A purple dolphin would be an amazing sight to see. I've heard that albino pink dolphins exist so maybe, just maybe there's a rare purple one out there somewhere. :D
hey, anything and everything comes in every conceivable colours now, don't you know? if there's bacon flavoured ice cream, which i oppose, why not a purple sea? especially if there's a red sea if you combine it with the atlantic which is deep blue, you just might get a purple sea. (okay, i know the red sea is not really red.)
