About three weeks after Club Penguin started, Billybob posted something about adding Ninjas! A few weeks later, Secret Agents were added to Club Penguin. The post about ninjas was deleted but not their mystery. The Club Penguin team has still left us a bit of ”ninjas” around…like:
Also, on the old website, there was a banner and if you touched the ”N” in the word Night Club, the blue penguin would become a ninja.
As we all know, the Dojo is the home or the hidding place of all the ninjas. There have been a couple of things proving tha the Dojo is the Ninja Head Quarters like…-In the history of Club Penguin, the only place where you could walk on walls was in the Dojo, we all know ninjas walk on walls 
[April Fool's 2007 & 2008]
-The Dojo is a wooden structure with layers of design, much like the temples where ninjas are in the movies. hehe
-There was the ninja egg in the Dojo [Easter Egg Hunt 2008]

Here is a picture of what a ninja in Club Penguin looks like:
Apparently, Club Penguin will release the ninjas [for you to become them] but they have not yet and will not in a very long time. Let’s just wait some time till this happens!

Theres a ninja at the iceberg…

Sportboy5748: I’m glad you like my site!
BlUeSoUl: Thanx for telling me
Also, I’m not sure the one from the petshop is a ninja, but you gotta admit they look like footprints! 
Wow, I have never seen the one on the Pet Shop.
Limeboy – Well Firtula isn’t sure if the one on the Pet Shop are foot prints of Ninja’s. And I don’t even think they are one bit. Its technacilly just the shape of the snow. But maybe Firtula’s right. But still, Ninja’s, On A Pet Shop? That’s Kinda hard to believe.
P.S. Sorry If I Have Anything Rude Or Mean In My Comment. If I Do Please Remove The ‘Word’. Thanks
Daisey4848 – You’re entirely right! I’m not really sure if those are footprints…but who knows…
And abut the comment, I don’t find that rude at all, you’re just speaking your mind and I love it when people do that, so keep telling me what you think on everything! 
Now, if you all go to the site that I mentioned, you can really be a ninja!
