A/N: Yo! This is my first fan fiction, and I think it is OK. But for some reason, betas are not answering my PMs! So, if anyone is willing to beta this story, please PM me. Before the next chapter can come out, I need a beta to review it. Also, I will answer comments and other things here in the future, as well as give credit to people.

Chapter 1: Doritos and Dimensions
"I trust you, Grunkle Stan," said Mabel, and let go of the button, floating up into the air. The timer counted down, and hit zero.
Colors splayed out from the round, white center, dousing the room in light. Then, everything slammed to the ground. A figure appeared in the middle of the whiteness.
"Who's that?" asked Dipper, blinking away stars.
"The author of the journals," said Stan, "My broth… STANFORD?!"
The figure slumped out of the portal, an unconscious, middle-aged man with glasses and a long coat, who, remarkably, had 6 fingers on each hand but otherwise looked like Grunkle Stan. Maniacal laughter filled the bunker, and a distinctive yellow triangle emerged.
"AWW, SO SWEET… AND SO PREDICTABLE! I KNEW YOU WOULD COME THROUGH FOR ME, FEZ!"
"Who are you, and what have you done to my brother?!" Stan yelled, tears streaming down his face.
"THE NAME'S BILL CIPHER! AND AS FOR OL' SIXER HERE, I ONLY KNOCKED HIM OUT COLD TO DISTRACT YOU AND DISPOSE OF THE BIGGEST THREAT!"
Bill pointed at Dipper. Blue energy rippled to life around him, and he was lifted into the air. Mabel leaped and grabbed his foot in an attempt to pull him down. "Uhh, Grunkle Stan?" Dipper began, a quaver in his voice.
"SO LONG, PINE TREE AND SHOOTING STAR!" Bill laughed with glee.
"NO!" screamed Stanly Pines as he watched the two get flung into the portal. Dipper shouted something above the portal's hum has he was thrown, helpless, into the portal, his sister clutched in his arms. It sent Stan staggering back, tripping over his twin and onto the floor. Shocked to his core, he turned it over in his head for the next 6 hours. A terrible, 3 word phrase.
"She trusted you…"
Bill floated there, triumphant."WOW, YOU REALLY MESSED UP, HUH?" No response. "FEZ?" Still nothing. "WELL, I'M WATCHING YOU! REMEMBER, REALITY IS AN ILLUSION, THE UNIVERSE IS A HOLOGRAM…"
Stan didn't hear the rest. His mind started working, only faltering when that Cipher guy disappeared in a flash of light. Stupid theatrical Dorito. But maybe the all-powerful corn chip was right. If reality was an illusion… well, no one knew science like his brother. He began to piece together a plan.
(O0o0O)
Being forced into the portal was like looking up at a torrential rainstorm- but with drops of liquid light in a confusing array of colors, and your vision spinning. Basically, it was about a billion times worse than anything that had ever been done to Dipper before. He clutched Mabel close as the colors continued to fly by. He was still processing what had just happened. He couldn't believe it. He had been just inches from the author of the journals… but Bill had stepped in and completely ruined it. Also, the author was Grunkle Stan's brother? It made no sense. But, somehow, it did. But all of a sudden, Dipper had something else to think about, since their surroundings were changing.
The colors faded, and a beach formed in front of their eyes. And they were hurtling toward it. "Augh!" yelled Dipper and Mabel as they flew to the ground. They landed in a poof of sand, groaning.
Mabel stood up, disoriented. "Where are we, bro?" she asked.
Dipper stood up as well, blinking in the bright sunlight. As his eyes adjusted, he heard clashing and a roaring sound, coming from behind him. He and Mabel turned around, and saw a distant mountain, high over what appeared to be a small town. "Why don't we go over there, where that sound is coming from. I bet we will be able to find someone to help," said Dipper.
"OOH! An ADVENTURE!" cried Mabel, and started running in circles, waving her grappling hook, which got snagged in her sweater. "Darn it!"
"I'll look through the journal. Maybe something can help us," said Dipper, trying to hold in his laughter as Mabel attempted to pull her grapple out of her sweater.
"Oh, ha ha, yes, very funny. THIS IS MY FAVORITE SWEATER!" yelled Mabel as they began the long trek to civilization.
By the time they were close to the mountain, Mabel was sandy and soaked from the beach, and she was wearing her sweater as a hat. Dipper was totally focused on the journal, trying to find anything that could help them get home. Also, he was sweaty from the sun. The metal clashing and roaring had stopped. They walked around the backside of the mountain, and Mabel paused mid-step and looked up in awe.
"Dip, you have got to see this."
It was a giant statue, carved right into the heart of the mountain. It appeared to be a giant woman with several arms, like some sort of Hindu goddess. It had a house nestled right in front.
"What kind of dimension HAS something like this?" Dipper whispered.
"I don't know. Why are we whispering?" Mabel whispered.
Dipper could hear laughter from inside the house. Suddenly, Mabel yelled, "Helloooo? Is anyone there?" Dipper fell down from surprise.
"Mabel," he hissed, "Why?"
"I just wanted to see if anyone was there, bro-bro, wasn't that obvious?" said Mabel, as boy and girl about their age walked outside.
"Hi!" the boy yelled, "I'm Steven!"
"Steven, you don't just yell out your name to strangers!" said the girl admonishingly to the boy, Steven.
"Sorry, Connie!" he said. Connie slapped her hand to her forehead.
"I'm Mabel! This is my twin brother, Dipper!"
Dipper shot her a glare, then looked apologeticly at the two. He would guess that they were friends. "We're lost. Can you help us?" he said.
"Sure!" said Steven, "And the Gems can help you when they get back, too!"
"Gems?" thought Dipper, as a flash of blue light streaked down from the sky into the house, and a female voice said, "Steven! We're home!"
Dipper looked at Mabel. "This should be interesting."
