Moscow Zoo
Captain Zelyonyy, Professor Seleznyov and his daughter Alisa Selezneva set out from Earth aboard the Pegas (Pegasus) starship, seeking out new animal species for the Moscow Zoo. Visiting the Moon as a resting point, Seleznyov meets his friend, Gromozeka the alien archaeologist, who advises him to turn to the Planet of Two Captains, a huge museum dedicated to Captains Kim and Buran who went around the whole universe on their ship, the Blue Seagull, for useful information on where the rare animals live. Doctor Verkhovtsev, the director of the museum, is seen visiting the moon as well; however, he avoids Gromozeka.
