The Simpsons: Tapped Out Treehouse of Horror XXIV content update

The Simpsons: Tapped Out Treehouse of Horror XXIV content update is the thirty-third, and second Halloween, content update for The Simpsons: Tapped Out. The update was released on October 1, 2013, as version 4.5.0. The event finished on November 7, 2013.

2012's Halloween event saw the player squishing zombies in order to receive currency, and in this update, the zombies are replaced with ghosts. The player must 'pop' ghosts in order to acquire GOO, the currency this update. Also, this time, instead of toilet paper-ing and egging friends' houses, the player can haunt them!
