On Club Penguin, When you become a black belt, do you have to do Competition or Sensei mode to become a ninja?

I became a black belt but I tried doing Sensei Mode a lot of times but hes not losing. Am I supposed to do Competition Mode first to Become a Ninja?|||to become a ninja, select sensei mode and you will play him. it is impossible to beat him the first few times, but after you lose a lot, he will get weaker and you can beat him











trust me, i am a ninja myself!|||Yes, you must beat the evil sensi. :)





Although that is imposible without a black belt. otherwise he is physic and use ice when use water. You use fire he use water. You use ice he uses fire. So get a balck belt first!!





Hope this helped!!!!|||yes you have to beat the sensei to become a ninja and get the ninja suit after beating him|||you have to compete against sensei a lot and then he%26#039;ll start loosing
