You should just continue where you were going. When you get to the main elevator room (where you can go to all 3 sectors) exit, and you should find another power bomb door.
Then you have to go use a power bomb after going back to the main sector.

Ok thanks, I found it. I went by that power bomb door several times without seeing it because I was convinced that I had already opened that door. Also, is it true that you HAVE TO beat the secret boss twice in order to complete the game with 100%? That is the way it has played out so far, but I thought it was because I wasn't doing something right.
I like turtles.

The fauna storage room in Sector 1's East Side (the one with the trees in the tubes)... you know the missile balcony you can see from Search Mode from the stairs? Is the other side of the door on the C-shaped room or before that?
This. How do I get this missile tank?

Same proble as turtle a few pages ago. Proceeded and did all this backtracking through the pipes to get diffusion beam. Defeated these two worms afterwards. Everything I now find are either super missile doors or nasty slopes that prevent me from going back. Getting the diffusion beam also unlocked one door in a save room, but this only leads to another room with a super missile door. I already tried scanning all the rooms...
