Hiya penguins! You ever seen a penguin with items that you've never seen in a normal catalog, and they didn't get it in an earlier one? Well, chances are that they got it from the Treasure Book. The Treasure Book is a catalog where you can get special items with either a code(s) or key words in a Club Penguin book. Codes usually come on a real-life coin, hence the common term "coin code".
Here is a Tweet that Club Penguin said on their Twitter account!
