To celebrate the impending release of Rio 2, the animated feature about a bunch of tropical birds from Rio de Janeiro migrating to the Amazon rainforest, the free Angry Birds Rio video game tie-in will receive several content updates.

Four different episodes, each comprised of numerous levels, will be doled out over the next few months; however, the first of these planned content updates, "Rocket Rumble," is available right now on both Android and iOS.

Angry Birds Rio launched in March of 2011 and secured 10 million downloadsin under a month. The Angry Birds franchise alone earned creator Rovio $100 million in sales throughout 2011.
