The film opens in springtime, the year after Charlotte has died. Her three daughters, Nellie, Aranea, and Joy, are now in the stages of adolescence, with Wilbur serving as a companion and mentor.

During this time, Wilbur befriends Cardigan, a newborn lamb that is frowned upon and made fun of by the other lambs and the younger sheep of his flock because he has black wool. Wilbur takes Cardigan under his wing and shows him the farm, the ways of animal life, and dangers to look out for. However, after only a few weeks, Farmer Zuckerman suddenly sells Cardigan to another farmer, so Wilbur, along with Nellie, Aranea, Joy, and Templeton, set out to visit Cardigan and make sure he is safe; Templeton requires Wilbur to babysit his children in return for guidance.

On the journey to visit Cardigan, however, Wilbur is hungry so he gets some blackberries which make him look purple. He then gets his foot tangled in some brambles which Templeton frees him from (under the promise that Wilbur will babysit the rat kids for an additional two weeks). Some bark from the trees comes and lands on Wilbur's head. This makes him look like a wild pig. A near hit by a truck then reveals that two other guys have now seen the wild pig. This makes it hard for Wilbur to visit Cardigan.

Meanwhile, an evil fox named Farley comes and steals a hen from the barn, and Wilbur is framed for the attack after trying to stop him. Farley comes back, steals Cardigan from the barn, and plans to eat him. Wilbur now must save his friend, and does so by trapping Farley in a "pig web". Nellie, Aranea, and Joy spin the word "fox" in a spider web, and Fern arrives just in time to save Wilbur. Aranea and Joy decide to stay with Cardigan, and the film ends as Wilbur has to babysit Templeton's children.

Upon release, Charlotte's Web 2: Wilbur's Great Adventure received generally unfavorable reviews from critics. Robert Pardi of TV Guide reviewed the film saying that "This 20-years-later follow-up fails to capture the zest of the original cartoon, transforming E.B. White's beloved characters into cute sidekicks worthy of Barney. The animation is only workmanlike, and the character conceptions are as pallid as the "original" tunes". Brian Webster of Apollo Guide gave the film 59/100, stating "This is the sort of bland adventure that kids will have seen a hundred times before, with not-so-tense near-misses and not-so-exciting chases along the way." Mike Long of DVD Talk opined that "The lame story isn't helped by the mediocre at best animation. The art has no real style and could have come from any Saturday morning cartoon. The colors are good, but they only draw attention to the overall lack of detail here. For some reason, Wilbur has been given a ring of fur around his neck that keeps him from looking like the pig from the original film. Also, the Fern here looks nothing like the original. Typically, if an animated film is dull, viewers can hope for good animation to keep them entertained, but that's not the case here." Entertainment Weekly's Allyssa Lee gave the movie a C− grade, writing, "A sloppy second of a sequel, Web 2 unravels all the charm of E.B. White’s classic (not only has Wilbur become a swine who belches, but he sings about it, too)."

Richard Rowell of lifesuccessfully.com wrote a mixed review and concluded that "Overall, this film would have never done very well had it not been packaged with the DVD release of the original film. It was a direct-to-DVD film and it shows. While it makes for a cute spectacle for fans of the original story, it has all sorts of plot-holes that kill it for me. It's clear that there was some effort put into character development, and I did enjoy seeing Aranea, Joy, and Nellie come to life. They were the best part of the film for me. But overall, the film was so corny and cliched that it just can't hold a candle to the original. For what it is, though, it's OK. But unless you're a huge fan of the original story, it's not really worth watching." Jules Faber of dvd.net similarly called it "A disappointing excursion that merges old school with new school and succeeds in distancing itself from both. There are plenty of characters to amuse the children, but as far as grown-ups are concerned, this is less than plausible. Bunches of pretty colours and some beautiful backgrounds were the highlight here for me and are also sure to capture the kids’ eye for the entire 80 minutes. I’ve seen better animation in better packages, but I’ve also seen much, much worse for around the same money." Mirella Roche-Parker of michaeldvd.com rated it with 1.5/5 stars with the final comment "Who can know the minds of children when it comes to children's movies? If your particular batch of little'uns enjoyed the original, they may very well enjoy this. For my taste, it simply made me miss the original more." The DVD made a cumulative gross of $5.26 million in rental revenue and $10.23 million in its total first quarter.

A soundtrack available on MCA Records on March 18, 2003, reissued in early 2004 on Geffen Records.
