<P> The Three Bears from the story of Goldilocks appear in Muppet form on Sesame Street . Also appearing on the show are an unidentified species of furry characters referred to as "monsters". Among these are Cookie Monster, a blue monster who is addicted to the baked goods for which he is named but ironically also likes healthy foods; Telly Monster, a purple worrywart who overthinks everything, was described by writer David Borgenicht as "neurotic", and was originally portrayed as a television addict; Zoe, a yellow - orange female monster who is "simultaneously dainty and strong, practical and impulsive" and loves to dance ballet; and Rosita, a bilingual turquoise monster (also female) who speaks both English and Spanish . Grover, a blue monster described by Borgenicht as "self - confident, furry, cute, capable, and intelligent", has a superhero alter - ego named "Super Grover", who is more well - meaning than helpful . In addition to Ernie and Bert, recognizable humanoid Muppets appearing on the show also include Count von Count, a number - obsessed vampire based on Bela Lugosi's interpretation of Count Dracula; and Prairie Dawn, a methodic and driven young girl who loves to write and direct pageants featuring her friends . </P> <P> One Muppet monster who became a household name in the show's recent history is Elmo, a red monster representing the three - to four - year - old child . Elmo became what his eventual portrayer, Kevin Clash, considered a "phenomenon" after Clash took over the role in 1983, and his popularity ultimately grew to the point where he became what writer Michael Davis called "the embodiment" of Sesame Street . In 1998, the Muppet got his own segment occupying the last 15 minutes of the show, "Elmo's World", in which he explored child - centered topics from two worlds of live action and computer animation, which looked like "a child's squiggly crayon drawing come to life". "Elmo's World" continued until 2012, when another segment starring the character, "Elmo the Musical", was introduced to replace it . </P> <P> At the show's twenty - fifth anniversary in 1993, the producers expanded and redesigned the show's set with a new series of locations dubbed "Around the Corner", which was dropped from the show in 1997 . One of the "Around the Corner" locations, the Furry Arms Hotel, had a few original Muppets of its own: proprietor Sherry Netherland, managers Humphrey and Ingrid (who had a baby named Natasha), and bellhop Benny Rabbit . While the rights to Muppet characters from other productions were sold to The Walt Disney Company in 2004, Sesame Workshop continued to fully own the Sesame Street Muppets; as a result, Sesame Workshop was and is allowed to have new Muppets designed and built for the show . These have included Abby Cadabby, a pink fairy - in - training, who was introduced in 2006 to increase the number of the show's female Muppets; Murray Monster, an orange monster with an energetic, outgoing personality and a sense of quick wit, who hosts a segment at the beginning of each episode called "Word on the Street"; and Julia, the first autistic Muppet on the show, introduced in 2017, who was created to familiarize young children with the autism spectrum . </P> <P> Other Muppets that have appeared on Sesame Street over the years have included the Two - Headed Monster, who teaches cooperation while speaking in baby - like gibberish; the Twiddlebugs, a family of cute and innovative insects; the Yip Yips, a species of Martians who "valiantly explore our world despite their frequent terrifying encounters with everyday objects"; game show host Guy Smiley; construction workers Biff and Sully; Herry Monster, a burly blue monster who does not know his own strength; Forgetful Jones, a "simpleton cowboy" with a short - term memory disorder; and even Kermit the Frog, the flagship character of The Muppets . </P>
