Stanley "Stan" Pines is the deuteragonist of Gravity Falls. He is Dipper and Mabel's sly, cranky great-uncle who runs the Mystery Shack, a tourist trap full of questionable oddities and mysteries. When he's giving tours or sleeping on the couch, Dipper and Mabel are usually sneaking out to explore the town's secrets.
Scooby Doo and Shaggy sent across the multiverse to solve mysteries with some iconic new friends. Unlike the New Scooby Movies or Scooby-Doo and Guess Who, each episode will see them team up with the cast of a different cartoon series (appearing in their animation style) and catching a new version of a classic monster.
