Pac-Man and his friends starts taking their driving tests with Pac-Man's driving teacher Mr. Strictler, a strict PacWorlder, until Pacopolis starts getting tremors like crazy as Dr. Buttocks creates a drill to burrow above the ceiling of the Netherworld. When Pac mourns over not getting license, the others try to make him feel better. In the secret lab, another earthquake occurs.

The former and the latter discover that if the drill reaches the surface of PacWorld, the whole city would sink into the Netherworld.
