Smith Dee Bradley Baker Mark Bodnar Dee Snider Kath Soucie Steve Blum Brook Chalmers Valery Pappas Clancy Brown Broadcast and reception Secret Mountain premiered on August 1, 2011, on Cartoon Network as part of a sneak preview; this broadcast was seen by 1.8 million viewers. It premiered formally on September 26 as part of their Monday night programming block, where it was seen by 1.3 million viewers, marking a slight decrease from the previous broadcast. The show was moved to Fridays upon its second-season premiere on December 30, 2011. Following the premiere of the eighth episode of the season on February 17, 2012, the show was pulled from broadcast. The network released the remaining eight episodes through iTunes a month later, from March 8 to March 29, thus concluding the show. Many critics were complimentary in regards to the series' art style. In his website Lineboil, Aaron Simpson compared it to Garbage Pail Kids and the works of Don Martin, two elements of his childhood. Amid Amidi of Cartoon Brew called Robertryan Cory's character designs "impressive" and "distinctively styled", though he felt the art style's complexity made the limited animation quality suffer as a result. Abby Koenig of Houston Press compared its "ridiculous" nature to the film Little Monsters, and proposed that Howie Mandel (featured in the latter work) guest voice a monster on the show. Shannon O'Leary of Publishers Weekly wrote that the show, along with others on the network such as Adventure Time and Superjail!, bore resemblance to the aesthetics of established independent comics artists. Meanwhile, Jason Krell of io9 considered it a failure despite its influences from Adventure Time, which made way for many successful original series on the network. The episode "Nightmare Sauce" received multiple accolades, including at the 2012 Annecy International Animated Film Festival for "Best TV Production" (of which Browngardt was the recipient), and at the 64th Primetime Emmy Awards, where Cory and Chris Tsirgiotis were awarded "Outstanding Individual in Animation". Cory also won at the 39th Annie Awards for "Character Design in a Television Production", while Tsirgiotis, Sue Mondt, Daniel Elson and Mark Bodnar were collectively awarded "Production Design in a Television Production". At the 40th Annie Awards, Thaddeus Paul Couldron was nominated for "Character Design in an Animated Television or Other Broadcast Venue Production" for his work on the episode "Secret Mountain Uncle Grandpa".
