I’ve got some information on a few unreleased items! There is a new pin called the Pink Mystery Pin. It’s a pink version of the Castle Pin, which is unlockable via a special old code from Disney. I do not know how this Pink Mystery Pin is obtained.
There is also an upcoming unlockable item called the Elite Body Armor. I do not have an image of this item.
Finally, as you might recall, I had previously posted about this item. I now know its name – the Hazard Suit. This item is unlockable too. From what, I do not know.
