In the beginning, they did a fish / gnome in a murloc in war 3. They merged fish with night elves and gave us naga. In Wrath they used walruses and gave us tuskarr. In MoP they did fish again and gave us jinyu. Would you like to see Blizzard anthropomorphize another sea animal and what would that be? Sea otters? Badgers? jellyfsh? octopus?
