Hey guys! This is my first fanfic. I decided to combine two great Disney Channel shows, new and old. Enjoy!

Chapter 1

Jake was bummed.

His summer wasn't turning out to be as great as he had hoped. Sure, he had gotten to go to Hong Kong and see Rose, his new international girlfriend. He had finally defeated the Dark Dragon- or entombed him for another thousand years, at least. And his dad had finally found out the family secret, which proved to be really helpful now that he wasn't getting grounded for every single dragon emergency.

But still... he hadn't been prepared for this.

He had recently been informed that he would be spending the summer at his paternal great uncle Stan's house in a dumpy little town called Gravity Falls, Oregon. His mom had decided that he and Haley could use some time away from the big city. Luckily, though, after three days of begging, Jake had finally persuaded his mom to let him bring Trixie and Spud with him.

His mom had also explained that he would be meeting some cousins for the first time. They had been staying at Gravity Falls for a few weeks already. She hadn't told him their names, or how old they were.

Jake was still remembering the conversation as stared out the window of the plane, flying to Oregon. Suddenly he was interrupted by Trixie, who was sitting next to him.

"Jakey!" she said. "Isn't this exciting? We're going to Oregon, baby! The Great Outdoors, ya know?"

Jake raised an eyebrow. "You're only happy because you won't have to sleep outside in a tent again."

She scoffed. "Why would you accuse me of such-"

"Because you said it in the car on the way to the airport."

They looked at Spud, who had just interrupted from across the aisle. He was sitting next to Haley, who had been rambling away about who-knows-what.

Trixie cleared her throat. "Well, I don't remember everything I mentioned in the-"

Jake tapped the window, and an image of the kids in the car simmered into existence. As they watched, past-Trixie repeated everything she had just denied saying.

"Thank you, Gramps." Jake smiled as the image disappeared.

Trixie blushed. "You think you're so smart, Jake Long."

"Yeah, Jake," Spud agreed. "That's my job."

Haley decided to join the conversation. "So Jake," she tried, "what do we do if dragon business comes up?"

Jake waved a hand. "Nothing's going to happen, Hales. When has anything magical ever happened outside the NYC?"

"You mean other than the Magus Bazaar, the Isle of Draco, Afghanistan, Switzerland, Guatemala, New Jersey, Hong Kong, alternate universes, sixteen other dimensions, and a dream corridor?"

"Where did Afghanistan, Switzerland, and Guatemala come from?"

Haley waved a hand nonchalantly. "We're talking dragons here, Jake. It's safe to just throw in a few random countries."

Just then, the captain's voice came on the PA, explaining that they were beginning their descent in Bly, Oregon.

Shortly after they landed, they gathered their suitcase from the luggage carousel. They were about to leave, but Haley facepalmed herself. "Fu!"

Yes, the 600-year-old Shar Pei had tagged along. Gramps had insisted he come to keep the four kids out of trouble. Unfortunately, he'd had to ride in a kennel.

They went back for him, and arrived in the nick of time. Fu had just started yelling at the man carrying him away, quickly covering it up with "Uh, I mean... woof?" They retrieved him, and he spoke up as they walked outside.

"Geez, kids!" he complained. "I'm not that ugly!"

Haley shrugged and shook her hand in a so-so motion, and Jake laughed.

"Oh, very funny!"

They looked around for someone who would be picking them up, when Haley pointed. "There!"

Sure enough, there was a man standing a few yards, away holding a sign that said "Long and other dudes." The man had a brown cap, beige cargo shorts, dark brown shoes, and a jade green shirt with a big question mark on the front. He had light peach skin and buck teeth, like a beaver's. He was also fairly chubby, and he had a double chin.

"Woah, dudes," he said casually, and Jake noticed that he had a fat-lisp. "You must be the Longs. Stan told me about you. And who are these two?"

Trixie and Spud introduced themselves.

"Whoa, Spud?" the man asked. "Man, weird names are just popular these days! Like mine! I'm Soos."

"Nice to meet you, Soos," Jake said. "So, are you a friend of Uncle Stan, or..."

Soos chuckled. "I'll explain on the way." He turned to get back in the car, and Jake noticed the back of his shirt said "Staff" on it.

"You see," Soos said as they drove away from the airport, "Mr. Pines transformed his house into a tourist attraction called The Mystery Shack. I've been working there since I was twelve."

Haley gave a skeptical look. "Tourist attraction or tourist trap?"

Soos shrugged. "It's best not to question it."

"It's a whole union thing, it's complicated," Spud said, repeating what he had told Haley a while back.

Haley giggled.

"Anyway," Soos continued, "I work there with a few other people. The uze, you know."

They finally arrived at the Shack, and Jake got out of the car to look at it. It was shabby, for one thing, and it had a sign on the roof that said "MYSTERY HACK" because the "S" had fallen onto the lower roof. For some reason, there was also a goat on the roof.

"Nice digs," he commented.

Soos smiled proudly. "You guys ain't seen nothin' yet! Come with me!" With that, he marched toward the Shack. The kids, not forgetting to retrieve Fu from the trunk, followed suit.

They walked through the front door into a gift shop of some sort. There was the basic stuff- like bobbleheads, hats, and t-shirts- but there was also a collection of all kinds of seemingly supernatural items, and Jake noted that pretty much everything there was fake.

Sitting at the register was a lanky girl reading a magazine. She had long straight red hair that was covered on the top by a tan-and-black lumberjack hat. She had green eyes, fairly pale skin, and freckles. She wore a jade plaid buttoned shirt with a white tank top underneath, blue jeans, blue-gray stud earrings, and muddy rain boots. Jake could see her boots because her feet were propped up on the counter.

