There has been a last-minute-updated from BillyBob about the Tresure Book!!! And this last-minute-update will bring joy to everyone!!! Well, this book was made so that penguins can buy items that weren’t always availible or never-released. And cause Christmas is coming, the CPT thought that it would be good to put some Christmassy Items into the Tresure Book.
So starting on/from Friday, December 5th, you will be able to use the codes you got from the Club Penguin Toys to unlock some items in the Tresure Books. Im not sure if you could already do this, but yeah 
and the items still in the book will still be in the book and the new Christmas Items that come.
