The Stepsisters
From Muppet Wiki
Cinderella's Stepsisters are extremely stuck up and have such obnoxious voices that it's often hard to decipher what they're actually saying. Featherstone describes them as "crummy" after they arrive at the King's birthday party.
Their stepmother referred to them as "Lisa" and "Mona", though neither sister is individually referred to as such.
Trivia
- One of the sisters appears in a 1969 Sesame Street segment, a cover of the song "Gone with the Wind," where her hair is blown away.
