Thanks for clicking on my story. I hope you enjoy it.

This was originally posted on Archive of Our Own as "Open Your Eyes," a four-show crossover. The other three shows are Uncle Grandpa, Kim Possible, and Detentionaire. Because this site doesn't allow crossovers between more than two shows and I didn't want to post under Cartoon X-Overs, I decided to do something different.

Since in the original story the shows kept to themselves until the end, with chapters alternating between the sets of characters that were followed, I decided to post "Open Your Eyes" as five different fics: one for each show and then a finale posted as simply "Open Your Eyes" under Cartoon X-Overs. The other fics are posted as "Open Your Eyes: Uncle Grandpa", "Open Your Eyes: Kim Possible", and "Open Your Eyes: Detentionaire".

This idea was originally proposed by Dm4487 on Archive of Our Own in the comments for my other work "Total Drama: Cartoon Multiverse." I wrote this as a gift for him.

And now, storytime!

Mystery Shack
Gravity Falls, Oregon
10 months after Weirdmageddon

"MYSTERY SHACK!" Mabel yelled, bursting in through the front door of the tourist trap. She laughed as she took everything in before turning to the man behind the counter.

"SOOS!" Mabel yelled, and ran over to wrap him in a hug.

"Hey hey, Mabel!" Soos said happily, hugging her back. "Dude!" he exclaimed as Dipper walked through the door, much calmer than his sister.

"Hey, Soos, good to see you again," Dipper said. "Uh, where's Wendy?" he asked, pretending it was an afterthought.

"Oh, she's on a reality show. In Canada!" Soos said.

"It's so good to be back!" Mabel exclaimed. "Where's Grunkle Stan and Grunkle Ford? I have so much to tell them, and I made them special sweaters!"

"Oh, they've been gone for about a week now," Soos said. "Something about a 'dimensional anomaly.' I dunno, they just left me in charge of the Mystery Shack and ran off."

Dipper and Mabel's faces fell.

"Hey, c'mon now, I'm sure they'll be back to see you! They love you guys!" Soos said. "Tell you what, let's go to Greasy's. Lunch is on me."

Greasy's Diner
Gravity Falls, Oregon

Soos parked his truck outside the diner. As he pulled the keys out of the ignition, the twins opened the doors and hopped out. He followed the twins into the diner, which was mostly deserted at two in the afternoon; the only other customers were Toby Determined and Tad Strange.

"Oh, the twins are back!" Lazy Susan said. "Everybody, the twins are back!"

"Welcome back to Gravity Falls," Tad said. "It's nice to see you two again."

"Toby Determined, reporter for the Gravity Falls Gossiper," Toby said, coming over to them. "Is it true you two are in town to solve more supernatural mysteries?"

Dipper looked at the turkey baster being held out to him. "You do realize that's not a microphone, right?" he said.

"I know," Toby said pitifully.

"Well, to answer your question, Toby," Mabel said cheerfully, "yes, we are here to solve mysteries, if mysteries need solving, and to spread joy and glitter. So much glitter!"

"Um, Mabel?" Dipper said.

"Not now, Dipper!" Mabel said. "I'm telling Toby what we're going to do this summer!"

"But we don't even know what we're going to do!" Dipper hissed. "And besides, Soos got us a booth."

Mabel looked over to Soos, who was indeed sitting in a booth. Soos waved to her.

"Fine," Mabel said. "Bye, Toby, we're gonna eat lunch now!"

Mabel and Dipper walked over to Soos and sat down across from him. They picked up their menus. Dipper smiled as he scanned his.

"Same old menu," he muttered to himself. "I guess some things don't really change."

"So what'll it be?" a familiar voice asked.

Dipper looked up and froze. His sister did not.

"Pacifica!" she said happily, quickly climbing over Dipper and out of the booth. She pulled Pacifica into a tight hug. "How have you been! It's so nice to see you again!"

"Can't...breathe..." Pacifica choked out.

"Oh, I'm so glad you're here! Wait, why are you here?" Mabel asked. She released Pacifica. Pacifica put her hands on her knees and panted for breath.

"Mabel, that's a bit personal..." Dipper warned.

"Oh, c'mon, why wouldn't Pacifica be glad to see us?" Mabel asked. "I thought we were becoming friends."

"During the Never-Mind-All-That?" Soos suggested.

"Yeah!" Mabel said. "Of course she's glad to see us!"

Pacifica straightened herself up.

"So, what'll it be?" she asked them.

"Pacifica!" Mabel said, shocked. "Why are you taking our order? Do you work here?"

Pacifica scowled. "Are you going to order, or what?"

"Pancakes," Dipper said.

"Double cheeseburger with mayo," Soos said. "Oh! And fries."

"But Pacifica, why do you work here?" Mabel asked.

Pacifica's scowl deepened.

"Mabel, I think this is a touchy subject!" Dipper said quietly. Mabel's eyes widened as she caught on.

"You want to know?" Pacifica asked bitterly.

