Mabel stood proudly on a log in the cheery woods as the warm sunlight flooded her face. She had a rather large backpack sitting on her shoulders.

"Ah! Finally, a family camping trip!" she exclaimed. "I'm going to name every squirrel and eat every dangerous kind of oak!"

"We're not camping, Mabel. This is a scientific expedition!" Ford said from behind her, with Stan, Dipper, and (y/n) in tow.

He then held up the blaster he was carrying, which was filled with pink alien adhesive.

"We're searching for leftover multidimensional rips from Weirdmageddon to patch up with alien adhesive" he explained momentously. "So keep an eye out for anything that seems...love crafty."

Dipper turned towards his uncle.

"Great Uncle Ford, what was it like in the Multiverse anyway?"

"Confusing. One minute, you're breathing air, the next you're breathing fingers. Think you found a sandwich? It's a planet. You just ate a planet!" Ford responded with a rather grave tone, as if that had actually happened to him before.

Dipper took out a pad of paper and started to scribble down notes.

"Multiverse tips...don't...eat...planets...got it."

"Just be careful where you point that nerd gun, brainiac" Stan scolded his brother, shoving the gun's aim away from Dipper. "We need these kids back on the bus in three days, and I want 'em going home in one piece."

Ford sighed.

"Stanley, under your watch, the triplets fell into a bottomless pit" he pointed out. "I'm not sure you should be giving caretaker advice."

Stan's eyes widened with outrage.

"What? I'm the best caretaker ever!" he exclaimed. "I've taught these kids valuable life lessons. Like how to hotwire cop cars!"

"It's true!" (y/n) piped in. "I once hijacked a cop car, went eighty four miles over the speed limit, and then crashed the vehicle right into the police station!"

Ford raised an eyebrow, then looked back at his brother.

"What's Dipper's real name?"

Stan's eyes widened in alarm for a brief moment, before he crossed his arms over his chest knowingly.

"Diptholomew! I don't know! Bottom line, I could caretaker circles around you!"

Behind them, Mabel held up a bright green leaf.

"Hey, Grunkle Stan, this oak makes my face feel funny!"

"Not now, sweetie" Stan shouted back, before turning back towards his brother.

Meanwhile, (y/n) tapped Mabel on the shoulder.

"Hey, Mabel, have you seen my mind-reading device?" she asked. "The one I lent you three weeks ago?"

Mabel turned towards her sister with a huge grin plastered across her face.

"What? That old thing? It was old and rusty, so I had it shipped up to Silicon Valley to be fixer'd up!"

(y/n) put her hands on her hips narrowed her eyes.

"Mabel, what did you really do with it?"

Mabel laughed nervously, and ran her hand up and down her other arm.

"Well, you know how you start off in one place and then end up in another, and then forget what you were originally doing, so you have to go back to the first place..."

"Mabel."

"I lost it in the woods."

(y/n)'s eyes widened in outrage.

"You what?!?!"

Mabel shrugged.

"I was gonna give it back, I swear!" she insisted. "But then life happens, you know? One moment you're trying to read a hot centaur's mind, and then the next you're trying to catch a butterfly that changes colors based on its mood!"

"Wait, hold up. So you're telling me that you lost my precious mind-reading device chasing a freakin' butterfly through the woods?"

"It was a color-changing butterfly!" Mabel exclaimed, pulling a jar out of her backpack with the multi-colored butterfly flapping inside. "You can have it if you want."

(y/n) groaned in vexation, and walked ahead of her sister before she could punch her.

"Just pay me back later" she growled. "And I reserve the right to include interest!"

Mabel simply shrugged as if nothing had happened, glad to get out of that situation before walking up to her more amiable brother.

"Psst--Hey, Dipper! Guess who I brought along?" she whispered, opening her massive backpack. Out popped none other than Waddles, who oinked happily.

Dipper, however, looked at his sister with disapproval.

"Mabel, didn't you hear Ford?" he said. "This is a dangerous mission!"

"Aw, c'mon! This girl needs some one-on-one pig time before Summer's over!" she insisted, as she patted Waddles on the head.

"Mabel, I know you don't want to hear this, but don't you think you're being a pinch self-centered?" Dipper asked reluctantly.

"What? I'm the least self-centered person!" Mabel said, before pointing towards (y/n) up ahead.

"If you want to talk about self-centered, (y/n)'s just up there sulking about her missing do-hickey" she whispered.

