Hi, terribly sorry if this has already been asked, 38 pages is a lot to read and I don't like using walkthroughs unless I'm incredibly stuck and have no idea what to do.

I'm playing Link to The Past for the first time, and I can't seem to get the special bombs at the bomb shop

and another thing would be I'm in the dark world going to fight the 3rd boss and I made it all the way to the head of the beast in the woods but now I don't know how to get to the boss, or finish the holes in the ground.

any help would be amazing. Thanks ^^
