Three gymnasts become secret agents.

Barbie and her sisters discover everything's better when you do it together in this splashy, sun-kissed adventure. After the girls and their pets arrive at an island paradise for Chelsea's big dance competition, they decide to make a quick side trip to see the nearby Dancing Horse Festival. But when their furry friends go missing at the event, it's up to the sisters to find them before Chelsea's show.
