Alright so this is quite famous, the Mystery Trio AU. Basically, in this AU, Stanley, Stanford, and Fiddleford created the portal. And, well let's just say nothing ever goes wrong with the original Mystery Twins mixed with the now Mystery Twins.
☆~☆~☆~☆~☆~☆~☆~☆~☆~☆
Mabel, Dipper, and Bill arrived in front of an eerie and old building. The twins studied the place, full of curiosity.
"Is it just me or is it familiar?" Dipper asked
"It's familiar." Mabel nodded, "Although I can't quite put my finger on it."
"What about you Bill? Does the place seem familiar to you?" Dipper interrogated
"It does. And it should to you too." Bill responded, "I can't believe you two haven't noticed it yet!"
"Noticed what yet?" Mabel raised a brow
Bill snapped his fingers and a light silhouette of the Mystery Shack formed in front of them, outlining the house in every way possible.
"It's the Shack!" Mabel cheered, "Yay! We're home!"
"Um, not quite Mabel." Dipper stated, "I don't think that this is our Shack. I don't even think that we're born in this time."
"You're on a roll today, Pine Tree. Alright, here's the deal, I'll let you go out of the bubble this one time in exchange, you will only stay inside the Shack." Bill stated, "Welcome one and all to dimension 20 18 9 15!"
"So, wait, no catch?" Dipper asked, putting a hand to his chin
"You kids haven't learned anything, have you? The only catch here is that you go out before I change my mind." Bill responded
Mabel and Dipper hurried to go inside the Shack. The kids looked around. The Shack was not filled with the all too natural charm and mysterious aura it had when they were around but it was mysterious in its own way. There were several books on tables. Most of them were opened up at certain pages, as if the reader had stopped reading for a while. Paper and cans of Pitt Cola were thrown around on the ground.
"I don't get it. Where are the snowglobes and attractions?" Mabel asked
Dipper was all too busy reading the words on the books that he did not notice somebody creeping up on him. Mabel, on the other hand, was too caught up with everything going on in the dimension.
"Who are you two?"
Mabel and Dipper jumped in fright and looked over at the source of the sound. Upon discovering the person who spoke, both shared wide grins.
"Grunkle Stan!" They yelled loudly
"Grunkle what?" Stan asked
"Grunkle Stan you're here, and oh wait, I don't think he knows who we are yet." Dipper stated
"Oh I know you two." Stan said
"Really?" Mabel smiled
"Yes." Stan nodded, "You two are crooks who want to steal my brother's works! Get out of the house before I throw you out!"
"No please, Grunkle Stan, we can't go out!" Mabel pleaded, "We'll go out of existence if we go out."
"I don't care about your lies, kid, that doesn't even sound real, anyway." Stan responded, pushing them
Mabel and Dipper struggled not to get pushed away.
"Grunkle Stan, you're, uh," Dipper looked around, "will you believe us if we tell you that Bill is part of the reason we're here?"
Stan's eyes went wide. "Bill? Why do you know him?"
"He took us from our dimension and went dimension-hopping." Mabel responded, "I think he was trying to find company more than doing us a favor."
"Hey! Stop talking behind my back, Shooting Star!" Bill appeared from a corner suddenly, "So, Stan Pines, I see you've been busy enough to not find time to take a bath. Pine Tree, this is what you'll look like if you keep up with your no bathing streak."
"Look here, you dorito. I know that you're working with my brother but you have no right to tell me that!" Stan argued, "What are you even doing here?"
"I'm making sure these children have fun." Bill answered
"I'm kind of uneasy with that thought. Your 'fun' is kind of not the fun we have." Stan commented, "They're sick and twisted. Like you!"
Bill stared at Stan, "Is that supposed to insult me?"
"Oh don't bother." Stan grumbled, "Now if you don't mind, we have a visitor and I would like to prank him."
"Did you just say that you're pranking a visitor?" Mabel asked, a grin forming on her lips
"Exactly." Stan nodded, "He's this big cuckoo head that's going to help us build the portal this guy right here ordered."
Mabel and Dipper looked over at Bill.
"What are your plans again?" Dipper asked
"Nothing you shouldn't be informed of yet." Bill answered, "Now go help the old man here with his plans."
After about an hour of Stan's elaborate planning, Dipper's reasoning, and Mabel's creativity, they had formed the perfect prank for their visitor. The moment the door opens and the visitor enters, the bell on the door will ring, signifying the presence of a person. A fog machine they found in the attic will be opened and the fog will spread throughout the floor. Once it does, the door will close shut and there was absolutely no way the person was going to get out of the house. Stan would speak some spooky things, in his point of view, about the world's end and the destruction of everything that is known. The books will then levitate, with the help of Bill, and they will hold up the act until Stan could no longer stifle his laughter.
"Stan? Is Fiddleford here yet?" A person asked from somewhere in the house
Bill put the twins in a protective bubble again, "Time to go!"
"No wait, what about the prank?" Mabel asked
"You can't know this yet! You're on your own, Stan!" Bill announced then snapped his fingers, bringing them to the next dimension
Mabel pouted and glared at him.
"What?" Bill asked, "I'm keeping you away from information that you shouldn't know just yet. Wait for a few more weeks then you'll know who the guy is."
