Hey guys! I've decided to make this a Jeff the Killer x OC story instead of Masky x OC because the way I wrote the next chapters, it just seemed better with Jeff. Ok, thanks, enjoy!

I paced back and forth impatiently as I waited for my friend. She was helping me bust out. As I was waiting, a thought hit me.

Where would we go? This lab has been our home for as long as we could remember. Maybe, just maybe, we could become hobos. No… where did that even come from? My hobo thoughts were interrupted when my ears perked up as I heard footsteps.

"Okay, it's midnight," I heard Magenta whisper. Her keys jingled as she struggled to find the right one.

"Here, let me," I said quietly. I reached out my hand in between the bars of my cell, and Magenta gave me the keys. Thanks to being part feline, I could see pretty well in the dark. Within seconds, I found the right one.

"Earlier," I said suddenly, "I was thinking. Where would we go?"

"I don't know," she said quietly. "Did you come up with any ideas?"

"Hobos!" I blurted out. She gave me that one looks that said, "Really? You need help."

"What, it was the best I could come up with! Now get me out of this stupid cage!" I snapped.

Magenta sighed in annoyance as she unlocked my cage, but as she did, a loud alarm sounded, making us both jump and my tail puff up.

"Run!" She shouted as scientists raced toward us. We ran as fast as our legs could carry us. I was a bit faster than her, so I actually had to drag her along. We made outside, but we didn't stop until we were deep in the middle of the woods.

"Oh, great," she panted. "Now, we're lost."

"Would you rather have been caught?" I retorted, "Besides, why are you tired, I did all the running."

"It's kinda hard to not fall on your face while you're being dragged along by a super-fast cat girl!" She rolled her eyes.

"I'm not a-"I was cut off when I felt a sharp pain on the back of my head and I fell to the ground.

"Sky!" Magenta shrieked, and then she slumped down and fell unconscious. After that, my vision faded to black.

I don't know how long I was out, but I woke up in what looked like a… bedroom. Oh, my… never mind, I'm fully clothed. I sighed in relief as I just remembered…

"MAGENTAA!" I screamed as loud as I could.

"Really, Sky? I'm right here."

"Oops."

Suddenly, I heard door creak open, and I quickly turned my head to the source of the noise. I saw two boys standing in the doorway.

One had a yellow hoodie and a mask with red eyes and a stitched frown, and out of the corner of my eye, I could see Magenta making googly eyes at him. The other was wearing and orange jacket and a black and white mask and slightly messy brown hair. He was kind of attractive, I guess. There was an awkward silence, before I decided to break it.

"Hi," I said.

The one in the white mask finally composed himself. "Hello," he started. "I'm Masky and this is Hoodie. I-" he was cut off when another boy burst into the room.

"W-what'd I-oof!" he stopped when he tripped over his own two feet and face planted on the floor.

"And, this is Toby," Masky said with an annoyed tone.

Toby was wearing a striped brown hoody and had orange goggles and a mouthguard and messy brown hair. Hmm, these three looked familiar.

"As, I was saying before I was interrupted," Masky "glared" at Toby, "Welcome to the Slender Mansion, as you'll be staying here for the rest of your lives."

Hold up, hold up. Slender what now?
