Club penguin is an online chat site. You create a penguin and chat to other penguins. There are also games to play, and clothes and furniture that you can buy to decorate your igloo, which comes free with your account. Unfortunately, only members can buy things, other than items marked for everyone, or red and blue puffles. Puffles are little furry fuzzballs that the penguins keep as pets. There are also PSP and DS games for Club Penguin. These are games about the secret agencies in Club Penguin. The PSA (Penguin Secret Agency) is the agency that isn't really secret anymore, and the EPF (Elite Penguin Force) isn't really secret either, even though they pretend it still is. The PSA HQ was destroyed, but the EPF still exists, and can be joined if a penguin sends you an application postcard.
