someone posted in daz forums also and another replied it was a custom morph, not sure about the accuracy of that as the only person who would know is the vendor who did the promo. 

I agree with the lack of credits in their store, maybe it is available in another store and hence the lack of link (or advertising)

I'm sure someone will find it if it's available, (I will have a look around but I'm useless at this sort of thing) but there are people who find anything and everything here.
