Hey all! To the people following this story and have so far liked it, thank you so much for the support. I lost motivation to move this story over here from AO3 and even more so to improve on it. But I rewatched the series again and remembered why I wanted to even write this story in the first place. Im going to be changing the two chapters I have on here slightly and adding a lot more chapters to the original story. I want to really flesh out the relationship between my OC and the Stan twins. Again, thank you to every one who chose to follow my story and I hope you like the rest of this story.

I do not own Gravity Falls or any of the characters other than my OC.

Big fluffy white clouds moved lazily across the sky as a bird flew over the blue-green ocean. The waves licked the hot golden sand as a pair of bright green eyes stared ahead. A small red radio sat above her and the soft sounds coming from it blended with the sound of the waves and the occasional caw of a seagull. She had never seen a beach like this one before. She was so used to the foggy and loud harbor. She smiled. This was something she could get used to seeing.

She really should get down. The blood would pretty soon start rushing to her head and she would faint again. Like the last time at that playground in Central Park. But the world looked so different upside down. You got a whole new perspective of it. To her, the sky was gold and full of seashells. The ground was a vast blue blanket and was cut off by another light blue one covered in balls of cotton.

Pushing herself forwards, she swung her body slightly and watched as the world moved back and forth.

She gasped and stopped swinging when her emerald eyes met with a pair of brown ones. The girl fell off the red swing set bar and landed with a 'oof ' onto the sand.

"What were you doin' hangin' from the swings upside down?" The boy asked. She looked up at him and jumped slightly when she felt a tap on her shoulder. She turned around and her eyes met with another pair of brown eyes, the same as the other boy only these eyes were behind glasses.

"Do you need help getting up?" The boy wearing the glasses asked her.

She shook her head and stood up, dusting herself off, getting rid of the sand now on her shorts.

"Why were you hanging upside down?" The first boy repeated.

"I like hanging upside down." She answered. She finally got a good look at the two boys and blinked. At first she thought the rush of blood to her head was making her see double.

They were twins, she realized. The only difference was their clothes. The one with glasses wore a black jacket and white shirt and the other one wore a red and white striped shirt. He had a band-aid on his left cheek and was missing a tooth but other than that, they were identical.

"Why?" The first boy asked looking confused.

"Because I like looking at things that way." She said with a huff.

"You're that new girl right? I've never seen you at school before." The boy with the glasses said.

The girl nodded. "Yep. Just moved here. I'm from New York."

The twins looked at her in surprise and awe.

"Whoa! New York! That's so cool." The boy with the band-aid said with a grin.

She grinned at them. "My name's Catherine. Catherine Baez."

The one with the band-aid stepped forwards and with a grin introduced themselves.

"Well, I'm Stanley and he's Stanford." he said, jerking a thumb towards his brother who had his hands in his pockets and a small smile on his face.

She heard a voice yell out her name from behind them and she turned.

"Ya voy, Papá!" Catherine answered back. She turned back to the two boys.

"You speak Spanish?" Stanford asked and she blushed. Speaking that language wasn't something to be so proud of. Catherine looked at the ground.

"Uh, yeah. My dad is from Mexico." she said, looking at the ground.

She had hoped she didn't have to share this part of herself with the two people she had just met. It wasn't something her dad liked her talking about because of what the reaction would be.

Stanford saw her reaction to this and he frowned slightly. He was a smart kid. He had seen the news and reactions towards anyone different. He definitely knew how that felt and figured it wouldn't hurt to show her what made him different too.

A pair of hands were shown to her while her head was still down and she looked at them, her eyes widening after noticing the number of fingers. There were six on each hand.

"Ford, what the heck?" Stanley yelled but Ford had a determined look on his face.

"I was born with my hands like this. I don't like showing people my hands because of it but I think you can be an exception." he said. He sounded confident but he was really nervous. Catherine looked at his hands and then at him and then grinned.

"That's so cool." she said to him and he smiled. Stan looked at them and then shared their same smile.

"We should invite her on our mystery hunts." Stan said to his brother.

"Yeah, we should." Ford said and they heard the same voice from before calling out Catherine's name.

"Sorry, I gotta go." she said to them. "Can I meet you here again tomorrow?"

