Uncle Grandpa

Uncle Grandpa has a large lumpy-staircase-shaped head, a red horseshoe moustache, pink nose, a red fanny pack that talks, a propeller hat, and an outfit consisting of a white shirt, lederhosen with rainbow suspenders, knee high tube socks, and black shoes. His outward appearance is very childlike and simplistic, and he is well-meaning, fun-loving, supporting, somewhat wise and surprisingly competent. In "Uncle Grandpa Sitter" he reveals that one of his abilities is to create a duplicate of himself, which he does in many episodes. His catchphrase is "Good morning!"
