When Bentley comes for his annual visit to the forest, Bert and Cedric take him to see the old Evergreen Schoolhouse. There, they meet their old teacher, Ms. Primrose, and learn the school is too small for government regulations, and must be closed.

Cyril is taken ill and is advised to retire. Cedric is intimidated into sponsoring a televised sports event by a very shady character. Lisa and Bert fall out while training for the events, and too late Cedric discovers the scam he's walked into. It's up to the gang to win the event, or Cedric loses one million dollars.

Sneer needs a product to sell to Mammoth and puts Cedric in charge of the factory. The product is a failure, but a trainload of garbage arrives at the Forest and sets Cedric to thinking about recycling plastics. A new business venture is born, while Ralph learns the unsettling truth about the source of the rubbish.

When searching the family archives for one of Lady Baden-Baden's literary projects, Bert and Cedric find papers for the adoption of a Sneer and believe Cedric has been adopted.

Ralph's brother George moves into the Evergreen Forest with the rest of his family. George has been offered the job of presenter of a cooking program on K.N.O.X. TV. The pigs try out a career in television after being fired for shredding money by mistake. Lisa finds it difficult to adjust to the change.

Lady Baden-Baden decides to work at the Blue Spruce Cafe, much to Mr. Knox's dismay.

When Troy Malone comes to visit Melissa, Ralph tries to win back Melissa's affection by entering a flight contest.

The Sneer Theatre is about to be re-opened; just in time for Cedric, who has written a play (""The secret of the cursed treasure""). Lady Baden-Baden appears to the casting and gets crazy for the main role. In order to make sure she gets the role, Knoxie puts Cyril under pressure, who in turn tries to convince Cedric to modify the play in favour of Lady B.B. Cedric agrees to 'improve' the script, and from this moment, odd things start to happen - Cyril has a series of utterly improbable accidents each time he tries to take influence in Cedric's writing. When they hear the phantom's threatening voice and realise there's someone behind the events, Bert and the pigs unpack their ghostbusting equipment (they've got the will, they've got the technology!) After a chase and fright sequence, the phantom is revealed to be another author formerly employed and exploited by Cyril, who wanted to take revenge, while saving Cedric from suffering the same fate.

Cedric and Bert take sky diving lessons and Cyril falls in love with a film star.

Prof. Smedley-Smythe holds a science contest for young people, who are to prepare any kind of scientific projects and present them to a jury. Bert's digging for dinosaur fossils, while Cedric and his father build a flight device resembling a pedal-driven helicopter. After not too long, Bert finds a promising tar pit and prepares to examine it more closely. But the pigs, thinking they'd improve Cedric's chances in the contest by sabotaging Bert's project, sink a heap of fresh bones in the pit, and thus cause confusion as usual.

A real tear jerker. Bert and Cedric show Bentley their secret fishing hole, and are dismayed to see it feature in one of Cyril's advertising campaigns. Soon after, the pigs moonlight for Mr. Midas, and dump some barrels in the river upstream of the waterhole. The next day, it becomes apparent that the barrels conained poisonous chemicals, and the waterhole is dying.

Bert and Cedric have gone skate-crazy. Cyril and Mr. Knox are trying to settle in the skateboard market; they have both developed their own product line and each of them equips a team for a coming race in order to prove the quality of his boards. There seems to be no place in the forest for two skateboard brands - they agree that the looser has to retreat from this market. At the pigs' place... Lloyd and Pink are huge comic book fans and members of a ""Mudman"" fan club, and feel quite elitary, scorning Floyd, who can't afford these books. In order to gain their respect, he begins to steal them from Willow's, and suffers from his bad conscience. In the end, he's going to be discovered and punished. During the race, Cyril's and Knox's race teams behave rather unfairly, trying to throw their opponent out of the race, but don't care for Bert and Cedric, which enables them to win the race (using neither Cyril's boards nor Knox's).

Bert and Cedric go exploring on an island to find a fallen meteorite, but they don't tell anyone where they're going and get stranded. Soon everyone else is desperately scouring the forest, and consulting Lady Baden-Baden's astrology, to find them.

Cyril has a short stay in hospital and makes a new friend. Bert realises he's been lied to by an advertisment and tries to get a refund from the unscrupulous Mr. Midas.

Cyril wants to join a golf club after losing a client to Knox at another club. Lisa sees an old friend from the City, and is pressured into smoking to fit in. Cyril is surprised when he finds out the final task he needs to obtain membership.

Bert falls in love with Lisa, Bentley's older sister, when she comes to visit the Evergreen Forest. After much procrastination, he gets a date with her. Meanwhile, Cyril Sneer must choose to attend a camp reunion with Cedric or meet up with a famous billionaire.

Cyril launches a new sattelite channel while Bentley is looking after Broo. The pigs leap at the oppurtunity to send their mother a mother's day gift she'll never forget! When Broo's face appears on the monitors just before lift off, a race ensues to save him.

To get a contract signed, Cyril Sneer agrees to look after Mr. Knox's nephew. This results in Cedric becoming the nephew's new bullying target.

When a famous magician shows up in the Evergreen forest, Bert is bent on becoming his apprentice. Meanwhile, Cyril Sneer tries to sell Knox his new $750,000 secure vault.

After being bullied by his classmates, Bentley is set on revenge. It soon transpires that Schaeffer is a black belt in the martial arts, and is persuaded to teach Bert, Bentley and Cedric.

Bert makes more promises than he can keep. The pigs try their han at jam making and things get decidedly sticky when their Mom turns up.

Sneers new factory production line has teething troubles. Bentley breaks for the summer, and the pigs soon talk him into working for them. Bert is appalled. After Bentley's early sucess, the pigs feel threatened, and destroy Bentley's work. When he's fired, Bentley is despondant about losing the job. Then, Cyril finds out the truth.

Cyril Sneer's childhood friend Woodchuck Berry shows up in the Evergreen forest. When Woodchuck is hired to play at Schaeffer's cafe, Cyril is given another chance to play with his friend onstage.

The pigs, mightily discontented with their living and working conditions, get in contact with scandal reporter Ms. Barbara LaFrame: a TV talker specialized in interviewing and tormenting rich people who keep their personnel as their slaves... The pigs discredit their boss and she promises to pay him a surprise visit with a camera team that would ruin his reputation. But they soon regret this idea when they learn that her last victim, Milton Midas, utterly destroyed and ruined by her, had to fire all of his staff. Fearing for their jobs, they now try to get rid of her again, describing her boss as a wonderful, friendly father, rather than an employer. But she's not so easily convinced and tries to get her interview. Cyril flees from her, ending up on a roof, from where he crashes through a window and lands right in a ""bachelors auction"", where the reporter has to ""buy"" him for a large amount.

Bentley accidentally breaks Bert's new remote controlled car. Thinking he can find buried treasure is a cave system, he and the pigs end up trapped. Lisa and Bert must rescue them before the air runs out.
