In Gravity Falls- earlier that night... "Well, time to go out of town for awhile and see how brother Will is doing inside a reverse dimension!" Bill Cypher- the proud yellow triangle- bellowed. This dream demon merrily opened a portal. One HUGE portal above the Gravity Falls Night Sky.

"Goodbye for now old Gravity Falls! Remember: Reality is an illusion and the world is a hologram! Buy gold! BYE!" In a flash, Bill flew into the portal. But he forgot one huge old thing- actually closing the portal! At his absence, the huge portal continued expanding above Gravity Falls.

In the morning... Dipper Pines groaned in his sleep. "Dip! I need you to wake up- RIGHT NOW! It's an emergency!" He sighed as he rubbed his eyes and looked at his twin sister who's currently in mid-freeze after hitting him with the big puppy-shaped pillow. "What~? This better be important! It was tiring when we fought that monster yesterday, Mabel. I can't keep up with-" But his twin sister interrupted him.

Said Mabel dragged her brother to look outside their large triangular window. "LOOK!" She exclaimed as she pointed out a huge gaping hole above Gravity Falls. Dipper's child-like face was pressed against the glass. "Mabel! I can't- It would be easier to see whatever you're pointing at if you'll remove your hand behind my head. Quit pushing!" He told the still fazed girl. Once he had the clear view of the large number of screaming people and the portal, he yelped.

Dipper stumbled backwards with an 'Oof' and he gazed at his equally frightened twin. "What- WHAT IS THAT!?" He's trembling by now. The Pines boy picked his journal and at this state of panic- he still tried to look decent by wearing his vest and favorite cap with a blue pine tree symbol.

"I don't know! But it must've appeared while we're asleep! It's like a giant vacuum cleaner! It sucks things- people! I saw Soos get sucked in it! The sky must be eating us! I'm too young to be eaten by the sky!" Mabel wailed. "Time to wear my custom made panic sweater!" She added.

"Mabel! We have no time for this! We got to-" But Dipper's sentence got cut off by an oink. "Waddles! My pig!" Mabel yelled as she saw Waddles got carried of by the wind and up to the portal. "We have to stop this!" She exclaimed. "It sounds easier to say it than actually do it! My journal was not informed by any of this!" Dipper said as he skimmed.

"Then, do something! Anything! " Mabel yelled. "But, uncle Ford's journal have nothing on this! At this rate, our shack could get sucked in!" He told her and the two continued to panic. Dipper was more than ready to holler! But, they got interrupted by their gruncle Stanley- twin of gruncle Ford.

"Kids! What're you two crying on and on about? You need to get out! The Mystery Shack is getting-" the old man got cut off by a loud ripping sound of broken boards and nails from their tourist trap of a shack. "Everyone! Hold on!" the smarter great uncle Ford yelled as he followed suit.

They did as they were told and the Mystery Shack flew up with the strong winds and got sucked in the portal. So did everything else. After this, the town was no more. Not one got saved from the intense portal and the whole town was gone. Finally, the portal calmly drew itself to a close.

Everything was silent. As if screams weren't made earlier. The remains of the mystic town was none except the only reminder left standing. An untouched wooden sign saying that: 'Welcome to Gravity Falls, Oregon. Population: ???'.

Meanwhile, inside the world in the portal... "Hm. Nothing. I don't feel any different." Dipper said before standing up as he dusted his clothes. The old Mystery Shack surprisingly landed in the new world in one piece. "This place does not seem that unfamiliar." Mabel told as she cuddled her pig.

"Must be some silly wormhole shenanigan. It just brought us back! What gives?" Stan scoffed. "Well, I don't think so, Stan." Ford said without glancing away from the device in his hands. "My dimension indicator is going out like crazy and I can't figure out what went wrong with it." He adds.
