Premise and format Edit
Uncle Grandpa, the magical uncle and grandpa who is the uncle-grandpa and brother-dad of every child and adult in the world, stops by children's houses every day to see how they are doing. The children he visits have a problem of their own and Uncle Grandpa tries to help them through a series of chaotic and surreal misadventures. He is a clowny sort of person who sometimes eats intangible objects (paper, and mostly books). He drives/lives in a recreational vehicle (RV) and is accompanied by a red talking fanny pack named Belly Bag, an anthropomorphic dinosaur named Mr. Gus, a photo cutout of a tiger named Giant Realistic Flying Tiger, and a talking pizza slice named Pizza Steve.
The show is a surreal action-adventure comedy that relies extensively on visual gags and catchphrases. Creator Pete Browngardt has cited the work of cartoonists Don Martin, Gary Larson and Robert Crumb, as well as Golden Age-era animators such as Tex Avery when it came to developing the style of the show. Each 11-minute episode is presented in a unique format, consisting of a main seven- to nine-minute story, some short bumpers typically composed of a quick visual joke, and an original short that focuses on the show's side-characters.
