Clapboards

 were a limited-time currency released on October 18, 2016, for Act II of the Treehouse of Horror XXVII Event. They were used as the event's Act II personal prize track currency. When Act II ended on November 1, 2016, Megaphones replaced clapboards as the event currency.

How to Obtain
could have been obtained in the following ways:
 * Tapping feral monsters yielded ten clapboards per monster tapped. Monsters that required multiple taps awarded ten clapboards per tap.
 * Tapping buildings in friends' Springfields yielded five clapboards per building tapped; however, only the first eighty-nine friend actions yielded clapboards.
 * Purchasing the Film Permit doubled the amount of clapboards a player could have earned via friend actions.
 * Clearing one's town of buildings being recorded yielded one clapboard per building tapped.
 * Leveling up the MAG Office yielded 350 clapboards each at certain levels.
