Not entirely sure this is from this exchange (though process of deduction tells me so) as it's not really all that horrific (though I will admit that the concept of these creatures is frightening, this figurine itself seems almost cute!).
That said, I picked it up from the post office yesterday and was rather puzzled when I opened it. Having only read the first Game of Thrones graphic novel and not watched the HBO show nor read the books yet my memory of these is rusty but I do remember them indeed and realize that they are quite horrific if you think about them that way!
So thank you! :)
