During the Super Bowl game last night, you may have seen an ad for a soon-to-be-released animated feature called Rio. Cleverly tied into that advertisement was a way to get access to a secret level in that special app installed on just about every iPhone, iPad, Mac and iPod touch in the universe: Angry Birds.
If you happened to be watching closely about 26 seconds into the 32 second ad, you would have seen the infamous red bird, a golden egg and the numbers 13-12 on a wall behind a couple of characters from the movie. According to ex-TUAW blogger and current Mashable writer Christina Warren (Hi, C-Mac!), to uncover a special golden egg, you need to go to level 13-12, shoot a white bird backwards and then drop an egg (I am not making this up). Performing this arcane ritual will reward the patient Angry Birds player with a football-shaped golden egg. Completing the game level gives you the opportunity to enter a contest to attend the Rio premiere. Let's make sure it's an Apple fan (and hopefully a TUAW reader) who is walking the red carpet the night of the premiere.
Rovio, the publisher of Angry Birds, will also be delivering a special Rio version of the game when the film is released on March 22, 2011. Check out the ad video on the next page if you think that we may have Photoshopped the image seen at the top of this post.
