Have to trade:
A couple of things.
* Pandaren Fire Spirit
* Pandaren Water Spirit
* Any mechanical pet of yours to "rare" quality. Or I could upgrade one of my own and give it to you.
* If you don't mind waiting a few days, I'll buy you any Darkmoon pet you're missing.
If you ask me, a fair trade would be two or three of these things for the hatchling. Let me know if you're interested!
I can also give you some gold if you have a character on Thorium Brotherhood or Moon Guard.
