The Magic Bells(1987)

Original title: Волшебные колокольчики

A good tale about the inhabitants of a magical city who were shamelessly robbed by the villain Miraclus. He stole their smiles - sly, playful, tender, affectionate - and melted them into golden bells! The Miracle dungeon was filled with a quiet, clear ringing sound, fresh and transparent, like a forest spring. He enjoyed this music, but the people in the city looked at each other with sad eyes and thought that joy had left them forever. But one day a cheerful company came to this city - a kind wizard, a girl Katya, a boy Vasya and a cartoon cat that came to life - and helped the residents return their smiles.
