WEIRD... (Gravity Falls but I add too many OCs)

Dipper²

Grey raised an eyebrow, but apparently, no one else thought his answer was suspicious, as Soos gave him a thumbs up. "Nice"

"The young people of this town want fun? I'll smother 'em with fun!" He said to himself, clenching his fist around the bags of confetti.

"Maybe comments like that are why kids don't come to the Mystery Shack," Dipper suggested, pouring Mabel a cup of diet Pitt.

"Hey, hey!" Stan grabbed the two-litre bottle from him, screwing on the cap. "How's about you make yourselves useful and copy these flyers?" He directed, handing Dipper a clipboard with a flyer. PARTY at the MYSTERY SHACK, Kids and Teenagers WELCOME. FREE?

"Ooh, boy, a trip to the copier store!" Mabel beamed.

"Calendars, mugs, t-shirts and more! They got it all at the copier store!" Soos chimed in with cheer, then seriousing up, "That's not their slogan, I just really feel that way about the copier store."

"Save the trouble! Y'know the old copier in my office? I finally fixed the old girl up! Good as new!" Stan beamed.

The twins and Grey then made their way to Stan's office, chatting about various things. When finally inside, Grey pulled the sheet off the copier to reveal that it was, in fact, not good as new. Duct tape barely held the thing together, dust coated every inch, and bugs scurried or flew away, and electricity crackled when the sheet was torn back.

Mabel gasped with a childish wonder, "Butterflies!"

Dipper opened it up, the lid screeched and spiderwebs were destroyed. "Does it even work?"

"Ten bucks something stupid happens," Grey said as Dipper pressed a button a few times.

He leaned his arm on the glass, looking at Grey, "I doubt this copier could even-" he stopped and looked at the glass as a green line of light scanned his arm. He pulled it back, turned around and stepped back, as did Mabel and Grey.

Electricity crackled, and a big cloud of black smoke puffed right into the three's faces. All of them coughed and waved their hands in front of their faces to ward off the smoke, which dissipated in time for them to see a paper with a black-and-white picture of Dipper's arm.

Mabel walked over and held it up. "Success!"

The paper rippled. Moved on its own. She yelped and dropped it, only for the arm to gain colour, reach out of the paper and to the three of them, who yelled in response.

The arm reached up, zombie-style, then pulled itself eerily towards them.

"Stay back!" Dipper yelled, splashing it with Mable's soda. The arm fizzed, bubbled, and disintegrated like it was cotton candy and/or Pop Rocks in water.

"Holy crap..." Grey said breathlessly, holding up their hand, awaiting payment.

"Grey, Mabel, I think this printer can COPY HUMAN BEINGS!"

A dramatic score played, and Mabel looked at Dipper.

"This changes everything I know about everything!"

...

"BLLAAAAAAAAAAAAAAAAAAAAARRGGGGHHHH!" Mabel sprayed Dipper and Grey with her can of purple silly string, which somehow evaded capture, while smiling ear-to-ear.

Grey meandered into the parlour with a plastic cup full of Diet Pitt. Everyone seemed to be lined up, so they followed suit absent-mindedly, focused on a piece of paper with things written on it. Dipper noticed them and tried to peek, but as soon as he did, Grey shoved the list in their pocket, just in time for Stan.
