I know the part your talking about.
It's actually really simple to get past this, others probably cant remmeber it because they never got stuck there. But i did, so it sticks clear in my mind.
Its VERY straight forward. The room has a pit with two platforms on either side, one platform leads to thorntail, the other to moon mountain pass. The trick is both platforms look the same. So when youve gone around, you think that your still in the same place, but in reality your on a different platform.
This isnt the only place in this game where rare uses this trick. There are quite a few areas where you will find yourself going in circles because of it, watch out for it in toher places too.
I find self deprciation is the best way for humorless people to be socialble.
