Hey my comets! This is my very first fanfic so please don't hate on me if it isn't that good. I do NOT own Gravity Falls or this AU, the show belongs to Alex Hirsch (sorry if I spelled that wrong) and the AU belongs to everyone. Hope you guys enjoy!
Dipper unpacked his bags and sat down on the bed in the attic. He smiled in ecstasy; it felt good to be back. He headed downstairs to the gift shop where he looked out the window at the party supplies Soos bought. Mabel and he had just returned to Gravity Falls so Soos decided to celebrate with a "welcome back" party. Great Uncle Ford and Grunkle Stan had also returned for a few days to say hi to the kids and check on a weirdness bonanza that Ford's instruments had picked up on. Dipper looked around and was about to leave when he heard a familiar voice.
"Pine Tree, Pine Tree, so strong and fierce. Brave as a centaur and quick as a deer. Better watch out, I'm not gone for good, enjoy the Fluvious waters in the dark woods." It said, raising the hair on the back of Dipper's neck; there was only one person who called him that. Or rather, one demon. Dipper looked around in fear for the triangular menace when the rug beneath him began to glow with a golden light while laughter came from all around.
"I tell you this because you're my favorite of the Pines, so watch out for werewolves or you'll meet your demise!" As if that phrase was a trigger, the rug below Dipper began to float in the air taking him with it. Mabel walked in holding a list while chewing on the Squish 'Em eraser on her pencil.
"Okay Dipper, we need to make sure that we aren't forgetting anything for the party. Did you get the-WAAAAHHHH!" She screamed as she looked up at the weirdness around her. She ran, grabbed Dipper off the rug, then ran out the door. When they got outside, they slammed the door and leaned against it. Mabel turned to Dipper and shouted, "What was that?!" As she said this, Ford walked over to find out what the commotion was.
He looked at the shaking twins and asked, "What happened?"
Dipper looked Ford in the eye and replied, "Bill happened." Before he could elaborate, Wendy walked over and asked, "What's this about Bill; didn't we erase that jerk?" As Dipper opened his mouth to answer, demonic laughter rang out and the door behind the twins was blown away with the four in front with it. Dipper flew against the ground a few yards away and groaned as he rolled onto his back and pushed himself up onto his elbows. A dark fog rolled out of the shack towards the boy and a golden figure floated along the fog.
Bill rose above Dipper and said "Pine Tree, dangers around you will soon call, prepare for the weirdness that is GRAVITY FALLS!" And with that, the fog and the demon blew away in the wind.
Everyone there stood or laid, respectively, with slack-jawed fear and horror as they contemplated what had just happened until Ford broke the silence and asked, "What exactly did Bill say to you inside?" Dipper blinked and told Ford word for word what he had been stood there, then pulled out his journal to look in it for information.
"I faintly recall something called Fluvious, but I might have to do a bit of research on it." Ford remarked as he flipped through the pages. Dipper looked towards the forest to see a strange glow lighting up a path, and a pull towards the path. He walked over to it and checked around to see what was making it glow like that, the path seemed to emit the light itself. Dipper felt the pull grow as he ran down the path deeper into the forest. Mabel looked around for her brother to comfort him when she saw the path in the wood and Dipper running down it.
"Dipper! Wait for me!" She shouted as she ran down to and onto the path. A voice echoed through the woods, making Mabel feel fear and a sense of paralysis.
"Shooting Star, Shooting Star, a mermaid is what you are. Enjoy your brother while he's here, very soon he'll disappear!" Mabel didn't know what it meant, but it was something that she really didn't like. The twins finally reached a darkened clearing with bioluminescent fungi illuminating a long, deep, silvery river. Dipper walked over to it as the pull he felt dissipated, followed by Mabel who was beginning to freak out.
"So, do you even know where we are?" She asked Dipper who was down by the water checking out the shining surface, as she asked this a voice rang out behind them.
"You're exactly where I wanted you to be." Mabel and Dipper whipped around to see a tall man with blonde hair, a golden tuxedo with brick print along the base, a thin black top hat, and glowing yellow eyes with cat-like slits for pupils. The twins backed away slowly as the strange man edged closer.
Dipper's eyes widened as he realized who the man was and he finally sputtered out, "B-Bill?!"
"In the flesh! Although this wasn't how I expected it to happen; I was hoping more along the lines that the added weirdness from you two would give me my physical form back, but I still have my powers. They even grew since they aren't holding me in that old form, so for that I must thank you!" He replied with a sadistic grin as he conjured blue flames that licked his hands and encroached on the twins. They stepped back into the river and fell in with a terrified scream. Dipper's head broke the water's surface a few yards away, right before Mabel's, and saw the face of Bill's still grinning face watch as the twins floated away.
When Bill's face was no longer visible, Dipper grabbed Mabel's arm and pulled her over to the bank. They climbed up to the grass and laid down to see the red-stained sky in between the pine needles of the trees. The last thing Dipper saw was Bill walking towards them.
Dipper awoke with pain beside his sister to see Bill walking into the forest nearby. He grabbed his twin, picked her up, and carried her inside on trembling legs to find Wendy restocking the gift shop. She looked over in time to see Dipper pass out from pain and exhaustion. She dropped a snowglobe with a gasp and ran over to the banged up twins. She picked them up and ran into the living room to find Ford who was pouring over the journals in an attempt to find something about Fluvious. He looked up with a disgruntled face that rapidly changed into one of fear as he saw the kids hanging off of Wendy.
"What happened to them?" Ford asked as he helped Wendy to set the twins on the ground.
"I don't know! I was restocking when I saw Dipper carry Mabel in and pass out on the floor!" She replied in a huff. Ford grabbed some weirdness detection equipment and hooked it up to Dipper and Mabel as they began to glow.
The twins began to thrash and groan as Ford scanned them with his instruments, their glow brightening slightly. Wendy stood over the pair, holding them down so they wouldn't hurt themselves. Suddenly, Mabel's legs lengthened and began to fuse while she whimpered in pain. Dipper rolled on his side and let out an earsplitting scream of agony that echoed through the woods as his ears glowed and lengthened while his legs thinned and stretched to produce two more. Ford covered his ears and looked at his instruments to see that they were scrambled from the weirdness levels. Wendy fell backwards, blood streaming from her nose and ears while the scream of pain subsided.

In Greasy's Diner, a scream sliced through the air shattering coffee mugs and glass, everyone ducked and covered their ears. When the cacophony finally subsided, Lazy Susan sat up and exclaimed, "What was that?!" Soos and Stan looked at the carnage in their food and bolted, heading towards the Shack. "I know that scream anywhere, something must have happened to Dipper!" Stan said to Soos, who replied, "Yeah dude, he's probably the only dude in the world that screams like that!" As they reached the shack, Stan threw open the door and reached the living room in time to see a bright glow subside revealing Mabel with a large fish butt and Dipper on top of a deer body, both passed out. He looked over at Ford who was sitting down with an image of pure shock and horror on his face and asked, "What. Happened."

In the forest, a screech of suffering destroyed the peace and scared all the forest creatures into hiding. Bill stopped as he heard the sound and dropped to his knees, covering his ears. When the sound finally stopped, he looked up and around, then smiled and remarked, "Well, I think that's a record for pain, but records are made to be broken; Pine Tree hasn't seen anything yet." As he said this, a blue flame enveloped his body and he let out a demonic cackle
Okay, so that was actually difficult to write without freaking myself out... Anyways, I hope you liked that chapter! Enjoy the next one, or else.
