Hello Penguins!
The team's really excited to let you know that there will be a new set of Puffle Trading Cards coming sometime in April!! Just like the last set, you'll be able to play at home with your friends, and you'll also be able to enter unique codes in Club Penguin to build up your Card-Jitsu
deck online!
The team always loves to hear your feedback about the Club Penguin toys. We're busy working on ideas for new trading cards - and we really want to hear your ideas!! What kinds of things would you like to see?
In Other News: You've been asking, so we wanted to give you some great news about the Club Penguin DS Game which is now available (in English) in Norway, Sweden, Denmark, Finland, and Iceland! It'll be available in several places including Top Toys and Elgiganten. We're still working on getting it into Australia, and we'll let you know when we have more details.
Until then...Waddle on!
-Club Penguin Team
