i'm just getting started in metroid prime. love the game but taking a while getting used to the strafing and looking up and down. anyway, i'm having trouble with one of the bosses in the chozo ruins. it's the big plant with little directv dish-looking things that reflect sunlight onto it. it takes me about 2 seconds to blow up the 1st one, roll into the ball, and then roll down the trench and blow up a bomb. i assume you're supposed to do the same thing to the other 2 dishes, but i can't figure out for the life of me how to do it to the other two. any hints/help here?
