As Pac works to save Pac-World on a daily basis, we watch him navigate the challenges of being a teenager alongside his companions Cyli and Spiral. Together, the trio takes on an army of ghosts led by the wicked Betrayus, with the goal of protecting their world from harm. The inhabitants of Pac-World fear the return of Betrayus and his ghostly minions from the Netherworld, and rely on Pac and his friends to fulfill the prophecy of a round, yellow hero who will rescue their planet. Pac is the only one who fits this description, and each of his adventures revolves around his efforts to send the ghosts back to the Netherworld and preserve the safety of Pac-World.
