Trivia[]
- Most of the event’s theme and new content is based on Season 5, Episode 5 “Treehouse of Horror IV” segment “The Devil and Homer Simpson”, Season 24, Episode 15 “Black-Eyed, Please” and Season 26, Episode 4 “Treehouse of Horror XXV” segment “School is Hell”.
- The update brought a few changes with it:
- The item limit was increased by 1000 items in Springfield going from the cap of 13000 to 14000 items.
- Alcatraaaz's 60m job "Raise His Sneaker Game" and 8h job "Enjoy His Financial Security" requirements were fixed.
- The locations for the freemium characters' currency tasks was changed back to Springfield Elementary or Brown House instead of the Heights Theater or Brown House in the Sidekicked Aside questline.
- A patch update was released on October 15 which included some more changes:
- The music was changed to the Treehouse of Horror music for the event.
- Leaves fall on the screen.
- Rivers were changed to the darker versions from previous Treehouse of Horror events (excluding the XXIV and XXV events which were different to the darker river).
- The loading screen illustration has a coloring mistake, giving Beelzebart and Lisafer's legs their usual yellow color.
