From Muppet Wiki

Roxie Marie is Biff's niece, an intelligent young girl. She appeared on Sesame Street from Season 23 through Season 27.

In her early appearances, she spoke in a high, whispery voice, similar to how the early Prairie Dawn sounded. When she became Biff's niece, she soon developed a thick New York accent.

She appears talking to a kid, in the background of Sesame Street Stays Up Late.

A similarly designed puppet is used as Griotte on 5, Rue Sésame.
