Rovio Entertainment has made Angry Birds Rio HD for iPad available for free this week only. It’s the App Store FREE app of the week.

What happens when everyone’s favorite fierce fowl get caged and shipped to Rio? They get very angry!

In Angry Birds Rio, the original Angry Birds are kidnapped and taken to the magical city of Rio de Janeiro, where they eventually escape their captors and set out to save their friends, Blu and Jewel – two rare macaws and the stars of the hit motion picture, Rio. Angry Birds Rio pairs the physics-based gameplay of the original game with unique twists based on the film.
