The Tree of Life is the tree that Power Berries grow on. They provide powers for Pac. Pac also owns a smaller size tree that also provides Power Berries. The Tree of Life has been stolen by the ghosts on a couple of occasions in Betrayus' quest to undermine and conquer Pac-World.
The tree provides a variety of berries indicated by color. Power from the tree's berries include fire, ice, titanium, and chameleon among others. Some of the berries picked from the tree are genetically engineered by Sir Cumference to provide some of the most unique powers.
