The game begins with Pac-Man and his friends walk into Sir Cumference's lab. Three golden orbs are on a table, and while Sir C is explaining what they are to Pac-Man, four ghosts from the netherworld (Blinky, Inky, Pinky and Clyde) come and tell Pac-Man that Pacopolis is under attack by the forces of Betrayus, king of the netherworld. They do so to steal the Frigidigitator, a device Sir C made for when Betrayus would make another heat-wave device like the one from Season 1's "Betrayus Turns the Heat Up".
