Elmo is a red muppet monster from Sesame Street. He is best known for speaking mostly in 2nd and 3rd person talk, and he loves his pet goldfish, Dorothy, and to be tickled. He also loves his family, friends and teaching others about certain things. Elmo has his own segment called Elmo's World, and is also a supporting character from 1979 to 1989 and the main protagonist from 1990 to present and the film "Elmo in Grouchland". He was always performed by Kevin Clash, who used falsetto while voicing him. And in 2012, he is now currently performed by Ryan Dillon.
Elmo lives in an apartment on Sesame Street with his mother Mae, his father Louie, and, in some storybooks, a sister named Daisy. He has a pet goldfish named Dorothy.
Other relatives in Elmo's family include his grandma and grandpa; his great- grandmother (featured in a 1989 episode) and his great-grandfather (named Selmo); his Uncle Jack, Aunt Jill and cousin Jesse (featured in When Families Grieve); plus additional cousins Elmer (featured in Kids' Favorite Country Songs) and Chester (featured in Here For You). Additionally, the television special Sesame Street Stays Up Late shows Elmo's "international" cousins — Pepe from Mexico and Elmonosuke from Japan. As seen in The Furchester Hotel, he also has an aunt Funella Furchester, an uncle Furgus Fuzz, and a cousin Phoebe Furchester-Fuzz.
Elmo's early childhood has been shown with Elmo as a 13-month-old infant in the Sesame Beginnings video series, and in flashbacks shown in Elmo's Potty Time and "Bye Bye Binky.
As with many children of his age, Elmo is seen somewhat infrequently with a favorite toy of his: an orange monster-like doll named Baby David. In the film The Adventures of Elmo in Grouchland, Elmo is devoted to his blue blanket, Blanket.
Elmo's birthday is February 3rd.
Sesame Workshop describes the character as: Elmo is a 3½-year-old red monster with a high pitched voice and a contagious giggle. Enthusiastic, friendly and cheerful, he always wants to be part of everything that goes on. However, like most preschoolers, he sometimes doesn't have the skills or knowledge to do what he wants. But that never stops him because he has a very positive, optimistic view of himself and life. Elmo's best friends are Zoe and Abby, and also his pet goldfish Dorothy. Elmo loves eating his favorite food, wasabi. He also loves riding on his tricycle and being tickled.
