UNCLE GRANDPA follows the exploits of Uncle Grandpa (voiced by Pete Browngardt) –- said to be the uncle and grandpa of everyone in the world -– as he travels around the world in an RV keeping tabs on kids and helping them solve their problems. He's joined by his trusty fanny pack, Belly Bag (Eric Bauza), holder of all things necessary in their adventures; Mr. Gus (Kevin Michael Richardson), the tough-talking dinosaur who's the muscle of the operation; Pizza Steve (Adam Devine), a smooth-talking slice of pepperoni pizza; and Uncle Grandpa's pet, Giant Realistic Flying Tiger, who often doubles as a mode of transportation for the crew.
