Cookie Monster is a Muppet on the long-running children’s television show Sesame Street. He is best known for his voracious appetite and his famous eating phrases, such as “Me want cookie!”, “Me eat cookie!” (or simply “COOKIE!”), and “Om nom nom nom” (said through a mouth full of food). He eats almost anything, including normally inedible objects. However, as his name suggests, his preferred food is cookies. Chocolate chip cookies are his favorite kind. In a song in 2004, Cookie Monster revealed that, before he ate his first cookie, he believed his name was Sid or Sidney. Despite his voracious appetite for cookies, Cookie Monster shows awareness of healthy eating habits for young children and also enjoys fruits and eggplant.
He is known to have a mother, a younger sister, and an identically-designed cousin (who ironically does not like cookies), who all share his characteristic navy 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 share his enormous appetite and craving for cookies. He and his Sesame Street friends are popular motifs on T-shirts.
