About the book: 2016 / They are cute, they are fluffy... but they cause only problems! Strange events began to happen in Arendelle. Someone ate all the pies from the bakery, the fish from the pier, and scattered laundry in the city laundry. This had never happened in the kingdom before. Anna and Elsa decide to find out what's wrong at all costs. It turns out that this is the work of polar bears. But they had never wandered this far south before. Sisters must help bring animals back to the Arctic!
