Dipper giving Mabel that surprise party she always wanted for her 15th birthday complete with floating cakes and presents.
MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
Happy birthday not only to Mabel and Dipper, but also to me ;3
Mabel was hanging out with Pacifica the whole time. They were hanging out at the minigolf course, playing a game with a few of the local gnomes when Pacifica's phone buzzed. She pulled it out, checked the text she had gotten, and gasped.
"Mabel, we need to go."
"What do you mean?"
"I mean we need to go, now. Grenda just texted me saying that there's some kind of Pro-Natural rally going on at the Shack and we need to be there ASAP." Pacifica stowed her phone away in her track jacket pocket and handed her club to Jeff. "You mind finishing this game without us?"
"Not at all! We'll beat those Lilliputtians at their own game!" Jeff slung the putter over his stubby shoulder, knocking Schmebulock unconscious.
"Hey!" One of the Lilliputtian people poked their round heads from their hiding spot and shook their fist. "I take offence to that!"
"Good!"
Pacifica grabbed Mabel's hand and dragged her from the minigolf course as fast as her legs would allow, hopping in the Mystery Cart and speeding off toward the Shack. The somber expression on her face worried Mabel; normally the blond girl was much more robust and lively than this, but to see her face drawn and pale meant something big was going down and, despite her parents being big icons in the Pro-Natural world, she was an avid supporter of equal rights. If she was worried, that meant something big was going down. But where was Dipper?
They arrived at the Shack to see a large crowd of people in brown hooded cloaks--a-la the KKK--shouting "Preters go home! Leave us alone! Back to Hell on your side of the Veil!" Mabel swallowed heavily as she watched Stan holding his special Stan-bat and swinging it at anyone who got too close.
"Mabel," he cried when he saw his niece arrive with her friend, "Get inside!"
"But I can help," she cried out, fighting her way through the Pro-Natural crowd.
"Don't bother; they're not going to listen to reason! Just get inside and get safe!"
"Where's Dipper?"
"He had a summons to attend to but don't worry, he should be back any moment from now and then the two of you can handle this mess." One of the Pro-Naturalists tried to get to the door but Stan shoved him off the porch and back to with his friends. "Now go!"
Mabel and Pacifica dashed inside and closed the door, greeted by pitch blackness. Confused, Mabel fumbled around for the light switch and, upon finding it, turned on the lights.
When her eyes adjusted, she was greeted with a loud "Surprise!"
Inside the Shack was everyone she loved, all smiling at her, with a large birthday cake floating in the air in front of them. McGuckett, Grenda, Candy, Wendy, Tambry, Nate, Lee, Thompson, and Robbie were there. But Dipper wasn't there and Grunkle Stan was still fighting off Pro-Naturalists....
Speak of the devil, the door behind her opened and Stan came in, followed by a floating and very smug Dipper. Behind them was no indication that Pro-Naturalists had ever been there. The front yard was completely empty.
Tears welled in Mabel's eyes as she took in the sights and sounds of her very own surprise party."You did this for me? Without me knowing?"
"Sure," Pacifica shrugged. "It was a lot easier than you'd think. Especially with my pro acting skills."
"I figured if I had omniscience that I may as well use it for something good." Dipper said, smiling down at his sister. "Happy birthday Mabes."
"But Stan said you had a summons."
"Technically not a lie," Stan grinned and shouldered the Stan bat. "I summoned him and struck up a deal for this whole business with the 'Pro-Natural' rally." He finger quoted around Pro-Natural, making Mabel giggle.
"So how does your first surprise party feel?" Dipper leaned in and ruffled her hair. "Everything you ever wanted?"
She shook it off and laughed, a deep sound from the very core of her being. "And more. Happy birthday to you too Dippingsauce."
