Zoe is a three-year-old monster who first appeared on Sesame Street in Season 25.

Zoe was created to help balance what was then a predominately male cast of Muppets on the series. The color orange was chosen for her design to complement Elmo, who was gaining popularity at the time of her introduction.

Apart from some light jewelry, Zoe was originally unclothed. Beginning in season 33, she started wearing a tutu, as — like many girls of her age — she is obsessed with ballet. Her love of dance is featured in several episodes, as well as the home video release Zoe's Dance Moves.

She occasionally rides a soapbox-style car around Sesame Street, called the Zoemobile, and can sometimes be seen with one of two recurring transitional objects: a pet rock named Rocco and a doll named Mimi. She attended the Day Care Center from season 25 to season 29, and generally celebrates her birthday on September 30 (although this date has been inconsistent).

Her Aunt Chloe has been seen on the show, and her father has appeared in a few storybooks. Her Aunt Giselle, who lives in Swan Lake, sent her a tutu in season 34.
