Summary
...“just adding two and two—i’m a scientist, and you are dumpster diving. i think we could help each other.”
The skeleton just continued to stare, warily locked onto his lab coat instead of him as they stepped back.
...“just… give it a day or two?”You never knew what you might find in the dump. But out of everything he'd brought home for a project, Sci never expected a young homeless creature to be one of them.
Problem is, feral kids don't make for easy science experiments. Now Sci's stuck with Ink: a small, strange skeleton with a past neither of them know and a future they know even less.
It's going to be hard keeping them safe in their quest to fit their multiverse. -

Summary
With the magical healing powers of ketchup, Sans survives a genocide run--but the rest of his world doesn't. He sets out across the multiverse searching for a family he refuses to believe is dead, struggling to come to terms with his new life and identity and making more deadly enemies the further he goes. When a rival emerges, he's forced to choose between his past and future or risk losing both.
Complete
(Yes, this is absolute crack--but I found out there was no AU where Sans's soul is literally ketchup and decided that was a problem I had to solve. There will be family fluff, plenty of angst, a bunch of AUs, and general shenanigans. I'm treating this seriously enough that I forgot how ridiculous this was until I had to write this summary.)

Summary
'How do I always get myself into these things?' you thought while standing in front of the King of Negativity. It seemed that had been your luck for the past few years. You clutched the necklace around your neck for support because, in all honesty, you weren't sure what you were getting yourself into.
A reader-insert of my other work with the same name.

Summary
An undertale au of parents and children. It all began with Ink and Error, creating Pj in the heat of the battlefield. Baffled and annoyed, Ink forced Error to take care of Pj, and they split the time their child spends time with each. But it doesn't go well.
In the meantime, Ink and Error aren't the only ones who get children. One's are accidental,others are purposely made in agreement. How will it go?
This story is a collab between me and my wonderful friend Ceask (they don't have ao3, so I'm posting it here for both of us)
