4th Anniversary Cake Pin

The 4th Year Anniversary Cake Pin is the 103rd pin in Club Penguin. It was made to celebrate the 4th Year Anniversary Party. After the 4th Year Anniversary Party was over, it was hidden in the Boiler Room.

Trivia

 * The colors of the pin are purple, aqua and light blue. Many penguins thought that will be the color of the party hat, though others thought it would be blue, yellow and green. In the end, it was obviously proven that the 4th Year Anniversary Party Hat would be aqua and purple.
 * The 3rd/4th Anniversary Cake pins both gave away the color of the party hats.
 * It was hidden in almost the exact same spot as the Compass Pin.
 * It was released in October 23, 2009.
