The Noble Knight stamp is a medium-difficulty event stamp on Club Penguin Rewritten, which you should be able to obtain by wearing a knight costume at the ongoing Medieval Party.

Sadly, this stamp is currently broken, so even if you were a knight costume, you will not received the stamp as a reward.

The good news is that the team have confirmed that it will be fixed “as soon as possible”, so we will probably be able to get it soon!

I’ll be sure to let you know once this stamp is fixed – thank you very much for reading, waddle on!
