This is the new engineering toy coming in MoP who will give shiny gifts to anyone who speaks to him. The item has been known about for quite some time but the model has only recently been added and I haven't seen it shown anywhere yet.
What do you think? I can't say I like the silver beanie cap or that creepy smile. He is awfully shiny though!

Assembles the incredible Blingtron 4000, a robot of infinite wealth. Bling, as he likes to be called, will give out a random gift to anyone who talks to him, but only once per day.
