The fairy princesses have been invited to a ball in DREAM MOUNTAIN! It's the biggest event of the year, and they can't wait to wear the perfect outfits. But when they get to the mountain, things start disappearing. Accessories go missing, and tiaras vanish! Bluebell must use all of her detective skills to find their missing A-line multi-tiered ballgowns, and eventually a trail of sparkles (and some help from the dream fairies) leads them to a meeting with the Dream Queen herself.
