In the video, a cartoon pig is standing in front of a chalkboard with the word "SHAPES" written on it. The pig is holding a stick and is drawing a triangle on the board. A cartoon duck is standing next to the pig, watching the drawing process. The pig finishes drawing the triangle and turns to the duck, who is now holding a green triangle. The pig points at the triangle on the board and then at the duck's triangle, and the duck begins to dance with the triangle.
