"Okay kid, listen up." Stan was standing in front of Casey, who was looking eager to start a brand new day. Dipper and Mabel peeked up from behind a counter.

"I have absolutely no clue about any Scottish history, so basically you'll be working for me and possibly getting into shenanigans with those two," he pointed over to Dipper who smiled nervously, and Mabel, who smiled widely and frantically waved over at her, "get into. Got it?" Casey shook her head.

"Good. Here's a broom," he threw a broom down at the girl, "don't touch the merchandise." He started to leave and Mabel rushed over to her and whispered loudly in her ear.

"You can call him Grunkle Stan, cuz he's our great uncle and his name is Staaaaaan!" Gruncle Stan quickly turned around.

"No. I don't need any more rascals calling me that, you two are enough." Mabel nudged Casey who giggled as she picked up the broom.

"Thanks Grunkle Stan!" The two young girls giggled as Grunkle Stan scowled and walked away. Dipper joined the girls as Grunkle Stan left the room.

"So, Casey…why'd you want to stay here for the weekend anyways?" Casey looked at him and sighed.

"Well…I mean, here wasn't my first choice but I couldn't find any other opportunities. My dad's Scottish and he makes my mom and I go to a Highland Games Festival every year no matter where it is. Since there was one in Oregon this year, we took a road trip from our house in California."

"But aren't they usually fun? Full of manly things to do and the food and…stuff?"

"I enjoy doing boy things, but those are…th-they're just too manly!" Mabel and Dipper tilted their head in unison.

"Too manly? How can anything be…wait…never mind." After spending a day with Manotaurs, he understood the term but couldn't get his head around the concept coming from the new girl. She shivered in response before talking.

"You know how the Scotts wear kilts?"

"Yaaaaa?" The twins said in unison.

"I saw…I saw…" Casey's eyes widened and she dropped the broom.

"You saaaaaaaw?" The siblings were intrigued.

"The horror...the horror!" Casey then dropped to the floor.

"Go oooooonnnnn…"

"The men…wear the kilts…traditionally." Mabel and Dipper gasped, and Mabel rushed over to her. Dipper re-thought his actions.

"Wait, what? What's traditionally and why is that so scary?"

"Dipper! Shhhhh, it's okay Casey I understand."

"I-I was only t-t-teeeeeennnnn!" Dipper saw this as an opportunity to continue making conversation.

"So that makes you…eleven? That's ok we're twelve. You know, big kids…almost thirteen…"

"DIPPER!" He held up his arms in a "whaaat?" matter as his sister scolded him.

"Hey Casey, you wanna go outside and test out myyyyyy…" Mabel dug into her pockets, "Grrrrrrapling hook?" This made the sobbing stop.

"A grappling hook? Cool!" Casey stood back up, pumping her fist in the air, "Grunkle Stan won't mind?"

"Of course not silly!" Mabel ruffled her new friend's hair, "C'mon let's go!" The two ran outside, leaving Dipper confused. He looked around and saw Wendy chilling out at the cash register and reading a magazine.

"Hey uh...hi there Wendy!"

"Hey Dipper. Getting the hang of the new kid?" She turned the page.

"Uuuummm…what does it mean to wear a kilt 'traditionally'?" This made the teen look up.

"You really don't know?" Dipper shook his head 'no' in response and Wendy mischeiviously grinned.

"Well…"

"And then, he turned out to be a bunch of gnomes and they were all like 'marry us so you can be our queen'!" The two laughed and stopped by some trees a little ways from the Mystery Shack.

"Gnomes? In the forest? That's so cool! What else is in the forest?" Mabel shrugged.

"Iiiiii don't know! Dipper said there were these things called Manotaurs that lived in the mountains but I wasn't there. I was helping Grunkle Stan getting a woman when that happened!"

"Oooooh, how did that turn out?"

"She calls a lot and Grunkle Stan doesn't know what to do. Hey do you know what to do?" It was Casey's turn to shrug.

