~~~~~~~~~~~~~✏~~~~~~~~~~~~

You're (y/n) Pines, 20 year old sister of Dipper and Mable Pines. You three were unseprable, that is until it came to summer. It started back in 2012 when you had the opportunity to go to (f/s) camp for the summer. But sadly Dipper and Mable couldn't come so your parents sent them to your great uncle who you have had yet to meet. After that year of summer though they changed. They were still themselves but they became more secretive and they wouldn't hang out anymore. At first you thought that they just missed Gravity Falls, but it continued before you finally asked them what was with them out of worry only for them to insist that it was nothing. After that you dropped it. Sadly you couldn't go with them for five years to Gravity Falls because of family drama. But now finally you get to go with your siblings to Gravity Falls for the first time.

You sat with your (f/c) backpack with (s/c/f) designs and zippers with your favorite characters as keychains hanging off them and pins decorating it. You had a dark hoodie, sneakers, and jeans on and your headphones on your ears listening to (f/g) to pass the time from driving to Oregon. You had a sketch book in your lap, a mechanical pencil in your hand as you observed your picture. It was a man who has six arms all producing blue fire, a smile on his face with one eye covered with a upside down triangle. The figure itself was filled in black with a main white outline while other parts had yellow and other colors. It was a picture you made in your sleep. You flipped through the already finished pictures, flashed of golds, blacks, and blues was mainly what you saw. Not only were they of the same person, they were all drawn and colored or in some cases painted in your sleep. This is something that has been happening since you turned eight years old. It was a daily basis to wake up out of your bed with your head laying on your desk you had in your room, your hands covered in graphite, paint, or smudges of colored pencils, and a newly drawn picture in your sketch book.

You closed your dream sketch book, stuffing it along with your pencil into your back pack noticing a sign stating 'Welcome to Gravity Falls, Nothing to see here'. Next to it was... Is that a gnome...? Your just shrug your shoulders thinking it was fake and continue to watch the greenery slide by.

Dipper and Mable were already at the there, leaving you to come on your own. It was odd, but then again they always were that way whenever something involve Gravity Falls.

After a bit the bus stopped, waiting for you as you walked off, pausing your music and sliding your headphones down to hang around your neck. The moment you stepped onto the sidewalk, the bus driver closed the doors and drove away. You looked around until you spotted a red 1965 El Diablo convertible. An older man sitting in the front with two people who you instantly recognized as your two siblings.

Dipper was sitting in front, still having the same blue and white Pine Tree hat that he's had ever since he first came back along with a red/orange shirt and dark blue vest, zipped up halfway. He had his head stuck in a journal, one that you have never seen before, with a blue cover, slightly torn edges. In the middle of the front cover was a gold pine tree with the number 4 in the middle. Mable was sitting in the back with a red and purple star sweater, and pink headband.

You started walking towards them. A smile grew on your face as they saw you approaching. Dipper immediately stuffs the journal he was writing in away into a pocket on the inside of his blue vest before stepping out of the car and started walking to you calmly. Mable did the opposite by literally jumping out of the car and sprinting at you, crushing you with her well known bear hugs. You chuckled a little, wrapping your arms around her and returning the hug. When she released you, Dipper hugged you and was much more gentle which you still gladly accepted.

When he released you, you chuckled a little more, "It's only been a day, did you guys miss me this much?"

Dipper chuckled, about to say something before being interrupted by a rather loud voice that came from your right. "Hey kiddo, I'm your great uncle Stan, but you can call me Grunkle Stan." You look to your right to be met with the man that was driving the car. He had grey hair, glasses with small cracks in it, and shorts with a button up shirt, looking like he was going on vacation in a way and was holding his hand out for you to shake.

You smiled his way before grabbing his hand, giving a semi firm shake. "Nice to finally meet you Grunkle Stan. A certain pair of twins couldn't shut their mouths about you." He smiled back at you before heading back to the car, starting up the engine.

"(Y/N)!! You need to meet my friends!!! Come on!" Mabel practically yelled into your ear before grabbing your forearm, very harshly, causing you to flinch, before dragging you into the back seat of the convertible with her. Dipper came into the front seat after you and Mable got buckled into your seats, him getting buckled as well. You set your backpack on top of your lap, unzipping the middle pocket to reveal small chip bags, cookies and snacks galore. You pulled out your favorite kind of chips, opening it and started munching on its salty deliciousness.

When you look out the window you can see the town of Gravity Falls, seeing a diner, mall, a water tower with a... muffin? spray painted on it and a forest, which you guys were headed to. The road then went from smooth assault to a bumpy dirt road. The forest surrounded the road, casting shadows and showing you in all of its glory the beauty of nature. You admired the small animals you saw running into the frorest, even seeing the occasional deer and fox until the road lead to a clearing of land. It had a totem pole and a house. The house itself was two to three stories tall with large letters that spelled 'MYSTERY _HACK' with a S laying on the roof. There was moss patches on it and another sign that was circular that said 'World Famous' on a smaller part of the house on the side with the gift shop on it. The whole thing just screamed tourist trap.

Grunkle Stan parked his car next to a golf cart and took the key out of its ignition. You all stepped out of the car, taking your now empty bag of chips, and bag and walked to the gift shop. When you all waked in you see a man that was in a black suit with a tie that was tied into a bow and having a red fez on top of his head with a golden fish on it. He kind of looked like a man baby for some reason. You looked over to the cashier counter to see a tall girl that looked your age, maybe just a tad older, with red hair, a green flannel button up shirt, some jeans and boots that had some dried mud covering the bottom. She had her legs crossed, resting on top of the counter and her head in a magazine of some sorts.

You looked around the room to see all sorts of cheap toys and t-shirts that were way to over priced and a vending machine. Then all of a sudden the vending machine opened revealing a passage in the wall revealing a man that looks quite similar to Grunkle Stan. Stan's doppler ganger turned to you three, sending a smile Dippers way before taking a journal similar to the one Dipper had except with a 3 on it instead of a 4 and with a golden six fingered hand.

Dipper turned to you, pointing to the mysterious vending machine guy. "This is Great Uncle Ford. Uncle Ford, this is our older sister (y/n)." You waved his way, sending a smile while he nodded his head back at you, looking very serious unlike Stans laid back demenior. Dipper then moved his hand, pointing around the room,
"Welcome to the Mystery Shack."
