‎Summer Impressions of the Planet‎ Z (1986)

Felix, a 12-year-old boy from outer space, during the summer holidays gets admitted into a summer children's sports camp. Few people know in the camp that Felix is not there by chance, and a few days ago he was created in a school laboratory because a space intellect sent him as an agent to planet earth to study humans. He is assisted by an ordinary boy Boris and a teacher who explains Felix local traditions and customs.
