This is a nice funny story about two plasticine men, busy with a very important matter - Tyap and Lyap paint the factory fence. Cartoon characters literally fall from the sky to the ground. And along with them - and buckets of paint, blue and yellow. Tyap and Lyap enthusiastically start to work, but there is one mistake - they did not agree among themselves, what color they will paint, so the fence is spotted. Then, angry at each other, Tyap and Lyap begin to break the boards, fortunately, quickly find a compromise: it turns out that if you mix yellow with blue, you get green - this will be the new color of the fence.
