Polly says 'Who needs perfect when you've got friends
Polly has blonde hair styled in a ponytail, light skin tone, and light blue eyes. Though with any set purchased with her, her hair style can change from being in a ponytail to pigtails or cut short. Like the other dolls, her hair can either be plastic or made from nylon. She tends to wear a lot of bright clothing such as pink, yellow or purple.
Polly seems to have a very close relationship with her friends, especially those in her core group. They are:
Polly's family is wealthy, in regards to her father, John Pocket. At a young age, she lost her mother, leaving Polly with her father. As a result, Polly loved him deeply although she wasn't able to receive the attention she desired as John was always busy. Polly maintains a close bond with her butler, Samuel, and considers him a father figure who she can talk to when her father is not around.
Her father's ex-fiance, Lorelei, in the movie "PollyWorld" was going to be Polly's stepmother. But she didn't want to raise Polly and wanted John to herself as she is extremely jealous of Polly for having her father's affections, so she plotted to get rid of Polly by tricking John into thinking his daughter needs structure as her life is stressful, which was actually a lie. John agreed and he called a boarding school to take Polly after the contest was over. However, during Polly's performance, Beth, who Lorelei was in an alliance with to sabotage Polly's team and getting rid of her, brings Lorelei to the sound booth as she threatens Lorelei to make sure her team wins the competition or she'll tell John about Lorelei's true intentions of sending Polly away as Lorelei was not keeping her end of the bargain to help Beth achieve fame as she promised. Unbeknownst to them both was that they were live from the sound booth and everyone heard Lorelei's confession, including Polly and John, causing John to confront her for what she really thought of his daughter and staff and calls off their engagement, leaving Lorelei devastated that her plans have failed.
Polly also has a cousin named Pia and an aunt from England. Pia and Polly look very much alike and the two became close.
