Fox has released poster art for this year's Halloween episode of The Simpsons, which takes aim at the popular Netflix series Stranger Things. Titled Treehouse of Horror XXX, the episode is oddly enough the 666th episode of the series, which the poster jokes was "planned that way from the very beginning." A short-haired and bloody-nosed Lisa Simpson is front and center on the artwork, spoofing Millie Bobby Brown's Eleven. Other alternate versions of the Stranger Things characters on the poster also include Chief Wiggum as Jim Hopper and Bart, Nelson, and Martin as Mike, Dustin, and Lucas.

Also parodied on the poster is Guillermo del Toro's award-winning movie The Shape of Water. On the top of the artwork, we can see Selma Bouvier and Kang (or Kodos) canoodling in the water, much in the same way Sally Hawkins and the "Amphibian Man" are on the official poster for The Shape of Water. Longtime fans of The Simpsons will remember Selma has a penchant for marrying various characters from the series, and it looks like one of the aliens from outer space is going to be next on her list.

The Simpsons is well-known for spoofing popular horror movies and TV shows in Treehouse of Horror episodes from years past. One classic episode was a blatant parody of A Nightmare on Elm Street, replacing Freddy Krueger with Groundskeeper Willie. In the episode, Willie attacks the children of Springfield in their dreams after Homer inadvertently causes his fiery death. Another classic Treehouse of Horror spoofs The Shining by swapping out Jack Torrance with Homer Simpson. When Homer goes insane because of the lack of beer and TV, he goes after the Simpson family with an axe. "I'm Mike Wallace, I'm Morley Safer, and I'm Ed Bradley. All this and Andy Rooney tonight on 60 Minutes!" Homer shouts when he busts through a door, clearly spoofing Jack Nicholson's iconic line, "Here's Johnny!"

Stranger Things has been recently enjoying a resurgence in popularity following the reason of its third season earlier this month. Ever since first premiering on Netflix in 2016, the show has been a major hit for the streaming service, and a second season debuted the following year. The show is now back after a wait of about two years, and its return has brought about a plethora of promotional tie-ins. This includes a literal upside-down Whopper served at Burger King in special Stranger Things packaging. Given the current prevalence of the series, it's no surprise to see The Simpsons tackling it for their Halloween episode this year.

Many fans of The Simpsons literally grew up with the series and have fond memories of watching the classic Treehouse of Horror episodes when they were younger. Even for those who've since tuned out of the series, watching the annual Halloween episodes can still be a lot of fun. Because the special episodes are now turning 30, Treehouse of Horror XXX serves as a milestone episode, and fans can see it when it airs on Sunday, Oct. 20, on Fox. For now, you can take a look at the official poster art below!
