Cookie Monster is a blue Muppet character on the PBS/HBO children's television show Sesame Street. He is best known for his voracious appetite and his famous eating catchphrases, such as "Me want cookie!" As his name suggests, his preferred food is cookies; though he eats almost anything, including inedible objects. Chocolate chip cookies are his favorite kind. His speech is often grammatically nonstandard; for example, he always uses "Me" to refer to himself in place of "I", "My", and "Mine". Despite his voracious appetite for cookies, Cookie Monster shows awareness of healthy eating habits for young children and also enjoys fruits and vegetables.

Googly eyes, or wiggle eyes, are small plastic crafting items used to imitate eyeballs. Googly eyes traditionally are composed of a white plastic or card backing covered by a clear, hard-plastic shell, encapsulating a black plastic disc. The combination of a black circle over a white disk mimics the appearance of the sclera and pupil of the eye to humorous effect. The inner black disk is allowed to move freely within the larger clear plastic shell, which makes the eyes appear to move when the googly eyes are tilted or shaken.
