Happy birthday Pines twins!
"Today's the big day!" Mabel cheered. "Happy birthday bro!" She said as she bear hugged Dipper.
"Can't...breathe..." Dipper wheezed.
Mabel let go. "Sorry Dip! I'm just so excited! We're finally 18!"
"Not until 5:30." Dipper said. "5:35 for me." He muttered.
"I am the alpha twin after all!" Mabel cheered. "I'm gonna wear my favorite sweater!"
"Yeah, yeah." Dipper handed her a box with holes in it. "Happy birthday Mabes."
Mabel opened it and shrieked at the contents. "A KITTEN! AND EXTRA SUGAR PACKETS! THANK YOU SO MUCH!"
"No prob Mabel." Dipper said.
"I'm naming him Aoshima!" Mabel said, cuddling the kitten.
"Aoshima?" Dipper questioned.
"Don't ask." Mabel said. "Lemme get your gift!" She said running upstairs. She came down with a box. "Here!"
Dipper opened it and pulled out a sweater. It read "Little Dipper" and had a picture of the little dipper on it. "Wow Mabel this is...great!" He said. "Now I have something else to wear when it's cold."
"And I also got you this." Mabel said taking out something from behind her back. It was a book that had a picture of 6 fingers on it with the number 4 in the middle. "It's empty, but you can record your own findings in it." Mabel said. "I hope you like it!"
"Mabel..." Dipper said taking the book. "This is the best gift ever! Thank you!" He said hugging her.
"So, let's have a twin's day out! Just you and me bro-bro!" Mabel said.
"Done." Dipper said as they both walked out of the Shack.
"That was awesome!" Dipper cheered.
"You've got to write about it in the journal." Mabel said.
Dipper took out his journal. "Forest Fairies." He said writing it down. "Little green fairies that live in the Gravity Falls forest. They seem harmless but don't make them angry. They can join together to form a huge fairy. A lot like the gnomes. Weakness: Hair Dryers." He said finishing the entry. "I'll glue in the picture later."
Mabel took out her hair dryer. "And if any of them come near us I'll dry their hair!"
"Ok Mabel you can put that thing away." Dipper said. "Why did you have a hair dryer on you in the first place?"
"Oh I don't know. I have a lot of random things on me. Like sugar packets, gummy bears, a pumpkin, some illegal fireworks." Mabel said.
"Illegal fireworks?" Dipper questioned.
"Once again, don't ask." Mabel said.
"So, are you ready for our party?" Dipper asked.
"Yep! It's almost 4:00!" Mabel said. "Let's get ready! Insert getting prepared montage here!"
"Really Mabel?" Dipper said.
They both rushed to get ready. Mabel combed her hair (barely), put on some nacho earrings, out on her purple headband, and slipped on her shooting star sweater. "I'm ready!" She cheered.
Dipper went in the bathroom and spent 30 minutes doing his hair. "Dip! Are you done in there?" Mabel asked.
"Nope! My hair has to be perfect! Pacifica will be there!" Dipper said. As soon as he realized what he had said he slapped his hand over his mouth. "I mean, it's my birthday so it has to be perfect."
"OMG!" Mabel shrieked. "Ok! Take all the time you want!"
Dipper walked out of the bathroom. "I'm done."
Mabel looked at him and pushed him back into the bathroom. "It's time for a makeover!"
Mabel ruffled his hair. "It's perfect!"
"Mabel you totally messed it up!" Dipper shouted.
"But it looks better that way." Mabel said as Dipper looked in the mirror.
"You know...you're actually right." Dipper said. "Thanks Mabel."
"No prob bro! Now get out of the bathroom." Mabel said shooing Dipper out of the bathroom.
Dipper changed into a plain, white t-shirt with black pants. Then he put on his pine tree hat. "Perfect."
Pacifica looked at the dresses she had on her bed. "Is this too formal?" She asked herself.
She decided to go with a sweater-dress that kind of looked like the dress she wore on Pioneer Day. She combed her hair and put on a pair of boots, not bothering to put on makeup.
"Perfect." She said walking out the door.
The music was a little too loud for Dipper. Mabel had suggested turning the music up to the max volume. Also, Robbie had come and ruined Dipper's whole day. And finally, his parents didn't even show up. So instead of partying out with the rest of Gravity Falls, Dipper was sitting in his room reading journal 3.
