Prism Stones

The Prism Stones are seven magical stones that ensure the survival of the Garden of Light. The Prism Stones are heart-shaped, and each is a different color of the rainbow.

Garden of Light
Five of the Prism Stones were stolen when the Dusk Zone invaded the Garden of Light. Mepple and Mipple were given the red and indigo stones, respectively, for safekeeping before fleeing the Garden of Light. They keep the stones in their tails while they have Pretty Cure recover the rest of them.

Recovery
Each of the Dark King's five servants holds a Prism Stone. With the defeat of each one, a Prism Stone is recovered, with the exception of Kiriya, who willingly gave up his stone at the cost of his own life.
