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. He will appear in MYCUN Forever in his DanLuVisiArt style, called "The Cook".
