    Summary

    Sans (Underfell) has plenty of time to consider how he got into this situation as he slowly sinks lower and lower in the ocean, his leaking mana leaving a trail of dirty red behind him as the light fades. He doesn't regret his choice to jump in and help defend his friends and baby brother, the last family he has left. He can't be angry at them, never could. But he can be angry at the stupid fish that tried to eat what's his to protect. So the last thought he has as his battered body settles into the cold, clumpy sand at the bottom of the ocean is simply: "i really hate orcas."

    Summary

    After a harrowing trip through Underfell, Frisk is nearly ready to go meet King Asgore. Their adoptive brother and good friend Sans would rather they go anywhere else—anywhere at all, as long as they don't get to that throne room. After all, in this world, it's kill or be killed.

    That's just this world, though. How about the next one over?

    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?!
