Polkan served faithfully and true to his masters for many years. Once he was a quick puppy, and then he became a strong and brave dog. And now what? Eh, old age is not fun. There's a young kitten, a duckling and a chick playing, frolic in the courtyard, they call him to play. And which of him is a player - old bones, the whole body hurts. If it was possible to regain youth. And it's possible, you just need to go to the forest at night and to break the magic flower.
