A/N I know I should be working on my other story, but my friend gave me this cool story prompt, so I decided to do a one-shot on it. Enjoy!

Also Disney owns Gravity Falls by the way.

"Mabel! We have to keep moving!" My wounded sister could barely keep up as we ran down the corridors of the alien base. "I'm trying Dipper! *Huff* to keep up! *Puff*" Mabel was wearing a black sweater with a green alien head on it. We were covered in cuts and bruises, the result of trespassing on the alien's hideout, however, Mabel had a large cut to her right leg. I was able to make a tourniquet to stop it from bleeding, but it also hindered Mabel's ability to run.

"We're almost to the end, keep moving Mabel!" Mabel couldn't keep up, she fell over and hit the ground and was barely able to move. I turned around, "Mabel!" I ran over to my weak sister, put my arm around her, and lifted her up, supporting her while we moved as fast as we could.

Only a week ago lights were spotted over Gravity Falls. Without my journal I couldn't find anything about them. So my sister and I went to investigate, Mystery Twins Style. Eventually we came across a small alien outpost hidden deep within the Gravity Falls Forest. Of course being the Mystery Twins, we went inside.

Aliens captured us a few minutes after getting entering. They threw us a holding cell for hours. Later they opened the cell and forced us to move to an alien dissecting room.

They let go of us to ready the tables. That was our chance to do something. We fought back.

They are armed with alien laser weapons and dangerous tentacles that can grab anything that comes near. After we managed to take out the guards near us, the rest fired on and forced us to make a run for it. In the aftermath, we both took some cuts from being grazed by lasers, and bruises from being forced to hit the deck after being fired on. However, Mabel took a bad hit to the leg and was slowly bleeding to death. Luckily I was able to tear some of my vest and make a tourniquet to stop the bleeding.

But now we were running as fast as we could for the exit when suddenly it closes.

*Click* The door was locked closed. The green-goblin-like monsters stood in behind us, and the locked door was in front of us, we were cornered. "What will we do now Dipper?!" I could barely answer her or say anything but, "I don't know Mabel"

Their Tentacles surrounded us before everything went dark.

A/N I should be writing my other story, but I'm having problems with that, aka writer's block. So you can thank my friend for this story. Tell me how this story was. Also someone answer why I write better when I'm half awake at 10 at night!
