Mr. Noodle appears in the "Elmo's World" segment of Sesame Street. A silent character, Mr. Noodle resides in a realm of his own inside Elmo's World, accessible from behind Shade. Elmo frequently asks Mr. Noodle to demonstrate how to perform a chore or answer a question. He responds through pantomime, but invariably gets the process wrong, or fails to follow Elmo's instructions. Through trial and error and repeated prompting, Mr. Noodle usually manages to figure it out.
Introduced along with Elmo's World in Season 30, Mr. Noodle was replaced by Mr. Noodle's brother, Mr. Noodle for Season 31. Subsequently, the two Noodles either alternated or occasionally appeared jointly, as in the episodes "Families" and "Games."
