Elmo is a Muppet on the children's television show Sesame Street. He is a furry red monster with large white eyes and an orange nose. He currently hosts the last full 15 minute segment on Sesame Street, Elmo's World, which is aimed at toddlers. He is accompanied by his goldfish Dorothy and silent Charlie Chaplin–like characters named Mr. Noodle, Mr. Noodle's Brother Mr. Noodle, and sometimes, Mr. Noodle's sister Miss Noodle (played by Kristin Chenoweth). His puppeteer is Kevin Clash, who uses falsetto to produce his voice. Elmo's parents, Mae and Louis, speak with Southern American accents.
