Where is the treasure book on Club Penguin?

You can look at the treasure book by clicking on toys and then treasure book, but you can't unlock anything in it unless you have a code from a toy. When you do have a code from a toy, and when you are first logging on, click on the unlock item button. Click on toy, and enter the code you get on your toy. Sometimes it depends on what toy you get. from there, you can unlock anything you want in the treasure book.
