New EASTER EGG found

I'm the type of person who searches games, from the very top to the very bottom, for every easter egg that can be hidden. With that said, I've discovered a cool new easter egg.

Bored one night on my alt in the Barrens, I got the idea to go around searching for and killling every innocent Sickly Gazelle in sight.

After what seemed about 45-50 kills, one of the Sickly Gazelles was all shiny and sparkly, like it had dropped some loot. In disbelief I clicked on it and sure enough was a [Sickly Gazelle] pet.

Now I've never seen anyone else with this pet, so I think it is pretty unique and perhaps an easter egg?
