I wonder if it was intentional? It's really amazing just how many different rock formations there are in this remake. I know some rock formations do indeed repeat, but the vast majority are all different. Pretty amazing when you consider just how many rocks are in the game.

Yes it certainly is. In fact I was just thinking that rock would have made an interesting colossus. Or better yet had it actually been a sea turtle, it could have carried you to a secret location that would only be accessible by the turtle taking you to it. To top it off you would be forced to get the Cloth Of Desperation in order to reach the turtle as you can't swim out to where it is.

The rock you see at 0:50? Yes, I see it now that you pointed it out. There's actually lots of rocks throughout the land that resemble faces. Some could be just coincidence, but others are quite obviously meant to be a face. This was also the case in the original game too where even some of the trees had faces on them. Good observation. :)
