Isn't the 5th dungeon in the lost hills? It should be... at least in one of the quests... You go up 3-5 times and it should be there... The Lost Hills are right next to a waterfall...
Seventh dungeon is either under the dry lake near the Fairy in the Dead Woods, or you have to burn a bush in a green bush area... I know exactly which bush... I just can't think where it is in the map... To the right of the opening screen and up a bit I think... South of Level 2... Somewhere in there.
