I used it a few times to avoid having to backtrack. Useful as a time saver.I say the Farore wind,this item is SO useless,I never use this item once(exept the first time to see it)it can bring you back to the room where you used it but its so pointless,its not like the dungeon were so long that you need to keep you location if you most turn off your N64,you can just save your game and return in no time and continue.
Actually that one is quite useful if you get it before Bongo Bongo as it makes it very easy to beat him.Hey guys! Whats the most useless item in the whole series! Mine is the ice arrows from ocarina of time. Whats your pick?
