Mezmeron learns of a power pellet forest in the Pac-Alps and goes with the Ghost Monsters in hopes of finding it. Pac-Man and Pepper pursue in hope of finding it first and keeping it away from the villains. It's a dangerous journey as it's known that an abominable Snow Pac-Man creature exists in this same forest.

After their car runs out of gas, the Pac-Family winds up in an old western ghost town. Sure enough, the Ghost Monsters aren't far behind with their young cousin Dinky in hope of recreating an old "Chomp Out"--only with them as the victors to prove he can have the potential to be an expert chomping Ghost Monster. But all Dinky has on his mind is getting an ice cream cone!

Pac-Man and Pepper celebrate their anniversary on a cruise ship. But they won't be alone as Pac-Baby and the pets manage to get onboard and the Ghost Monsters have stowed away in an effort to ruin the celebration.

After the Pacs repel a Ghost Monster attack at home, Pac-Man think he has a bad case of "Chompitis". Pepper takes him to the hospital so he can be checked out. When the Ghosts learn of this, they look to get revenge.

With the power of a remote-controlled amulet, Mezmeron resurrects a Pac-Mummy on display in the Pac-Museum. Afterward, he wreaks havoc and kidnaps Ms. Pac-Man and Pac-Baby. Can Pac-Man save them from this threat?
