Ben and Junior Healy move to Mortville, Oregon, a quiet community, as a way to start over. Ben is initially sad to leave Cold River until Junior reminds him that everyone there has been horrible to him his whole life. Before they arrive at their new house, Junior sees a girl roller skating on the sidewalk with a balloon. He pops it with his sling shot and laughs at her as he goes by. He and Ben arrive at their new house, and moments later, dozens of women line up in their front yard, all wanting to date Ben. Meanwhile, Ben's father, "Big Ben" Healy, moves in with them when he loses all of his money in a bad investment.

When Junior starts third grade, he sees that Igor Peabody is the principal at his new school. Peabody screams at the sight of him and promptly promotes him to the sixth grade. He gets on school bully Murph's bad side when he tapes him to the chalkboard. He retaliates by trying to drop the school's satellite dish on Junior, but it misses him and hits Ben instead, knocking him out. When he comes to, he sees the school nurse, Annie Young, and becomes smitten with her. Junior, annoyed at Ben's sudden love interest, retaliates by attempting to draw a mustache on Annie's picture hanging in the hall, only to be foiled by Trixie, the girl whose balloon he popped earlier. Throughout the film, they engage in an escalating prank war.

Around the same time, LaWanda DuMore, the richest lady in Mortville, takes an interest in Ben, much to Junior's chagrin. While Ben and Junior are gone for the day, she decorates their house to impress Ben. Junior ruins a dinner she makes by putting live cockroaches in it. Afterward, she tells him that when she is his stepmother she will send him to boarding school in Baghdad. He tries to tell Ben that she is bad, but Ben does not believe him.

While at a school function, Ben sees the puppet show go awry and thinks Junior is to blame. He stops it but is surprised to see it's Trixie instead (while Junior was in the audience watching the show). It is also revealed that Annie is her mother. As Annie rushes to take her home, Ben tries to tell her he understands what it is like raising a problem child and thinks they can help one another. She tells him she likes him, but if they date, Trixie's behavior would only get worse. He proposes to LaWanda believing she is the only woman who will marry him.

By a chance meeting at a pizza restaurant, Ben, Annie, Junior, and Trixie have dinner together and a good time, even after the food fight the kids start with Peabody and his girlfriend gets them thrown out. Junior and Trixie apologize to each other and decide that Ben and Annie should date. Junior tries to stop the wedding by switching LaWanda's blood sample with that of a rabid dog. While celebrating her engagement to Ben, she gets icing on her face, which bears a resemblance to foaming at the mouth, a symptom of rabies. As a result, she is handcuffed by health department officers and sent to the hospital for observation. With her there, Junior overhears a patient in the room across from hers saying he wants to hold the world record for the longest nose. He sabotages her plastic surgery by switching the patient files, resulting in her receiving a gigantic nose – his attempt to make her so ugly that Ben will not marry her. However, she uses her funds to get last minute surgery to undo the damage. At the altar, Junior's and Trixie's work pays off, and Ben finally realizes that Annie is the one for him and Junior was telling the truth about LaWanda after LaWanda openly stated that she hates children (much to his shock). Big Ben decides to marry her, while Junior and Trixie use explosives to splatter them with the wedding cake.

The film was shot on location in Orlando, Florida from January 16 to March 15, 1991, including the then newly, opened Universal Studios Florida. The "Pizzariffic" scene was filmed at a small, vacant restaurant on Orlando Avenue in Maitland (which became Buca di Beppo two years later). The gift shop in the opening montage is on International Drive in Orlando. At another point in the opening montage, Ben and Junior get donuts from Randy's Donuts in Inglewood, California. The scenes for their house were filmed at 1216 Lancaster Drive in Orlando. When they are leaving Cold River at the beginning, they are driving down Atlanta Avenue in Orlando. All of the "Mortville Elementary School" scenes were filmed at Orlando's Kaley Elementary School. Napasorn Thai on East Pine Street in Downtown Orlando was used for the Dunmore Bank, as evidenced by the restaurant's unique inlaid corner windows visible in the scene. Orlando's Harry P. Leu Gardens was used as the "Love Rock" backdrop for the wedding scene. The Hyatt Regency Orlando was used as the "Saint Pierre Club" backdrop for Ben and Debbie's date scene.

In 2014, during an interview on Gottfried's Amazing Colossal Podcast, screenwriters Alexander and Karaszewski revealed that the studio was reluctant to rehire them, only doing so because they wanted to shoot a sequel before Michael Oliver could noticeably grow and, as the writers of the first film, could produce a script quicker than writers new to the story and characters.^[3]

Frustrated with the criticisms of the first film, they deliberately increased the poor taste, intending to make a Pasolini or John Waters film for children, and went so far overboard that the first cut received an R rating from the MPAA, a secret kept until their 2014 appearance on the podcast. Dubbing over Junior's use of the term "pussy-whipped" got a PG-13 on appeal, but the studio was still so nervous that, at the last minute, they added the 1947 Woody Woodpecker cartoon Smoked Hams to its theatrical run, to reassure parents that it was suitable for children.^[3]

The film did not fare as well as the first one, earning half as much at the U.S. box-office.^[1] Rotten Tomatoes reports that 7% of 27 surveyed critics gave it a positive review, with an average rating of 3.3/10. The site's consensus reads: "Crude, rude, puerile, and pointless, Problem Child 2 represents a cynical nadir in family-marketed entertainment".^[4] Audiences surveyed by CinemaScore gave it a grade "B+" on scale of A to F.^[5]

Variety wrote: "At times this poor version of a sitcom seems written by five-year-olds for five-year-olds, so much so that one suspects its script was fingerpainted."^[6]

The film first aired on NBC on November 2, 1992,^[7] with 7 minutes of previously deleted scenes, an altered scene (in Peabody's office, Junior burps rather than let out a long fart) and the profanity was dubbed with appropriate phrases.
