The title of this dismal, Russian-produced animation is a mashup of the Tchaikovsky ballet and the Mozart opera. However the story, a nonsensical magical Christmas quest involving evil humanoid rats, has little bearing on both. Teenager Marie is threatened with marriage in an effort to save her mom from debtor’s jail. For some motive she shrinks, and all her favorite childhood toys, together with the world’s most punchable ostrich, come to life. The animation type is artificial, the story is illogical, and the songs make you need to plug your ears with stollen.
