## Evolution Stones

Some Pokémon evolve only when an **evolution stone** is used on them, instantly and at any level. Generation III has six: the **Fire**, **Water**, **Thunder** and **Leaf Stones** (which finish the Kanto lines — Eevee into Flareon, Vaporeon or Jolteon, plus Pikachu, Vulpix, Growlithe, Exeggcute, Weepinbell and others), the **Moon Stone** (Nidorina, Nidorino, Clefairy, Jigglypuff, Skitty), and the **Sun Stone** (Gloom into Bellossom, Sunkern into Sunflora).

Stone evolutions are a trade-off: evolving early gives you a strong Pokémon sooner, but most stone evolvers learn **few or no moves** by level-up afterward, so it pays to wait until the base form has learned the moves you want.

In FireRed and LeafGreen the four Kanto stones are sold at the **Celadon Department Store**; Moon Stones are found in the wild and occasionally held by wild Pokémon. In the Hoenn games stones are scarcer, often one-offs hidden in the overworld.
