The only thing I never got about the game was:
(SPOILER):
When Palom and Porom turned into stone to save the others in the castle and you went back to them before the Giant of Babil scene, how they'd give you a box where you can use an item on them. I've heard that there's a Basilisk eye that you can use on them to turn them back to normal and get them back into your party, but that it was a dummied item. Does that item exist in the Japanese version since most dummied items were removed in the English translation, or does it not exist at all? I've also heard that you can use a game genie to get it as well...unsure.
Unsure how to make the text completely invisible like I've seen others do though...
