There are 4 moonstones to be found in Pokémon blue. These four stones are used to evolve four different pokémon into their final forms. Nidorino -> Nidoking Nidorina -> Nidoqueen Jigglypuff -> Wigglytuff Clefairy -> Clefable
you can find a few in mt.moon. just search throughly. -RR14
There are 2 moonstones that are findable in LeafGreen. One is found in Mt. Moon, while the other is found in the Rocket hideout. Additional moon stones can be found on wild clefairy.
There is a store where you can buy moonstones, use that.
Nobody has figured out how many there are but you could look it up in action replay and see if there is a cheat.
Moonstones are evolution stones for Normal-types. Use them on a Jigglypuff, or Clefairy. Other Pokemon use it too, but I can't think of them right now.
