The evil, ghostly ruler of the underworld, Lord Betrayus, is at it again. Only this time he's not targeting Pac-Man's world like always. Thanks to a long lost friend of his, Betrayus has found a more vulnerable location for his ghost army; Equestria. Now, thanks to the 4 friendly ghosts; Pinky, Inky, Blinky, and Clyde, Pac-Man is hungry as ever and ready for action. But after following Betrayus into the portal his henchmen have created, our yellow hero soon learns that it'll take more than his arsenal of power pellets to stop the underworld ruler's evil schemes.
