What is it?
I wonder what could be in there? Hmm... do you think it is safe to explore? Better make sure you are safe before jumping into the deep, dangerous waters. A full dive set should do the trick. Make sure you have your wetsuit, oxygen tank, snorkel, and flippers before you go too deep.
Note: DO NOT wear your dive gear on your Human Avatar, or it will not work!
It simply needs to be in your Closet.
