The third title in the brand-new Sticker Dolly stories, a fiction series inspired by Sticker Dolly Dressing. It’s the night of the Undersea Gala on the Enchanted Isle, and Nerissa the mermaid can’t find the grand prize – the Shining Pearls. Have they been stolen? Who would do such a thing? The Magic Dollies are given magical skirts that transform into mermaid tales, so they can swim and breathe underwater – can they recover the Shining Pearls before it’s too late?
