One day on a quiet but yet weird town of Gravity Falls in a tourist trap, two twins Dipper and Mable Pines are watching the latest episode of Ducktective Mabel is getting into the episode while Dipper is getting some mile joy out of it. In the episode, the Ducktective looks around for clues in a pub with a cop.

"You're not going to find anything in this pub that the other men on the force couldn't find," said the cop

"Quack Quack Quack Quack (There something that other officers didn't see in this pub)," said Ducktective

"Oh what could that be?" the cop put his hands on his hip

"Quack (this)," Ducktective steps on a false floor tile causing a bookcase in the pub swings open to reveal a staircase

"My word," the cop was stunned

Ducktective and the police walk down the stairs while Mabel eats some popcorn as the scene goes on, feeling the tension as Dipper rolls his eyes.

"I could have figured that out," Dipper thought

"Oh god, what could be at the bottom of the staircase, Dipper? the murder weapon?" said Mabel

"Or it could be the killer's hideout, Mabel," said Dipper

The Ducktective and the cop reach to the bottom of the staircase to see various photos of the murder victim, a bed, weapons, and a table full of papers and a pitch of water.

"This must be the murders hideout," said the cop

"Told you," said Dipper

Then Ducktective goes to a photo of the queen of England with a circle around her head.

"Oh my god the murder is going to come after the queen next," said the cop

"Quack Quack Quack Quack Quack (then we must warn the queen before it's too late)," said the Ducktective

Then show cuts to a commercial to a new Sumo Slammers card collection later in the summer.

"Wow this turning out to be a great episode," said Mabel

"I think it's okay," said Dipper

"Oh, c'mon Dipper the murder is going to try to kill the queen of England,"

"She probably not going to die once the Ducktective stops the killer before he even gets near the queen,"

"I have you seen this episode before?"

"No, I'm just guessing what happens how this episode is going to happen,"

"Moving on how you and your mystery hunt lately," said Mable eating some of her popcorn

"Aw, nothing major has come up just one thing that seems to be trending around town,"

"What is it?"

"That some household items have gone missing and some people devices haven't been working for the past few days,"

"Anything from the journal?"

"Nope, no creatures in the journal steal stuff unless it's souls or quarters,"

"Quarters? Who steal quarters?"

"Fairies,"

"Really, there, fairies!" Mabel got excited "I can have fairy as a friend,"

"Yeah Mabel the fairies are usually deep in the woods, and they have their hiding place, so they are hard to find,"

"Oh man,"

As the twins continue to watch the Tv show until their Great uncle Stan comes into the room.

"All right, I need one of you two to go into the town for me and go to the post office to get a package," said Stan

"What is the package?" said Dipper

"It's something vital for me and the mystery shack so which one of you is going into town,"

"Paper, rock, and scissor Mabel,"

"Sure Dipper," said Mabel

Dipper and Mabel play a quick game of paper, rock, and scissor, and the loser would go and get Stan package Dipper has rock but Mabel paper.

"I win," said Mabel

"Fine, I'll go get the package," said Dipper standing up and was about to head out

Stan calls Dipper out before he goes "and you got to be careful with the package it's very fragile,"

"Got it!" Dipper shout back as left the shack

Mabel goes back to watching Ducktective, and he confronts the killer to be Ducktective's old friend from high school, and Mabel was shocked.

"I did not see that coming, and he was so nice,"

Dipper comes to the post office, and he gets Stan's package that was an old wooden box that has some accident language all around it.

"What the heck did Stan order," Dipper lock around the box to see no further information on it "whatever it is I hope Stan doesn't get myself in trouble with this,"

Dipper leaves the post office as he heads back home to give Stan his package but then sees a redhead girl around his age wearing a blue long sleeve shirt with a cat symbol on it, white pants, and white shoes. She was next to a tan Rv with red stripes on it, and she was holding a map, and she seemed to be lost. Dipper decided to be a good samaritan and help her out.

Dipper comes up to her "excuse me,"

The redhead turns around "oh yes,"

"I notice you look lost when you're looking at the map anything I can help you out,"

"Yeah my grandpa is trying to find the town mall, and we can't seem to find it,"

"Let me see the map," the girl hands Dipper the map "all you have to do is turn left on a few corners, and you'll be there," Dipper hands back the map to her

"Thanks,"

"No problem I hope you have a good time in Gravity Falls even if it can get kinda weird," Dipper leaves the girl and heads back to Gravity Falls

The girl thought "he was helpful and kinda cute,"

Then she heard a whistling noise behind her, and she turned around to see her brunette cousin with a grin.

"So Gwen who is your newest crush," her cousin tease

Gwen blushed a bit "shut it, Ben, and he was just helping me out that's all,"

"Sure he was," Ben snicker a bit

"Ben and Gwen I got the tools," the cousin turn around to see their Grandpa Max holding a bag of tools

"I got the direction to the mall," said Gwen

"Great, we can get something for dinner tonight," Max opens the Rv door, and everyone gets in the Rv and Max start's the Rv up and drives to the mall.
