The Night Ninjas army is a new army to Club Penguin. Some say they are a really old army that came to Club Penguin a few months ago. No one knows their true legend. The leader of this army is unknown. Their website is http://nightninjas.blogspot.com/
So far they have conquered 5 servers. They are:
- Ice Palace
- Hot Chocolate
and they lost those servers, as Dark Snow captured them. They lie in shame.
The army would appear to be dead. Their website contains one post, dated February 3rd 2012 that says it will be shutting down "temporarily."
