Black Belt
you cant do anything until you be a ninja, then u can go in the ninja hideout!!
Nope. Sorry, but you can't be a ninja unless you're a black belt and you've beaten the Sensei.
you have to be a black belt and then challenge Sensei again to become a ninja again
the ninja black belt.
No, you can earn the black belt and the ninja mask without being a member. That would make you a ninja, so you don't have to be a member to be a ninja
You keep playing Card Jitsu in the Dojo. When you get to black belt, challenge the Sensei. If you win, he will make you become a ninja and you will get a ninja hideout!
Level 31 is your first black belt
Yes they can, but you have to be a black belt and you have to be a ninja. I think you have to dance with your ninja mask on in the Ninja Hideout to become invisible. Good Luck!
