An NPC named Robin has been found. WoWhead, asite that scours the game code for new additions, picked up three instances of the tribute in a recent update for the Warlords of Draenor beta build - a male human, a female human, and a blue genie.
This model has been used before as a boss in a dungeon, but the idea is that this version of the model will most likely transform into other Robin Williams' characters.
This morning near Ketchikan, Alaska a sea lion was hiding under our fishing boat because he was being stalked by a killer whale. When we decided to leave the area the whale attacked the sea lion and tossed him 20 feet into the air!
