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 got to get the Marmosets, like the one in Jungle Escape. Sometimes, the background never moves.

Trivia

 * This theme in Rio is the first to allow the player to play with Blu without Jewel.
 * Carnival Upheaval ends with Blu finding Jewel, but Nigel finds him and tries to take him.
