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 host of Dancing with Triangles, Tom Twinkletoes, invites contestants on stage to perform their best dance with a triangle. The contestants dance with hexagons, squares, and even an elephant, but only one dances with a triangle. Tom explains why the other geometric shapes are not triangles.
