Cookie Monster is a Muppet on the children's television show Sesame Street. He is best known for his voracious appetite and his famous eating phrases: "Me want cookie!", "Me eat cookie!", and "Om nom nom nom" (said through a mouth full of food). He often eats anything and everything, including danishes, donuts, lettuce, apples, bananas, as well as normally inedible objects. However, as his name suggests, his preferred food is cookies. Chocolate chip cookies are his favorite kind; oatmeal cookies are his second favorite. In a song in 2004, Cookie Monster revealed that, before he ate his first cookie, he believes his name was Sid.^[1] Showing awareness of healthy eating habits for children, since 2006 he has said that cookies are "a sometime snack" and that he also likes fruits and eggplant.
He is known to have a mother, a younger sister, and an identically-designed cousin, who all share his characteristic blue fur and "googly eyes". He also has a father, who appeared in a Monsterpiece Theater sketch promoting energy conservation, water conservation and environmentalism. Both Cookie Monster's mother and father have his enormous appetite. He and his Sesame Street friends are popular motifs on T-shirts. (sumber : wikipedia)
