Carnival Upheaval

Carnival Upheaval is the fourth level of Angry Birds Rio. It has a moving background. You can collect the golden papayas along the way. The Pigs return as balloons. The last level of Carnival Upheaval is a boss fight.

The end cutscene shows a single panel of Blu flying to the parade float with the rare species caged again. The other panels show Blu finding Jewel until Nigel captures him in the parade float, which the Birds follow to the airfield.
