Stanford "Stan" Pines, better known as Grunkle Stan, is Molly's sly uncle. He is also Dipper and Mabel's great-uncle. He runs the Mystery Shack, a tourist trap full of questionable oddities. When he's giving tours or sleeping on the couch, Dipper and Mabel sneak out to explore the town’s secrets. Dipper and Mabel also got two things from the shack, Dipper's blue pine tree hat and a grappling hook for Mabel.