"Sure!" Stanley said to her and after they said their good-byes, Catherine grabbed her small red radio and raced over to her father.

"So, you made some new friends?" Catherine's dad asked her as he drove them back to their new house to finish unpacking.

"Yep!" Catherine said, cheerfully. "They're twins! Stanley and Stanford Pines!"

"That's great, sweetheart." he responded.

"Hey, papá?" she asked and he glanced over to her.

"Yes?"

"Can we go to the post office later? I need to drop something off." she said and her father sighed.

"Is it another letter for you mother?" he asked but he already knew the answer.

"Yeah. I wanna try again." she said. "Maybe this time she'll write back."

Her father parked the car into the driveway and turned off the engine. He turned to her, a sympathetic look on his face. He looked conflicted, as if wanting to tell her something difficult but he said something else.

"Uh, sure." he said and she smiled at him. "We can drop it off on our way to school, how's that?"

"Yeah!" she said, her eyes shining.

Her dad looked away for a moment and then turned back and faked a smile, but Catherine didn't notice. "Come on. Let's go finish up unpacking. If we finish fast enough, we start painting your room."

"Yay!" Catherine cheered and she hopped out of the car. Her father followed after her, now dreading the phone conversation he needed to have again with his ex-wife.

"Whoa! This is soooooo awesome!" Catherine said excitedly as she admired the big boat in front of her. It was missing the mast and parts of the sides were falling off but it was the first boat that she had seen up close so it was pretty cool. "You guys built this?"

"Well no. We found it in an old cave. But we dragged it out so we could fix it up." Stanley said, looking extremely proud. "We call it the 'Stan o' War'."

She nodded and put her hand on the side of the boat, feeling the smooth and somewhat damp surface.

"Can I...can I get on it?"

"Sure!" Stanley said happily and lifted her up. She gave a small yelp in surprise and her cheeks turned a light pink.

"Wow, you're really light." Stanley commented as he climbed in after her and Ford right behind him.

"Me and Stan are planning to use this to sail away and solve all sorts of mysteries!"

"Cool." Catherine said as she looked around the ship. "Can I come with?"

"Sure. The more the merrier!" Stanford said with a grin and fixed his glasses.

"Yeah!" Stan said as he put an arm around their shoulders and grinned at them.

They stopped grinning when they heard laughter behind them. They turned and found a group of boys, snickering at them.

"Well, this is a surprise." The tallest boy of the small group said. "Never thought you two would actually get a girl to talk to you. Much less get her onto your stupid boat."

Stan growled. "Shut up Crampelter!""

"What are you gonna do, Pines?" the boy sneered back. "You gonna make me?"

Stanley stepped forwards but Ford held him back.

"Stan, don't, he isn't worth it." he muttered quietly. The boys laughed some more and when they turned around to leave, a rock hit the back of Crampelter's head. He stopped and turned back around, a glare on his face.

"Alright, which one of you idiots did that?!" he yelled. Before either of the Pines twins could respond, Catherine stepped forwards and threw another rock.

"I did!" she yelled and the rock hit him right in the forehead. His head snapped back and he stumbled back. When he looked back at her, she lifted up a bigger rock and that convinced him to get the heck out of there. The other two boys with him shared a surprised glance and looked back at Catherine.

"Any one of you two gonna say something too?" she asked as she lifted the rock up again and they both flinched and ran off after their friend.

Stan and Ford both grinned when they saw that the group ran off and they cheered. Catherine blushed but grinned with them.

"That was so awesome!" Stan cheered and the twins pulled her into a hug. "I think that settles it, don't you think Ford?"

"Settles what?" he asked his brother with a small chuckle.

"That we are now the mystery trio." Stan said which made Ford roll his eyes at the name but Catherine laughed.

"We are not going to be called the 'mystery trio', Stanley." Ford said.

"Come on! It sounds cool." Stan protested. "Besides it makes sense because we're gonna be hunting monsters and solving mysteries together!"

"I think it sounds cool." Catherine said and Stan gave Ford a satisfied grin.

"See! Two against one. You lose, point-dexter!" Stanley said which made Catherine laugh some more. She was really starting to like New Jersey.
