Was this met for something?

I've been collecting items and weps and trying to unlock quest chains in mop.
I stumbled upon something weird on wandering isle. 2 out of the 4 fins on the giant turtle can be clicked on. Not sure if it is a blizz or a warmane thing, but were the fins met for something like for a quest?
Also the weirdest thing is some areas if you try to swim out, there is orgrimar and stormwind soldiers on the sea floor, but impossible to get to due to getting instantly killed if you swim too far to the bottom.
