Surprise, surprise - Rovio's has issued the next major content update to Angry Birds Rio early! The Carnival update is now available on the Amazon Appstore (unfortunately that's the only place you can get it for now).
Here's the basic changelog:
- 15 levels in new world named Carnival Upheaval
- Blue, the Macaw, can now be used alone.
- The new hidden fruits are papaya (thanks to everyone who helped us figure this out)
Update: This update is in the Android Market now, too.
