Dinosaurs — Season 2

Baby, unappreciated by Earl, inexplicably grows a golden horn from his forehead. Earl is appalled, until he learns from the dinosaur druids that the appearance of a golden horned baby was foretold in The Book of Dinosaurs. Baby becomes a cult object and Earl is a celebrity by association. The horn eventually comes off, but Earl comes to appreciate the treasure that his baby is all by himself.

Fran demands her family spend more time together, and, in order to get their attention, she wrecks the TV. When a meteor crashes through the roof of their home breaking their other TV set, Earl leads the family to try their luck as game show participants, where the first prize is a new TV. Earl messes up on obscure areas of knowledge, but is humiliated when all of the questions focus on how well he knows his family, which is not as well as he thinks. They study their history, but by time they appear on the show, all of the categories have to do with the latest television events.

Robbie refuses to join a Young Carnivore Association and considers becoming a herbivore. Earl is appalled and hauls Robbie off to hunt in the wilderness, to reinforce the carnivore ethic: the bigger eats the smaller. When Robbie is eaten by an enormous swamp monster, Earl is forced to reconsider his philosophy. When Earl, too, is eaten, the father and son continue their argument inside the belly of the beast.

Charlene is despondent because she is the last girl in the eighth grade to grow a tail. Her outlook miraculously changes when her tail appears overnight, however. Earl's awareness of his little girl's budding womanhood drives him to distraction, but reassurance from Charlene that she will always be her father's little girl cheers him up.

It is Earl and Fran's 20th wedding anniversary, the Graptolite anniversary. Graptolites are the sweetest-tasting and most adorable little animals, but they are also quickly disappearing from the earth. Earl has acquired the last pair before they become extinct, and everyone else wants them, particularly his boss Mr. Richfield. Robbie befriends the creatures and finds they are the very last pair. Soon, father and son are at each other's throats over the fate of the Graptolites.

Richfield institutes an Employee Suggestion Box, which has Earl and Roy racking their brains in an effort to impress the boss. At Earl's suggestion, the employee coming up with the best suggestion each month will receive dinner with Richfield and their name on a plaque - with Earl named the first "Employee of the Month". Earl's big moment is somewhat tarnished, though, when Richfield does not show up for dinner.

Charlene is left alone to babysit Baby Sinclair, who is teething, while Fran and Earl go out for a nice romantic dinner. Fran gives into temptation to call home, but no one answers; the children have been kidnapped by food that has been left in the refrigerator for too long and gone bad. Charlene must use her wits to foil the food before Fran and Earl get home.

Robbie is assigned Tree Pusher as his life's vocation by the all-powerful The Job Wizard. In the process of showing an unenthusiastic Robbie how wonderful a job Tree Pusher is, Earl comes to realize instead how pointless his own life actually is, and retires to bed, unable to move. When Robbie has to replace Earl at the worksite, he gets into trouble and Earl must rally to rescue his son.

Earl and Fran's marriage license expires. When Earl bungles the renewal test by displaying complete ignorance of the details of his marriage, Fran considers not picking up Earl's option. Earl is forced to move in with Roy, while the Sinclair's new next door neighbor, Monica – an Apatosaurus and the first divorced female in history – shows Fran that the single life has possibilities.

Robbie hires his best friend Spike to teach him how to pick up a girl that he has a brutal crush on, but Spike's unique advice gets Robbie grounded; a situation that Robbie finds not nearly as unbearable as the discovery that Spike, having refined his flirtatious technique, is dating the girl of Robbie's dreams.

Planning for Baby's first birthday, the Sinclairs discover evidence that their baby may have been switched with another baby while still an egg. Earl is tantalized by the notion that there is a polite, well-behaved baby out there somewhere who might be his son. Fran is unwilling even to consider the possibility until she meets the other baby – who looks exactly like the Sinclair baby except he is green like Earl – and the other father shares certain personality traits with the Sinclair's baby.

