Disclaimer: I don't own Gravity Falls. If I did, there would be soooo many seasons out by now.

Shot of a party in the Shack with all the inhabitants and workers are in the shop with strobe lights and music. The cash register is replaced by a scratchboard operated by Midnight, the newest addition to the workers. Soos is dancing the best dance he could muster. Wendy is dancing pretty well with those party sunglasses. Mabel is dancing with Waddles and Dipper is nowhere to be seen. He then walks in supporting Stan, who is still blinded by the "rainbow incident".

"EDIT!"

The Midnight looks bored at the register, Wendy has a broom, Soos is placing things on shelves, Waddles is being Waddles, and Mabel has a checklist taking inventory.

"Huh, I thought I could hear those obnoxious sounds kids call 'music'. Eh, I'll go back outside and put earmuffs on for no apparent reason. Soos, you're in charge until I'm done." Stan then turns around and hits his head on the door frame, and then proceeds out the front door.

Dipper pokes his head in and gives a thumb up.

"EDIT!"

The music ensues and all the strobes start flashing once again.

"And that's it for Mabel's Guide to Partying Behind a Blind Grunkle's Back!"

Mabel's Guide to Life Theme…

Reading Fanfics (Shot of Dipper looking insane)

Nothing (Everyone is just sitting there doing nothing)

Eh, Out of Ideas (Mabel throwing a notebook in anger)

"Today's episode is Mabel's Guide to Handle People from Other Fandoms, with our special guest, Midnight!" Mabel points to the right of the room, the opposite direction of where Midnight comes from.

"Uh, Mabel, I'm over here."

"With our special guest, Midnight!" Mabel repeats, changing the direction of her finger.

"Thank you, thank you all." Midnight struts in and waves to the crowd (Dipper and some dolls, including Bear-O).

The scene changes to Mabel's bedroom, where a table and two chairs have been set up.

"So tell me, Midnight, what is it like to travel through fandoms?"

"Well, Mabel, imagine your looks changing everywhere you go? Looking in the mirror, just to find you look different. That is what shocks me the most."

"What have you looked like?"

"Ooh! I have pictures for you to look at!"

Midnight digs through his shoulder bag and pulls out an album that is titled "Fandom Changes". He opens it to show those instant pictures from those Polaroid© cameras.

"Well, this is from my time in the Harry Potter universe. Notice how the colors on me are dark, yet warm. That is sort of the type of clothing that happens to be worn there. And there is the cartoony animation of Invader Zim. I was surprised at how angular and small I was. Then there is the MLP universe. For some reason, I was gender-swapped into a girl Pegasus. My cutie mark was an eclipse. Then there's Phineas and Ferb. I was overly slender, like the picture shows. Of course, how could I miss out Adventure Time? The me there had a smooth and delicate frame. My eyes were, wait for it, dots, and my face seemed to be too wide. Talking about all this stuff, I need to take a picture in this fandom!"

Midnight pulls out the camera and starts taking a selfie with it. He is about to take the picture, but stops.

"You guys wanna join? First time for a character, or characters to join."

""YEAH!"" (2 quotations at once) said Dipper and Mabel.

They pose behind Midnight in awesome poses. The shutter goes off and the picture develops. Midnight looks at the photo and all colors drain from his face.

"Uh, Mabel, are you holding Bear-o at this moment or at any moment before this?"

"No, why?"

The kids and teen look closely onto the picture. Behind them is Bear-o, its smile more demonic than before. Everyone slowly turns around to find Bear-o floating and spinning. It stopped and stared at the three.

"Um, what to do now? Should we run from or face this monster?" Midnight asked getting tense with fear.

"Run, definitely run." Dipper skedaddled out of the room. Midnight and Mable ran out close behind.

Mabel picks up the camera and starts running down the stairs to the door.

"And this abruptly ends Mabel's Guide to Handle People from Other Fandoms!"
