All-New Halloween Spooktacular! - S1-E6
Trivia: When Pietro says he'll help the twins maximise their candy acquisition, one twin says "Kick-ass!" and Wanda repeats to herself "kick-ass." Both Aaron Taylor-Johnson, who played Pietro in Avengers: Age of Ultron, and Evan Peters, who plays "Pietro" in WandaVision and the recent X-Men films, both starred in Kick-Ass.
Trivia: When Wanda, Vision and the kids are in the center of town preparing to battle their various opponents, the marquee of the theater in the background is advertising Oz the Great and Powerful. That film was directed by Sam Raimi, whose next film was Doctor Strange in the Multiverse of Madness, which itself is a sequel of sorts to this show.
Trivia: The all-white appearance of the reassembled Vision shown in the mid-credits scene is a nod to his look in a 1989 comics storyline called "Vision Quest," in which he was rebuilt without his original memories.

Trivia: Pietro makes various hellish references which tie into fan theories that what's going on in Wandavision is the work of a demon, quite possibly Mephisto: "Unleash hell, demon-spawn" and "damn it, if Westview New Jersey isn't charming as hell."
Chosen answer: The living painting is taken straight from the Family Ties intro.
