On March 17, Angry birds will show us their Irish side in a new episode to celebrate St. Patrick's Day. On that occasion, the green pigs will wear green hats while the birds will continue doing what they do best in the game. The preview trailer shows no major change in the graphics except for the St. Patrick's theme of course. This edition is called " Go Green, Get lucky" and will be a free update for IOS, Android, WebOS and Symbian. Watch for the update notification on your device, March 17 is just about a week away.
