It was a beautiful day in Gravity Falls. The sun was shining, the birds were singing, and everyone could almost forget the full day of thunderstorms that had preceded it. Everyone, that is, except the residents of the Mystery Shack. Thanks to the heavy rains and Stan Pines' insistence that dirt was just as good a surface to park on as anything else, the shack was currently surrounded by a mud pit deep enough to fully submerge Waddles. After the poor pig had nearly drowned that morning, it had been concluded that the shack would have to close for the day (or risk lawsuits from tourists getting their vehicles stuck). This left the younger Pines twins with their current predicament, how to spend the day.

"Okay," Dipper said as he looked over their list of ideas. "Grunkle Ford's busy with whatever he does in the basement, so we can't ask for any cool stories about other dimensions. Grunkle Stan's repairing the taxidermy attractions, so we can't ask for a ride into town. And everyone else is dealing with the fallout of yesterday's storm at their own homes, so they're busy."

Mabel slumped on the kitchen table across from him. "Why is it the one day we could use a wacky adventure, nothing's happening?" She threw her head back and yelled at the ceiling. "Come on Gravity Falls, we know you can do better!"

As if on cue, a knock sounded from the front door.

"I'll get it!" Dipper and Mabel shouted in unison as they sprinted across the living room, Dipper just barely beating Mabel to the door. He threw the door open to reveal a very familiar blonde dressed in a trenchcoat and sunglasses.

Mabel snorted. "Talk about deja vu."

Dipper sighed. "What is it this time Pacifica?"

Pacifica fidgeted with her sunglasses. "So, you remember how you helped me with that lumberjack ghost?"

Dipper leaned against the doorframe. "Let me guess, there's another one."

Pacifica nodded. "Three actually."

"Is this going to be a regular thing for you?"

Pacifica shrugged. "Given how many people my family's screwed over, maybe."

"Will we get to ride in the limo?" Mabel interjected.

Pacifica eyed the brunette warily. "If I say yes, will you help?"

"Absolutely!" Mabel responded before Dipper had a chance to open his mouth.

"Mabel!" Dipper hissed before pulling her away from the door. "Did you seriously just sign us up for a ghost hunt at the cost of a limo ride?"

Mabel threw her hands up in exasperation. "It's not like we've got anything else to do!"

Dipper opened his mouth to retort, then paused as Mabel's words sunk in. "Fair point."

Mabel fist-pumped. "Alright! Ghost hunt two: electric boogaloo, here we come!"

Once the three were situated in the limo (and Mabel had finished oohing over its fanciness) Dipper pulled a stack of papers from his vest.

"Okay, so based on the fact that there seems to be a group of spirits and not a singular ghost, I think I know what category we're dealing with." He turned the pages around, revealing them to be photocopies of Journal 3's contents. "Catagory two: Pranksters. According to Grunkle Ford's research, these ghosts are known to appear in groups of two or three. They're not very powerful, but they are natural troublemakers, so this might be a bit tricky."

Mabel lightly punched his shoulder. "Come on Dip-Dop, I'm sure they can't be all bad, maybe they just want to have fun!"

Pacifica gave Mabel a deadpan stare. "I woke up with 'Possess Me' written on my forehead."

Mabel shrugged. "Must be ghost humor."

Dipper shivered. "Anything that considers possession a joke isn't fun in my book."

Mabel winced as memories of yellow eyes and water towers resurfaced. "You know I didn't mean it like that. Just, can we try talking to them first? All the ghosts we've met have had a reason for haunting people."

Dipper fidgeted with the pages a moment before nodding. "Alright."

"Glad we've settled that," Pacifica said. "Because we're here."

Northwest Manor was every bit as ostentatious as the twins remembered from their previous visit, though small signs of ghostly interference managed to poke through. Chunks of the carefully manicured hedges were broken off, faint streaks of unidentified fluid colored the windows, and the butler who greeted them at the door seemed a bit less composed than usual.

Dipper's eyes narrowed as he examined the foyer. "So where have the ghosts been most active?"

Pacifica waved her hand in a general indication of the manor. "Pretty much everywhere, though easily stained and valuable items tend to draw their attention." At her words, a crashing sound echoed from the depths of the mansion. "I'm really glad my parents are out."

"Have they mentioned wanting anything?"

"I don't think so."

"Have-"

"You know," a third voice interrupted. "If you have questions, it'd be more polite to ask us directly."

The trio turned to the staircase to see the ghosts in question. All three were female, about the same height and apparent age, and wearing the same halter top gown with gloves, though with different colors.

Mabel snickered. "They look like Pacifica's ghosts of makeovers past."

They did indeed share a remarkable resemblance to Pacifica, particularly the one furthest to the left. She was decked head to toe in red, including hearts painted on her cheeks, which combined with her wavy blonde hair made her seem like a Valentine's Day caricature of the youngest Northwest. The other two had less of a resemblance. The ghost who had spoken was the most disheveled of the three, with mud spattering her green dress, twigs tangled in her red hair, and a tooth missing from her smile. And the last looked like an unholy cross between Robbie's emo style and Pacifica's expensive taste shoved into a blue gown to match her counterparts.

Dipper pulled himself from his observations and stepped forward. "So ghosts, what do you want? Why are you haunting this place?"

The blue ghost rolled her eyes, "Because Blondie summoned us, duh."

"Excuse me?" Pacifica shouted indignantly. "I did no such thing!"

The red ghost chuckled, pulling a hand mirror out of seemingly nowhere to fix her hair. "Must have been another rebellious Northwest then. That, or your parents' favorite rug stained itself."

Pacifica's eyes widened. "So when I got mud on that carpet-"

"You woke us!" The green ghost finished with a gap-toothed smile. "I never could resist a fellow troublemaker, and my sisters were down for some mischief. Now let's play tag, you're it!" The ghost tapped Pacifica's arm before speeding down a hallway.

Back at the stairwell, the other two ghosts took off down their own hallways.

Dipper ran in the red ghost's direction. "Split up and try to herd them back here! I only have one vial of holy water!"

"You got it broseph!" Mabel called as she chased after the blue ghost.

Pacifica sighed as she trudged after the green ghost. "Why did I get the messy one?"

"Hey!" Dipper yelled as he sprinted around the corner after the red-garbed ghost. "StOp!"His voice cracked, causing the boy to flush.

Ahead of him, the ghost had stopped, regarding him with a scrutinizing look. "I've never heard a pitch that high from a male." She floated closer. "You must be a particularly homely girl."

Dipper's mouth dropped open as his brain attempted to formulate a response. "I-I'm not-"

"Oh I'm afraid you are quite plain, and I won't stand for it," The ghost stated matter-of-factly as she grabbed his wrist. "If I'm going to be chased by a girl, she's going to look fabulous!" She dragged him into a room with a large walk-in closet (Pacifica's?). "Now, let's find you a dress."

The ghost's first order of business was to stick Dipper in a get-up that seemed remarkably similar to Pacifica's ensemble from the last ghost incident, heels and all. And as embarrassing as that was, the far more pressing issue was its additional function as a restraint. The tight violet dress restricted his movements, the heels made it impossible to walk on the thick carpet and the boa… the boa just itched a lot.

The red ghost grasped him by the shoulders and sat him in front of the room's vanity, pulling a set of brown extensions out of seemingly nowhere.

"Now let's get the head to match the outfit," she chirped as the various brushes on the vanity floated into the air. "First things first, let's get a base coat of foundation on you." As she spoke a bottle of peachy-colored liquid and a cone-shaped chunk of foam moved to hover in front of his face. The liquid was smeared across his skin with what looked like a lip-gloss wand and then rubbed in more thoroughly with the foam.

The ghost tilted her head in consideration as she used her hand to tilt Dipper's face. "Hmm, seems you might have some cheekbones buried under that baby fat. Let's see if a little bronzer helps bring them out!"

This time a powder was dusted along the sides of his face with a soft brush that sort of tickled.

"Great, you've put a little makeup on, can we move on?" Dipper asked as he attempted to search the room for his clothes with his peripheral vision.

The red ghost chuckled. "Oh sweetie, we've only just begun!"

Out in the mansion's sizeable backyard, Pacifica was running faster than she could ever recall in her life. (Except maybe that time with the golf ball people.) The green ghost's choice of fashion, combined with the fact she didn't actually have to run, gave her a distinct advantage. The mud-spattered dress blended surprisingly well with the verdant acres of the lawn. Were it not for her carrot-colored tresses, the ghost would have flawless camouflage.

As a result, the ghost's game of "tag" had quickly evolved into hide and seek.

"Ghost?" Pacifica called as she carefully picked her way around the mud puddles left by the storm. "Look I'm not in the mood for playing games! My parents are going to be home in a couple of hours and they're already mad at me for what happened with the other ghost. I don't need to add fuel to the fire."

A faint sigh seemed to come from everywhere and nowhere. "And here I thought you'd be different. But I guess you're just as pretentious and stuffy as every other Northwest!"

Pacifica felt a cold set of hands on her shoulders.

"If you won't be it, I guess we'll just skip back to my turn!" The green ghost cheered into Pacifica's ear. "Tag, you're it!"

The hands shoved her forward and Pacifica suddenly found herself toppling into yet another mud puddle.

Mabel opened the polished doors to the mansion's kitchen, glancing about the pristine interior.

"Hey, ghost!" She shouted. "I saw you come in here, don't bother trying to hide!"

A mirthless chuckle drew her attention to a table in the corner, where the blue ghost girl sat beside a massive multi-tiered chocolate cake.

"Do you know why this cake is so expensive?" She asked Mabel.

"Because it's delicious?" Mabel guessed.

"This cake," the ghost continued, gesturing to the cake as she spoke. "Is made using a rare type of cacao bean that only ripens fully every ten years. Some call it the taste of heaven." The ghost pulled a knife from nowhere and sliced a healthy portion of the cake before holding it out to Mabel. "Care to try some?"

Mabel smiled. And Dipper said ghosts are natural trouble makers. "I would love to!"

The ghost grinned crookedly as she motioned for Mabel to come closer.

Mabel obliged. She was reaching for the slice when suddenly, the ghost slammed the chocolatey goodness into Mabel's face before laughing hysterically.

"I can't believe you're so gullible!" She crowed.

Mabel wiped the cake from her face, poking her tongue out to lick some of the frosting. "Wow, this is really good!" She chirped as she reached for the cake. "You should try some!" And with that, she threw her own piece of cake into the ghost's face.

For a moment, the blue ghost simply sat there in shock, chunks of chocolate dropping onto her lap. Then she narrowed her eyes. "You're going to regret that."

The cake was engulfed in a pale, shimmery aura as it floated off the table until it was hovering over Mabel's head.

Mabel stared up at the massive confectionary with a sharp feeling of dread. "To quote Grunkle Stan," she said shakily. "Hot Belgian waffles!"

About forty minutes after the chase had begun, the three pre-teens reunited in the main hall of the manor. Pacifica disheveled and coated in grass stains and mud, Mabel covered head to toe in chocolate frosting and Dipper-

"Is that my dress?" Pacifica asked as Mabel struggled not to laugh behind her.

Dipper glared at the both of them from beneath the false lashes stuck to eyelids. "The ghost insisted on giving me a makeover. Also, I'm pretty sure she stole my clothes."

Mabel snickered. "Purple's a good color on you bro-bro."

Dipper chose to ignore his sister's comment, instead turning to Pacifica. "How do you even wear this stuff? It's all so uncomfortable."

Pacifica smirked. "Welcome to the wonderful world of women's clothing, where comfort and pockets are known only to the imagination." She pulled a small handbag from a nearby closet and removed a small white package, which she handed to Dipper. "I'm guessing you want that makeup off."

Dipper opened the package to find a set of cleansing wipes. "I officially take back what I said about you being the worst."

"Aw," Mabel whined as Dipper began to wipe the makeup off. "I was hoping to get some blackmail pictures."

Dipper cleared his throat. "So Plan C was a failure-"

"Plan C?" Pacifica asked.

"Plans A and B went out the window as soon as they split up," Dipper explained. "I don't think we can exorcise these ghosts. All my equipment was in my vest, which as you can see," he gestured to the dress. "Is gone now!"

"So you're just giving up?" The now-familiar voice of the green ghost chimed in.

Much like before, the three ghosts were hovering in front of the staircase.

Pacifica refused to make eye contact, focusing instead on pulling the leaves from her hair. "Yeah. Isn't that what you wanted?

