Rovio's Angry Birds 2 partnered with UNICEF in celebration of UNICEF's Birthday and Angry Birds 10th anniversary.

The partnership consisted of Rovio encouraging players to pop as many in-game pigs as possible during the promotional window. Every Pig popped throughout the event served as a reminder that anger can be a positive force for good.

Once players popped 10 Billion pigs, Rovio donated $100,000 to UNICEF's Education in Emergencies fund.
