Here We Go!!
It's no joke, Nintendo is putting out official Beanies for the colder months this year, made to represent the Super Mario series. With Bullet Bills, Fire Flowers and more. Stylish, comfortable looking and in perfect time for the cold.Some of them are even shaped to represent characters and enemies. There's a Goomba, Chain Chomp, Boo, Shy Guy and one with Peach's crown on top. They're up for pre-order now on the Merchoid website for 19.99 : although it appears some are already out of stock.
