Till now, card jitsu snow has not been released. Therefore it is currently becoming a snow ninja on real Club Penguin is totally impossible.
nope you need to get black belt in card jistus and fight sensie then you become a ninja and then ppl will not be your friends they will kill you at Halloween bwhahahahahahaha jk
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.
you talk to sensi and if you beat him at card jitzu you will become a ninja you talk to sensi and if you beat him at card jitzu you will become a ninja
become a ninja. I became a ninja but nothing happened.
Once you become a ninja you get a ninja mask and gain entrance to the ninja hideout. Once you are at the ninja hideout you can buy ninja clothing and furniture, train to become a fire ninja or a water ninja. Or just play other ninjas in regular card-jitsu.
you can't unless you get a membership card
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!
You keep playing Card Jistu with someone else until your a black belt then you play sensei (it will take a while to win) that is the only way to become a ninja
If you have the Amulet, and you can become a Fire Ninja, buy Club Penguin Card-Jitsu cards in real life. If you find a Golden Card, you have the choice to earn 6 more cards, or skip a level. If you select skip a level, you get a free piece of the Fire Ninja costume. Also, you can do this with Card-Jitsu Water, and regular Card-Jitsu. Except with regular Card-Jitsu, you earn a belt, not a piece of a Ninja Outfit.
You can play Card-Jitsu at the Dojo,and if you're a ninja then you can also play at the Ninja Hideout.
Play Card-Jitsu until you get a black belt and then loose against sensei about 7 times until he makes a mistake, this is when you can beat hi and become a ninja.
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! :)