"That you lost!" (y/n) shrieked, slamming her fist into a nearby tree ferociously. She stormed away, leaving a vivid imprint of her fist in the tree's trunk.

Dipper stared at the trunk with wide, alarmed eyes before turning back towards Mabel, who didn't seem to be the least bit threatened. Instead, she shrugged nonchalantly.

"She'll get over it. This isn't nearly as bad as the time I accidentally tie dyed her t-shirt that she got signed by Steve Jobs" Mabel insisted. "Besides, it's scientifically proven that every adventure is better with a pig. Right, Waddles?"
She looked down at her backpack, only to find that it was now empty.

"Waddles?!"

"I watch these kids like a hawk!" Stan argued with his brother, as Mabel was chasing her pig in the background right towards an open wormhole. "Nothing gets past me!"

Mabel finally caught Waddles, and she held him up triumphantly, just a few inches in front of the wormhole. However, she didn't even seem to notice.

"Found my pig!" she announced.

Everyone looked at her with wide, distressed eyes.

"Mabel!" screamed Stan.

"A wormhole!" cried Dipper.

"Stay back!" Ford yelled.

"Giant finger!" shouted (y/n).

But Mabel was too invested in kissing Waddles to notice the massive finger coming out of the portal behind her, just a few feet above her.

"Who's a little guy? You are!"

The finger suddenly came down right on top of her, pinning her to the ground.

Mabel dropped Waddles, who quickly scurried away.

"Aaahhh! A thing! I'm being grabbed by a thing!" she cried.

"Mabel!" Stan screamed, as she was being dragged into the wormhole by the finger.

(y/n) immediately bolted forward and seized Mabel's hands, pulling back with all her strength.

"Give me back my sister!" she screamed with rage, and for a brief moment, the finger actually froze. But it didn't look like she could keep it up for long, for her feet were slowly starting to slide towards the wormhole as well.

Dipper turned towards their other uncle.

"Ford, do something!" he yelled.

Ford was already tying a wire attached to his belt around a nearby tree.

"Good thing I wore my infinity belt!" he yelled. "Stanley, grab ahold of me!"

Mabel was just two inches away from the wormhole, and (y/n)'s fingers were starting to slip.

"Bad things are happening right now, guys!" she shouted terrifiedly.

Ford turned towards his niece.

"Whatever you do, don't let..."

Mabel's fingers slipped from (y/n)'s grasp, and she screamed helplessly as she was pulled into the wormhole by the giant finger.

"...go!"

"MABEL, NO!!!" screamed Stan.

Inside the wormhole, Mabel found herself floating in Dimension D: The Nightmare Realm, right towards the creature. It was a disturbing monster, with seven massive fingers and a mouth right in the center.

It screeched ferociously at her.

"This can't be happening! I'm too adorable to die!" Mabel screamed. "Flail, Mabel, flail!"

She did just that, and the giant hand creature grabbed at thin air where she had been just a few seconds ago.

"Ha! Missed me!" she cheered triumphantly, but unfortunately her victory was short lived, for she had flailed right towards a glowing white portal.

"AAAAAAAAAAHHHHHHH!"

Mabel started falling through multiple dimensions, including a mario kart version of the Mystery Shack, a dimension where the remains of Bill's monster army were, and another dimension where everyone had been turned into fish.

"Where is this taking me?" Mabel cried, falling through dimensions petrifyingly.

It was then when she noticed something shiny falling just a few feet below her.

Similarly to how she would do so in a pool, she started swimming down towards the object, and when she was close enough, snatched it out of the air.

In the palm of her hands was none other than (y/n)'s mind-reading device, a flat metal circle that was about the size of a compass, with a speaker on the front, an activation button on the back, and an antenna on the side.

"Sweet! (y/n)'s mind-reading device! So this is where you've been hiding, you little devil!" Mabel said to the device, shoving it into her skirt pocket as she fell to the end of the portal...

...With a wham, Mabel finally landed flat on her face at her final destination. She sat up and looked around to find the last thing that she expected to see.

The entire place was filled with different versions of herself, including a dinosaur, a hand, a goose, a mario kart princess, a (y/n)bel, and a Mabipper to name a few.

And there were thousands more still.

"What the hey-hey?! Where am I?" Mabel exclaimed, looking around at all the weird versions of herself.

She picked herself up off the ground, and started wandering around the place.

"Razzle my dazzle, it's a Mabel Bonanza! There's every possible version of me!" she said aloud. "Table Mabel, molecularly unstable Mabel..."

