How do you evolve a Pokemon with an item in Pokemon LeafGreen?

Answer 1

Only some Pokemon evolve using certain evolution stones: Water Stone, Fire Stone, Leaf Stone, Thunder Stone, Moon Stone. For Example: Clefairy and Jigglypuff both evolve when exposed to a Moon Stone. To evolve a Pokemon that evolves only from exposure to a evolutionary stone first you need to get the stone the water, fire, thunder and leaf stone can be purchased at the Celadon City Dept Store, you only get 4 moon stones in the game so use them wisely. Second you need to go into your Bag scroll to the stone press A and choose Use choose the Pokemon that says Able then press A and now your Pokemon will evolve. Here are the kanto Pokemon that evolve by stones: Clefairy, Jigglypuff, Nidorino, Nidorina, Exeggcute, Vulpix, Growlithe, Evee, Pikachu, Vileplume, Staryu, Shellder, Weepinbell.
