Getting a moon rock is actually pretty simple, but you need to be in kanto. Go to mt. moon in the EVENING and climb to the top, when you go beside the "store" you will see clefairy's dancing. simply walk over to them, and they will all run away. but one wil drop a moon rock.
You need to trade it with a Pokemon from LG or FR,
you need AR to do it
Any Pokemon able to learn the HM strength can move boulders. To shatter rocks you need the HM Rock Break.
jiggilypuff evoles to a wigglytuff but you need to migrate the Pokemon
you need rock climb
you need the hm rocksmash.Once you have it teach it to your Pokemon. then press A to a rock(only breakable rocks plus you need the Pokemon that knows rocksmash in your party.It may not work until you get another gym badge):)
If you are playing the main Pokemon games, you will need to teach one of your Pokemon the TM/HM Rock Smash. (In Pokemon XY it is considered a TM) In Pokemon Ranger: Shadows of Almia it is taught at the beginning of the game that you will need a Pokemon that have the ability to crush rocks. Bidoof is one of the beginning Pokemon as an example.
