Hey guys! So how's Christmas? I think I have the best Christmas present ever! Also so sorry for the super-late update! After Christmas, my family and I went on a vacation for the weekend so that's why I can't update my story. I'm really sorry though. And I'll give you guys my late X-mas present! A new chapter! lol so here's Chapter 4! I think it's gonna be long. cx

Montydragon: Of course we don't go to the same school! If we do, I would have known you! Wait… is that making any sense? Forgot that part. Mabel certainly would be panicky since we all know that she's not that type of person. Hmm… I'll try not to. Rosie is not a too perfect person. She's normal, like Mabel and Dipper. Thank you so much for the review!

ButteredPopcorn: Yes! I'm starting to hate Heather right now lol. Come on, admit it. You ARE nice. Hmm… probably till the end of the story? Who knew, if you had an account, it would make things much easier. Thanks for the review!

StkAmbln: Yes, a very horrible scene XDD. Thanks for the review!

InsanityIsClarity: Hello! ;) YES, I'm super-duper bad at foreclosure and law enforcements. I totally agree with you! Thanks for the review!

Rainboom345: Hey you! Yes, it'll give you nightmares! Lol. Yup that's my hidden talent! *whispers* I'm good at writing horrible scenes. Thanks for the review!

Night had fell as the whole of Gravity Falls darkened. The area now seemed eerily quiet, but was accompanied by the creepy Hoo! Hoo! from the owls in a distance.

Mabel closed the lights in her and Dipper's bedroom. The moonlight was pouring through the window, illuminating quarter of the room. Mabel sat down on the wooden floor, followed by Dipper, Wendy and Soos. She placed a lantern near to them so they could see each other in the darkness.

"Okay, guys. I have a sweet-tasting idea." Mabel whispered. Dipper, Wendy and Soos nodded, already captivated, even though Mabel hadn't started yet. She inhaled slowly. "Soos, you said that music was everyone's favourite to listen according to your cousin Reggie right?"

Soos nodded in response, beginning to listen intently. Wendy looked at Mabel. "So what are you trying to say?"

"What I'm trying to say is that I have the most brilliant idea ever. Try to guess what music was commonly related that can received loads of money," Mabel objected. "There are lots of cheering, screaming, squealing and fangirling!"

Soos clicked his fingers, indicating that he just got the answer in a brief second. "Dudes, I know! We sing music to them!"

"You're right, Soos." Mabel said as she focused her attention to Wendy. "What 'bout you, Wendy? I bet you know if I give you this hint. Whatare the thing in the Woodstick Festival that are related to music?"

Wendy gasped. "A concert!"

Mabel grinned excitedly as she knew they were close to the answer. "So what are these group called when they performed in concerts?"

"A band!" Soos and Wendy shouted simultaneously, raising their arms. Mabel happily enthuses, "Yes! So what are we doing exactly is to form a band that could possibly save the Mystery Shack!"

Dipper didn't believe this. "Woah, woah, woah." He switched on the lights and gazed at the three before he flicked his gaze towards Mabel. "Really Mabel? Are you downright serious?"

'Oh yeah! I am down-down-doooownright serious!" Mabel said in a singsong voice. Dipper shook his head in disbelief. "Mabel, do you know how difficult it is to form a band and organize concerts?!"

Mabel seemed casual. "Ah, how hard can it be, brother?" She stood up. "It's easy if you know how, like me."

Dipper looked doubtful at her answer. "Oh yeah? Well I think you don't know at all!"

"Woah, dude. Calm down. There's no need to get mad." Wendy assured him. Dipper shook his head. "No! You guys don't understand! You think it's easy to form a band? We need a studio to work on, creates dozen of music and I'm not sure you guys know how to play the musical instruments!"

Mabel stood up and gazed at her brother in the eye. "Brother, before you started some misunderstanding, let the girl who understands almost anything explain to you." Dipper crossed his arms, sighing and rolled his eyes in annoyance.

