The inhabitants of the Moon defeated the Earth, but then left for an unknown reason. The sunny city has been reduced to ruins. After many years, the residents of the Flower City partially restored their former, happy world. But they had to grow up to cope with new challenges. Now everyone knows how dangerous space is. All except one. Author's notes: What if Nosov's original fairy tales about Dunno are a reflection of real historical events in one parallel world? Let the short people there be of normal human height, just as there are no giant plants, no wizards, but everything else is the pure truth. Then this world is very similar to ours.
