The character was created by writer Nancy Sans, originally as a day player role. Her first episode, in season 18, involved her getting lost on the way to 123 Sesame Street, where Gordon and two directionally-abled science class students were watching the night sky.
When she was introduced as a regular, she worked at Hooper's Store, getting the job in Episode 2358. She has developed friendships with Mike and Savion, and had a romantic relationship with Jesse. She graduated from high school (Class of 1990) at the end of season 21 in Episode 2745 and continued to work at Hooper's Store while figuring out what life path to follow.
In Episode 3397 (Season 27), she revealed that she wished to work in child care and had taken night classes, earning her teaching certificate and working part-time at a day care center. From season 27 to season 29, she ran the day care center located Around the Corner.
