Shelly Klutzberry (voiced by Candi Milo) is Shelton's older sister who has fewer appearances than her brother. She resembles her brother, but doesn't change appearance when her glasses are taken off. In "Late Night with Todd & Riley", she is first mentioned as Shelton's sister and also we learn she loves Dustin Dreamlake. Though never mentioned, she has presumably already had her bar mitzvah.
