It had been another quiet, peaceful and normal afternoon in the Mystery Shack.

Stan Pines, the owner of the shack and the summer caretaker of his great niece and nephew, Dipper and Mabel Pines, who had come to stay with him at the shack for the summer, was happily humming and counting the money he had earned from his last tour at the register, when Dipper, Mabel and his handyman, Soos entered into the room excitedly.

"GRUNKLE STAN! WE ARE GOING TO GET SOME ICE CREAM AT THE DINER!" Mabel told her grunkle happily as she ran past him.

"Now? Today? BUT IT'S A WORK DAY!" Stan frowned, his happy mood vanishing as he looked up at them sternly.

"Don't worry, Grunkle Stan, we won't be gone long," Dipper reassured his grunkle. "We'll be back before you know it!"

"Alright enough talk, dudes! Who's ready for some ice cream?" Soos asked excitedly.

"WE ARE!" Dipper and Mabel screamed excitedly.

They all chanted "ICE CREAM! ICE CREAM!" as they ran out of the shack and went off into the distance.

Stan sighed and shook his head in disbelief as he went back to counting his money. He couldn't believe that the kids and Soos had all went off to get ice cream on a work day. A WORK DAY. SERIOUSLY. HOW CAN THEY THINK THAT ICE CREAM IS MORE IMPORTANT THAN GETTING MONEY?! he asked himself angrily.

His thoughts were interrupted when his brother, Ford Pines, who he had recently saved from the portal, rushed past him, carrying many technical equipment in his hands.

"Whoa. Where are you off to, Sixer?" Stan asked him.

"I'm going to do a bit of research," Ford told him. "I'm going to find out why an alien craft had came to Gravity Falls!"

"Oh, well have fun, then," Stan told him. "now if you'll please excuse me, I got some money to count!"

Once Ford had left, Stan began counting up his money again. He grinned at the load of cash in his hands. "Boy, those tourists will fall for anything," he chuckled to himself.

Suddenly, a tall thin girl with blond hair, a pink shirt and black pants had entered the shack. "Excuse me, sir."

Stan looked up and his eyes widened when he saw her. She was one of the prettiest girls he had ever saw…. and she looked so familiar to him… he felt as if he met her somewhere before….

Stan brushed the thought away. Now wasn't the time for his mind to interrupt him from scamming another tourist. A pretty one, in fact. He cleared his throat and gave the girl a big smile. "Welcome to the Mystery Shack, ma'am!" he announced happily. "What can I get you?"

The girl giggled as she walked up to Stan. "What I need right now is very simple…..YOU!"

Stan looked very confused. "Wait-what do you mean by-"

That was all he could say before the girl unleashed her spider fangs and bit into Stan, knocking him dead unconscious with her venom.

The girl smiled an evil smile as she dragged Stan out of the shack and into the distance.
