The Treasure Book was a special catalog in Club Penguin that contained many different items, puffles, and coins, all of which were available to all players, and some were exclusives only found in this catalog. While anyone could view it from within the Clothes Shop or Unlock Items Online, its items could only be obtained with special codes from real-life merchandise. The Treasure Book was usually updated every several months or so. The first series of the Treasure Book was released on October 24, 2008, during the 3rd Anniversary Party, and series 21, the last series, was released on August 7, 2014.
