Treehouse of Horror XXVI
Treehouse of Horror XXVI


October 6, 2015 - November 17, 2015

The Treehouse of Horror XXVI Event was the 17th major event and the 4th of the Treehouse of Horror events since the game's release. It was released on October 6, 2015 immediately following the end of the Oktoberfest 2015 Promotion. It ended on November 17, 2015. The Event had three different acts with a different prize track for each act.

The acts were scheduled as following:

  • Act 1: October 6, 2015 - October 20, 2015
  • Act 2: October 20, 2015 - November 4, 2015
  • Act 3: November 4, 2015 - November 17, 2015


The main quest for the first act was The Call of the Campfire, the quest continued with The Very Young Folk and The Springfield Horror in the second act. Finally, The Blameless City (and its prologue The Sandwich Horror) concluded the story in the third act.

The event included a Daily Challenges system called 'Shopkeeper's Challenges' in which the Player was allowed to complete certain tasks in order to get extra rewards in the form of event currencies. There were five challenges a week, and if the player could finish all of them, they were rewarded with 20 Donuts.

The event also re-introduced the ability to craft prizes as in past events. New items could have been crafted as each new act began, and stayed until the end of the event. Several items from past Treehouse of Horrors returned and could be crafted.

A special currency could've been collected and then released into neighbours' towns, called Formless Terrors. Players could tap these terrors in their own towns to receive currencies.

The event initially removed the Job Manager feature from the Office of Unemployment, however the feature was reinstalled with an update on October 22.

Personal Prizes

THOH26 Prize Track Indicator.png

In contrast to previous events the progress bar for the personal prizes was reset to zero each time a prize was reached. Thus only the amount of currency required for the current prize is shown there. The currency counter in the lower left of the screen still showed the total amount of currency collected, though.

Shopkeeper's Challenges

THOH26 Shopkeeper's challenges Indicator.png

Beginning on October 12th the event introduced Shopkeeper's challenges (daily challenges) every week. One challenge was added every day for the first five days of the week. The player then had time until the beginning of the next week to complete all five challenges. If they did so, they were rewarded with 20 Donuts every week they complete all the challenges.

The challenges were accessed through the House of Evil, by tapping on the icon that showed on the top right of the game's screen or by opening the fourth main tab in the event's menu.

Squishing done in player's neighbour's Springfield counted toward the required amount when performed within the first 90 daily actions.

Previously fixed at 8am local time, the new challenges were available at 7am since the last hour change on November 1st.

Daily Play Combo

Trivia

  • This was the first time the app icon featured two characters.
  • On October 20, a feature was added that allowed the player to go straight to each of the façades available during the event, as a shortcut to giving jobs at each of these buildings.
  • Hugo's questline was changed from The Good Son to My Brother's Keeper.
  • The daily challenge for October 26 claimed to have to tap 30 bunnies, however for many players they had to actually tap 30 skeletons instead. The challenge description was fixed on the 27/10 update.
  • This event marked the first time human controllable characters did not have a full set of jobs, as it's the case for every costume released with this event. However, after the event's takedown, the costumes now have a full set of tasks.
  • This event marked the first time female characters other than Lisa and Marge have costumes.
