The Drill Engine Train burrows into an underground limestone cave, where the Pteranodon Family meets some strange creatures without eyes called "troglobites." In a contest to see who would make the best troglobite, Buddy, Tiny, Shiny, and Don participate in a treasure hunt - with their eyes closed. The kids have to rely on their other senses (with some guidance from the actual troglobites) to navigate the cave and find the prize. "What's At the Center of the Earth? Minerals!" While digging even further underground, the drill bit on the Drill Engine Train breaks. The Pterandon Family find themselves in the Cave of Giant Crystals, where they learn all about rocks and crystals (what they are, how they're different, how they form). In order to get back home, the Pteranodon Family has to fix the drill bit by finding a mineral harder than the mineral that broke the bit in the first place. See less
