"Treehouse of Horror XXX" is an upcoming season 31 episode, expected to air on October, 2019.[1][2]


Opening sequence

In a parody mash-up of The Omen and The Exorcist, Marge gives birth to her third child, and Homer is alarmed when he finds out about his second son. Dr. Hibbert offers to swap the new born with a girl named Maggie, warning him "She tested positive for evil".

Homer and Marge bring her home, and she shows satanic powers and torments the family and the other people of Springfield. Ned vows to get rid of the evil, sacrificing her inside the First Church of Springfield, but Homer and Marge stops him. Ned however shows them the Mark of the Beast on her head, Mickey Mouse's logo.[7]

Danger Things

Set in a Springfield full of product-placement in the '80s, Milhouse (as Will Byers) is dragged into "The Over Under" dimension, where a bald Lisa (as Eleven) is sent to rescue him. A scene will feature the Starcourt Mall.[7]
