I missed a bag in my previous bag post. The bag is from this brand called Nyanko Burger by the company San-X. I bought it at AWA, Anime' Weekend in Atlanta, (an anime' convention). I also bought the Pocky bag at the same time.
I found this cool website that sells a wide variety of Nyanko food plushies. Check it out here! There's a cute mug here, and the updated site is located here.
