If you go to the Dock from May 1st to May 7th, you should see the Funny hat Week Party... it's a small event, supposed to resemble old CP. FYI, it's not at the Beach, but the Dock (the Club Penguin Times made an error).
Lot's of free hats and one background... (Click the camera for the background and the hat busts for the hats.)
Thanks to Master Flap for these pictures!
