Carnival Upheaval

Carnival Upheaval is the 4th level of Angry Birds Rio. It has a moving background. You can collect the golden papayas along the way. The Pigs return as balloons. In Level 8-15, you've gotta get Mauro, the king of the Marmosets. Again, you've gotta get the Marmosets, like the one in Jungle Escape. Sometimes, the background never moves.
