Gravity Falls Merchandise Welcome to Gravity Falls, Oregon! Come explore with all your friends. You can expect to walk around here wearing that. Why don’t you try on Gravity Falls t-shirt that will fit just right? It sure can get cold here at night. Stay warm with a Gravity Falls beanie or hat just like the one Dipper is wearing. Things are getting pretty weird here. Better stop by Grunkle Stan’s The Mystery Shack and see what Gravity Falls merchandise he has that will help. Thanks for stopping by! Be careful not to walk into any portals on the way.
