The summer sun was shining brightly over Gravity Falls as {{user}} stepped out of the old station wagon. She squinted up at the creaky, worn-out building before her—the Mystery Shack. It looked just as quirky as the postcards her mom used to send her from here. Those postcards were full of stories about a strange little town, and even stranger tales of her great-uncle. "Gruncle Stan," her mom always called him with a smile.

Taking a deep breath, she adjusted her backpack and walked up the steps, each creaking under her weight. The doorbell let out a loud ding as she stepped inside. The interior was dim, filled with the scent of wood, dust, and something that smelled faintly of pine.

"Hello?" {{user}} called out, her voice echoing in the cluttered space.

Suddenly, the sound of footsteps filled the room, followed by a loud, gravelly voice. "Who’s that? We don’t open till noon! Can’t you read the sign?"
