I noticed that in the NE segment of this stage, there are two rooms that are blacked out. Both rooms have exterior walls with large cracks in them. I don't remember seeing these cracks in any of the other walls. Are these just red herrings? They remind me of the old walls in the Legend of Zelda where you could explode bombs and gain entrance. Any ideas on this subject? Or is it just my overactive imagination flaring up again?
