When you become a ninja on Club Penguin, you are allowed to go into the Ninja Hideout. There you can access an exclusive shopping book. In that book you can buy Martial Arts related items, for your penguin and igloo. In the Ninja Hideout, you can also access the water and fire dojos. You can beat those to become a ninja in that element. If you choose not to take on the water and fire challenges, you can just play regular Card~Jitsu with other ninjas! If you do not want to do any of this, there are some gongs you can throw a snowball at to have a little fun! :)

you cant become sensei but you can be a ninja
You can't yet.
No, not really. You can become a master ninja on club penguin, but not a Sensei.
You can become a ninja faster by earning the belts and fighting people more.
You can't. You have to be a ninja and a member to be invisible.
