Summary
This takes place in a post Underfell King Papyrus ending.
Struck by under population, King Papyrus makes it law that all monsters left alive by the murderous little human have to procreate. This leaves Fell!Sans and The King himself in a tight spot. There are no female skeletons left in the whole Underground and both skeletons are sure they are the last of their species. Fell!Sans proposes something. With the help of the first Royal Scientist's machine to travel to other universes, he will find mates for breeding purposes.
Tale!Sans is having his first sub heat as a female. This happens when there are only males left and the strongest one undergoes a gender swap. He knows this means Papyrus will have to be his mate.
That won't do. They are brothers, for the Angel's sake! So he does what he does best, HE RUNS.

Summary
(Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?! -

Summary
Danny's time inside the portal was short, it was merely a moment, but he remembered the eternity of pain, pain, shocks rocking forst his body, then soul, then core. His death was fast, merciful even, from the logical point of view - he felt like he was still rotting,
Vlad was dying for months, his organs slowly withering, before his body succumbed to the stress of the illness, but he didn't remember any of it. A beam going straight through his brain, a supernova of pain, a distant shout, and the next thing he knew, Vlad was awake and healthier than ever.
No matter what, they both died. -

Summary
Mermaids are the social butterflies of the sea, living in sunny, shallow water together with the rest of their school. On the other end of the spectrum, meroctopuses are violent, antisocial fucks who like the cold and the dark, and who basically kill any competing predator they see.
But they aren’t stupid.
Red is proof of that, using his traps to hunt for food and saving his energy to ward off predators. So, how does he react when he finds the laziest creature in the ocean stealing his catch?
Bribe him with more food in exchange for peaceful company, of course! The ocean is fucking lonely for giant predatory mer!
Red unwittingly gets saved by those peaceful conversations. Apparently even a cold-hearted predator can fall in love. And from there, their family keeps growing as more lost souls are saved by the siren’s call that sings of peace, love, and family, no matter how terrible of a monster you were in the past.

Summary
Julia is an introverted woman in her 30s that attends her local college and for the most part, enjoys just barely cruising by unnoticed. But things change when she notices a certain monster and experiences feelings she's never had... For a real person. This person she has these feelings for just so happens to be Sans, a well-known popular skeleton monster who is always followed by his little "entourage" of fan-girls.
Always being the self-deprecating pessimist, Julia realizes she needs to just leave these newfound feelings unrequited and squash them down deep where they can never see the light of day and avoid Sans at all costs.Good! Problem solved.
...Or it would be, if she didn't drop her book that one day. She really should have not been so lazy about zipping up her backpack.

Summary
After getting fired from her job and kicked out of her apartment, Y/n ends up having nothing but a truck and her stuff. So, using what was left of her money, she bought a small, one bedroom trailer and filled it with groceries. And while looking for somewhere to stay that wasn't too far from the city, she stumbled upon an old campsite. Thinking nothing of it, she decided to park there and kinda just- live there, from now on. Now, here she was, friends with multiple skeletons who are all trying to get into her goddamn pants and going into heat left and right. Not to mention they all look incredibly similar, eerily so, and call themselves cousins. But Y/n isn't stupid, she knows there's something going on, and is determined to find out what. Of course, that's a problem for another time. Her current problem is figuring out to survive these damned heat cycles, and figuring out where the HELL all her clothes are. Especially her underwear, because she has a very limited amount... Wait, where'd her cat go?!
