Ninja Mask

The Ninja Mask is an item that was released and made a reality when the game Card-Jitsu came out in November 2008.

To obtain this item, one must defeat the Sensei in Card-Jitsu. Once a player obtains this item, they will instantly gain access to the Ninja Hideout.

History
Before the existance of Sensei or Ninjas in the current Club Penguin, ninja masks were first seen in Penguin Chat 3. After Penguin Chat 3 was closed, the ninja clothing disappeared, and the ninja mask became a widely-popular myth. Originally, the rare Superhero Mask was widely believed to be the real mask, but was later proven false. When the Dojo became a newly designed room in November 2008, the ninja mask became a real item in Club Penguin.

Trivia
