Nostalrius Begins - Quality wow vanilla realm (1.12)

So the other day when running around in OG, i saw a guy who had Humar as pet. And not just a regular Humar. The name of the pet was "Humar The Pridelord" like the original mob, it was bigger, and it had the elite dragon border around its portrait. How the hell?

It's a bug when you put ur pet into the Stable and you rez in a BG it'll spawn the pet.
