Viking helmet

From Club Penguin

The Viking helmet is one of the most famous secret items in Club Penguin. Ever since the first clothing catalog, there has been a button hidden somewhere in the catalog that, when you find it, will allow you to buy the red Viking Helmet. Since January 2006, an even more hidden blue Viking helmet has also been hidden in every clothing catalog. To find it click on the Red Viking Helmet then X out. Repeat a few times.
