Sesame Street's lovable, furry red monster, Elmo, invites young viewers to explore three subjects of enormous interest to kids. First up: What makes a family? Elmo looks at all sorts of families and talks about the joy of being part of one. He also explores how mail journeys from the sender to the recipient, and then ends the episode with a discussion on how to keep clean while he takes a dip in a soothing bath.
