Big robot goblins?

Ok first of all Marry Christmas to everyone :D

And my question is: Every day I see some dude transformed in to robotic goblin with huge mount in center of Orgrimmar so i wonder how to get that transformation if anyone knows? :)

Extra question: Is it possible to get Time Lost Proto-Drake on Molten?

I believe it has something to do with the x-mas events. Unless you can see a buff on him/her which could tell you what kind of spell/potion/item it is.

Yes , it is possible to hunt for the time lost proto drake on molten. But you really should be lucky to find him :P