Mabel continued, "Listen here. Do you know that bands had loads of money? They sold their music soundtracks a million copies and you know how much money that can get? Let's give it an example of One Direction. Do you know how rich they are? Also we don't need a studio to work."

"What?" Dipper said in a silent gasp. Mabel nodded. "This is just like a simple band. We can just rehearse in a room. No need to get fancy. If this band gained popularity, I'm one-million percent sure that we can save the Mystery Shack and save ourselves from bullies."

Wendy and Soos glanced at her in confusion. "Bullies?" They asked. Mabel hesitated, and she quickly spoke. "Forget that part. Now… we need to know who can play well in some musical instruments."

Soos placed a finger on his chin in thought. 'But Mabel, do you really think you know everything about bands? I heard that it is pretty sophisticated." He told her. Dipper nodded his head in agreement. "Yeah, Mabel."

"Uh…" Now the twelve year old was lost in thought. She didn't know how to respond to this. Bands seemed pretty complicated if you didn't know very well about it. Her mind was fizzy now with thoughts. She scratched her forehead and think hard. Then a right thought spanned in her mind. She had a braced grin. "No need to worry! I just seek some advice…"

"From who?" Dipper cut her off, folding his arms over his chest. Mabel didn't look worried. "Do you know Robbie has a band called Robbie and the Tombstones?"

"Uh… yeah?" Dipper fretted, anxious of what Mabel was getting at. His twin sister smiled. "Well we don't know and never seen his bandmates before, so I suggest that I want to seek some advice from Robbie about forming a band.

Dipper's eyes widened. "Mabel! Why Robbie? He's still my arch enemy!"

Mabel shook her head and placed a hand on her brother's shoulder. "But he's not angry with me, right? Do you remember that he said thank you to me because I helped him getting a new girl? He's not my enemy anymore. Of course I thought he was a jerk before, but now he isn't. So now I'm friends with him but I'm not sure that he still hates you."

Dipper drew in a breath. "That's what I thought." Mabel twitched her lips. "You guys just discuss about the musical instruments while I went over to Robbie's house."

"Wait… now? In the middle of a night?" Wendy asked, eyes widening. Mabel nodded eagerly. "Yeah! It's okay. I'll be fine."

Dipper called after her. "Be careful, Mabes."

"I will, Dipstick." Mabel replied, a smile forming on her lips before she skipped away.

Mabel slowly walked into the moonlight as dried, fat dead leaves scuttled through the wind. The hoots of owls were echoing from a distance and howls from wolves was heard.

"Okay, this is getting' creepy." Mabel said to herself, shivering from the cold wind that wafted over her skin. The pine trees started to sway side by side in a very deep slow movement. The stars were dim and Mabel wasn't sure she could see any of them glimmering in the night sky. She was sure that this night was going to get really dangerous.

Suddenly, a vicious howl split the air and Mabel was so dead surprised that she began to run towards the direction at Robbie's house in full-speed where she doesn't realize that the bright white moon had a black line across it which creates an eye.

Fifteen minutes later, Mabel finally arrived to Robbie's house called Valentino Funeral Home that was located near the Gravity Falls Cemetery.

"Yokay, Mabel, time to ask Robbie 'bout forming a band." She muttered to herself. She began to press the doorbell and it produced a somewhat creepy sound. Mabel grinned when the door opened and Mr and Mrs Valentino appeared.

"Howdy do!" Mr Valentino greeted and Mrs Valentino added, "Happy day!"

Mabel replied with a smile, "Yello' Mr and Mrs Valentino! Can I come in?"

"Sure you can, little girl!" Mrs Valentino returned the smile and they both gestured Mabel to come in with a warm welcome. When they both settled themselves in the living room, Mr Valentino proffered Mabel a cracker platter. "Do you want some cracker platter this time?"

Mabel had a big braced grin. "Of course! It's rude to refuse the second time! Mwop!" She took the plate with the cracker platter from Mr Valentino's hands and shoved a cracker into her mouth, chewing it properly. Mrs Valentino stood beside her. "So why do you come here in the middle of a night, little girl?"

