She is an anthropomorphic female rabbit who moved from New Orleans, Louisiana to Elwood City in the season sixteen premiere episode "Based On a True Story". She attended Lakewood Elementary as a third grader in Mr. Ratburn's class and soon became part of Arthur's gang. Her main hobby is to tell many interesting stories about her family. In the season twenty-three finale episode "When Duty Calls", she and her family relocated to Oregon.
