What is a Tsum Tsum? Marvel has the answer

As an adult who has no room in her Stately Manor for books, let alone cute fuzzy toys from Japan, I missed out on the Tsum Tsum craze. But Disney hasn't. And where Disney goes, sometimes Marvel follows so we'll have all these Tsum Tsum variant covers in August. And their own Marvel one shot, called MARVEL TSUM TSUM. Because these oblong plushies that you can stack up can have fun and exciting adventures just like the rest of us.
