Ok - I searched and found the answer about how to do the quest Oka's Chest. So I went inside the Grand Arena and stood just inside and waited for the code to appear. But no code came. I scooted up a few inches and still no code. I tried and tried and could not get the code to appear. Any thoughts?
First of all, standing at the entrance of the Grand Arena won't help. You need to go into the Mander's Trophy Room (all the way straight, turn left and go to end). Go inside and solve the puzzle. When you enter the 3 stone tablets on the far side of the room show the answer and the disappear when you move. I'll give you a hint, 1 is part of the world's name and the other 2 shine.

As seethe42 explained, you see the code when you enter the Mander's Trophy Room, not just the Grand Arena. If you still have the quest "Trophy Quest" to use Oka's Chest, then your Quest Arrow Helper should point you in the right direction.
Once you enter the Trophy Room, just stand still, and you will see "yellow banners" appear on the back wall in that room. The clues you need are on those banners. If they disappear before you make a note of what the clues are, just leave the room and come back in. The banners will reappear for a short time again. (If you approach and read the book in the center of the Trophy Room, that is basically what it tells you.)
Once you make note of the clues (something like a crok head, etc.), then you go to those obelisks in the center of the room and light them up.
That will make Oka's chest appear and you can interact with it.
