It was Summerween and The Third Summer for The Mystery Twins. After Weirdmageddon Summerween's tradition was nearly extinct thanks to the copious amount of PTSD generously given by the ruler of the Nightmare Realm and considering no one was in the mood of reliving that experience by cosplaying as monsters, even though the citizens of Gravity Falls have become well-acquainted with the Supernatural inhabitants there was no Summerween Holiday for some time. Fortunately, thanks to the magic of therapy, The Stans, a couple of rebellious teens and time the Holiday has returned during the Twins' Third Summer, with the teens in question including the Pines siblings having a campfire together in the woods. It wasn't an easy task thanks to the Mayor becoming a sniveling mess every time he is reminded of Odd-Apocalypse and it was a long process, yet eventually, Cutebiker became comfortable enough to let the Holiday be brought back.
Dipper and Mabel with other teens which included their best friend Wendy, the girls Candy and Grenda, the emo of the group Robbie and his on and off girlfriend Tambry(Let's just say their relationship had a lot of ups and downs), Thompson(because why not?), Gideon who was now technically almost a teen, Pacifica the heiress of her now somewhat rich parents(who she blackmailed by bringing the "Bell" thing to child services which made her father both annoyed and proud at the same time), and the two doofuses Nate and Lee all were circling around a campfire somewhere outside of the town swapping stories, having laughs and sometimes like all teenagers having sparred with each other, like seeing who has the worst track record on relationships.
"-Believe me, Paz, no one tops on having a disastrous romance life as me." Dipper's sister informed Paz with a slight cringe at being reminded, with Gideon looking sheepish with Dipper glaring at him.
"Not as atrocious as the Princess of the wild woods' relationships I doubt," Pacifica noted in a ridiculed tone.
"HEY!" Wendy outraged.
"The tattoo guy, the Volleyball jock…" The blonde counted with her fingers "him." She nodded to Robbie.
"HEY!" Valentino outcried.
"You can't blame me for this, it's true." She shrugged.
The Redhead groaned "I swear you make some bad choices in pursuing relationships and everyone would hold you for life for it…" she muttered with Robbie muttering as well, although much emo-ish.
"Welcome to womanhood," Tambry said with a smirk at her best friend being made fun of for her rather low standard in pursuing relationships.
"Ah, enough with teen drama will ya? This's Summerween, we' suppose to swamp horror stories, not bein' swapping scandalizes like some Beverly Hills movie." Gideon suggests to the group, getting really tired of all the teenage drama.
"Yeah, the little dude is right, this is the perfect time for spooking!" Nate agreed.
"Or We can do that game in which each time someone loses a bet, they would lose their clothes!" Candy advised with a rather too-looking forward tone, after that everyone looked at her with weird looks "Or not." She decided to drop that, feeling the weight of everyone's gaze.
"AGREE! NOTHING PUMPS YOUR BLOOD LIKE A GOOD HORROR STORY IN THE WOODS!" Grenada concurred.
"E-everyone hold me if I get a panic attack, I don't do well with horror…" Thompson stated.
"Dude, are you still haunted by that movie? It wasn't even a horror one, it was a comedy!" Lee bellowed out.
"It gave existential crises…" The chubby boy stated in a fearful tone.
"There was…"
"I swear if you mention that Road Trip fiasco, I will matchmake you with a Leprecorn!" Mabel threatened Candy from talking about their trip on a van with Stan during the first summer which she drew back to do so, to this day that event made Mabel, Dipper, Grenada, and Candy recoil at how stupid everything about it was like some poorly made fanfiction, Candy had a temporary crush on Dipper, Mabel was a hypocrite and a jerk, Dipper took the worst lessons from her sister and grunkle, there were spiders and that was an astounding achievement considering the very idea of having a road trip when Bill was still around and the Unicorn shield was activated just then came from the supposedly self-proclaimed genius of the Pines Family Ford Pines! Not to mention they basically left those Spider-people to continue feasting on humanity until some chainsaw-loving lunatic decided to have a visit there, let's just say since then the Jorōgumo race learned to fear humans, and later the news said that the place got lit up in fire by some freak accident.
"What about you dude? I bet you saw a lot of scary stuff!" Lee looked over to Dipper, who was like a little brother to him.
"Oh, you have no idea! In fact, let me get my phone…" He put his cup on the wood and brought his phone from his pocket and proceeded to search for a video he was looking for, he got a new phone to stop Mabel from her continuous teasing and being privy about his media history.
"Ah, right here." He showed the screen to everyone as they turned their eyes on it, it was one of his Dipper's Guide to the Unexplained videos he had with his sibling during the First Summer and it just happens to be about The Island Beast which they come across, the video was of them running on a boat frantically running and shouting from a giant disgusting Island with a mouth of human-looking teeth and glowing milky eyes, seeing that promoted everyone to startled and disgusted with Tambry leaving her phone and Thompson with a yelp fall backward.
"That's one ugly fudger right there." The dyed-haired girl commented.
