Much like her son, Benny, Mrs. Ball is a rather short and chubby blue cat with peach-colored facial markings and muzzle. Her eyes are also small little dots, and she has exactly four whiskers. She is a bit curvier than her son, however. She wears a cute little white sunhat with a yellow flower in it - presumably a black-eyed susan - and a pair of glasses perched across her muzzle. Her dress is a simplistic, but quite puffy, sky blue with frills. Mrs. Ball also wears an elegant pair of blue Victorian-era styled boots.
Mrs. Ball lives in Bacon Fat Flats.
Penny is known as "Nanny" in the middle east.
