The promotional deal is starting on the 19th January across Ireland and the UK. Customers entering participating restaurants will be greeted by the characters of the successful gaming app. Burger King will also be handing out kid's bags with every meal that will have Angry Bird themed toys and games in them. TV ads and digital content will run in conjunction to the on-site activation so keep an eye out!
I'm assuming the TV ad will look something similar to the Turkish one below.
