Hey guys, as a few of you may have known, the ad for the movie Rio had something about a secret level in angry birds. I found something on it.
In this image, you can see the red bird and the golden egg. Under it is written 13-12. This is a screenshot from the trailer. I’m still not sure HOW the level is unlocked, but you guys can probably find something out of it.
The level has been found. I got mentioned on The Daily What too! =D
