The fire stone, leaf stone, and thunder stone are the three basic stones in Leaf Green. They are available for sale in the Department Store. The game also includes a range of rarer, but more use specific stones. The more common example of this is the moon stone, which can be used to evolve clefairy, nidorino, nidorina, jigglypuff, and many others. The dusk stone, dawn stone, shiny stone, and a few other less useful stones are also present, but must be collected throughout the world.
