Two places where I'm flummoxed:
1. Opening the gate to the star in the Volcano -- the one in the area that's green-gated off. I saw that someone mentioned looking in the heavy lava area, but I've been poking around everywhere to no avail.
2. Getting past the icicles that block off the missle pack and one of the stars in the Ice Cave. I haven't seen any other posts about this, so I'm wondering what I'm missing. I have all four guns and plenty of missiles. Is there some extra equipment I need?
