Theatre Masks (File:Theatre Masks.png) were a limited time currency during the Terwilligers 2015 Event. They were earned in different ways: * By tapping on Bob Clones (Act Three) that appeared on the streets of the Player's Springfield. * By tapping on Mutant Seeds that appeared on the player's town. * By completing Cecil's Daily Tasks * By completing event-related jobs at the Outdoor Opera Stage Theatre Masks were used to upgrade the Outdoor Opera Stage and to craft prizes available at the Monsarno Research.
