There are some new Unreleased Club Penguin Puffle Hats July 2012, meaning that Club Penguin soon plans to release more in store Puffle merchandise for you to purchase and redeem the codes. There are eight new ones. When you can get them is currently unknown, but I would imagine soon. Who knows, maybe one will be unlockable at the Ultimate Jam for Dubstep Puffle like with the previous headphones?

There are plenty of Puffle Hats you can get for your penguin between code redemptions and the Puffle Accessories catalogue in the Club Penguin Pet Shop. How many Puffle Hats do you own in total? Which one is your favourite?
