Kane appeared on Sesame Street in a 1989 episode as "Nina the Nice", the only nice person in Grouchytown. In the episode, Bob accompanies Oscar the Grouch on a trip to the hometown of Grouches. Just as Sesame Street has lots of nice people and one Grouch, Grouchytown has lots of Grouches and one nice person. Kane is exceptionally nice, and drives all of her grouchy neighbors up the wall.
Archive footage of her Sesame appearance was included in the 1994 special Sesame Street All-Star 25th Birthday: Stars and Street Forever!
