Season two of Disney's popular animated comedy series "Gravity Falls," starring Jason Ritter ("Parenthood") and Kristen Schaal ("The Daily Show with Jon Stewart") as Dipper and Mabel Pines, twins who spend the summer with their eccentric Great Uncle Stan (aka Grunkle Stan), debuts FRIDAY, AUGUST 1 (9:00 p.m., ET/PT) on Disney Channel and MONDAY, AUGUST 4 (9:00 p.m., ET/PT) on Disney XD. Thereafter new episodes will debut on Disney XD with subsequent airings on Disney Channel.

"Gravity Falls" creator and executive producer, Alex Hirsch, announced the season premiere during the "Gravity Falls Live!" panel at the Los Angeles Film Festival on Saturday, June 14.

The new season finds Dipper and Mabel digging deeper than ever to learn the secret history of Journal #3's unknown author, while Stan (voiced by Hirsch) works on a secret project that could change everything in the basement of the Mystery Shack. Scarier creatures, weirder magic and new hilarious characters, including vengeful villains and love interests, will be introduced. Upcoming guest stars include Mark Hamill (Luke Skywalker in Star Wars Saga) and Patton Oswalt (ABC's "The Goldbergs"). Throughout the season, unique puzzle pieces with secret decodable messages will be revealed at the end of each episode's credits.

The season premiere episode, titled "Scary-oke," finds the Pines family resolving to get back to normal after the Lil' Gideon incident. They throw a "Mystery Shack is Back" party, but some unwelcome guests crash it. In the second episode, "Into the Bunker," premiering exclusively on Disney XD, Dipper's secret journal pages lead him and the gang to the author's hidden bunker where they find themselves face-to-face with a mysterious figure from Gravity Falls' lore.
