Jellystone! is an American animated comedy web television series produced by Warner Bros. Animation for the HBO Max VSOD service premiering on July 29, 2021.[2] It is a spin-off from The Huckleberry Hound Show and The Yogi Bear Show, as well as stars from other Hanna-Barbera series.

In the town of Jellystone,[3] Yogi & Boo Boo lead an all-star cast of classic Hanna-Barbera characters, where they will "come together to live, work and play... but, at the same time, can’t help but stir up trouble for one another."[4] Some of whom will be Huckleberry Hound, Augie Doggie, Doggie Daddy, Ruff, Yakky Doodle, Shag Rugg, Jabberjaw, El Kabong, Top Cat, Captain Caveman, Cindy Bear, Mildew Wolf, Pixie and Dixie and Mr. Jinks, Peter Potamus, Snagglepuss, Magilla Gorilla.[5]



C.H. Greenblatt began development in February 2018, taking a year and a half to get the series approved, when it officially went into production in August 2019.[6] It was officially announced on October 29, 2019.[5] For the first few months, work began in the studio, although the crew was forced to work from home due to the COVID-19 lockdown. Despite not being halted, the production takes twice as long, because of direct contact in the studio being substituted with video chats and online screenings.[7]

Characters that won't appear in the beginning, may appear later on if the series goes on long enough.[8]

An official press release and trailer were unveiled on June 24, 2021.[2]


Jeff Bergman was announced to be voicing Yogi, among unspecified others, in September 2020.[9] The rest of Bergman's roles and further cast, such as Greenblatt voicing classic characters such as Boo Boo, were revealed on June 24, 2021.[2]
