Sesame Street

• Big Bird is a 8-foot-tall yellow bird. He was the first Muppet to appear on Sesame Street. His best friend is Snuffleupagus who looks like a mammoth with no tusks and was assumed to be imaginary by the rest of the cast, until the creators revealed him due to hearing about reports of sexual abuse cases of children. Performed by Caroll Spinney (1969–2018) and Matt Vogel (2009–present).
• Oscar the Grouch is dwelling green alien who lives in a garbage can with his pet worm Slimey and his pet elephant Fluffy. He is always in a bad mood and he loves everything that other people hate: mud, dirt, etc. He has a girlfriend named Grundgetta. Performed by Caroll Spinney (1969–2018) and Matt Vogel (2009–present).
• Bert and Ernie are two roommates. Ernie is more active and always ready to play a game or make a mess. Bert is an often boring grouch who likes to read; he likes things to be clean, neat and loves pigeons. They are rumors that they are gay, which Sesame Workshop has denied.
• Cookie Monster is blue, has a baritone voice, and eats large amounts of cookies. It was rumored that he would be renamed the Veggie Monster in an effort to promote healthy eating, but that turned out to be untrue. He also once had his own skit where he introduced parodies of famous books, movies, plays, and TV shows.[14] Performed by Frank Oz (1969–2004) and David Rudman (2001–present).

• Kermit the Frog is one of the first Muppets designed and built by Jim Henson.[15] Borgenicht calls Kermit "funny, ironic, and always the voice of reason amidst the insanity around him; the calm in the eye of the storm".[16] He was a star on Sesame Street until 2001. He had his own skit where he interviewed characters from fairy tales, nursery rhymes, and history.
