Pac-Man's days as a hero don't stop him from getting tangled in a string of domestic disasters. Sent by his family on errands — fetching milk for Pac-Baby, tracking down a birthday flower for a friend of Pac-Jr.'s, and recovering his son's stolen guitar from ghosts in Pac-City — every trip somehow spirals into a new ordeal. The real threat surfaces when the Ghost Witch of Netor reveals that ghosts have been pilfering ABC gum from children citywide, then challenges Pac-Man to face her personally. He traces the operation to an abandoned factory where she has built a towering Gum Monster. Transforming into Super Pac-Man, he defeats the creature and sends the witch fleeing — though in the chaos, nobody's gum is recovered.
