The Great Ninja vs. Agent War is the large 2010 summer-lasting war that changed Club Penguin forever. Agents watched out for Ninjas and Ninjas attacked EPF countless times. For the Ninjas of Outback the final battle (the EPF's alamo of July 29th) was a revalation. The Ninjas relentlessly attacked full-force (50 Ninjas) and conquered EPF. The Ninjas of Outback never attacked them after July 29th because they were now considered a minor threat.