"Um, yes?" Mabel said nervously.

"After my dad invested all his money in weirdness bonds, we ended up broke. We sold the mansion, ended up in a house in town, and because he's used to the finer things in life, we burned through the rest of the money in months. Now Mom's an Avon lady, Dad's a temp worker doing data entry, and I have to find work where I can get it. So are you going to order anything?"

"...I'll just have the soup," Mabel said quietly.

Pacifica jotted her order down. "Your orders will be up in a bit," she said, and walked away from the booth. Mabel stared at the table sadly.

"Aw, come on dude, it's not that bad," Soos said. "Remember how she used to pick on you?"

Mabel sighed. "It's just sad, that's all."

Suddenly, the door to the diner burst open, and Fiddleford McGucket burst in with a laptop in his hands. He ran up to Mabel, Dipper, and Soos.

"Help!" he yelled at them. "Strange visitors from another dimension, I done seen 'em! On this here computer! They wants to talk to you!"

McGucket thrust the laptop at them. A strange-looking old man stared out at them.

"Oh, hey!" he said happily. "I've been looking for you!"

Dipper and Mabel looked around warily. The man on the screen laughed.

"Don't worry! Not like that. Well, kind of like that. But I've been watching you, and–"

"Bill," Dipper breathed. Mabel nodded.

"No! No!" the man hastily backtracked. "My name's not Bill at all! My name is–"

"Don't say it!" a high-pitched voice said loudly.

"Oh, right," the man said. "Thanks–"

"Don't tell them my name!" the high-pitched voice interjected.

"Fine," the old man said. "So, you're probably wondering why I called you."

"Because you're from another dimension!" Fiddleford said frantically. "I may be an old coot, but I recognize an extradimensional being when I see one!"

"No!" the old man denied. "No, I called because I kidnapped your grunkles."

Everyone gasped.

"Give us back our Grunkles!" Mabel yelled.

"Okay, sure! How can I say no?" the man on the laptop screen said cheerfully.

"No!" the high-pitched voice said. "We have to do this, remember?"

"Oh yeah, right," the old man said.

"Wait, who said that?" Dipper asked.

"That was–" the man started to say.

"Don't tell them!" the voice exclaimed.

"No, tell us," Soos said affably. "We won't tell anyone else."

"No!" the high-pitched voice said. "Look, just do what we say, and nobody gets hurt."

"And if we don't?" Mabel suggested.

"Nobody gets hurt!" the man proclaimed happily. "Well, probably."

"That isn't much comfort," Dipper said.

"Oh, sorry," the old man said. "Would it help if I told you they're okay?"

"Not really," Soos said. "Like, why should we trust you?"

"You don't trust me?" the man asked. Tears welled up in his eyes. "But, but I'm–"

"But, you're a kidnapper," his high-pitched assistant pointed out. "Now give them their instructions!"

"How do you know we'll do whatever you say?" Mabel asked.

"Because you love your grunkles," the high-pitched voice said.

"Fine. We'll do it," Dipper said. "But only if you promise us we'll get our Grunkles back."

"Sure, no problem," the old man said. He tapped his chin thoughtfully. "But there have to be four of you."

Suddenly, a voice called to him from offscreen.

"Hold on, gotta talk to somebody else. Be right back!" the man said.

The camera continued to broadcast as the man left. He came back about a minute later.

"Okay, four of you and a pet. If you have a pet," the man said.

"Waddles!" Mabel exclaimed.

"Yeah sure whatever kid," the old man said.

"Where will we get a fourth person?" Dipper mused.

"Cloning!" Soos suggested excitedly.

"Yeah, no, already tried that," Dipper said. He shivered.

"Listen, I'll call you back in an hour with details. You can get your team together, and then start the adventure!" the old man proclaimed happily.

Greasy's Diner
Gravity Falls, Oregon

Dipper picked at his pancakes. He had barely eaten half of his first one, and Mabel hadn't even touched her soup. Soos had finished his cheeseburger several minutes ago and was now staring at the two thirteen-year-olds uncomfortably.

"So, like, are you going to finish that?" he finally asked.

Dipper slid his plate over to Soos, rested his head on his arm, and traced designs on the dirty table with his finger.

"It just doesn't make sense," he said to himself. "How did Ford and Stan get kidnapped? And why would we be enlisted to find them? None of this adds up!"

"I don't think that's important, Dipper," Mabel said sadly. "I think we have to find them."

"But where do we even start!" Dipper said loudly. "We've got no leads! No clues! No idea what we're doing! Nowhere to start!"

"You could start by finding a fourth member of the team," Soos suggested. "I mean, that's what the guy said to do, right?"

Dipper went back to running his finger over the table. Mabel stared at her soup sadly. Soos chowed down on Dipper's pancakes quietly.

"You want the check?"

The trio looked up. Pacifica was waiting by the table impatiently.

Dipper grinned as he got an idea.

"Hey, Pacifica, wanna go on an adventure?"
