Enter the Shack

You pay up $20 to the scratchy-voiced man, who is rather old, and is wearing a nice black suit with a red bolo tie and a fez of the same color, with a curios symbol on the front – Shriner, maybe? He’s also wearing an eye patch over thick square glasses.

The man winks at you, you assume, and chuckles. “You won’t regret it, pip-squeak!”

Facing back to the crowd, he introduces himself as Mr. Mystery and then launches into an introductory spiel about the “eighth wonder of the world” that is Gravity Falls. He leads you into a large front room to the first exhibit, pulling the curtain off with great fanfare.

While he's addressing the crowd, you see a door marked "Employees Only" that is standing ajar.

Sneak through the door while he's distracted.

Listen to the exhibit.
