Thanks to the school bully, Pac-Man accidentally opens the portal to the Netherworld, unleashing an army of ghosts, led by the fiery Lord Betrayus! Lucky for Pac-World, the power-berries from the ancient Tree Of Life gives young Pac the ability to eat the ghosts... and burp out their eyeballs!

PacWorld is under siege by ghosts and there is little Pac-Man can do about it without fresh berries from the Tree Of Life, which is hidden somewhere in the Netherworld and guarded not only by legions of ghosts, but fierce monsters as well!
