If ur wonderin' where is that last treasure chest is at, I have ur help right here. When I was playing, noticed that I just had one more chest to open. But I couldn't find it. I looked for it in every world, but couldn't find it until I found it in "The World That Never Was". If you look by the entrance to the castle, look for a ledge before the bridge to the entrance. At the end of the ledge is the last chest. Now you have found them all, end of search.:thumbup:
