UPDATE: These items have been released in the My Penguin app.
When Club Penguin updated the game last night they accidentally(?) made public three different unreleased clothing items. There is a hand item, a body item, and a foot item. When these items will be released is unknown. All three items are members only.
There is the Green Satchel for 300 coins.
The Puffle Hoodie for 450 coins.
And finally the Gold Sneakers for 250 coins.
