Where Is Waldo?? (Week 7)

Where is he? Is he over here, around there, under that, or above the clouds? You never know where he can be found. I've received word he is currently at the bottom of the Atlantic ocean. But, how do you get there? How do you get to Waldo?
 Get in a giant red and white submarine, and swim down tot eh red and white corral reef. Around you will see clown fish, stores, bird sharks, and beyond! Somewhere in the crowd you much seek out Waldo. But what can you do when everything blends in with each other? All of the colors match, and he is completely camouflaged. Swimming through the rocks, go for a ride on a turtle, scour the entire ocean, looking everywhere for Waldo. He's nowhere to be found. Why does this always happen?
  It's time to head back up for oxygen when you look up and who do you see?? not Waldo... it's just a seahorse, but he's carrying a message. The seahorse hands it over, and swims away. On the soggy paper is a clue to finding Waldo...
Clue:  can be found where you least expect me... I can never be seen...
                soooo, where is Waldo??
                            In one's imagination... Waldo lives in each individual's mind...
