Cookie Monster is a popular Muppet character on the children's television show Sesame Street. He is covered with blue fur and has "googly eyes", but he is most known for his voracious appetite. He can (and often does) eat anything and everything, but his favourite choice of food above everything else is cookies, hence his name. (Chocolate-chip cookies are his favorite kind.) The character has been performed by Frank Oz and David Rudman.
