Is the 4th dungeon the one that was robbed and destroyed by bandits? I've found the boss key in this place but nothing else(excpet a room with some money in it). A little help please. I've tried bombing out some of the walls to get to the places with rooms around them in a circle to no avail. A little help? Also, where do I find the bomb upgrades. I haven't come across any yet(and having to leave this place to go get bombs often gets annoying). Thanks.
