Now that I've found the Grappling Beam in Super Metroid, I'm going back through old areas to collect upgrades I couldn't get before.
One place in Norfair that really caught my attention is only reachable by grappling those invincible flying things:
Problem is, it's super challenging because you have to go airborne 4 times, grappling onto those things while they move. I've already wasted an hour trying to perform the grappling, but is it worth getting over there? What can I expect to find?
That unexplored blue square to the top right of the room is killing me!
