Stamp

Stamps are special rewards, released on July 26, 2010. Stamps are earned by playing games and working as a team with other penguins. There are 4 difficulty levels of stamps: Easy, Medium, Hard, and Extreme. Some are for all penguins and some are only for members. Currently, 198 stamps are available to be earned.

Stamp Book
The Stamp Book, located on your player card, is used to collect your stamps. Each individual Penguin has his/her own Stamp Book. Members are able to customize the cover of their Stamp Book, and are able to edit the color, highlight, pattern, and icon. You are also able to display your favorite stamps and pins you have received. You may only display 6 stamps and pins on the cover of your stamp book at one time. Stamp Books for other penguins can also be accessed, allowing penguins to show off their stamps. Most penguins use this feature to show the "Near impossible to get" stamps they have earned.

In the stamp book, the stamps are divided into 4 general sections. Some of these sections also have sub-sections. For example, in the "Games" section, there are sub-sections devoted to individual games. The "Events" section only had the Characters sub-section until the Party sub-section was released in August 2010.

Also, each section has its own design. Game stamps are hexagonal-shaped, Video Game Stamps are trapezoid-shaped, activity stamps are oval-shaped, and events stamps are triangularly shaped.

Pins
In addition to stamps, pins are also collected in the Stamp Book. Using the Stamp Book, penguins can show off their pins to other Penguins in Club Penguin. The pins are arranged in date of release (the time they are available). If you mouse over them, you can also see when the pins were released.
