If you buy the Wrath Classic Deluxe version of the game, you will receive a promotional mount in World of Warcraft (Patch 9.2.7) named Tuskarr Shoreglider. It comes with the following flavor text:
“The Tuskarr learned long ago that some of the bones of the sea creatures they hunted were light and buoyant, making for effective glider materials.”
