BeBe & CeCe Proud are Penny's troublemaking one-year-old twin siblings. BeBe is a boy with an Afro hairstyle and has a bottle in his mouth, while CeCe is a girl with brown hair and a pink dress with diapers. They are named after the gospel music brother and sister duo, BeBe & CeCe Winans. CeCe is the older twin. They love Penny very much, but at points play too roughly with her. They are often seen playing with Puff, and most of the time, Puff ends up getting injured. Even though the film takes two years after the series, they remain infants and don't seem to have aged.
Al Roker once turned them into teenagers, which made them ruin Penny's life.