She vaguely noticed the group, then started speaking in a monotone: "Welcome to the Mystery Shack, the exhibit of the extraordinary, the museum of the mysterious, the gallery of the-"

Soos cleared his throat.

She looked up, then sighed in relief. "Oh, good. It's you, Soos. I forgot the alliteration for g."

Spud raised a hand. "Was it gruesome?"

The girl snapped her fingers. "That's it!"

Jake noticed that she had a nametag on her short that read Wendy. "You're Wendy, I'm guessing?"

She glanced at her nametag, then smiled sheepishly. "Oh. Well, yeah, I am. Who are you guys?"

"These are my niece and nephew!"

The group looked at a man coming out of a room marked Employees Only. He was obviously aged, as he had gray eyebrows and a gray five o'clock shadow on his lower face. Jake assumed he had gray hair, but his head was covered by a maroon fez with a yellow moon-like symbol on it. His reddish nose was strangely large. He had an unnecessary eyepatch over one of his glasses-wearing brown eyes, and he was obviously dressed for show. He wore a black suit with the jacket buttoned closed, a bowtie the same color as his fez, a white dress shirt, and big light brown shoes. Also, he was carrying a brown cane with a magic eight-ball on the end.

"Uncle Stan!" Jake said, remembering him from his youth.

It was indeed his great uncle Stanford Pines. "How's it hangin', Jake?" he replied. He turned to Haley. "And Haley, we've never met. Jake was just a baby!"

She smiled, then shook his hand. "Nice to meet you."

Wendy frowned. "They look nothing like you."

"Neither do the twins," Soos reminded her.

Jake raised an eyebrow. "Twins? Our cousins are twins?"

Stan smiled mischievously. "Oh, that's right. You haven't met the twins yet." He poked his head into the room he had just come from. "Hey knuckleheads! Get down here!"

Jake realized that the back room must be pretty big if Stan had to yell. That must have been where he lived.

"Coming, Grunckle Stan!" It was a girl's voice.

"Grunckle?" Spud cocked his head.

Stan shrugged. "The kids made it up. It's a mix of great and uncle."

"Oh. That makes sense. I guess."

Two short kids, a boy and a girl, emerged from the back room. The boy had a trademark blue and white hat with a blue brim and blue pine tree on the front. He had somewhat messy brown hair and relatively pale skin. His eyes were brown, and he had slightly noticeable bags underneath. He wore a navy blue vest, a reddish-orange shirt, gray shorts, white socks, black sneakers, and a gray wristwatch on his right wrist.

The girl was obviously the boy's twin. Her cheeks were round with blush pink spots, and her hair and eyes were brown, like the boy's. She wore a pink sweater with a rainbow shooting star going in the left direction on it, a matching pink headband, a purple skirt, white socks, and black shoes.

"What is it, Grunckle Stan?" the boy asked.

Stan gestured to the Longs. "These are your cousins that are going to be staying with us. And friends."

The girl perked up. "Oh! You're Jake and Haley!" She rushed forward and extended her hand. "I'm Mabel!"

Jake took her hand. "Nice to meet you." Haley did likewise.

Jake looked at the boy, who was just watching and taking it all in stride, like he was used to Mabel's antics. He realized that they were waiting for him, and he walked forward as well.

"Oh, sorry. I'm Dipper." He extended his hand also.

"Dipper?" Spud scratched his head. "You were right, Soos. Weird names are popular these days! It's even weirder than mine!"

Trixie smacked him. "Spud! Don't say that!"

Dipper looked at his feet. "That's the reaction I normally get."

"Same here," Spud agreed. He and Trixie introduced themselves to the twins.

Mabel beamed, and Jake saw that she had silver braces. "Come on! I'll show you where you'll be staying!"

She led the group into the back room, which actually was a house on the inside. The entryway was a living room that was about as odd as the gift shop. Next to the orange easy chair was a fake dinosaur skull. The fish tank had two shrunken heads resting on it. The owl clock on the side wall didn't seem to be working. Weirdest of all, Jake concluded, was the rug on the shag carpet. What was the point?

They followed her up the stairs to a hallway, where there were two doors. Jake started to walk into the first one, but Dipper surged in front, standing between Jake and the door.

"Don't!" he cried. Then he realized that they were staring at him.

"Oh, don't mind Dipper," Mabel said. "That's just the room where we fought the-"

"The flu!" Dipper interrupted. "Uh, we were fighting the flu in that room just two days ago! It's probably still contagious, so we shouldn't go in."

Jake knew right off the bat that Dipper was hiding something- considering how hard it is to catch the flu in the summer- but he also knew not to intrude on private matters, so he shrugged and continued after Mabel to the second door. It was elaborately carved, and it was so wide that one could easily fit a baby elephant through the threshold. Mabel pushed it open and walked in, and the kids followed.

"This is Soos' break room," Mabel explained. "He gave it up temporarily so you guys could have somewhere to stay. It's like a giant sleepover!"

"This is a pretty big room," Spud commented. "But the floor is hard. Could you, like, put down a carpet or something?"

Mabel looked at Dipper accusingly. "Well, we had one in here. But someone made Grunckle Stan throw it out!" She leaned in toward Spud and whispered, "It was Dipper."

Dipper spread his arms innocently. "Well, I'm sorry for throwing out a carpet that-" He glanced at the Longs. "Uh, uh, had moths in it! Yeah!"

Again, Jake got the impression that Dipper was hiding something, but he decided to worry about that later.

"Come on," Mabel said, dragging Dipper out of the room. "Let's give them time to set up."

"We'll be here all week, folks!" Dipper yelled hastily.
