This is the 34th Treehouse of Horror episode, and, like the other Treehouse of Horror episodes, consists of three self-contained segments: in "Wild Barts Can't Be Token", Bart turns into a non-fungible token and Marge enters the blockchain to rescue him; in "Ei8ht" (a parody of Mindhunter), Lisa seeks the help of Sideshow Bob to track down a serial killer; and in "Lout Break" (a parody of Outbreak), Homer eats a contaminated doughnut and starts an outbreak, turning others into versions of him.

The episode was directed by Rob Oliver, and written by Jeff Westbrook, Jessica Conrad and Dan Vebber, one writer per segment, featuring guest voices from Kelsey Grammer, Kylie Jenner and Matthew Friend.

After telling Marge, she enters the blockchain to rescue Bart with the guidance of "enlightened intellects" Kylie Jenner, Rob Gronkowski and Jimmy Fallon.

After Marge and Bart return to the museum with Jenner's key, it is revealed that Homer turned himself into an NFT during Burns' offer.

In an alternative ending to the fifth season episode "Cape Feare" (1993),[1] Lisa watched Sideshow Bob brutally murder Bart on a houseboat drifting from Terror Lake to Springfield.

Thirty years later, in a parody of the David Fincher series Mindhunter, a traumatised Lisa has become a renowned criminal profiler.

She is called upon by Springfield Police Department Officer Nelson Muntz to help investigate a series of murders with messages of the victims' names followed by "was the first" scrawled in blood.

Seeking help in a Hannibal Lecter-style riddle or anagram from an imprisoned Bob, he instead mocks the idea as a plot cliché and provokes her wrath by bragging in a crude limerick about the murder of Bart.

While he is complaining about society's unfair rules, a doughnut falls off and rolls, collecting dirt and nuclear waste, but Homer runs after and eats it anyway.

The virus spreads worldwide via belching, filling the entire planet with a chorus of Homers singing "Just Like Paradise" by David Lee Roth.

Jeff Westbrook, Jessica Conrad, and Dan Vebber wrote "Wild Barts Can't Be Token", "Ei8ht", and "Lout Break", respectively.

Kurland praised the following sequence's plot structure as "the only horror-centric" part of the episode, but felt it was unfitting for a return of Sideshow Bob to the show.

[9] Hindustan Times's Tuhin Das Mahapatra opined that the episode's approach to contemporary topics like NFTs felt outdated.

Das Mahapatra considered "Ei8ht"'s plot as being more sinister and exciting and a "welcome change of tone" from the first segment, while also enjoying the humorous nature of "Lout Break".

Boyle expressed satisfaction with watching Lisa getting "to be unapologetically evil for once" as opposed to her portrayal as "a victim or observer" in other Treehouse of Horror episodes.