The green ghost grinned. "Are you kidding? Escaping you guys was the most fun we've had in ages!"

The other two nodded.

"We've been bound to this house for such a long time," The red ghost said.

"And the Northwests are unbearably dull," The blue ghost added.

The green ghost shivered. "So many snobby parties."

"So we're willing to make a deal," The three ghosts finished in unison.

"You have a little fun with us," The red ghost started.

"And we'll make certain your parents are none the wiser when they return," The blue ghost finished.

Pacifica looked up from her hair. "Can you really do that?"

The green ghost grinned. "Did I manage to steal your diary?" She pulled a pink book with a busted padlock out from behind her back. "It was a boring read, I really hoped you'd have deeper secrets than liking deep-fried food."

Pacifica snatched the book out of the ghost's hands. "Okay, you can do it. So what do you mean by fun?"

"Games!" The green ghost shouted.

"Makeovers," The red ghost said with a flip of her hair.

"I have a lot of depressing poetry about the mundanity of the afterlife," The blue ghost droned.

Mabel stepped towards the red ghost. "Well, I like makeovers!"

"I'll play games if it means I get my clothes back," Dipper said as he stepped toward the green ghost.

"And your poems can't be any worse than my father's speeches," Pacifica teased with a smirk in the blue ghost's direction.

"Great!" The green host enthused before swooping over to grab Dipper's arm. "Let's hunt down your clothes!" She took off past the staircase as Dipper made a futile attempt to point out they were going the wrong way.

"We're gonna need that chocolate off so I can access your face," The red ghost declared as she brushed some frosting off of Mabel's cheek.

The two headed down a hallway together, with Mabel starting a conversation about some duck show where the main trio also dressed in red, green, and blue.

The blue ghost positioned herself in front of Pacifica and cleared her throat dramatically. "My first piece is titled And the Tearful Roses Bloom No More."

Sometime later, the two trios reunited at the front door of the now meticulously restored mansion.

"So," Dipper started. "I guess this is it now."

"It's too bad," Mabel murmured. "The second part was actually really fun."

The green ghost poked Mabel's nose. "Don't act so glum! It's not like we're going anywhere!"

The red ghost nodded. "We only agreed to clean up, not pass on. We'll be haunting this place for a lot longer before we move on."

The blue ghost crossed her arms. "Just call for us if you want to cause some trouble, or whatever."

Pacifica titled her head. "Call for you?"

"Oh right, we haven't properly introduced ourselves. Doy!" The green ghost said as she facepalmed. "I'm Carla!" She pointed to the blue ghost. "That's Marta."

"And I'm Maria," The red ghost finished. "If we were still alive, I think we'd be your cousins."

Pacifica smiled. "Well, it's nice to know I don't have to worry about being alone anymore." She opened the door to reveal a waiting limo before turning to the twins. "The butler will take you home, thanks again for helping me out."

"Thank you for saving us from boredom!" Mabel called as she bolted to the limo.

"Let's try not to make this a regular thing," Dipper added with a nervous chuckle.

Pacifica turned to the ghosts. "Any other supernatural housemates I should be aware of?"

"The chef is a selkie," Marta stated dryly.

"I don't think we need to worry about that," Pacifica responded. She reached to close the limo door. "See you around Pines."

The twins both waved goodbye until they passed through the front gates.

"Well Dip-Dop, I think this was a pretty good day," Mabel sighed as she leaned back into her seat.

Dipper seemed distracted by something outside the window. "Hey Mabel, did we tell anyone where we were going?"

Mabel shrugged, "I dunno, why do you ask?"

Dipper pointed out the window where a hastily drawn Missing poster was taped to a stop sign. The fact that the word Reward was followed by a question mark made it pretty clear who made it.

Mabel's grin quickly shifted from content to nervous. "Well, we're in trouble."

Dipper silently nodded in agreement.

So, this was the first request I've ever done. JBlaser, I hope this one-shot served as a satisfactory adaption of your concept! (Carla, Marta, and Maria are their characters.)

To anyone else interested in making a request: I have two multi-chap stories going right now and barely any time to write for either of them. As such, I will not work on any requests until at least one of them is finished.

I hope you all enjoyed!
