Club Penguin has added a new stamp that you can earn. You need to walk one of your puffles to his party room, for example if the puffle is brown, you need to take him to his room, the Dance Lounge.
There is also a new Puffle Party 2011 Login Screen that invites *only members* at the Puffle Show or invites non-members to buy a membership!!! Here is how the login screen looks like:
Anyways, it looks pretty good.
