Answer 1

Here are the "steps": 1) go to the meteor herd level 2) glide to the center of the stage 3) follow the perimeter to the opposite side 4) glide to the platform witch the huge meteor on it 5) run and punch the rock so that it flies to the center, busting a metal wall 6) hit the newly available switch 7) climb the towers to get inside 8) fall to the bottom 9) claim the practically pointless but awesome item
