Gravity Falls, Oregon is the soul and heart of many peculiar creatures. Located in its woods was a demolished building known as the Mystery Shack. Hosting many eccentric attractions, business critically flourished, resulting in its astonishing popularity. One day, however, the shack mysteriously vanished along with their employees.
The only one who remained unharmed was a 13-year-old boy named Dipper.