There was a knock on the door.
"Come in." He muttered as he hid the journal.
"Hey bro." Mabel said. "Why aren't you out there partying?"
"It's too loud." Dipper said taking the journal back out.
"I'll turn down the music." Mabel tried.
"Robbie's down there." Dipper muttered.
"I'll kick him out." Mabel said.
"Mom and Dad are nowhere to be seen." Dipper said burying his face in the journal.
"Um...I'm sure they're just running late." Mabel tried.
"I'm gonna stay up here for a while. Have fun." Dipper said.
"Ok." Mabel said as she left.
After a while, there was another knock.
"Mabel can you please just leave me alone!" Dipper shouted.
Pacifica walked through the door.
"Oh, sorry Pacifica. I thought you were Mabel." Dipper said.
Pacifica took out a piece of paper. She looked at it for a while then crumpled it up and shoved it in her pocket. "Come on." Pacifica said. "Let's go dance." She said in the most calm and comforting voice ever.
"But...I really don't feel like it." Dipper argued.
"Please. For me?" Pacifica asked.
"But...fine." Dipper said, getting up from his bed.
Pacifica took his hand and led him downstairs. "Why are you up there all alone anyways?" Pacifica asked.
"Had a bad day." Dipper explained.
"On your birthday?" Pacifica questioned. "Let's fix that. Let's dance!"
They started dancing to Soos's music when suddenly it slowed down.
"This one goes out to all you dudes with a special someone." Soos said into the microphone.
Dipper and Pacifica stood there awkwardly for a moment.
"So...you wanna dance?" Pacifica asked.
"S-Sure." Dipper stuttered.
And so the two danced.
"Dipper, I've been meaning to tell you this for a while but...I really like you. Like, like you, like you." Pacifica said.
"R-Really?" Dipper asked.
"Yeah." Pacifica said.
"M-me too." Dipper stuttered.
"Really?" Pacifica said.
"Really." Dipper replied.
"Yes!" Pacifica said as she tackled Dipper in a hug.
"Woah! Haha!" Dipper said as he regained balance.
They stared at each other for a moment before slowing leaning in.
Their lips almost touched, but blue flames surrounded them and they were gone.
5 minutes earlier
Mabel was dancing with Candy and Grenda.
"This is the life girls!" Mabel cheered. "If only Dipper were here."
"Yeah." Candy said. "That would be much better."
Mabel saw something out of the corner of her eye. She spun around.
There was Bill.
Mabel stared at him in shock as he stared back. He had a sad look in his eyes.
"G-girls...I'll be right back." Mabel said as she walked towards Bill.
Once Bill saw her, his eyes widened and he walked away. "Bill wait!" Mabel shouted.
He walked out the door.
Mabel chased after him. "Bill where are you going?"
He kept running.
"Come back!" Mabel shouted.
"It's 5:35! That means Dipper and Mabel are officially 18!" Stan's voice could be heard from the Shack.
Bill stopped and turned around.
"Bill!" Mabel shouted in relief. "You came back."
Bill sighed.
"Bill?" Mabel said. "Bill are you okay?"
Just as Mabel was about to hug him, blue flames surrounded them both.
Mabel looked at her surroundings.
"W-what happened?" She asked.
"Mabel? Is that you?" Dipper's voice came out of nowhere.
"Dipper? Yeah I'm over here!" Mabel said.
Dipper and Pacifica came out of the shadows. "Mabel!" Pacifica said. "Where are we?"
"I have no idea." Mabel replied.
Suddenly, Stan, Soos, Robbie, and Wendy appeared in front of them.
"What is he doing here?" Dipper said pointing at Robbie.
"I don't even know why I'm here." Robbie said.
Gideon and two other men appeared in front of everyone.
"Gideon?" The twins said.
"S-Stanley?" Stanford stuttered.
"Old dude?" Pacifica said.
"Stanford?" The man who was named Stanley said. "W-why are you here?"
"I don't know but it probably has something to do with-"
"With me." Stan was cut of by a voice in the shadows.
A triangle floated out of the shadows.
"I brought you here."
DUN DUN DUN!
