The landmark 30th(!) Halloween episode of “The Simpsons” will be airing this Halloween season, and rather fittingly, the episode number for “Treehouse of Horror XXX” is… #666!

We don’t yet know much about the episode but the first piece of poster art has arrived, and we can glean from it that “XXX” will spoof “Stranger Things” and The Shape of Water.

Check out the art below, while we wait for more!

“Treehouse of Horror XXX” will air on October 20, 2019.
