It has been many years since the ghost wars and no one except for Pac believes in Ghosts anymore. But when Pac opens a portal from the Netherworld, Ghosts come into Pac-World. Pac meets President Spheros, who tells him each berry on the tree of life will give him a different power, but they all allow him to defeat ghosts. The tree also keeps the planet alive so they must protect it. The Ghosts try to take the Tree of Life, but Pac eats most of them and the last ones (consisting of Blinky, Inky, Pinky, and Clyde) surrender. They think they have won until they find out the Ghosts have the Tree of Life.
