A/n: This story is from the good old-fashioned brain membrane (yes it's a thing, just a more complicated thing)! I hope you enjoy how this story plays out and feel free to comment on your concerns if you do not! Thanks for reading and I hope ya enjoy!

I hummed a bit to myself as I slowly and methodically climbed the side of the rocky incline, using the handholds someone made most likely years ago. I was told by a mysteriously small child that a pool of healing liquids was at the top of a mountain surrounded by traps. At first I thought she was joking around to try and mess with me, but so far the map had been correct, even when it came to mythological obstacles. I've had to fight a huge wolf, get directions from the ghost of a root beer detective, and trick a robot into getting stuck on a living piece of jelly before kicking it over another, smaller cliff. To be short, today has been a very weird day.

(Y/n)'s Mind: And it's not even breakfast yet. I'll need a long nap after this.

I sighed and continued to climb up onto the cliff before I immediately got to the top of a cliff, only to find a small lake surrounding a small patch of land with a fancy and ornate-looking cup filled with the liquid in the center of it.

(Y/n): All this hassle for a silly chalice? What a letdown.

I backed up a bit to the edge and took a large running jump, just barely landing on the edge of the small piece of ground in the center of the pure and mint green pond. Quickly steadying myself and making my way towards the sophisticated-looking container before what looked like a furry paw stretched out and snatched away before my hands could grasp it.

(Y/n): What the-?!

???: Sorry honey~! We need this a lot more than you do!

Quickly unsheathing my sword, I turned to the origin of the voice with the intention of taking back my prize before being met with a girl around my age sitting on top of a gigantic and stretchy cat.

(Y/n)'s Mind: Well that's something you don't see every day.

???: Hey there! Sorry about that, but we were told to come here and we can't just let you take this! This is the best one!

(Y/n): Who are you?!

???: I don't see why we should-

Fionna: My name is Fionna, and this is my cat and best friend, Cake!

Cake: Fionna!!

Fionna: What? He seems like a nice guy! Plus he is the guy from the picture!

(Y/n)'s Mind: She has a picture of me? Well that's not creepy at all...

Contemplating the situation, I considered simply grabbing any of the surrounding liquids, considering that they said that the chalice was the best one, and not the only one. Anything was better than sticking around here and seeing what they were going to do.

(Y/n): So it's nice to meet you, but I really must be going so I can deliver this. So see y-

Fionna: I don't think so! Cake don't let him get away!

Cake: Alright, if you're sure, then I'll trust you!

(Y/n): Crap!!

I bolted towards the edge and jumped off, taking out one of my ice axes that I had taken in preparation for an upcoming snow expedition and slamming it into the rock with all my strength, slowing my fall but causing a sharp and painful sensation to enter my arm. I bit back the urge to scream as I unhooked the other axe from my belt and quickly swung it at the rock, causing it to get implanted alongside the other one.
