BeBe & CeCe Proud

 BeBe & CeCe Proud (voiced by Tara Strong) is Penny's troublemaking one-year-old twin siblings. BeBe is a boy with an afro and always has a bottle in his mouth, while CeCe is a girl with brown hair and a pink dress with pigtails. BeBe and CeCe are namesakes of 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.