"Ew, it looks like one of those creatures from Never Mind All That but with a severe deformity." Pacifica was repulsed by seeing this creature.
"I guarantee you, it gets even scarier if it's played backward!" Mason played it backward which turned the entity's gibberish into a comprehensible speech.
"YOU DARED INTERRUPT MY SLUMBER! ENTER MY MOUTH CHILDREN! ENTER YOUR DESTINY!"
Everyone sit silent, Robbie was paler than usual, Gideon looked at it with morbid fascination, Tambry for once left her phone, Wendy looked outraged at the fact that his two favorite people were nearly eaten and had thoughts of ways to make the abomination pay, the now returned Thompson was agitated in fear sweating, Grenda and Candy were holding hands, Lee and Nate looked in fear.
"Dude…that's straight out of a horror movie!" Nate uttered.
"I think I'd rather go to the pool from now on…" Tambry muttered, throwing any idea of swimming there.
"Don't worry, our great uncles have dealt with it," Mabel assured them.
"Dealt like how?" Thompson questioned.
bang!bang!bang!*a series of superheated plasma hit on a small island, burning one of its trees and a bush, resulting in the Island floating up and revealing its hideous true form
"YM TPURRETNI OT SERAD OHW…"
It was cut short upon seeing a boat with two angry old men with the intent of murder, one had his brass knuckles ready and the other with a blaster still smoking from the shots now leaving it and readying a much bigger scifi rifle and pointing it at it.
A powerful beam of energy hits after the rifle is charged and it with everything got swallowed by an intense light.
"Let's just say, you're lucky you've never been on their bad side." Mabel's brother informed everyone with everyone accepted that explanation.
"Next me! Next me!" Gleeful brought one hand up.
"Alright Gideon, it's your turn." Dipper gestured.
"There was one time a boy wanted to get his hands on a limited edition train toy, he holds money, especially for that. Until some kid older than him bought it just the minute the boy set foot in the shop with his money, he at first tried to use the money in bribing the older kid to give him the toy but he refused, anger at such a prospect of not getting what he wanted he used his money to buy a grimoire from an antique shop, he summoned a demon to get that toy and made a deal with him; however, the demon done more than that and brought his corpse, the boy was not pleased so he said 'Why did ya do that?' so the devil said 'You didn't put any limits on the contract.' so he disappeared out the blue leaving the kid to drag the corpse and bury it in the backyard of his when his parents were out of the house, by then maggots were feasting upon it and reeked, the police never found the corpse after the boy buried it as fertilizer for his garden.
Everyone where quiet, this time for a different reason, everyone looked at Lil suspiciously with Thompson nudging a bit away his seat from him, and that was when the white-haired boy registered what this is all about.
"Oh come on! do y'all think I would low myself to deal with otherworldly powers over some toy like a petulant child?" he protested scandalized.
"Yes."everyone at the same time answered which caused the Gleeful boy to sour, even to this day no one let him forget about his "Phase".
"Anywayyyyy, I have a story to tell so everyone listens!" Sometimes Tambry's boyfriend decided to tell one. "It was during a storm, a guy got stranded in a snowy mountain due to his plane crashing, he was the only survivor, after hours of scavenging around the crash site for food, equipment and anything that could help him, during the night, he heard the flaps of wings of something big near him when he was cooking some meat on a stick near a campfire. He looked around and saw something in the dark." By then he grabbed his phone to shine a light on his face as everyone looked in anticipation. "HOOT! It was the Owlman stealing his biscuits!"
Everyone was silent for almost 30 seconds, before-"...*BUFF*!HAHAHAHA!" Everyone laughed their butts off to the surprise of the thin teenager, everyone laughed at his supposed "Horror story" and the poor execution to the point that one time Grenda unintentionally smacked the back of Lee with enough force that he fell, Dipper's contrast to his twin sister was trying hard to not laugh in failure and Wendy and Tambry had to support each other to not fall.
"Th-that! That was the worst horror story I ever heard in my entire life!" Mabel stated as she slapped at her own knee, thus Robbie scoffing.
"W-Well, if you can do one better, just tell us!" Wendy's sorry excuse of an ex said with an annoyed look with his hands locked together.
"My turn now!" Mabel declared with a clap on both of her hands. "A lot of bad things happen that authorities try to hide and Gravity Falls is no exception.'' Everyone rolled their eyes, being reminded of the 'Never Mind All That' act. "A string of murders happened, tourists, loners anyone during the night randomly were killed by the killers, with such efficiency that the authorities couldn't find any clue, no DNA, no fingerprint just the body of the victims in a grizzly fashion with every scene looking like a work of art and worse, the murderer had a help as my bro gather looking at the evidence, a dynamic duo with unknown motivation and both of them still out there somewhere….waiting." She gestured dramatically, everyone was leaning with interest.
"Well, that's something…" Gideon wondered, "But wait, I have lived in this town my whole life, how come I never heard anything about it?" Wendy questioned, still in her facade of coolness to pretend like she didn't find the implications of the story disturbing.
