Some people need to know how to become a invisible ninja in club penguin. Well, all you have to do is click out side the chat box and push the down arrow. Some people also need to know "what odour do the gongs go in?" I don't know witch gongs your talking about so those of you that need to know please comment and tell me what gongs so I can post about it. I think your talking about the ones in the secret ninja hide-out. Again please tell me!
P.S If it is the ones in the hideout then there is no odour.
