The animated film is based on the story of the same name by Lia Geraskina.
In the adventures of Perestukin, there are no moments of meeting with the winged kangaroo, the old woman Drought,
There are also no scenes of the war of Ivan the Terrible with Napoleon Bonaparte, the amended decision of Vitya about the task of the tailor, about the brother and sister, about the rider.
All obstacles of Vitya and Kuzya in the cartoon are in reverse order.
In the cartoon were added details that are not in the book: watermelon tree, talking radio, playing football in a tin can.
