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 the ancient Tree Of Life, young pac has the ability to eat ghosts... And burp out their eyeballs! Wow! Unfortunately, the ghosts mange to steal the Tree Of Life, which could mean the end of Pac-World!
Lord Betrayus plans to render Pac powerless - by getting Inky, Blinky, Pinky and Clyde to feed Pac so much he'll be too full to eat anything else... power berries or ghosts! But Pac isn't getting full, even when he's eating everything in both worlds!
When Pac and his pals get blasted into the past, he not only finally meets his parents -- and his Baby Pac self - but has an adventure with them during PacWorld War I.
Pac-Man is physically controlled by Betrayus when he swallows a special micro-chip, and Pac's friends must help him infiltrate the Netherworld spy-style to retrieve the remote controller.
PacWorld is becoming dangerously hot and its citizens mistakenly blame Sir C! Pac and Friends remain loyal to the elderly inventor and, together; they uncover a plot by Betrayus to terra-form PacWorld into a world just like the Netherworld prior to invasion and conquest.
It looks like Betrayus" fortunes are changing when he summons a Nether-Witch to curse Pac Man with bad luck. The only catch is, the witch will only turn over the potion if Betrayus promises to marry her.
There's a new threat to PacWorld, a debonair spy ghost named Specter. He possesses Aunt Spheria's dog Uggles, infiltrates Sir Cumference's lab, and proves to be a worthy adversary to Pac. To stop him, Pac gets help from an unexpected source.
Apex, the Pointy-head alien, strikes a deal with the Netherworld to join forces and take over PacWorld, but Betrayus has no idea that the aliens are even more duplicitous than he is. There is only one chance for victory, Betrayus must give Pac-Man control over the entire ghost army... including Betrayus!
