Bob and Lofty are going to construct the museum's new pyramid exhibition building. Lofty is excited that he gets to use his new claw attachment. Upon arriving at the site, they discover that Tiny has already built most of the pyramid for an archaeologist, Anish Bose, who wants to put his exhibits inside the central chamber. Lofty wants to finish up the work by himself but places a stone at the entrance of the pyramid by mistake, trapping Bob, Wendy, and Anish inside! Lofty realizes that his eagerness to do too much on his own caused the problem, and that working as a team with Tiny is much better.
