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 Legend of Last Yellow Orb proves to be true: thanks to power-berries from the ancient Tree Of Life, young Pac has the ability to eat the ghosts… and burp out their eyeballs! WOW! Unfortunately, the ghosts manage to steal the Tree Of Life, which could mean the end of PacWorld!
