Market Mayhem

Fruit Market is an upcoming episode of Angry Birds Rio and Facebook that is involved with some deleted scenes from Rio. On the image, if you look closely, you can see three pigs on one of the buildings. This hints that the pigs will appear for the first time, or it's an Easter Egg. It is possible that this upcoming episode will debut the Pink Bird's appearance in Angry Birds Rio, making the entire original Angry Birds cast updated in Angry Birds Rio and the other first 2 games (Classic and Seasons). It might be possible if there's a boss fight with Nigel or someone else.
