Summary
As night had settled over the Candy Kingdom, a crowd of chattering and whispering candy people had gathered around the bookshop, an unusual sight with it being so late.
They spoke of a monster. One with eyes made of glass, red frills on its neck and a face covered in blood. It had last been seen entering the building.
Finn thought he was ready for anything when he entered the shop, but the last thing he expected to come face to face with was an injured human.

I've actually already seen most of this story since around 2021 or 2022, but chapter 1 on this version is much different from the one I originally saw on DeviantArt, so I'm anticipating what further changes there might be for the rest. Did you know that this fanfic was started on early 2012? Yeah, it's very old! So excited to see this here and being new.
I'm preemptively adding this to my MordeTwi collection because I already know there's a MordeTwi moment happening in a much later chapter, and it's not what you think it is.

Summary
“By the way, I’m Finn the Human, and this is my brother Jake.”
Marceline froze.
“Finn… the Human?” she repeated.
No way, right? Of course she’d immediately noticed how human he looked, but a lot of creatures were shaped like humans nowadays. Every time Marceline got her hopes up, it ended up being for nothing.
An alteration of the events of S1E12 Evicted. When Marceline discovers that a human boy is living in her treehouse, she grapples with the idea that she and Simon aren't the only (part-)humans left in Ooo anymore.
