Чудесная песня мышки Поли

Many years ago, in an old boot, thrown away by someone on the riverbank, a glorious mouse family settled. For a long time, there was silence and calm in the house, until Poly was born - a little mouse with... an amazingly beautiful and strong voice. The little one loved to sing so much that she could sing for days on end. At first, the family couldn't get enough of her talent, but soon delight turned into disappointment: she couldn't do anything else! Since then, Poly only helped her relatives with household chores. And she completely stopped singing... But one day, an uncle who had left the boot long ago in search of sea adventures docked by the shore. His dream has not yet come true, but he is ready to help his passionate niece become a great singer...
