Ever had that moment where you wished your mount was a lot bigger than someone else's? Well, with the right stuff.. it's possible. First of all you need someone with a Hallowed Wand - Pirate. Change stances if you got morphed in to a goblin, and you should (eventually) become a gnome or undead. Mount up, then keep switching until you're a goblin again. This should increase your mount size considerably. Drink a winterfall firewater, and it's pretty awesome.
