Party Hats, in addition to pins, are the only items that will never return on Club Penguin – once it’s gone, it’s gone. There is currently a total of seven party hats – one for each anniversary party on Club Penguin, and the original Beta Test Party Hat from September 2006.
This is the Beta Test Hat, released for only a few hours in September 2005. It is Pink and Yellow. This is probably the rarest item on Club Penguin as hardly any penguins have it.
The First Year Party Hat was on Club Penguin for a day, released in the Coffee Shop in Club Penguin on October 24, 2006. It is Blue & Green. It is not that common of a hat, but it is most common than the Beta Hat.
The Second Year Party Hat was to celebrate two years of Club Penguin. It was released on October 24, 2007.
The Third Year Anniversary Hat was three colors since it was their third year of operation. It was released on October 24, 2008.
The Fourth Year Party Hat was added on October 24, 2009. It had two colors – purple and blue.
The Fifth Year Party Hat was released on October 24, 2010 and has a total of five colors on it.
The Sixth Year Party Hat was released on October 23, 2011, a day early.
The Seventh Year Party Hat was released on October 24, 2012. It is the most common party hat.
