Loretta

From Muppet Wiki

Loretta is one of Kingston's friends on Sesame Street.

Often seen with her crew of friends, Loretta is usually the first one to observe Kingston's unique, original qualities that are different from the other kids. When Kingston explains how he enjoys being different, she shrugs it off and finds the originality cool as well.

Loretta never became a regular character, and was originally played by Camille Bonora, then Alice Dinnean-Vernon. In one segment, her only solo appearance, she sang a song about emotions in the park with her dog. She was played by Louise Gold for the song.
