The Penguin Pranksters are a Terrorist Army group, generally inclined to prank the Club Penguin Moderators, simply because they can. Their biggest prank, or raid, was the 2/2/09 raid, where they formed the CP Raider Alliance, with Anonymous and RITARO. In the 2/2/09 raid, they made the Club Penguin Moderators believe they were being raided by Anonymous, when, by the 2/2/09, Anonymous had joined the raid. You may access their site here
