Going Underground

S1, E5: Sections of Acmetropolis are literally being turned upside down when a crazed geologist who lives beneath the planet's crust is determined to turn the world, "inside out", to create a new home for himself and his boulder beasts. It's up to the Loonatics to stop him by burrowing deep below the surface in one of Tech's cool drilling vehicles to confront the geologist, destroy his crystal operated machine and return Acmetropolis to normal.
