Open the book and explore a whole micro-world in a castle! Cross the bridge into Arendelle Castle and check out all the cool things inside. Play a tune with Disney Princess Anna while Disney’s Elsa sings along, then head to the bedroom for a quick nap. Once you're refreshed, bundle up and hop onto the sled, Elsa's making it snow outside! Wheee! It's so much fun to go sledding with friends! Want to build a snowman?
