After searching thoroughly around the internet, I have with me an image which clearly states that the 7th Anniversary Hat, to be announced on October 24th, will be Blue and Gold. This is an image of the upcoming toy, Club Penguin Yearbook Quiz Cards.
As you can see in the image, it shows an Orange Penguin with a Blue and Gold Party hat, blowing out a cake. This is not confirmed, but I am sure that Club Penguin will reveal the Party Hat colours as this. What do you think about this Party Hat? Does it look good? Comment with your thoughts!
