It was a bright morning in Gravity Falls. The museum was going to open in an hour. Ford walked in the main room and looked around. He saw his Mabel still reading his journal, Dipper watching T.V, and Soos looking confused at a fuse box. 'Hmm, that's three of my staff. But someone is missing.' He thought to himself, he looked around and sighed. "Where is Robbie?" He said in an annoyed tone.

"Don't worry Mr. Pines. I'm sure he'll be here before the shop opens." Soos said smiling.

Ford scratched his head. "I hope your right Soos." After a few minutes there was a rush of cold air though the shop. "About time." He said as he turned to the door.

Robbie smirked alittle and closed the door behind him. "Relax Boss. I'm here before the store opened right?" He said before stepping behind the cash register.

Ford folded his arms and sighed. "Yes I suppose you are. Get ready everyone, we're going to open in a few minutes."

As time went on people filled in store and looked around the museum. Mable was cleaning the floors when she heard Robbie call over to her. "Hey Mabes, can you watch the register for a minute? I need to go talk to my friends real quick."

Mable struggled to hide the fact that she was blushing. "Uh hehe, yeah sure Robbie. No problem." She grinned nervously.

Robbie smiled and stepped away from the register. "Thanks Mable, I owe ya." He said before going outside.

Mable stood in front of the register and looked around the store before hearing a familiar humming beside her. She turned to see her brother smiling smugly at her. He grinned. "You like Robbie." He said in a sing song voice as he swayed back and forth on his heels .

Mable bushed and turned away. "N-no I don't!" She said quickly.

Dipper smiled and punched her arm lightly. "Don't lie to me Mable. If you don't admit it, I'll just have to talk to Robbie about it." He snickered.

"Alright Alright Fine! I might, maybe, sort of, kinda like him, alittle." She said as she scratched her head. "Just... please Please don't tell Robbie alright?! It's just, he works here every day and I have to see him and he's Alot older than me."

"He's like... three years older than you. It's not That big a different." He interrupted her. "Mom and Dad are eight years apart."

"It's different when you're still kids alright?" Mabel saud quickly. "Dipper just Please don't tell him, it would be weird between us if he knew."

Dipper sighed but nodded. "Oh alright fine. I promise I won't say anything." Dipper wasn't above embarrassing his sister, he's done it before. But the last thing he wants is Mabel holding a grudge against him over Christmas break.

Mable sighed and smiled at him. "Thanks Dip." As she said this she saw Robbie coming back.

Robbie walked up to the two and smiled. "Thanks Mabes. I can take over again."

"Uhh, No problem Robbie." She said looking down, she wasn't blushing as much now but she still tried to hide it

"So what were you guys talking about anyway?" Dipper asked sitting up on the counter, something he Wasn't suppose to do.

"Oh we were just talking about where we were going to hang out tonight. I think we're gonna hang out at the old grave yard. People in the town say it's haunted." Robbie said stepping behind the counter.

Suddenly Mabel's shy behavior started to fade as she looked up.  "Grave yard, haunted, Ghost?" She said excitedly as a smile came to her face.

Dipper chuckled and rolled his eyes. "Oh boy. Here we go again."

Robbie quirked his eyebrow looking down at them. "What?"

Dipper looked from his sister then back to Robbie then grinned. "Mable knows like, Everything about ghost. She's spent most of her life learning about that stuff." He said chuckling

Robbie was quiet for a second, a somewhat contemplated look on his face. "Huh, really? Well hey, you guys wanna come with us?" He asked.

"We'd Love To! I- I mean... Yeah sure." She said a blush spreading a crossed her face again. "Will your friends be okay with that?" She asked looking down.

Robbie shrugged. "Yeah probably, my friends are pretty laid back. Well... most of them." He said scratching his head. "So you wanna go later tonight?"

"Yeah that would be awesome!" Mable said with a grin, the excitement getting to her again.

Dipper smiled at her and nodded at Robbie. "Sure, I'll go."

Robbie smiled and nodded at them. "Alright, I'll come get you two when I'm ready to go. Till then I gotta focus on work." He said turning back to the register.

With that Mable and Dipper walked away, with Mable having a giddy smile that you would usually see on Dipper's face. "This is going to be so awesome! I can't wait to go!"

Dipper laughed. "I can tell ya big nerd. Just don't full geek on me when we get there alright?" He smirked.

"Oh shut up." Mable said pushing him.