"I don't know. I've never really thought of things in that way." Mabel was about to comment when she noticed Dipper coming towards them.

"Hey guys! Hope I didn't miss out on the fun! Oh and uh Casey…sorry about not knowing…you know…" She held up a hand to stop him.

"So long as it's swept under the rug it's all good Dip!" She turned to Mabel, ignoring Dippers confused face at the nickname 'Dip', "How about that grappling hook Mabel?" Mabel smiled wide and handed her the device. Casey aimed at a high branch and pulled the trigger. The hook latched on and had the young girl zip through the air. She circled the branch a few times before landing down on her butt, giggling. Casey put her legs on the right side of the tree, hung down and put her arms across her chest.

"Vampiiiiiirrrrrrrrrre!" She then stretched them out, wiggling her hands and making a scary face, causing the twins to laugh. Mabel held her hands up to her and danced from side to side, "C'mon throw the grappling hook down, I wanna get bitten!" The group continued to laugh as Mabel and Dipper joined her on the branch.

"But no seriously, please bite me?" Casey looked confused at the request, while Dipper awkwardly punched his sister on the shoulder.

"Don't listen to her, she has this obsession with vampires."

"It's not just an obsession! It's a beautiful obsession." Mabel emphasized the word 'beautiful' by spreading her hands across her face, with her eyes sparkling. Casey's face however, became dark and mischevious.

"Have you ever heard the tale of…the Boabhan Sitttttthhhh?" The twins looked at her in confusion and Mabel raised a hand, shaking it furiously, "What's a bobhand sif?" Casey rolled her eyes.

"Bo-ab-han Si-th. Apparently it's this old Scottish folktale. The creature is an evil and dangerous female vampire who preyed on unwary travelers in the mountains. There's this tale how four young friends set off on a hunting trip and as darkness falls they take refuge in an abandoned cottage. They start to tell the usual camping tales and entertainment and stuff and then…one of them wishes they had more female company among them."

"So uh, what happened?" Dipper gulped. He looked over at Mabel who was wide eyed from the story telling.

"Suddenly, these beautiful women showed up! It was as if they came out of nowhere, and began to dance with them. One of the travelers went to get some music, so he left the cabin. But then, when he came back…" She paused for dramatic effect.

"Blood was on the floors and walls of the cottage. The beautiful women became deadly creatures of the night! And the lone survivor ran for his life."

"Wow! Did the others get turned into vampires too?" Mabel was enchanted with the tale, Dipper was a bit nervous.

"What happened with the other guy? Did he escape?" Casey just shrugged at the answers.

"I don't really know. My dad likes to tell me the lore during dinner and I usually space out towards the end or leave when I finish my food."

"Hey doods!" The kids looked around for the interruption.

"Doods, down here!" The three of them looked down to see Soos waving up at them. Mabel pointed at him and turned to Casey, "That's Soos! He's Mr. Fix It Cool Guy around here!"

"Hey new dood! Doods, I need some help moving a few things, mind giving me a hand?" The three shook their head 'no' and began climbing down the tree.

"Great, thanks guys! I found some stuff upstairs and they need to be moved. Shouldn't take too long though." The four walked back to the Mystery Shack, but Dipper paused to look back at the forest. He quickly shook off the tale though. It was Scottish folklore and they were in America. There couldn't be any Boanhan Sith's in there…

Hahahahaha

Dipper heard more laughter. This time though, it wasn't the high-pitched laugh he heard in the attic…it was female…he looked over at Mabel and Casey. They were almost near the Mystery Shack. Dipper took another glance at the forest and then rushed over to the group. There was just no way Scottish folklore could be anywhere near here. But then again…

This is Gravity Falls.

A/N: And let the Scottish folklore begin! Once again, I'd really appreciate the criticism! If I get the characters a little too OOC, just tell me! And to marcelinefan, I haven't watched the Regular Show yet, but it's on my list of shows to watch so I'll consider your suggestion!
