 Peebri, Peegi, Peebrit, are each modeled after Brianna, Gina, and Brittany respectively, so by raising them, Brianna can picture what it would have been like if she grew up with her sisters.As such they have a relatively free rein and are encouraged to learn for themselves, but unfortunately Peebri's antics are often destructive and/or silly, although highly amusing.The Peebos have starred in their own spin-of miniseries, where the less advanced series models occasionally guest star.
