Beth Thomas

Bethany Yvonne "Beth" Thomas is a conceited and shallow cheerleader. She is also very arrogant. She is very jealous of Polly and is willing to sabatoge her and her friends in any way possible. In fact, she's so jealous of Polly that she can't see any reason why she and her friends can't get the opportunities Polly gets. For example, in "Polly Pocket: Lunar Eclipse", she is jealous that Polly's band is playing at the school dance and asks why she and her friends can't do it despite knowing that they have no band. Her two best friends are just as mean as she is, but she can also be mean to them and nag them to do things.

Appearance
Beth has long two-toned brown hair and green eyes. She typically wears anything green and short skirts.

Unlike the other characters in the series, Beth and her friends are the only ones not included in the doll franchise as they were only for the TV shows and movies.

Lunar Eclipse
For a science project, Beth learns that if Lila (Brittney Wilson) doesn't get a good grade, she'd be grounded and forbidden to play at the upcoming dance, which would prevent Polly's whole band from playing at the dance. Beth lets Lila borrow her camera and lies that she put a new roll of film in it when the film really has pictures from a family picnic. At first, Beth and her friends are pleased only for Polly and her friends to come up with a plan to fix it.

Cool at the Pocket Plaza
Beth and her friends overhear Polly and her friends talk about the Pocket Plaza and that they'll be performing live on TV, increasing Beth's jealousy because it'll make Polly even more popular. She tries again to humiliate Polly and her band in the show at the hotel. At first, she mistakes Polly's British cousin Pia for Polly herself until she learns that the cousins have been pretending to be each other. They pretend to be interested in Polly's band and have Miss Throckmorton overhear Pia's name. Miss Throckmorton, Pia's anti-American aunt, then kidnaps and locks up Polly (mistaking her for Pia) in her hotel room, forcing Pia go give out the speech instead. When Polly makes it back in time for her band, a defeated Beth craves vengance.