"Simple." Dipper gave a sly look. Suddenly, his expression darkens the same with Mabel, although in Mabel's case she was smiling sinisterly. "The Murders haven't happened yet.''In one swift move Dipper throws his cup of water on the fire and everything goes dark.
When the realization hit like a brick, everyone immediately reacted, screamed, and shouted, Thompson, yapped and fainted as he fell from back again, and Pacifica jumped into the nearest person's arms which was none other than Wendy(Which she denies that ever happened), Grenada and Candy were hugging each other as their very life depended on it, Lee and Nate tried to run only to hit on each other and drop in an awkward position, Tambry frantically wrote her testament on her phone and Gideon shout his own eyes as if he expected this to happen.
"I KNEW IT! I KNEW THEY WOULD FINALLY LOSE IT!" Robbie yelled with one finger pointing at the twins while he was up.
The twins looked at them with a poker face that serial killers would wear, until they bellowed out in a fit of laughter whilst tears came from their eyes from the sheer laughter like hyenas, with Mabel turning her phone's flashlight on herself so as her bro, both desperately trying to make sure their phones didn't fall off their hand. "OH, THAT WAS PRECIOUS!" The brunette girl wiped a tear from her eye with the bamboozled gang looking at her, finally understanding that they have been played, Stan would be proud of his Great-Niece and Great-Nephew if he ever learns about them fooling everyone.
The group had a variety of reactions, Thompson still fainted, Wendy was laughing like a horse and dropping Pacifica who looked in an undignified face, Grenada finally stopped hugging Candy who was suffocating as she tried to breathe, Lee and Nate finally got up, Gideon opened one eye to make sure he wasn't dying, Tambry erased her testimony and Robbie who at first was in disbelief until he sits on his chair and grumbled like an Old Man.
"That wasn't funny!" The Blonde barked indignantly.
"Totally it is!" The Girl Pines nearly collapsed, and Gleeful slowly started to chuckle.
"That acting slapped dude!" Nate came close and gave a high five to the brunette teenage boy.
"Wait… what do you mean 'losing it?" The Pines boy asked after giving the high five.
"Well…"- Lee crooked his head, "we kinda made a list of people likely to go insane, with you the 4th, FYI I was against you being added to the list."
"Who is the top?"
"The 3rd is Mabel, the 2nd is Stan 2 and the first is Stan 1," Tambry informed
"*buff*I'm only third? I have to one day fix that." Mabel planned with a mischievous look.
"Please don't," Dipper begged her.
"Too late broseph!" She announced with her brother and everyone in a collective groaning, with Dipper with one hand on his face, except for Gideon who seemed to encourage this.
Just then movement from the bushes was heard. "What's that?" Lee quizzed, everyone looked over the bush, there was no longer any movement from it but they did hear sounds of running before it disappeared, it was dark so they couldn't see what it was running.
"WHAT'S THAT?" Grenda quizzed.
"Eh, probably just a wild animal." Wendy shrugged.
Down in a basement filled with antiques and weird junk from a couple of Journals with the mark of a Pine Tree to weird taxidermy of a monkey and a fish, a poster of Ford that said in an alien language 'Rick Was Here', a music box which seemed to lost some gems from holes in which it supposed to contain, a skeleton the size of a backpack which looked like a combination of canine and feline characteristics with two horns, a cannon that shoots chainsaws, a pot with luminous mushrooms, a sword made out of crystal, some alien and futuristic tech such as disembodied pieces of a magenta blaster, a dead robotic squirrel with thrusters, and a very angry Mongolian Sand Worm inside of an aquarium, three redhead kids at the age of 12 appeared out of nowhere.
"I told you messing with time is a horrible idea!" a redhead boy remarked.
"Well, it's not like I intended for us to meet our younger parents! I was meaning to go back in time during the 19th century for my history assignment!" a 12 years old redhead girl refuted.
"Normally, I'm all for chaos but I would rather not accidentally stop our parents from ever tying the knot, there is no telling what would happen if that happens! What if we cease existing, creating multiple timeline branches, or heck, end up being someone else's children!?" another 12-year-old girl with puffed-style hair and glasses widened her eyes at such implications.
"I get it, I get it, time-traveling is off the menu!" Annabel shook off and put the Time-traveling tap away on a shelf. "I don't like time travel anyway, It is too convoluted, and rarely makes any sense."
"Good thing Mom and Dad don't know about this, or we would be groundedagain." the only male of the triplets sigh in relief.
"YOU'RE ALL IN AN UNIVERSE OF TROUBBBBLE!" The triplet's furious mother who was none other than Wendy flipping Corduroy herself roared in such a volume that even far away from the basement, they could hear her, somehow she found out that her and Dipper's kids were messing with forces of time and she wasnothappy.
Annabel grimaced as if she was expecting Ragnorak to come toward her and her siblings "You just HAD to jinx it, have ya!?" Ava gritted her teeth at the now embarrassed Tyrone.
