The CyberSquad needs to get across a pool of lava. They find tiles in the shapes of triangles, pentagons, and hexagons, and tessellate the tiles in order to create a bridge that will shield them from the heat. When they run out of triangles in the middle of creating the bridge, they attempt to use pentagons, but that shape leaves gaps, so they use hexagons to complete the bridge.
The narrator shows Donald Duck several occurrences of mathematical forms in nature, such as the petuna, the starfish, and the wax flower. He explains that math can be found in music, art, and virtually all other aspects of the world.
