicine (just in case), be wary of fellow survivors, maybe bathe, find a place to sleep, check for scratches, make sure the coast was clear, sleep.
Rinse.
Repeat.

Summary
In which a little stop at Grillby’s with the skeleton brothers leads to a sudden tryst with the most revered monster Underground…
…now a big, lonely, fluffy figure hunched over, drinking his sorrows away. Well, you’re not the type to leave someone like that all by his lonesome. No, no, no. Besides, you’re always happy to lend a listening ear.

Summary
They say life is full of surprises, but [Name] never expected to end up in an entirely different universe, one filled with monsters, souls, and magic. But this isn’t some happy fairytale; it’s reality. And reality bites.
Adapting to this strange new universe feels impossible, especially when the skeletal monsters causing you trouble also happen to be your roommates. And 'passive-aggressive' doesn’t even begin to cover it. Still, no matter how lost or out of place you feel, you refuse to let go of hope.
After all, if life can surprise you once... who’s to say it won’t surprise you again?

Summary
It all started at the surface. It's a story told before, and a story that will be told again. But what if we went further back? To before the "Under" in Undertale?
This story takes place before cannon, and in the event that the war between humans and monsters was...delayed. This is mainly focused on the skelebros, but other characters will be mentioned. Please enjoy. Original characters are very minor

Summary
Hello!
This is a rewrite of a old fic I made(it still on this acc infact -w-), I don't know if I'm going to finish it in fact the text in this fic rn is like a month old sooo, uhh, I will try to but no promises lolOld description:
The Underground was a peaceful place, Until the king and Queen sons died. By humans, the underground went into anarchy, Until the Royal Scientist, Found the power within Lust. now a long, long time later a human fell into the underground.Notes:
So, uhh, I have dyslexic, and this is my first story, so sorry if the story come out slow. But hopefully I don't forget about this. And the main thing I should say this a full rewrite of underlust, because in my opinion at least the story not that good. So, I'm just going to try to rewrite it, to the best of my abilities, and this will be the shortest chapter, hopefully.(And I have not read other rewrites of underlust like Underlust NT, Underlust zirkkun, etc...)
