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.
You can enter the ninja hideout when you become a ninja on club penguin, and go to other element card jitsu games (member), like card jitsu fire and water.