After a few hours and the shop closed Robbie came to get Dipper and Mable. "Alright, you two ready to go?"

"Go where?" Stanford came around the corner glancing at the three of them, getting a nervous grin from Mable.

Robbie smiled and shrugged. "I was just thinking the kids would have some fun hanging out with me and my friends. I just thought it'd be nice if they got some time away from here."

Ford folded his arms. "And What exactly are you going to do?" He asked.

Robbie turned to the side. "Nothing that you THINK I'm going to do, mister Pines." There was a tone in Robbie's voice, but it was hard to make out... it wasn't anger, at least not completely. 

Ford looked at him for a second before sighing. "Alright fine, just don't get them in any trouble."

Robbie looked back at him and laughed alittle. "Are you kidding? After what these kids have been through, we're going to have to be sure they don't get US into trouble."

"Just be careful." Ford said as he walked out of the room.

Robbie sighed and nodded. "Yes sir mister Pines." He said as he turned to the twins. "Alright you two, lets get going." He said before walking towards the door.

Mabel grinned with excitement followed him. "Alright lets go! I can't wait to see what the grave yard looks like."

Dipper chuckled as he walked beside her. "Calm down Sis, your acting more like me than usual." He said jokingly.

Mabel glances and him and lightly jabbed his shoulder. "Oh shut up Dip." She says as they walk outside. Outside waiting for them was three guys and two girls.

Robbie walked up to them. "Dipper, Mabel, these are my friends. Lee, Nate, Thompson, Tambry and Wendy." He then turned to the other. "Guys, these are my boss's great niece and nephew, Dipper and Mabel."

Wendy glanced at them. "So what are they doing here?" He asked in a monotone voice.

Robbie shrugged. "I decided to let them come with us. We were going to the creepy old cemetery and Mabel knows a lot about ghosts. So I thought it would be fun to bring her and Dipper."

"You know everything about ghost? Awesome!" Said Nate.

Mabel smiled shyly and looked down. "Well, I wouldn't say 'everything' but-"

"Oh don't be so bashful!" Dipper said laughing as he turned to the others. "Mabel has been reading, watching, and learning about ghost since she was like... two. She could tell you the difference a residual haunting, a intelligent haunting and a demonic haunting and So many other things." He said then smiled at Mabel.

"Awesome!" Both Lee and Nate yell.

Mabel chuckled and rubbed her head. "Oh come on, you can find any of that in five minutes of searching on the internet." She said quietly

"What ever, can we just go already." Wendy groaned.

"Yeah sure, Thompson do you have your mom's car?" Robbie asked.

"Yeah, but she said you guys can't punch the roof anymore." He said as the group walked to the car.

"Whoo Hoo! Lets Go!" "Yeah! Way to go Thompson!" Lee and Nate yell as they get in the car with everyone else. "Thompson, Thompson, Thompson!" The two chant as he starts up the car and starts to drive, all while punching the roof in spite of what they were told.

"Come on guys, my mom is going to yell at me again." He says as he drives.

After a car ride full of yelling, chanting and general ruckus, they pulled up to the cemetery. The group got out and Robbie walked up to the gate. "Lady's and gentlemen, I present to you, The Gravity Falls Cemetery." He said as he opened the gate. Lee and Nate ran in excitedly followed by the rest of the group.

The group walked in, Mabel looked around and smiled, in the distance she saw a particular large grave stone. "Whats that she asked.

Robbie caught her gaze and looked back at her. "I think that's Andrew Northwest's grave stone. He found the town like forever ago, so they gave him a big grave stone." He said.

As this is going one Nate looked around excitedly. "Wow, look at this place! This is so cool!" Nate said looking around.

"I bet it's full of ghosts and stuff too." Thomson said smiling.

Wendy rolled her eyes. "So what? It's a cemetery, every single one is probably haunted and full of ghosts."

"Actually..." Mabel started. "Spirits usually don't haunt the grave yards as much. It's Absolutely Possibly but... They usually haunt where they died or a place very important to them." She said smiling.

"Right, cause ghosts are drawn to emotions and memories and that's how they get a lot of their energy. Right?" He asked turning to Mabel who nodded at him while smiling.

"You know a lot about this stuff too?" Lee asked.

"Hey, when you live with Mabel Pines for twelve years you have to know a thing or two about ghost." He said smiling at Mabel.

"Seems lame to me." Wendy said looking around with a disinterested look.

"I think it's pretty cool." Robbie said smiling at Mabel.

