Sinopsis

The fly, flying over the field, found a coin. Pleased with this fact, she went to the bazaar to buy a samovar and invite her friends to celebrate her birthday. But then a misfortune came - a spider burst into the festival and stole our fly. None of the guests decided to join the spider in a duel, except for a small, but brave gnat. Fortunately, everything worked out, and fly and gnat made a harmonious pair.
