Big Police Tale (1990)

One day the police were checking city blocks and found a dragon egg, which was immediately taken to the lost and found table. And there a five-headed dragon hatched from the egg and ate everything that was in the lost and found table for storage. Not knowing what to do with the charming monster, the police are trying to place him either in an orphanage or in an animal protection society. But everything is in vain, because in fact the dragon is an enchanted princess.
