Once you have logged on to a server, go to the town. You can see below the "Happy Anniversary" banner over the coffee shop.
Now, when you enter the coffee shop, there will be a large cake on a table.
Now here is the tricky part. Go in the upper right corner and click on the pin. It should swing down and pop all the balloons. Then the party hat will fall out of a balloon.
Now, waddle over to the hat and pick it up.
To wear the hat, click on your penguin and go to the head items. Click the down button until you find it. Now click on it, it should replace the head item that you are already wearing with your new one.
The hat looks really good when you put it on.
This year's anniversary party has sure been a blast! Make sure to get the hat today, because after 12 O'clock tonight, it won't be available. Don't forget to comment!
