I don't have any items left since I used them and whenever I battle Sproink I die when he has like 10% life left. Should I use all my money on y-cola? It's all I can buy at night..
I dont remember that part of the game too well, but I'd recommend grinding a little bit or just revising your strategy. Item usage can only get you so far in this game, especially when your only option is Y-Cola. If you grind for just a short while you can raise more money as well, and obviously more money = more items (or in your case, more Y-Cola).
