Hey Guys, today I’m going to tell you all the secrets of how to become a ninja (including how to get up to the black belt.) First off, when i received my black belt, I had to beat the sensei for the mask. So this is to all of the people who have the black belt. I know it seems that sensei is impossible to beat, but just keep facing him alot of times and eventually he will make a mistake and you will beat him. Next, this is to the people who want to get up to the black belt. You must keep playing competition mode, and try your best to win the rounds. (look under this post for the Card-Jitsu game guide.) Now, when you have beat the sensei, you will earn yourself the ninja mask! You will also get access to the Ninja Hideout:
Here’s a picture of my player card:
Besides that, theres nothing more i can tell you. Good luck to all penguins!
