After a little shopping at Gravity Falls mall, Tennyson's come back to the Rustbucket with Grandpa Max has a bag full of strange food that includes a squid that he is going to make for dinner much to the dismay of Gwen and Ben.
"God squid burgers again," said Gwen sitting down on the couch
"I don't have any snack with me that would knock the taste of squid out of my mouth," said Ben sitting down next to her
"At least we're going to Seattle where there are tons of things to do there like the parks and museums,"
"And of course Seattle has one of the best comic book shops in the U.S.," Ben smiled and put his arms behind his head
"Comics is that the only thing you look forward to in Seattle, Ben?"
"Of course there nothing else in Seattle is interesting to me," closes his eyes
"How about the Museum of Pop Culture where they have a bunch of indies video games,"
The museum with videogames got Ben to open his eyes "Now you're talking my language, Gwen,"
Max gets into the driver seat of the Rv and strips in "all right Seattle here we go," Max drives the rust bucket out of the mall parking lot
Back in the mystery shack, Dipper hands Stan his package as he smiled when he got his hands on it, and Mabel walks in to see Stan's package.
"So that package, what is it?" said Mabel
"This is the box of wonders, and I read off the internet that it does wonders," said Stan
"Like what?" said Dipper
"For example, it could make me young again," Stan open the box and there was a blue flask with a clear liquid inside
"Should we research the effect the box does before we drink something unknown from it,"
"Nonsense Dipper I got this besides what the worse could happen,"
"Oh no he says those curse words you never say," said Mabel
Stan drinks the clear liquid until the flash is empty, "so do I look young or what?"
"Nope, your still our lovable old grunkle Stan,"
"Dang it, I knew this thing was a ripoff," Stan throws the bottle in the trash, but he didn't notice some of his hair rising from his chest and popping out of his white beater
"Um Stan you might want to go look in the mirror," said Dipper
Stan got excited, "wait, did it work? Am I young again!"
"No, but you got more chest hair,"
"What!" Stan goes to the bathroom to see that his chest hair has grown bigger and hairier "crap! quick kids give me a Razor and tons of shaving cream,"
"On it," said Mabel heading toward Stan room
Dipper looks at the box of wonder to find a notecard inside, and Dipper reads it.
"The box of wonder sometimes does not give you what you want,"
"Whelp this bite Stan in the butt," Dipper thought
Mabel comes back with a razor and large shaving cream and hands to Stan "here you go Grunkle Stan,"
"God this is going to take hours to shave off it's a good thing that there are no customers at this hour," said Stan taking off his white beater and the twins hold in their lunches seeing there grunkle old men body
"All right think I'm going somewhere else," said Dipper
"I'm with you Dipper," said Mabel going with Dipper and away from Stan shaving his chest hair off
Later on the day, The rust bucket was working correctly until the Rv engine started to make a sound strange and started to slow down, making Grandpa Maz pull the Rv over on the side of the road.
"Grandpa what's wrong?" said Gwen
"It's Rustbucket something wrong with the engine," said Max
"I can fix it with Gray matter or Upgrade," said Ben hover his hand over the Omnitrix
"No thanks Ben I think I got it," Max heads out of the door to see what the problem
"Wonder why grandpa didn't want my aliens to help?"
"Seeing how we're keeping a low profile I would say it look strange for a little alien fixing an Rv," said Gwen
"I could have been careful," Ben cross his arms
Grandpa Max opens the Rv hood and Immediately sees what is wrong with the Rv as he sees most of the Rv engine parts are missing and have been replaced with phony parts.
"How in the world did this happen," Max thought then he look around to see any place nearby where he spots the Mystery Shack down the road "I could get some help there but better tell Ben and Gwen first,"
Max goes back into the rust bucket and informs Gwen and Ben what about the situation, and he heads back out and walks to the Mystery Shack he sees the S for the sign has fallen off.
"Is it supposed to be like that," Max thought he shrugs his shoulder and knocks on the door
The door opens to Stan in his suit and fake eye patch "ah I see what got a customer for this afternoon tour of the Mystery Shack,"
"No my Rv has broken down I just need a phone to call a mechanic from town,"
"Oh sorry but the nearest auto shop is out of town,"
"Really,"
"Yep but I know I guy who handy with any type of automobile which can help you out with your Rv,"
"That kind of you,"
"But you have to go on the gravity fall tour for me to call me,"
"Are you serious,"
"Hey, I got business to run, so do we have a deal?"
Max sighs "fine I'll go get my grandkids for this tour,"
"Hey, the more, the merrier," than Stan thought "the more money,"
Max gots Ben and Gwen out of the rust bucket and into the Mystery Shack onto Stan tour of the hovel where Ben and Gwen were not enjoying the tour at all.
"Men none of this are even real," Ben whispered to Gwen
"No kidding I'm pretty sure he just glue an eyeball to a fake leg" Gwen whispered back
Stan stopped at the Unknown display, "and this is the unknown a mystery that no one seems to know what it is,"
"What you think it is?" said Ben
"I think I'm some strange glob monster that nature created and left abandon," Stan try to sound mysterious
"Yeah right," Gwen thought
At the end of the tour, Stan takes Ben, Gwen, and Max to the gift shop where the clerk Wendy is reading a magazine, and Dipper and Mable are stocking the display.
"Now you guys can shop at the gift shop," said Stan
"What about the phone call to your guy?" said Max
"Fine come with me," Stan take Max to a phone while Ben and Gwen look around the gift shop
Gwen looked at the question mark shop and not looking she bumps into someone "sorry about that,"
Gwen see to the person she bumps into was Dipper "that okay it was an accident,"
"Hey, you're the one that gave me the direction to the mall,"
"Yep, the name Dipper by the way,"
"Gwen so what are you doing here,"
"Oh, I work slash live here,"
"What do you mean you live here?"
"The guy that shows you're around the tour is my great uncle my sister, and I are staying with him for the summer,"
"Hey Dipper do you have any more tape," said Mabel coming up on Dipper and seeing Gwen "and who's your new friend,"
"Gwen meet my sister Mabel,"
Gwen takes a look at Dipper and Mabel were twins almost identical if Mabel didn't have braces and longer hair then Dipper.
"Nice to meet you, Mabel," said Gwen
"You too, so did you Gwen had fun on the Mystery shack tour?" said Mabel
"Um..it was interesting," Gwen said not wanting to tell the truth
"Gwen checks this out," Ben comes up to Gwen in holding a fake stone tablet "do you think Grandpa would buy this for me?"
Gwen looks at the price tag and sees it was 25 dollar "No way he's going to buy this,"
"Oh man," then Ben see the same kid Gwen talk to earlier the day "so talking to your boyfriend again,"
Gwen blushes, "Ben!"
"Wow Dipper didn't realize you got over your crush that quickly," said Mabel smiling from ear to ear
"No we're not dating I j-just help her with some direction when I was getting Stan package," said Dipper who blushes as well
"Guy's I was just joking," said Ben
"Oh," said Mabel who sounded disappointed
"And who this?" said Dipper
"This my cousin Ben, Ben this is Dipper and Mable they are the nephew and niece to the guy that took us on that tour," said Gwen
"Do you guys know that most of the things in that tour are fake, right?"
"Yep," said Dipper
"And sometimes we make them," said Mabel
"So, did you guys stop by the tour?"
"No your uncle would help us out with our Rv trouble if we go on the Mystery Shack tour," said Ben
"That sounds like Stan would do," said Mabel
"He probably calling Soos," said Dipper
"Who Soos?" said Gwen
"He's one of our friends also the Mystery Shack handymen I'm sure he can get your guys Rv fixed in no time,"
