|Where found||Dojo, Given by Sensei after your progress in Card-Jitsu|
The Blue Belt is a body item that all penguins can get after beating a certain amount of penguins in Card-Jitsu (half way). It is the 5th belt you earn in Card-Jitsu which is after the Green Belt. It does not affect your ability in the game. You will receive a Postcard from Sensei telling you that you have completed half of your training once you receive this belt. Only Sensei can give you this item.
- Since the updates in May 2009, Sensei will send you a postcard when you get a Blue Belt saying that you're halfway to the Black Belt.
- Earning this Belt marks your halfway point to becoming a Ninja.
- It appears with the Yellow Belt on the Dojo postcard.