"Oh, I'm here to seek some advice from my now-friend Robbie." Mabel expound, gulping the cracker she'd ate. Mrs Valentino smiled cheerfully and glanced upstairs. "Robbie Stacey Valentino! There's the same little girl who came to see you!" She turned to Mabel. "You go on up."

"Thank you, lady!" Mabel thanked her and carefully went up the stairs. She slowly arrived to Robbie's bedroom. With a happy smile, she began to knock the door but paused when she heard strange noises coming from the door. It sounded like it was produced by lips and more like puckering. That immediately crosses Mabel's mind. "Couldn't it be… ?"

She suddenly banged the door open and she froze in shock when she glimpsed Robbie and Tambry who appears to be… kissing!

The couple spotted her and quickly react normally. Robbie was quite furious. "Hey, kid! Couldn't you knock first? We sorta had a moment here!" Mabel pressed her cheeks hard, cuteness flooding in her eyes. "I'm sorry I just – aaahhhh I can't take it anymore! You guys are so adorable! I should have takea picture and posted it on everywhere!"

Tambry curled her lip nervously. "But, Mabel… can't you respect our privacy?"

"Aaaaahhhh!" Mabel squealed, but she finally conformed herself. "Sorry, got carried away."

Robbie scratched the back of his head awkwardly. "So… what are you doing here in the middle of a night?" Tambry nodded her head, agreeing. "Yeah," she checked her phone. "It's 1:45am now. Aren't you suppose to go to sleep during that time? And didn't you have school tomorrow?"

"Oh yeah! Darn!" Mabel denounced, but she couldn't forget her most important objective yet: seek some advice from her Robbie about forming a band. She flicked her gaze towards Tambry. "Can you give us a minute? I have something to ask him."

Tambry seemed reluctant, but instead she got up. "If I have to." She muttered before leaving the room with her phone in her hand. After she got out from the room, she shouted to them. "Don't do something crazy!"

Mabel grimaced. "Eew! Why would I?" She then focused her attention back to Robbie. "Hey now-friend! I have something to ask you."

"Uh… sure? Go on." Robbie replied and slowly sat down on his bed. Mabel grabbed a stool and sat onto it. "You have a band right? Robbie and the Tombstones?" Robbie shrugged. "Yeah. Didn't you see my posters?" He pointed the posters he stick onto his bedroom door. Mabel sighed. "Yes, I've seen them! It's obvious." She cleared her throat. "Anyway, I need your advice about forming a band."

Robbie raised his eyebrows. "Wait, you're forming a band?"

"Yes!" Mabel blurted out, remembering the shack and their home that they about to lose forever. "And I need your help! Please!"

Robbie waved his hands at her, trying to calm her down. "Woah, woah alright! I'll give you some advice about forming a band."

"Oh thank you thank you thank you!" Mabel exclaimed, satisfied. Robbie started, "Alright, the first step…"

Thirty minutes later…

"… and that's how you form a band." Robbie finally finishes his sentence. Mabel was astonished. "Oh! It's really surprising that you're a lead guitarist in your band." She commented, smiling. Robbie placed his arms at the back of his head. "Well, that's when you -" he reconsidered something " – wait, why do you want to form a band?"

Tears started to build up in her eyes. She hung her head low. "We're about to lose the shack. We don't have much money to pay."

"W-what? That's impossible, r-right?" Robbie stammered uncertainly. Mabel wiped all the tears from her eyes with both of her hands. "But I know that we mustn't lose hope. That's why I wanted to form a band because do you know how rich they are? Also I want to find more band members for this group."

Robbie's eyes moved sideways in thought. "Well, to find a band member, you must find a talented one. The one who knows a lot about music so it will be easy for you to cope. Alright?"

Mabel gave him a cheery grin. "Thanks Robbie! Wow, you changed quite a lot when you found a new girl." She remarked. Robbie shook his head. "No, it was you who helped me find a new girl! I don't remember that I said thank you, but again, thank you."

