Disney released a new parody video to promote the long-awaited Gravity Falls: Journal 3 book. The video stars the actors who voice the Pines twins, Kristen Schaal America’s sweetheart (to a small few) and Jason Ritter. In the quirky segment, the Dipper and Mabel actors sell an actual book “sweater” to fans.

Last year, the final episode of the beloved Gravity Falls series aired; but that doesn’t mean the mysteries from the Oregon town ended with it. Disney is releasing a new book called Journal 3, which is filled with new monsters, secrets and notes from Dipper and Mabel for fans to explore. The 288-page full-color hardcover book is accompanied by a book jacket, which doubles as an exclusive poster. Fans can purchase the book here.
