I don't have much Frozen products either. I currently have the ShopDisney dolls (2 from the first movie (thanks eBay), 4 from the second movie (Anna and Elsa in their adventure outfits and final outfits) yeah i collect dolls, embarrassing), the Forest of Shadows book (that i have yet to read), and a Frozen II chest-like box (that's awesome). My younger sister tho (justifiably), has a lot more Frozen merchandise than i do (it was her first movie after all, pretty expected).
As for food, during Christmas, my mom bought the Frozen II cookie mix, but we haven't even made the cookies yet. Lol.