"You're welcome, now-friend!" She yawned sleepily. "Now, I need to go to bed and have some beauty sleep. Me dreaming in forever candy world."

"Yeah right." Robbie muttered, smiling. Mabel said thank you once again and a goodbye before she left the Valentino Funeral Home and headed back to the shack.

The next morning, the twins woke early for school. The first period will be starting early and they didn't want to miss it or their teacher will fussed about it. Mabel and Dipper were in their bedroom, putting on their shoes. Dipper glanced up to look at his sister. "Mabel, did you get some advice from Robbie?"

Mabel nodded eagerly. "Yes I did! Don't cha worry. Everything that messes us will soon blown over!" She finally tied up the shoelaces from her sneakers. She's now wearing a gold-orange colored sweater with an image of a baby tiger with an orange headband and skirt. She stood up. "Let's go go, bro-bro!"

The twins went downstairs to the gift shop. Wendy and Soos were in there, chatting and as usual, Stan Pines was waiting in his El Diablo but he was actually sleeping. The twins thought that it is really early to go to school so they used the extra time for a discussion. Mabel called Wendy and Soos over and all them stood in a circle.

"Have you guys made a decision of what instrument will you play?" Mabel questioned. Soos punched his fist in the air. "I did, dude! I will play the keyboard so I will music r-r-r-right!" He said enthusiastically. Wendy looked like she had decided. "I'll be playing the drums."

Dipper stared at her. "You played drums?"

"Yea, my dad brought me to drum class and assigned me for drum sessions. Guess I'm kinda ruled at it." She explained with approval. Dipper raised his eyebrow, surprised. Mabel turned to his brother. "So, what about you Dippingsauce? Did you decide?"

Dipper placed a finger on his chin, thinking. "Well, I think I'll play the electric guitar. I know how to play them but not as much as I play the saxophone. But you know, just practicing it occasionally." Mabel was impressed. "Wow! I'm surprised that I didn't know my brother that well!"

"I think we don't have much band members." Dipper said. Mabel frowned. "What do you mean?"

Dipper expound, "From all I know that we need a bassist. Almost every band has one." Wendy seemed to disagree. "But Dipper, it's impossible. There's not many people in Gravity Falls are talented and knows how to play the bass guitar. It's just like, very hard to find."

Mabel interjected. "Robbie said that if we want to find a band member, we must find someone who knows a lot about music and that'll be easy! Soos, Wendy, you guys check out in the whole Gravity Falls town while me and Dipper check out in school."

"Roger that!" Wendy and Soos did a salute. "Come on, dudes! Let's go and find a B-Assist!" Soos said flippantly. Dipper shook his head amusingly at Soos's meaningless joke.

In a few minutes, the twins ended their discussion and headed outside. Dipper and Mabel spotted their Grunkle snoring in the car peacefully. With a grin, Mabel silently crept beside the front car door beside Stan, intending to wake from his peaceful nap. She took out a horn from her backpack and she momentarily blew the horn. Stan woke up with a surprise and his head was smacked on the car roof. "Whaaat? Where am I?" His gaze was at Dipper and Mabel. "Who are you? Who am I?"

Dipper and Mabel cracked up laughing and for a few minutes, Stan now realizes what happened. "Ha, ha," He muttered. "Very funny."

Dipper put his hand on his mouth, holding back his laughter while Mabel was rolling on the ground, laughing uncontrollably. She slowly stood up and wiped a tear. "S-sweet Gummy K-koalas!" Dipper had finally recovered from the laugh. "Grunkle Stan, you should seen -"

Stan cut him off. "Yeah, yeah whatever. Now stop wasting your time and hopped in the car!"

The twins obeyed and hopped inside and Stan drove off to the direction of their school. For a few minutes, Dipper was looking outside from the window and his eye caught a bandage on Stan's right hand on the wheel. There is a little blood matted on it. He frowned. "Uh.. Grunkle Stan, what happened to your right hand?"

