There's Something Hidden In Me (Don't Ask If We're Safe) by HailSam

Summary
Doctor Frisk is given a new job (after their last one nearly ended) of watching two skelemers. There has been an egg thief haunting about the place, and the two in question are expecting their very first-and, if things go wrong, potentially only-pup soon enough, making them a target for the thief.
Doctor Frisk will, of course, take this role very seriously.
They just have...a few other things they have to work through.
(A story primarily about Red and Blue and their baby, and kind of sort of about a human's dark secret they've carried with them for years.
But, well, you know, who cares about that! Baby mer time!!!)

Summary
Blue is a beautiful halo of light, a jellyfish-like mer whose soft underbelly belies his strength. Electricity and rage courses through his leylines, and a sharp beak hides under the beautiful, dress-like furling layers.
Red is a squat, slightly pudgy red-tailed mer, who is unable to tolerate much light. In the dark of the deep sea, his tail glows, spotted by a trail of glowing marks, with a bouncing light above his head mimicking a lantern fish.
They have been mated the moment they became of age, entwining fates that last them their entire lives.
This is but a collection of their tales, from the beautiful and lovely, to the gruesome and strange.
After all, they have a whole ocean to fill with their tiny pups, and all the time to do it in~
(AKA: Author made mers into a prompt fic. they gonna fuck. have lots of babies. we'll make it SO romantic I promise, just stick with me-)

Summary
...Though... well... it's just... Blue had spoken so highly of Red! He'd put in so much effort into that relationship, because he put effort into all his relationships. So it just felt embarrassing how abysmally wrong he was. Terrible judgement of character.

Or,
Blue is very happy with his relationship until he's not. But it's going to be okay. -

Summary
Error Sans had a very strict schedule. Destroy universes, gather information, visit Dream's castle, relax, attend the Nightmare Gang's meeting, and the cycle repeats. And repeats. And repeats. And repeats. But when his rival pops up during his moment of leisure, things began to change. Error is not prepared for any of this.

Summary
You have a Bitty. A cute little guy that you adopted almost 10 months ago. You adopted him and he has helped you with a lot of things. He made you feel better. Made you hopeful. Helped whenever he could. So when you get an eviction notice and you're forced to live in your car for an undetermined amount of time, you feel like giving up.
But your Bitty pushes you to stay determined. And so you do.
And who would have guessed that doing that would lead you to live with 8 bitties? Cause you sure didn't.
