The Snow Queen

I'm watching the current episodes of Once Upon a Time at Hulu and there's a new character - the Snow Queen. When I think of her I always remember the drawing by HJ Ford in the Pink Fairy Book. I once had all the differently colored fairy books and loved the art and the stories. But anyway, there's also a reindeer in this storyline ... I guess some of this is from the Disney movie, Frozen? ... and he we see Anna, the Snow Queen's sister, and her intended, Kristoff, and Sven the reindeer :) ...
