The Addams Family 2 (2021)

At a science fair, Wednesday Addams is set to present her experiment, where she uses her pet squid Socrates’ DNA on Uncle Fester to show how humans can be improved (with the side effect of gradually transmutating Fester). However, she is dismayed when she sees her family show up. Nonetheless, her work gets noticed by scientist Cyrus Strange. Back at the Addams’ home, Gomez worries that the children are drifting apart from him and Morticia, so he decides to take them on a family vacation. Before the family, Fester, Thing, and Lurch head on a road trip across the United States, Gomez and Morticia are approached by a lawyer named Mr. Mustela; who claims that Wednesday was switched at birth and may not actually be an Addams, but they ignore him. On the road, the Addams family is pursued by Mustela and his henchman Pongo.

The family is initially set on going to Salem, Massachusetts, but Fester ends up making a detour to Niagara Falls. The family later stops in Sleepy Hollow, New York. Gomez and Morticia bring up Mustela and his claims about Wednesday, so Fester mentions a story when he visited Wednesday the day she was born and juggled babies in the delivery room. This only worsens Gomez and Morticia’s fears that Wednesday was switched, which Wednesday overhears.
