The Party Hat (also known as Beta Hat) was a rare head item in Club Penguin. It was available at the Town during the Beta Test Party on September 21, 2005. It was the first free item in Club Penguin and players who attended the party could pick it up. It was widely considered the rarest item in the game, as it could only have been obtained legitimately in two 2 hour time spans during the Beta Test Party.
It was the first free item given away in the history of Club Penguin.
If the player talked to Sensei in the Fire Dojo or Water Dojo while wearing this, he would comment "Ahh, the Beta Hat. The most ancient of all hats. I rarely wear mine."
Screenhog designed the Party Hat. He picked what he thought were "tacky party colors and put them on a classic cone hat".[1] He chose "tacky" colors when designing the item to hopefully make the item less desirable in the future.[2]
