It appears that Club Penguin mistakingly released eight item files to the public even though they are not yet readily available in Club Penguin yet. However, Club Penguin Tracking has obtained these exclusive unreleased Club Penguin item images and would like to share them with you. These items will most likely be released at the Make Your Mark: Ultimate Jam 2012, which starts two weeks from now on July 19th. Below are images of all the items as well as the corresponding image name.
