Elmo is a red Muppet character on the children's television show Sesame Street. A furry red monster who speaks in a high-pitched falsetto voice and frequently refers to himself in the third person, he hosts the last full five-minute segment (fifteen minutes prior to 2017) on Sesame Street, "Elmo's World", which is aimed at toddlers. He was originally performed by Kevin Clash. Following Clash's resignation in late 2012, Elmo has been performed by Ryan Dillon.