She smiled and looked down, yup, she was blushing again. "Thanks Robbie." She said quietly as Dipper elbowed her gently, smiling at her.

After some time the group came to a particularly large and old grave tome. "Wow, check this thing out!" Thomson said as he and the others walked up to it.

Robbie walked up to it and whipped the dust off the front of it, reviling some symbol that were unfamiliar to him. "What's this stuff? It's Defiantly not in English that's for sure."

Mabel saw the symbols and and felt a twinge of fear go through her. "Uhh, maybe we shouldn't mess with this grave stone." She said veglly recognizing the symbols. 'I saw these symbol in Grunkle Fords journal somewhere. But what was it..?' She asked herself.

"What, is it a bad thing or something?" Thomson asked stepping back alittle.

"Yeah sure, I bet she's just scared." Said Wendy.

Mabel rolled her eyes and walked forward. "Look, I just know there are somethings you should just do not mess with." She said sternly.

"Whatever, if you really knew what was going on you wouldn't be scared."

This made Mabel stop in her tracks. "I am not scared!" She said turning to her.

'Uh oh.' Dipper thought to himself, knowing where this was going.

Wendy shot a look at her. "Well if your aren't scared then prove it."

"Fine!" Mabel yelled walking up to the tombstone. "This is the markings on this is to summon an spirit called a Graven." She looks at the markings. "Septra naO suwis cal." silence. "I guess I didn't say it-" Suddenly the ground started to shake.

"Wh- whats going on?" Thomson asked.

"Uhh Earthquake maybe." Robbie stated.

"Mable?" Dipper said worryingly looking at Mabel. He had a faint idea of what was going on.

Mabel felt a twinge of guilt at realizing what she had just done. "Uh guys, I really think we need to-" Before she could finish several large cracks formed in the tombstone, each one accompanied by an Earth shattering shake that knocked everyone down. The shaking died down and a green smoke pored out of the cracks of the tomb. What seemed to form from the smoke was a tall bony figure draped in a black cloaked. It seemed limp and lifeless at first but then stiffened and looked around.

"...I have... RETURNED!" It's voice started out low and raspy, but then boomed through the air.

Everyone ran off to try and hide from the spirit. Dipper looked over at Mabel with a bit of fear. "Mable, what are we gonna do now?" He asked.

"Yeah is there a way to get this guy back into his big rock?" Robbie asked with a look of worry.

Mabel looked down with a mix of fear, guilt and embarrassment. "I- I... I don't know."

"What!?" All the other shouted turning to her. This got the attention of the spirit.

"HUMANS!" A thunderous roar came from the skeletal creature as it turned to them.

Nate jumped up and tried to run for it. "I'm getting out of here!" He yelled, he didn't make it far though. The spirit raised a bonny hand levitating him.

"No human escape me." It said in a raspy voice. It looked around and started to survey the area.

Robbie watches then turns back to the others with a few beads of sweat on his forehead. "Guys, I think we're in trouble."

Mabel stumbled back alittle. "Oh man, this is bad, like, really bad. I don't know what to do..." She looked down.

"Wait a minute Mabel." Dipper started. "Isn't there something in Grunkle Ford's journal about that thing?" He asked.

Mabel looked up for a second then gripped her brother in a hug. "Dipper your a genius!" She said before pulling back and flipping though the journal.

Dipper could help but give a little smug grin. "Well, I guess I am pretty smart."

Mabel didn't notice his smug remark as she was quickly flipping from page to page. "Umm lets see, Demons, Shadow Beings, Ghosts, Graven!" She started reading the pages but mostly looking for a specific section. "How To Trap It!"

"Great! So what do we do?" Dipper said keeping an eye on the spirit.

Mabel continued to read from the journal. "Draw these symbols one to a piece of paper, (there is an arrow pointing to a set of symbols and I'm too lazy too describe them. Just imagine Egyptian hieroglyphics or something.) Once drawn, lay the paper on a rock and chant these words, if done correctly the Graven will seem to be pulled inside the rock the the symbols on the paper should be engraved into the rock."

"Is that all?" Dipper said sounding happily surprised. "That shouldn't be too-"

Mabel still had a worried look to her. "Uhh Dip. It's gonna take me a minute to draw these."

Robbie looked down at them before getting up. "Take your time, I'll keep the thing distracted."

