In this episode, Maggie is possessed by a demon, Lisa finds an alternate reality where people have buttons for eyes, and Homer starts eating himself.

On a pre-Christian temple site in northern Iraq (a parody of the opening scene of The Exorcist), a Pazuzu statue is dug up and sent through Amazon to the Simpsons home due to Homer accidentally ordering it, thinking it said "pizza".

In a parody of Coraline, Maggie is still recovering from Pazuzu while starting to violently vomit all over the dinner table, eventually flooding the kitchen.

In Lisa's room, Snowball V (voiced by Neil Gaiman) takes her through a secret tunnel that brings her to another version of the family that have buttons in place of their eyes.

While the alternate family are like a dream, Lisa runs back to the real world in terror when she learns they want to sew buttons over her eyes so she can remain with them forever.

He discovers how tasty it is, losing interest in other food when invited by Ned for lunch, and starts cooking parts of his body before his family come back.

They become suspicious with Homer constantly wearing oven mitts to hide his severed fingers, being 20 pounds thinner, and walking with a limp.

With the first two segments parodying the films The Exorcist and Coraline, executive producer Al Jean wanted something scary and original for the final act.

Jean was worried the story would be too extreme but received approval from executive producer James L. Brooks and actor Dan Castellaneta.

The producers wanted Lisa to sing Leonard Cohen's song "Hallelujah" at the end of the segment but were unable to secure the rights.

Club gave the episode a B− stating, "The 28th 'Treehouse Of Horror' carries on the venerable Simpsons institution by, as ever, tossing a whole lot of stuff at the screen and seeing what sticks.

Freed up from the need to calibrate the heart-yucks equation, a 'Treehouse Of Horror' rises or falls on the strength of its jokes, although the annual Halloween anthology provides its own unique degree of difficulty.

The series finally plugged two major holes in its huge collection of horror movie parodies while also reminding us that it can offend and disturb with the best of them.

"[8] Tony Sokol of Den of Geek gave the episode four out of five stars stating, "'Treehouse of Horror XXVIII' had chills and spills, which Marge, of course, has to clean, but the thrills were only middling.

It took chances, like leaving a kid alone with a catholic [sic] priest, but ultimately doesn't reach the dizzying highs, terrifying lows nor the creamy middles of Halloweens past.
