Fandom: Gravity Falls & Star vs the Forces of Evil

When he and his twin sister Mabel went back to California at the start of the school year, Dipper Pines was convinced that was the end of the craziness. Surely, they would be leaving all weirdness and bizarre mystery adventures back in Gravity Falls… Nope.

It looked like things would be normal, when they started the first day of school. Just the same ‘ol boring routine for the next nine months – wake up at the unholiest of hours, drag butt to class, struggle to stay awake for the rest of the day while listening to teachers drone on and on, eat the mediocre school lunch, finish classes, then go home.

Then, Mabel introduced him to her new friend, and everything began looking up…

Mabel was sitting in class, her big wool cat sweater's sleeves covering her hands, as she rested her head on her desk. Her thick, brown hair flopped over her eyes, her pink head band that matched her sweater drooping slightly.

She was suppose to be solving the math problems on the worksheet the teacher had passed out earlier, but they were much too difficult.

It was way too early for dumb smarty nerd classes for poop heads. Algebra hurt her head! Too many numbers and boring word problems. She didn’t even have Dipper to make the class more bearable, because he was in a more advanced math class.

Which was completely ridiculous and unfair! She and Dipper had shared every class together since kindergarten! How could they split up now? It didn’t help that this had been exactly what she’d been afraid, why Bill had managed to keep her trapped in that fake paradise bubble and… Mabel shook her head. She’d rather not think about that. The point was: so far freshman year of high school sucked.

Mabel wished it was time for her art class already! That would have been much more interesting. She groaned, only to be shushed by the person sitting next to her. (This only prompted her to stick her tongue out at them.)

As if the universe were answering her internal pleas for something exciting to happen, a girl burst through the door with a huge grin on her face. Her big, blue eyes twinkled with an enthusiasm that only Mabel's own optimistic attitude could rival with.

The girl's thick, golden blonde hair flew behind her as she pranced around the room with the energy of a small child running through a toy store. She was dressed in a long green dress that went down to her thighs and had a rainbow on the front of it, colorful leggings covering her legs. Her head band had little horns on the top, and her knee length boots had pictures of bunnies on them.

Mabel looked up, taking in the other girl's appearance in just a few seconds before a broad grin formed on her lips. She could already tell they were going to get along swimmingly.

“Hellooo!” the blonde sang, waving at the bored faces of her class mates. A few people waved back, but other than that no one paid her attention, regarding her in much the same way they’d been doing with Mabel.

The teacher glanced up lazily from where she was perched at her desk. She sighed, looking utterly exasperated by the new presence. “Miss Butterfly, you are late.”

The blonde girl grinned sheepishly. She scratched the top of her head with the baby rattle looking thing in her hand. “I have a good reason for that. And that’s because I didn’t really want to be here.”

The teacher blanched in shock, and a few other students lifted their heads at the potential drama. The blonde girl shrugged, apparently not realizing that what she’d just said could be considered rude. “My new friend Marco tried explaining this stuff to me last period, and I gotta say it seems pretty boring.”

She slumped forward, forcing her voice to get deeper with the last two words, emphasizing her point with a dramatic flair. This got a few snickers from the other students, including Mabel.

The teacher flashed the girl an annoyed look. “Well, you’re here now so if it’s no too boring for you, you can have a seat next to Miss Pines in the back.” She sent a curt nod Mabel's way, and the brunette perked up. She sat on her knees, waving excitedly at the potential new friend.

The blonde grinned back, waving rapidly in return. She charged down the isles at a full on sprint, her hair flapping against her back. The girl pressed her hands against Mabel's desk as she reached her; and Mabel jumped up, practically standing on top of her desk. She held her hand out to the girl. “Hi, I’m Mabel!”

“Star Butterfly!” The blonde, Star, shook her hand vigorously before flopping down into the seat on the other side of Mabel. She pressed her hands to her cheeks, stomping her feet repeatedly on the floor. “Oh my goodness, I love your sweater!!!” 

Mabel grinned even wider, as she quickly sat back down in her seat properly, turning to face the other girl. “Thanks! I knitted it myself!”

Star gasped, letting out squeal and getting some rather estranged looks from those around them. “Do you think you can make me one, too?”

Mabel shrieked happily. “Yes! I would love to!” The two girls giggled together, as the teacher shot them and annoyed look, warning them to be quiet. They didn’t listen. Mabel examined the other girl’s cheeks with a squeal of excitement. “I adore your heart cheeks! They are so cute!”

Star poked her cheeks, smiling widely. “Thank you! They’re my Mweni markings. I’m a princess. From another dimension…called Mewni.” She held up the rattle thing. “And this is my magic wand!”

Mabel gasped, taking in the wand's appearance more clearly. It was pink and white with a golden star at the center and wings on the side. She squished her cheeks, eyes sparkling with wonder. “It's beautiful,” she whispered. Then, she thought of something. “Wait, did you say magic? Can you do a spell?”

Star nodded enthusiastically. She raised her wand high into the air, shouting, “Rainbow, kitty, glitter!”

A colorful blast shot out from her wand, flying into the air before erupting into a burst of kittens and rainbow colored glitter. The class sat up, some people looking annoyed but most of them cheering and laughing, happy for something that didn’t have to do with nerdy word problems.

Mabel let out another excited squeal, flopping down on to the floor and making glitter angels. She giggled as the kittens padded up to her, rubbing their little heads against her. Mabel sat up and pet them. “I love them!”

“Miss Butterfly, you are disrupting my class,” the teacher scolded angrily.

Star shrugged. “Sorry, but look!” She pointed at the students. “It's making them happy!” The teacher was not amused.

Mabel stood up, gently placing the kittens on the ground as she did so. She had suddenly thought of something else. “Hey, you’re from another dimension? That sounds like one of those nerd things my brother Dipper and Grunkle Ford are into.”

She remembered Grunkle Ford had accidentally fallen into a portal thanks to a fight he had with his brother Stan, and he had been stuck traveling through other dimensions until Stan was able to rebuild the machine and bring him back to their dimension thirty years later. (Mabel had been there when it happened. It was seriously wack.)

Star tilted her head to the side, frowning thoughtfully. “Ford? My parents knew someone called Ford too! He had six fingers.”

Mabel gasped, waving her arms around wildly. “Oh my goodness! That sounds like my Grunkle!!”

“Really??” Star gasped herself.

“Miss Butterfly. Miss Pines,” the teacher scolded. They ignored her, completely enthralled by their conversation.

“I bet Dipper will be so excited to meet you!” Mabel said.

“Why wait?” Star said. She grabbed Mabel's hand, running out the door and down the hall way. “Let’s go find him!”

Yee, sorry. I keep starting new things without finishing other stuff. But lately I’ve just been…meh with live action shows. I’ve been in such a cartoonish mood so…here we are! Something to do between chapters of my main projects.

This idea has been in my head for awhile now, and maybe later I might make it into a big project, like one some of my others finish up. A crossover with Gravity Falls and Star vs the Forces of Evil.

I found a theory on YouTube that they’re in the same multiverse, and I thought…hm. What if the Pines Twins ended up in the same high school with Marco Diaz and Star Butterfly! I figured Star and Mable would be fast friends, their energetic personalities feeding off one another.

If y’all want I can do a part two and three where 1) Mabel introduces Star and Dipper and 2) Marco and Dipper meet each other