Mabel looked up as did Dipper. "Robbie! What if you get-"

"I promised Ford wouldn't let anything happen to you. I'm not going back on that." He said as he made a distance between him and them. Then Getting the Graven's attention. "Hey! Golly! Over Here!" The Graven turned sharply and started to make his way to Robbie.

Dipper watched this before turning back to Mabel. "We gotta do this quick Mabe."

"Working on it." Mabel said drawing the first of the symbols.

The Graven attempted to use a spell a Robbie but he manged to dodge. "Haha You missed me!"

The Graven narrowed his eyes as he swiped at him again. "Insolent human."

"Uhh Mabel..." Dipper started.

"All most done." She said looking from the journal to the paper being sure she was drawing the symbols right.

The Graven Raised his hand causing Robbie to levitate. It laughed deeply. "Gotcha."

"Mabel!" Dipper yelled.

"Done!" Mabel said putting her pencil down. "Now, what rock do we use?" She said looking around frantically.

"Uhh how about this giant rock we're hiding behind." He said tapping on the rock.

Mabel looked at him. "Oh yeah, that will work."

The Graven grinned as he got closer to Robbie. "Is it funny now?" It asked as it was about to perform a spell before getting hit with a rock.

"Hey Spooky! Over Here!" Dipper yelled getting the spirit's attention. Then Graven snarled before dropping Robbie and lunging at Dipper. But before it could reach him Mabel got up and placed the paper on the rock.

The Graven saw that and realized what she was doing. It gasped. "Nooo!" It yelled before trying to fly away.

"Sectreario Niva!" Mabel Yelled, with that Graven started to glow and was puked towards the rock."

"Nooo! Not Again!" It yelled. The ground shook again knocking the twins back as it was forcibly pulled inside the rock. Then everything calmed down.

Dipper rubbed his head and sat up, looking over at Mabel. "You alright Mabel?" He asked with a slightly concerned smile.

Mabel smiled faintly and nodded. "Yeah, are you?" She asked while helping him up.

"Yeah, I'm all in one piece as far as I can tell." He said checking to be sure he had all his limbs and fingers with a goofy grin.

Mabel laughed while walk out from behind the rock. "Well good, I don't wanna have to put my brother back together." She said smiling as they walked up to the others, before her guilt started to come back. "Uhh, hey guys. I'm so sorry about that." She said looking down.

"Sorry? Are you kidding...! That Was Awesome!" Lee yelled excitedly.

Mabel looked up surprised. "Really?"

"Yeah!" Nate yelled "I know we said this place was haunted, but I didn't acutely expect to See a ghost!"

"Yeah, and they way you got that thing back in the rock and everything was pretty cool too. You really do know a lot about ghost." Thomson said.

Tambry just nodded and gave a thumbs up before looking back at her phone.

Mabel smiled at Dipper and they both fist bumped.

"Are you kidding?!" Wendy yelled while walking over. "She almost got us Killed!"

"Only because you were making fun of her before hand." Robbie said with a glare. "And further more..." He started. "At least she actually did something about it instead of running away like you." He said trying to keep from yelling.

Wendy just backed up and looked down. "What ever. I'm going home." She said before walking away.

Robbie sighed and turned back to the twins. "Sorry about her, I know you didn't mean for that to happen. Look, lets just head back. I think we had enough fun tonight." He chuckled

Mabel smiled and nodded before heading to the car with the others.

---

Thomson dropped the twins off at the museum. Robbie, looked over at them before he drove off. "Uhh, we probably shouldn't tell Ford about this. He's already on edge enough." He said smiling.

"Yeah, good idea." Mabel said rubbing the back of her head.

Robbie nodded. "Cool, so, I'll see you two tomorrow then." He said as Thomson drove away.

Dipper smiled and waved before heading inside with Mabel. "Well that was fun. And you got on good terms with Robbie." He said grinning at Mabel.

Mabel blushed alittle and looked down. "Yeah, well at least we're friends now."

"Yeah, and hey, who knows he might actually start to like you like you one day." He said smirking a bit.

Mabel glanced at him and pushed him. "Oh shut it Dipper." She said, though she couldn't help but smile slightly.

Dipper laughed. "Well hey, if that doesn't work, you'll still always have me." He said grinning as he put his arm around Mabel.

Mabel chuckled. "Yeah, I will." She said as the two headed up to their room to get some well needed rest.

Can I just say how difficult it is to represent a charter who is suppose to know EVERYTHING about ghosts when I am  a novices at best. Seriously the extent of what I know about ghosts comes from T.A.P.S and Ghost Adventures.
