First, you tap on a small rock when it's highlighted, then you tap on the upside down,
open green hand.

Also, if you're talking about a large rock with cracks in it, you pick up a small rock
like I told you, tap and hold the stylus, drag to aim, and let go to fire. (^^^) 3:)

I didn't curse, it just blocked what I did call you

you just tap them like you're getting food or something, then you aim the little red
target and release
