Treehouse of Horror XXIII Event

The Treehouse of Horror XXIII Event was a halloween-themed event released on October 12, 2012. The event contained several new limited time Treehouse of Horror characters, decorations, tasks, and buildings. Along with the update came several new standard buildings, decorations, and characters such as Edna Krabappel and Otto Mann. There was a different way to vandalize other players' Springfields during the event. It ended on November 8, 2012.

The Treehouse of Horror XXIII Event also included a social side - players could visit their friends Springfields and vandalise buildings with Toilet Paper and Eggs. When the player vandalised homes, they would receive one treat; if a player cleaned the toilet paper or eggs from a building they could collect a treat as well.
