The cartoon consists of several mini-cartoons: "Liar" based on a poem by D. Kharms, about a boy who fantasized a lot and passed everything off as the truth, but no one believed him. "The Key" is based on a poem by O. Grigoriev, about an old grandmother who left a key at home, but her granddaughter did not open the door for her. "The Ball" is about a boy who dreamed of becoming a football player and therefore could not part with the ball.
Sorry, but for now we weren't able to find movies like Recess IV.