Stan felt a little panicked and he quickly rushed on, "I, uh, burned it on a toaster."

Stan was making toast and was waiting for the toaster to finish. He then pulled out the bread but he doesn't realize that the toaster wasn't finish and he accidentally touched the heater inside that was still heating. His hand burned and he screamed. "Sweet sassparella!"

Dipper and Mabel had arrived to the Gravity Falls Elementary School. They both walked up the stairs and went inside the school with a nervous feeling in the tummy. Dipper said goodbye to his sister before he went off to his Chemistry class.

Mabel walked to her locker and took out her stuff. She started humming random music and when she closed her locker door, she bumped onto someone and books were dropped onto the floor. Mabel reacted faster. "Ohmagosh I'm so sorry!" She grabbed all the fallen books before standing up to return to the person she bumped onto. But then she froze.

The person she bumped onto was actually the girl that everyone was gossiping about. Rosie Redwood. Mabel thought, curling her lip. Rosie seemed casual and she took the books from Mabel's hands before fled past her while saying, "Sorry."

Mabel was still frozen and she slowly turned her head and watched as Rosie left the scene. She was lost in thought. In a few minutes, she left the hallway for Math class. When the first period starts, students were no longer hanging out in the hallway. Mabel sat at the far back of the class and was chewing the pencil as Mr Smith was teaching them about math equation. She couldn't stop herself from thinking about Rosie Redwood.

I don't think she was what she is seems, Mabel thought inwardly. She heard all the stories about Rosie Redwood and all of them sounded ridiculous and doesn't make any sense. Why does everyone taking seriously on this rumors? Why is Gravity Falls residents so weird? Unfortunately, she was thinking so hard that she wasn't paying attention to the class and Mr Smith scolded her. "Mabel Pines, why are you not paying attention?!"

Mabel shook her head, shaking the thoughts away. "S-sorry, Mr Smith!" The class started giggling amusingly at her and Mabel felt embarrassment flushing on her cheeks. Her face flushed bright red with discomfiture and she slowly hung her head. She sighed.

Class started moving on till the end of the period and the hallway was now full again. Mabel had stuffed back her things on her locker and sadly walked towards the hallway. Still no friends. Mabel thought dejectedly. She was trying herself so hard to make new friends but she failed. None of her plans to get their attention worked.

As she dolefully walked in the hallway, she heard noises from the music room she had walked past. Curious, she looked around, hoping no one sees and opened the door a crack. She narrowed her eyes, eager to see who is inside. When she saw someone in there, her eyes adjusted the person's appearance. Her eyes widened when she clearly saw who it was. Rosie Redwood?

What is she doing in the music room? Without asking herself any more questions, she focused on what the mysterious girl was doing.

Rosie was holding a stunning bass guitar as she adjusted it properly. Mabel looked closely. In a second or two, Rosie started playing it. Mabel was wide-eyed as she looked how Rosie played the bass guitar. When she plucked closer to the bridge, the string produces more pronounced harmonics, giving a brighter tone. Then she move closer to the middle of the string that harmonics are less pronounced, giving a more mellow tone.

Mabel was completely mesmerized by the notes of the music that she had already dwell into a daydream. Unfortunately, a narcissistic voice rocked her back into reality. She spun around and her heart sank. No, no not these guys!

Heather grinned at her menacingly with crossed arms. "Hey, we want to say good job for killing that cat yesterday. We've never expected that you're a cat killer!"

Tears welled in Mabel's eyes. Stephanie joined in. "Yeah, wanna join our group? We've created a game that you will love. It's called Kill The Cats. The game was just simple. If you break the windows, you got three points. If you injured a cat, you got five points but if you killed a cat, you got ten points! So care to join?"

Mabel was about to speak when a blonde-haired girl stood in front of her. "No freakin' way!" Mabel was surprised. "Pacifica?"

Brianna gave the blonde a fierce frown. "Who told you to interrupt our talk? We just asking her if she wanted to join our group!"

