If you are not a Ninja yet or do not know about the Secret Ninja Hideout Room, then keep reading. When you are finally a Black Belt, and you have beaten Sensei, you get entrance to a Secret Room near the Courtyard, just have a look at the Ninja Hideout/Room for now……….
To get into this room, there will be a door near the hut on the left, ignore the fact that there is no door in this picture, but if your a Ninja and have beaten Sensei, there will be a door…….
In this room, you can also play Card-Jitsu on the mats! Another thing is by clicking the catalog or going to the shack that’s high-lighted, you will open up a Ninja Catalog, which will have Ninja Things. Unfortunately they are all Member Items 
If you can buy ‘em, there’s a Ninja Outfit (which does something special, will be revealed below), a Dojo Igloo, Rice Paper Wall Screen, a Stone Lantern and a Hand Gong.
That all adds up to 7475 coins!!! And now, I was talking about that the Ninja Outfit does something special, well if you wear it and when you dance (D) you become Invisible or Transparent 
. Look here………
And the Hand Gong does something aswell!!! If you hold nothing else but that and Dance (D) you will bang it and will make a Gong-Sound!
Here’s how the Ninja Outfit looks like on a Profile Player Card (not including the background or the pin). The Mask will be in the ”Face Items” and the other part of the Outfit will be in the ”Body Items” where your Black Belt should be…..
Don’t worry Non-Members, you still get that mask that the penguin on the stairs is wearing!!! Anyways, if you want to see the Catalog for yourself, or if you want to listen to the Dojo Room Music, go to these SWF’S…….

Edited Post: Rawk I edited a lot of that post, please dont go getting Ojoc’s work even if he gave you permission for you to use them, I don’t like using other peoples work, but thanks anyway
This isn’t working for me
And I’ve already seen you but you didn’t see me 
But you were going to Card Jitsu so I think that’s why you didn t see me.
Club-Penguin-Pins: Oh! Well if you want to meet me again email me because I see comments late!
Sorry CPP
I couldn’t find out how to do it myself….. im so stupid…..
Club-Penguin-Pins: No No your not stupid, you just need to learn how to do it
Don’t worry, i’ll teach you. Besides your just a beginner.
Srry if i done something bad
Club-Penguin-Pins: You haven’t done anything bad, just remember that for next time
So I can’t help you?
Club-Penguin-Pins: Help me with what???
Well now whit nothing, but like whit this black belt HQ.
I never get a belt
Club-Penguin-Pins: Don’t worry you will eventually!!! Don’t and Never GIVE UP!!
I have my Black Belt, but I automatically lose to the Sensei. He knows what I play next still, what do I do to beat him?
Club-Penguin-Pins: This happens to every Black Belt. Just keep versing him about 10 times and then after a few rounds he will start to play fairly.
