Herry Monster Herry Monster is a " Sesame Street " monster who doesn ' t know his own strength . Herry first appeared in season 2 , effectively replacing the Beautiful Day Monster in the " Sesame " monster troupe . In his first appearances , Herry ' s nose was covered with light blue fur as well . During the second season , he gained a non - furry blue nose , which was replaced by his signature purple nose in 1971 . The Herry puppet was also used for the original Big Bad Wolf . Although Herry has been performed by Jerry Nelson from the beginning , Jim Henson performed his voice in the song " Up and Down " with Cookie Monster ( using a recycled soundtrack from " The Sesame Street Book & Record " , where the song was credited to " Two Monsters " ) . Herry was often seen in Muppet & Kid Moments , relating to real children , and in later seasons appeared in the recurring sketch Monsters in Day Care . Herry has also participated in many of Prairie Dawn ' s pageants , as well as appearing in such " Monsterpiece Theater " segments as " Chariots of Fur " , " Guys and Dolls " , and " ABCD Blue " . Herry hosted the Fuzzy Awards in the video " Monster Hits ! " and he was an anchorman in " We All Sing Together " . He has a mother , a father and a grandmother . He has a sister named Herriet ( seen in a 1977 episode ) and another named Flossie , seen in several storybooks . He also has a doll named Hercules who has been seen with him in " Guys and Dolls , " " A Song for Two , " " Moonshine " a song with Zoe where they sing about their dollies , and when he slept over at Gabi ' s in a 1998 episode . Herry is known for appearing in illustrations ( and some merchandise and on the " Sesame Street Live " productions ) with pants on . Usually they would be white with pink stripes , but the costume used in " Sesame Street Live " would give Herry light blue pants , and illustrator Tom Cooke usually drew Herry in purple pants with orange spots . He hasn ' t been seen wearing pants elsewhere , and the few times he has been shown below the waist , he has been nude , like most monsters . Another attribute of the character from illustrated merchandise is that Herry was sometimes depicted as the proprietor of a barber shop on Sesame Street . Usually wearing a short - sleeved barber ' s shirt and his customary ( for illustrations ) striped pants , Herry could be seen working at Herry ' s Barber Shop in the 1983 book " People in Your Neighborhood " , a puzzle from Sony , the 1986 Rub n ' Play transfer set , and the Busy Builders Playtown . Like Cookie Monster , in rare instances Herry has taken to eating traditionally inedible objects , such as a bicycle , a restaurant table , the letter in M - M - M Monster Meal , but usually in the company of his googly - eyed friend . Though Herry still makes occasional appearances in new episodes , he seldom plays a prominent role . He can be seen in " The Street We Live On " and made a cameo in Episode 4206 ( puppeteered by Marty Robinson ) , in line at Hooper ' s Store . In 2013 , Herry made his first speaking appearance in a decade at the " From Broadway With Love " benefit concert , where he was performed by Tyler Bunch . Since 2015 , Peter Linz has been cast in the role . Linz ' s first public performance as Herry was for a 2017 # ShareTheLaughter video . His first performance of Herry on the show was in Episode 4816 . Herry ' s birthday is August 31st . See also . _ _ NOWYSIWYG _ _
