here is the truth! i sent an email to CP support and here is there answer!
Hey there Woodward1,
When you first activate your penguin account, your penguin name would have looked like \’Penguin\’ followed by a bunch of numbers. This is because your
new penguin name had not been approved for use in Club Penguin yet.
When a new penguin is created, a moderator reviews the name. This is to ensure that the name a player chooses is appropriate for the website. If it is deemed appropriate it is quickly changed and will appear normally the next time the player logs in.
Also, the only thing I know about the Ninja Training is that it is happening.
We will have to wait till Monday to find out all the details!
As always, please email in with any questions or comments you have in the future.
Best Wishes,
Courtney M
