Here are photos of nineteen unreleased Club Penguin items! I do not know the names, costs, or availability for nonmembers for any of these items. Some of these could be in the July 2013 Penguin Style, in the My Penguin catalogue, or who knows what. I did include the upcoming Scare Games Trophy item below too. See for yourself:
Special thanks to Nicolasdc4 for the tip.
