What is the DEAL with this room? First you need super missile for the door. Then the wall inside it needs a power bomb. Then the wall behind THAT is a speed booster wall. But there's not enough space to get a run-up, so you apparently have to do some shinespark magic by getting speed in the room before it. So you have to somehow get speed up in the first room, store it long enough to reach the second room, lay a power bomb (fucking power bomb blocks aren't one-time-only), then shinespark through the second wall.
Not even a power bomb or energy tank is worth this level of insanity.
