Tao Nguyen's Kida Drawing for Tab

So I sent out this sketch drawing in the mail to Tab Murphy (the screen writer for Disney's 'Atlantis' movie) as an appreciation in return for the cool signed posters he sent me.
(This sketch drawing was inspired by the underwater sequence scenes that I've worked on in the 'Atlantis' movie.)
BTW- can you guess what the symbols on the boulder reads?
