Two weeks of unfavorable weather (blue skies and sunshine) keep the Addams stuck indoors where Morticia and Gomez believe Fester and Grandmama spoil the children too much. With Hurricane Zsa-Zsa threatening the Gulf coast, Gomez and Morticia decide to enjoy it at their favorite watch spot, the dilapidated Last Chance Motel. They hire Thudd, a governess, to watch the children, which infuriates Fester and Mama over not being entrusted. They thereby divide the house in half with a white line while preparing to move out. When Thudd arrives, she seems tailor-made to the ...

Morticia and Gomez are beside themselves to understand how the annual charity bizarre could have overlooked them this year. It's for the good cause of building a retirement home, but Gomez has plans of his own for a retirement home, complete with a polo field, skateboarding ramps and tennis courts, to put theirs out of business. Simultaneously, it's Granny Frump's birthday (Morticia's mother). Morticia and Gomez have her visit so they can surprise her with a trip to a beauty spa for her birthday. Granny Frump knows something's up and, by the plans laid out on Gomez's ...
As part of the National Beautification Program, Morticia decides to avail herself as a home decorator. She needs a showcase to model her abilities. Fortunately, the Digbys, who've lived next door for only three weeks (and can't wait to move away from the Addames), are looking for a home decorator. What could be more perfect?

After the children's tongue-lashing at school for setting off dynamite caps at recess, Morticia and Gomez enroll them at Mockridge Private School headed by their "old friend" Sam Hilliard. Headmaster Hilliard's none too happy about having Addamses in his life again. Gomez takes this to mean he's under too much pressure from his board of regents, so he surprises Sam by buying Mockridge Hall, changing its name to Addams Hall and having it run "as it should be run " with courses in head-shrinking, taxidermy, do-it-yourself dentistry and demolition by dynamite.
Kitty-Cat, normally a good eater, has no appetite, leaving the family to speculate over what could be wrong. Finally they call in Dr. Gunderson, a veterinarian who is woefully uninformed that Kitty-Cat is a full-grown lion. Morticia believes the doctor's skittishness around Kitty is entirely due to a lack of self-confidence. She therefore makes it her mission to have others in the family feign ailments so the doctor can have a series of examinations followed by ego-boosting miraculous recoveries, but the poor guy just wants out.
Morticia believes they're overworking Lurch, so Gomez builds a robot named Smiley to help him out. Lurch is initially disturbed by this new situation but grows to accept it before taking complete advantage of it, relegating all his duties to Smiley. Though the family isn't pleased with Smiley's capabilities, they praise them for Lurch's sake, but perhaps overmuch. It effectively has Lurch looking at Smiley not as helping him out but as helping him right out of his job.
Uncle Fester's mishap with a new flame-thrower sets the stuffed bear afire in the Addams' living room.
