Summary
What were to happen if you killed one brother rather than the other?
(Two-shot where Papyrus likens to murder and bloodshed yay)

Did you know, on the surface, there’s an animal called a mole that digs through the dirt? Did you know that makes noise? Not the digging underground, but when they break to the surface, you hear these light tapping noises, something crackling, which is the sound of the grass breaking.
Now, despite the similarities, when Flowey pops up, you do not necessarily hear this sound. Sure, if you listen, you might be able to, but what you hear first is a screeching , incessant voice, saying—

Summary
The radio sitting unused in the corner of the basement, placed there by Papyrus who knows how long ago in hopes he wouldn't just sit in silence down here all the time, stops his spiral in its tracks.
Mostly, it does that by suddenly turning itself on.

Spending Spring Break Underground by 4Trixs_Animations3

Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
Sans isn't looking after himself anymore.
He barely gets out of bed, barely showers, and barely eats.
Papyrus is making it big out there, and Toriel has the potential of becoming a teacher within her grasp.
Left alone to assume the role of Frisk's deadbeat uncle while everyone else achieves their hopes and dreams, he feels like he's been handed the short end of the stick.
Frisk decides the best way to help Sans is by shoving him into a series of awkward encounters with their single mother.
So, when Sans notices they're playing matchmaker to try dragging him out of his destructive cycle, he tries to stop it, though it's too late.
He already has a cute lady wanting to jump his bones and rattle him up, and all it took was making himself look decent for a date to McDonald's and Baskin-Robbins.

Under the Water Oak Tree by BubblyShip

Summary
Alasor had this tree in his room. Native to New Orleans, with thick narrow leaves that cascaded up into the dome of a ceiling. Just past that, the architecture was anything but quaint- with fire flies buzzing about the air of green and blue foliage. Somewhere, somehow, the sound of nature always chirped from that centerpiece tree.
Sans would have found the tree appealing. If he wasn’t trapped with it.
-or-
Alastor weaseled his way to some fanciful contracts when a sudden influx of monsters in hells population occurred. One of those unlucky souls was a certain skeleton Alastor took a very intense, platonic liking to.
Sans is thoroughly not amused.

Summary
There was no hope.
There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.
No more resets, after all.

Summary
sans is fifteen, an up-and-coming boss monster, and widely considered one of the smartest kids in his generation. He gets good grades in his classes, when he bothers to show up. He helps his dad in the lab, triple checking equations, writing up simple code and sometimes even helping his dad and the engineering team overhaul huge sections of the barely-functioning brand new CORE. And on busy nights he worked the dish-pit at Grillin's restaurant for pocket change. But he's also a teenager, and as smart at teens may think they are, they're still prone to making decisions that they aren't ready to handle.
One night sans discovers something that will change his life forever, he doesn't have the strength to tell his dad about it and instead shoulders the burden himself.
How will sans deal with the consequences of his actions? How will his friends and family react when they inevitably find out? And most importantly, what is he going to do with a tiny baby skeleton?
