This is a list of episodes for "Uncle Grandpa", an American animated TV series created by Peter Browngardt and airing on Cartoon Network.
 The pilot episode was created in 2008 but was aired on Cartoon Network Video in 2010 as part of the show project "The Cartoonstitute", while the series premiered on September 2, 2013.
 On July 25, 2014, the series was renewed for a second season, which premiered on March 5, 2015.
Peter "Pete" Browngardt (born August 12, 1979 in Sag Harbor, New York) is an American animator, writer, voice actor, and producer, who is best known for being the creator of Cartoon Network's "Uncle Grandpa", in which he also voices the title character, and its early spin-off "Secret Mountain Fort Awesome".
 Browngardt has had prior experience working on shows such as "Futurama", "Chowder", and "The Marvelous Misadventures of Flapjack".
 His main contribution to the "Adventure Time" series is storyboarding and writing the episode "Wizard".
"Adventure Time" is an animated short created by Pendleton Ward, as well as the pilot to the Cartoon Network series of the same name.
 The short follows the adventures of Pen (voiced by Zack Shada), a human boy, and his best friend Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will.
 In this episode, Pen and Jake have to rescue Princess Bubblegum (voiced by Paige Moss) from the antagonistic Ice King (voiced by John Kassir).
Secret Mountain Fort Awesome is an American animated television series created by Peter Browngardt that debuted in 2011 on Cartoon Network.
 The show revolves around a fraternity of five monsters who unleash wild stunts upon the public from their eponymous mountain fort.
 The show is loosely based on the antagonists that appeared in Browngardt's animated short, "Uncle Grandpa", and employs Mike Conte of the heavy metal band Early Man as composer.
The first season of American animated television series "Regular Show" originally aired on Cartoon Network in the United States.
 Many of the characters are loosely based on those developed for J.G. Quintel's student films at California Institute of the Arts: "The Naïve Man From Lolliland" and "2 in the AM PM".
 Quintel pitched "Regular Show" for Cartoon Network's Cartoonstitute project, in which the network allowed young artists to create pilots with no notes to possibly be optioned as a show.
 After being green-lit, Quintel recruited several indie comic book artists, plus some of the crew members he had worked with on "The Marvelous Misadventures of Flapjack", to compose the staff of the show, as their style matched close to what he desired for the series.
 "Regular Show" was picked up by Cartoon Network, who decided to create a twelve-episode first season.
"Secret Mountain Fort Awesome" is an American animated television series based on the cartoon short "Uncle Grandpa" created by Peter Browngardt.
 The series aired on Cartoon Network in August 1, 2011, and produced 26 episodes over two seasons.
The Cartoonstitute was a planned Cartoon Network project created by Cartoon Network's executive Rob Sorcher that would have been a showcase for animated shorts created without the interference of network executives and focus testing.
 It was headed by Craig McCracken (creator of "The Powerpuff Girls", "Foster's Home for Imaginary Friends", and "Wander Over Yonder") and Rob Renzetti (creator of "My Life as a Teenage Robot").
 39 shorts for the project were in development at Cartoon Network Studios, but only 14 of these were completed.
 Eventually, balancing 5 upcoming shows and adding another proved difficult and the project was scrapped.
 Of the shorts which were made, only "Regular Show" and "Uncle Grandpa" have been greenlit to become animated series (the latter was initially greenlit as "Secret Mountain Fort Awesome", before becoming a series of its own).
 On May 7, 2010, Cartoon Network uploaded nearly all of the shorts to their website.
 The only shorts not uploaded were "Maruined", "3 Dog Band", and "Joey to the World".