She then walked up to a normal-looking Mabel, who was turned with her back facing her.

"And, hey, you look just like me!"

However, the Mabel turned around, revealing a giant set of teeth where her chest should have been.

"Whoa, girl! You are fierce, and I love it!" Mabel chimed.

Just then, a tidy Mabel with a clipboard and a flower pen walked up to her.

"Hello, there! You must be new here. Which Mabel are you?"

Mabel put a hand on her chest in a confident manner.

"Uh, the best Mabel, obviously" she said, as she started laughing.

The tidy Mabel started writing on her clipboard.

"Slightly...arrogant...Mabel...Got it."

"What! I'm not arrogant! I'm lovable!" Mabel protested. "Here's a joke—How many Mabels does it take to screw in a lightbulb?"

A Mabel wearing a sports jacket glared at her.

"That is extremely offensive to Lightbulb Mabel!" she scolded, with one comforting hand on a version of Mabel whose body was a giant lightbulb.

Lightbulb Mabel sniffed sadly.

"Oh my gosh! I am so sorry, Lightbulb Mabel!" Mabel quickly apologized. "I just don't understand. What is this place?"

A Mabel wearing glasses and a graduation hat walked up to her.

"Let me explain. When similar beings get lost in the Multiverse, they tend to be drawn to each other, clustering together like potato chip crumbs at the bottom of the bag" she explained, holding up a watch that projected a holographic image of two Mabels to demonstrate. "Welcome to Dimension Mab-3l, where lost Mabels stick together!"

"Thanks, Explainbel! Super helpful! But like... how do we get out of here?"

Explainbel's expression dropped.

"Unfortunately, we are trapped here forever" she said, gesturing towards a Mabel who was sitting next to an unfinished pod. "The smartest Mabel here, Brainbel, tried to invent a dimensional escape pod, but she's been too busy working on her sticker collection to finish it."

Mabel's arms flew out in shock.

"What?! I mean, I love stickers as much as the next Mabel, but what about home?" she exclaimed. "I bet if we worked together, we could get that puppy up and running!"

Explainbel's eyes widened.

"Sorry. I totally lost my train of thought when you said puppy."

That one word had caught the attention of a couple of other Mabels.

"Who said, puppy?" asked a fish version of Mabel.

"Puppy? Where?" said another Mabel with a top hat.

T-rex Mabel roared.

"I WANT TO PET A PUPPYYY!!!"

All Mabel could do was glare with irritation at the other Mabels.

Meanwhile, Ford and Stan were floating through the Multiverse, each with wire tied around his waist that was attached to their own dimension through the wormhole they'd entered.

"Mabel! Mabel, Sweetie! If you come out, I've got some candy for you!" Stan called out.

"And I'll give you some delicious vitamin supplements! Fourteen kinds of zinc!" Ford chimed in.

Stan looked over at his brother with a raised eyebrow.

"You don't know anything about Mabel, do you?"

"Of course I do! I scanned her entire molecular structure the day I came here" Ford argued. "Guess how many enzymes she has? The answer might surprise you!"

Stan glared at him.

"Sixer, I swear, if I lose my niece..."

Ford put a comforting arm around his brother.

"Stanley, trust me, we'll find Mabel. I know the Multiverse."

Holding onto Ford, Stan stuck his head into one of the weirdness bubbles.

"Mabel?" he called, only for a green octopus creature with wings to cling to his head when he emerged.

"Ph'nhlui mglw'nafh!" the creature cried.

"Keep looking" said Stan.

Mabel was now pleading with Brainbel, who was busy writing in her sticker book.

"Brainbel, please! I have to go back home! I just escaped one Weirdmageddon, and I don't need another one!" Mabel begged, only for Brainbel to ignore her and hold up a hand carelessly.

A Mabel with a backwards hat carrying a red party cup walked up to Mabel and put a hand on her arm.

"Chillax! She'll get around to it whenevs!" she reassured. "Wanna hack some sack?"

Mabel glared at her.

"I do not appreciate your laid-back attitude, Mabro!" she shouted irritably.

Giving up entirely on trying to convince the other Mabels to help her, Mabel sat down on a nearby bench in defeat.

"These Mabels are driving me cray-bel! The Stans can't get here soon enough!" she said aloud in frustration.

That was when a normal-looking Mabel walked up to her, a look of relief flooding her features.

"Finally, a normal one!" the new Mabel said.