"Into a group of imbeciles? Sorry, no chance!" Pacifica spat angrily. Chloe rolled up her sleeve. "Do you want to have a fight with us?!"

Mabel pushed Pacifica aside. "Guys, just stop! I've had enough!"

The gang and Pacifica stared at her. Mabel exhaled slowly. "Just leave me alone!" She quickly turned her heel and walked off, tears spilling from her eyes as she left the hallway. Pacifica called after her. "Mabel, wait!"

Heather and the gang shouted to her. "Scaredy-cat!"

Outside the school, Mabel ran with speed until she came across with her brother. Dipper looked worried. "Woah, Mabel, what's wrong? What happened?"

Mabel calmed herself, ignoring the pain of her muscles. She wasn't sure she could talk, but if she do, she thought she will fell sick. She glanced up to her brother. "Nope! There's nothing happening!" She said cheerfully, trying to look at the bright side of things. Dipper frowned. "Then, why are you running?"

"I'm running from a bird who is trying to eat my hair!" Mabel perjured, grinning with a cheerful face and hoping that her brother wasn't suspicious. But Dipper seemed to take that as an exception. "Oh well. Let's just go home."

Mabel grabbed his shoulders, stopping him. "Wait Dipper! I think I found our new band member!" Dipper turned to her. "Woah really? Who is it?"

She quickly exclaim, "Rosie Redwood!"

Dipper widened his eyes. "What?! No, no! Not Rosie!" Mabel frowned in confusion. "Why not?" Dipper leaned close to her and whispered. "Mabel, don't you know her? She's the most mysterious person in this school. I heard that she never talked to anyone before but she only asked them about subjects and homework. I even saw her eating along in the cafeteria!"

Mabel shook her head, denying everything of what her brother said about Rosie. "No, Dip. You're so wrong and what you said is wrong! It's no good judging people of their looks and their behaviour. What if she's just a helpless girl? Maybe she have a hard time socializing with people or she was only just shy. Do you think you have enough evidence to prove that she's creepy and all whatever that stories told about her? Everyone may think she was creepy, but overall she was not! These guys should be ashamed of themselves! And you too, bro-bro!"

Dipper indeed felt ashamed. He rubbed his arm. "Well, I think I was going too far. So, can you give me reasons why it was supposed to be her?"

"Well, she's talented! Seriously, she is!" Mabel explained. "I just saw her playing the bass guitar in the music room and poof! She's amazing. I think she's the one!"

"But don't you think we should ask her if she want to? Some people may reject the offer." Dipper expound. Mabel placed a finger on his chin. "Yeah, you're right." But luckily, she caught a sight of Rosie walking on the pavement close to them. 'Well here's she is now!"

Rosie was silently walking on the pavement when all of the sudden, Mabel jumped right in front of her. "Haiyo, Rosie!" She exclaimed. Rosie raised an eyebrow. "Uh… hi?"

"I just want to ask you that… would you agree to join us?" Mabel offered. Rosie was confused. "Sorry. I don't understand what you're talking about."

Dipper facepalmed. "Mabel! Give her details of the band!"

"Oh right." Mabel turned to Rosie. "Well, we're just about to form a band and we need a bassist. Who knew that I heard someone here is a bassist and that is you!"

"O-kay." Rosie murmured. Mabel continued, "We had a shack that was about to lose forever and the only way to save it is to form a band. 'Cause bands are rich right? So I was suggesting that, could you pwease help us? We need you to be our bassist! Please! Do you accept our offer?"

There was silence.

Mabel waited for her answer, which took her for several minutes. Dipper was uncertain and he bit his lip hard. Mabel was scared and worried. She would be jumping around if she said yes but her heart would be crushed if she says no.

Then, the answer they were hoping finally spoken. Rosie nodded. "Yeah, sure."

A/N: There you go guys! Sorry again that I took a very long time. And also New Year is closer! Yippee! You want to know why I'm happy? Well, New Year brings new joy, new things, new surprises and everything new! So Happy New Year guys! I'll see you all very soon!
