So I've tried everything when trying to equip a bottle, shield, etc. but nothing works. I have looked everywhere an tried everything I can think of. I've searched google watched walkthroughs. So I've went the whole 9 yards. Before you try and tell me use the minus button I have a dozen times. The mini button is like it was the very beginning if game it's blanked out so you can't use it yet. I'm to the point in the game where I have to feed the thirsty frog and I can't continue in the game unless I can find away to equip a bottle. Could this be a glitch or something?
Go to the Item Check to see if your pouch contains the Cursed Medal. If so, remove it and put it in storage, and you'll be able to open your pouch again. If not, then there must be some sort of bug involved, and it's not one I've heard other people have.
