Authors Note: Gravity Falls and Phineas and Ferb crossover! Oh yeah! xD Since I can't just do a Gravity Falls fanfic yet, why don't I do both before I completely make the switch over. Who knows? Maybe I'll get an idea. This is my FIRST story that doesn't completely focus around Phineas and Ferb. Don't flame, tell me if I'm doing ok x) Happy Birthday WordNerb93!

Okay it's not your birthday but it is a present to you nonetheless!

"Road trip! Road trip! Road trip! Road trip!" Mabel chanted, bumping both her fists in the air.

Dipper groaned in his seat in the back of the car. "I don't know about you Mabel but I'm not really up for a surprise road trip at five in the morning…why're we even going on a surprise road trip in the first place? Where are we going?"

"Grunkle Stan said we're going to this Swap Meet in a place called The Tri State Area." She waved her fingers mysteriously and then smiled "He can sell ridiculous things at high prices!"

"Another scam, huh?" The boy rolled his eyes.

"It's not a scam." Stan glared once he got in the driver's seat, he had just finished loading up a sign that read 'Scam Stand' into the trunk. "It's a reasonable business trip…" A pause. "Hey does this look like an antique to you?" He held up a broken and dirty lamp.

Dipper sighed and laid down in his seat "Wake me up when we get there." He closed his eyes but he didn't sleep for a second between Mabel singing show tunes and his great uncle thinking of prices for his junk out loud. Hours had passed and they finally pulled to a stop. The Tri State Area sure was far away from where they lived.

"We're here." Their uncle said and started unpacking things from his car.

Mabel squealed and unbuckled her seat belt "Isn't this exciting Dipper? A whole new place! It's so BIG!"

He sat up from his lying position and unbuckled his seatbelt, staring out the window at the large buildings. This place sure was different from where they lived…

"What are you waiting for?!" His sister asked him "Let's go!"

Before Dipper had a chance to protest, he was being pulled out of the car and dragged into the Swap Meet. Grunkle Stan started setting up his stand.

"Hey Grunkle Stan, who's watching the shack back at our place?" Dipper asked.

"Oh don't worry, Soos is watching it for me. He said he'd guard it with his life." Stan waved it off.

At the Mystery Shack.

Lil Gideon's father tiptoed past a sleeping Soos who was leaning up against the outside of the Shack. He opened a window and snuck in, he fell inside with a loud crash. Soos stirred but didn't awaken.

Back in Danville.

"I'd better call Wendy…just in case." Dipper started dialing on his cell phone that I'm assuming he has. Wendy answered and the two started talking, his voice faded in Mabel's ears as she spotted something orange and teal on all fours.

"Woah…" She was amazed by the little creature, she'd never seen one before. It was so cool! "Dipper, look at that!"

"Yeah…Hang on a sec Mabel…" Was his distracted reply to his sister as he continued with his phone call.

Mabel gasped when she saw it stand up on two legs and put on a hat. It started running and she just had to follow it. She walked off in the direction it went.

"Alright, thanks bye." He pocketed his phone and turned to his uncle. "Wendy said she'd check up on Soos later."

"Huh? Yeah sure whatever…" Stan replied as if he could care less and continued setting up his stand.

"Okay Mabel now what was it you wanted to show me? Mabel?" Dipper turned to the spot where his sister had once been to see that she wasn't there anymore "Mabel?" He turned around just in time to see her running full speed down the street, he sighed and ran after her; calling her name. Yep, this was going to be a fun day.

...

Perry ran faster down the street. He was being chased and he didn't know by what or who. He had put on his fedora and gotten the feeling that he was being watched. He started running and that's when he knew something was following him. He heard the footsteps fall closer behind him, the platypus turned a corner and soon he was running for his life. The agent came to the conclusion that whatever was chasing him wasn't more than 4 feet tall so it wasn't a man or woman from LOVEMUFFIN...Unless Dr. Diminutive was the one chasing him, but Dr. Diminutive was scared of him. Why would the small man be chasing him all alone if he were scared of him? There were only two small feet behind him so they were standing on their hind legs and that also let him know that it was only one individual after him. It couldn't be an animal, at least no animal he knew. Every once in a while it would make this feminine squealing noise. What was this horrid thing and why was it after him?

"Come back!"

Oh mother of platypi, it talks!

…

"Mabel!" Dipper called and ran after her. Why on earth was she running?

…

"Come back!" Mabel yelled after the thing, her own scream covered up her brothers so she didn't hear him calling after her. She was tired but she couldn't let it go, it was all alone! Who would help it? She followed the little blue animal until an oddly shaped and large purple building was in sight. It looked like one of those buildings that owned a large company. Doofenshmirtz Evil Incorporated? What type of company was that?

They were right in front of the building now and with all the energy she had left, she jumped and tackled the thing to the ground.

"Got you!" She smiled.

"MABEL!"

To Be Continued…

What do ya think? The chapters will be short but then again, it's a short story.

NattyMc is out, PEACE!
