In the apartment of a student-botanist, Yura, plants lead an active life: they intrigue and observe the outside world. A green mafia stays vigilant, weaves conspiracies, and argues. Although Kirill the cactus seems to have given up his plans to seize humanity, the situation changes with the appearance of Valera’s new mysterious “green” friend. The plants are alarmed: is he an ally or a spy? What can a “green” person do—eat them or enslave them? Kirill the cactus realizes it’s too early to calm down and decides to fight back. Irina Lake is a writer and translator awarded prizes for children’s literature. The illustrations for the story were created by Olga Surina, and the audio recording was produced by the VIMBO Audio Publishing House with the participation of producers Vadim Bukh and Mikhail Litvakov.
