Trivia[edit | edit source]

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.
