About a week and a half ago Megg announced that the Puffle Wild app was going to be updated later in the month. Yesterday, Friday, that update was released.
There are two new features in this update: you can release puffles back into the wild from the app and as long as you own one, you can use your blue crystal puffle in-game now too. Aside from that the app has the usual bug fixes and performance improvements. No sign of new levels quite yet!
Puffle Wild is currently available as a free download for iOS but is confirmed to be coming to Android at some point in time. The app is free (with some optional in-app purchases if you are a nonmember on Club Penguin) and can be downloaded from the iTunes app store.
