Grandpa Wetworth is Junior's and Willie's grandfather as well as Governor Wetworth's and Long John Wetworth's dad. He has gray hair and wears glasses and a long green turtleneck. He only appears in three episodes of Season 4 - In Greed We Trust, The Story Circle, and I'll Be Senior. He is very friendly and knowledgable to the other snorks, and they in turn look up to him. He gives advice and tells stories through the game of "story circle." He is very active for his age, despite having been ridiculed about it one time. During this time, however, he was sent to a retirement home, where he met other elderly snorks such as Rosie and Al. The three saved the town after Bigweed and Lil Seaweed turned them into babies. Grandpa is voiced by Frank Welker.
