It's Miley's birthday, and she's having a sparkle-themed party! It will be held at an indoor ice-skating rink, and she got custom sparkle skates from her grandma as an early birthday gift. She and her friends will skate all day! JoJo has spent weeks making the perfect glittery decorations for the rink. But when Miley breaks her ankle the week before her party, her mom has to cancel the big bash. Never fear-JoJo, Jacob, Kyra, and Grace to the rescue! The friends plot the perfect plan for bringing the fun to Miley: a sparkly slumber party! Blanket forts + tons of popcorn + movie marathon + giggles all night = Miley's best birthday ever.
