Althoug in my opinion increadibly ugly
it's also one of the rather rare mounts in the game.
It drops from Ultraxion in DS and has a VERY low dropchance.
The drop is 100% the mob itself though is rare and is found in Scholomance HC in the room behind Rattlegore.
This Item has been removed from the game with the 5.0.4 patch.
One Awesome weapon espiacially for gnomes with their racial. Even better since 5.1 gave it the Extra gem.
After defeating Sha of Fear, Grand Empress Shek'Zeer and Will of the Emperor on Heroic difficulty you can buy this mount at your Guild vendor.
As of 5.0.4 this no longer drops 100% on every Heroic Ragnaros kill.
As of 5.0.4 this mount no longer drops 100% on heroic Deathwing kills.
Also it has NOT been added in 5.0.4 but in 4.3!