"Oh, hey. Which Mabel are you?" Mabel asked.

"They haven't given me a name yet, thank goodness" the new Mabel replied. "I don't know why they think everyone needs one."

Mabel grinned.

"Sounds like you're the anti-label Mabel."

The new Mabel threw her arms out in frustration.

"No! I'm just a regular Mabel like you!" she exclaimed. "Listen, there's a way out of here, but I don't trust these other wack-jobs to work together with me. Some of these other Mabels seriously creep me out!"

She gestured towards a particularly disturbing version of Mabel, who had Stan's head sitting on her shoulders.

"Heyyy! Stanbel is single and ready to mingle!"

Both of the Mabels shuddered in horror at the sight of Stanbel.

The new Mabel put her hand on Mabel's shoulder.

"You've got friends searching for you, right? We need to send a signal to them! Military expert Mabel has a flare gun, but she says it's for emergency raves only" she explained. "You distract her, I'll steal it, and together we can get back to our home dimensions!"

Mabel pointed at her knowingly.

"I like the way you think Mabel!" she said.

"That's 'cause I think like you, Mabel!" the other Mabel replied.

"Eeeeehhhhhh!"

The Stan twins were now utterly lost in the Multiverse. Ford was sending out a red beacon on his watch.

"This distress beacon will summon either an interdimensional good samaritan or an unimaginable beast that feeds on fear."

Stan raised a triumphant fist.

"I like those odds!" he proclaimed.

HONK! HONK!

Stan and Ford turned towards the source of the honking to find a tan flying ship pulling over.

The driver was an alien made out of pink slime, wearing an infinity cap and chewing on a stick of wheat.

"Well entangle my particles, what are you apostrophe backslashers doin' out in the middle of the multi-sticks?" he asked with a southern accent.

Stan held up a photograph of Mabel hugging a stuffed penguin.

"Looking for one of the best grandnieces in the Multiverse!" he said. "Ya seen her?"

"Maybe I have, but I'd never let a known criminal onto my truck" the driver said, his voice dropping to a more serious tone.

Stan looked at him with disbelief.

"My criminal record made it into space?!" he said. "I gotta admit, I'm kinda impressed with myself."

The driver pointed at Ford.

"I was talking about him!" he exclaimed. "Your wanted posters are everywhere from here to Lottocron 9!"

Stan couldn't help but laugh as he faced his brother.

"Hahahaha! You serious?! Mr. Goody-nerd-shoes is a criminal out here?"

Ford shrugged sheepishly.

"Look, I might have stolen a few...hundred...parts to build my quantum destabilizer" he tried to explain. "But it was all in the name of science!"

Stan eagerly held up a pair of handcuffs.

"How's about we leave him cuffed in the back while I sit in the front?" he offered the driver.

The driver agreed.

"Deal."

Ford looked at his brother with outrage.

"What?!"

A few minutes later, Ford was sitting in the back of the truck with his hands cuffed together, while Stan was in the passenger seat telling jokes to the driver.

"So I says to him, Dark matter? More like, dork matter!" Stan was saying.

The driver laughed boisterously.

"Hahaha! Brilliant!"

Ford glared from the back.

"I hate this."

Military Mabel was sharing her story with the original Mabel.

"So there I was, surrounded by bodies. I had won the war, but I had lost my soul, and I was all like...whaaaaat?"

Mabel nodded sympathetically.

"Oh, totally. Totally. Been there."

She saw the other Mabel, flare gun in hand as she was starting to make her getaway.

It was her cue to leave.

"Ooh, gotta go. Mabel biz" said Mabel.

Military Mabel saluted her respectfully.

"Sir, yes sir!" she proclaimed.

When they were a distance away, the two Mabels both held up the flare gun towards the sky.

"I hope this works" they both said simultaneously, before looking back at each other with identical smirks on their faces.

"Jinx! Haha! You and me, what a pair we are!" said original Mabel, as they fired the signal into the air.

BOOM!!

Just a couple galaxies away, Stan immediately saw the bright pink Mabel signal in the sky, winking with the words, 'Hey Boyz' above her head.

"There she is!" Stan proclaimed, pointing at the Mabel signal. "Quick! Head towards that exploding child!"

Back in Dimension Mab-3l, both of the Mabels were cheering triumphantly at their successful signal.

"We did it!" said the other Mabel.

"Haha! Mabels for the win!" exclaimed the original Mabel, wrapping her arms around the other Mabel in a tight embrace.
