The LEGO Disney Storybook Adventure sets are a subset within the LEGO Disney theme, designed to resemble books that open up to reveal a miniature playset inside. Each set represents a different Disney story, such as "Frozen," "Mulan," "Beauty and the Beast," and "Ariel's Undersea Adventure." Inside the book-like case, there are small dioramas or scenes relevant to the respective movie, along with micro-dolls and other accessories
