Larry and Amelia consult the Einstein bobbleheads for help on finding the secret at the heart of the Pharoah's tomb.

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.
