well what kind of rocks is it? does it say a pokemon can break them that means u need the HM rock smash. if it says that a pokemon can move them u need the HM strength. if u have the hm u have to teach it to a pokemon (caution: if i was u i wouldnt give it to your starting char because hm can not be forgoten)
PS u can trust me i have been a pokemon fan from the very beginning (red, blue, yellow)
PPS i would tell u where to get the hm but i forgot srry.
PPPS if u get stuck again u could go by the guide at wal mart.
well happy playing
^.^
