There is a legend of El Pollo Grande, the scariest chicken in all of Azeroth, the black chicken of death. For years he has been the stuff of myth, summonable only by Niby the Almighty during a Felwood quest chain. Now, however, he has once again returned, this time as a mount. Yes, you heard me right, a giant chicken mount. This El Pollo Grande is not as dark or mean as his namesake, instead looking like a regular -- albeit giant -- chicken and will be an epic land mount. So if you've not yet reached level 60, then consider this your motivation.
Also in the cards (see what I did there?) are an ogre pinata (which I'm surmising will be a BoP item with no charges, like the Goblin Weather Machine). Finally, for those of you who walked the Path of Illidan, there's the Path of Cenarius which leaves flowers in your wake. Nice.