The happiest holiday in Pangaea is approaching, and Earl overspends on presents for the family. When the traditional WESAYSO bonus fails to come through for Earl, the family is placed under financial threat. Any hope for a joyous holiday is dashed when their refrigerator is repossessed. With no food, no refrigerator, and no money, the family is forced to fall back on the spiritual side of the holiday.

Monica begins working for Mr. Richfield where she first meets her supervisor Al "Sexual" Harris. Al "Sexual" Harris uses suggestive language, but Monica turns him down. Al "Sexual" Harris fires Monica, who in turn takes the company to court with charges of sexual harassment. This forces the courts to try to determine what exactly "Sexual Harris meant".

Fran calls a phone-in TV advice show with a suggestion for the host and ends up hosting the show herself. Fran's anecdotes over the air expose Earl to ridicule at work, however, and pressure builds for her to quit her job.

As a science project for school, Robbie comes up with an idea for tapping the geothermal energy of volcanoes to heat the homes of all Pangaea. The idea is taken seriously by the government and Robbie seems to be a hero, except that his plan for free energy threatens the business interests of the WESAYSO Corporation, which sells energy for a profit. When WESAYSO puts the screws to Earl to squash his son's idea, Earl is put in conflict with Robbie. A DNN news report segment shows a volcano eruption at the summit of Mt. Thunder at the beginning of this episode; stranding dinosaurs in their homes, ravaging acres of farmland and forcing schools and workplaces to be closed due to an "Ash Day". At the end of this episode, it is revealed in the DNN news segment as it is being mentioned that WESAYSO has acquired the volcano, that the mountain (when seen on the Sinclair's television set and the cameraman - on the Sinclair's TV screen, of course - shoots the footage of the mountain from its ground level next to a "Keep Out" sign) bears a resemblance to the same volcano seen on the opening (and mid-bumpers with a pterosaur in flight) credits (either from a ptero-copter or the top of another mountain paralleling the volcano) to all of the episodes of Dinosaurs with the show's name and logo (and even the episode titles followed by one credit on the VHS releases) revealed in capital at the bottom (or middle) of the volcano on the television screen. While it is a possibility that the volcano seen in the show's opening credits and mid-bumpers (or another volcano, presumingly Mt. Thunder from this episode, made to look like the one from the opening credits) is believed to be Mt. Thunder, it is not officially revealed or confirmed by Dinosaurs ' producers.

Sir David Tushingham, a self-important archaeologist, attempts to shed light upon the mysterious world of the dinosaurs in a mock-documentary featuring clips from the first eleven episodes that proves the theories of modern science fall far short of the real world in which Earl and his family inhabited millions of years ago.

Following a fierce argument with Earl, Robbie storms out of the house to meet Spike and discovers an appealing leaf that, when ingested, makes them both effusively happy. Upon returning home, Earl is surprised to find Robbie in such an elated state until he samples some of Robbie's leaves. Expecting to find father and son at war, Fran is puzzled when she discovers Earl and Robbie arm in arm. Suspicious of the tantalizing leaves, Fran exhibits cautious restraint and becomes increasingly concerned when her family happily decides to remain at home rather than go to work or school. Earl's lack of concern after discovering he has been fired forces Fran, who refuses to become co-dependent, to abscond from the house and leave a delirious Earl, Robbie and Charlene to hopelessly fend for themselves. Having run out of leaves, they are forced to recognize what they have become, but Spike tests their resolve when he uncovers fresh leaves. This leaves them with a choice of two things: their lives, or the plant. At the end of the show, Robbie gives a PSA announcement why drugs are bad and what happens to people when they take it.

When Ethyl unexpectedly dies, she goes to the afterlife and finds out how beautiful it is. Before she can be reunited with her husband, however, it is revealed that she is only unconscious and will wake up. Anxious to soon return to the afterlife, Ethyl goes on TV and tells the viewers how wonderful it is. Unfortunately for Ethyl, the afterlife has its own message for her.

A petty territorial dispute between the main dinosaurs and the four-leggers across the swamp escalates into the first war ever to exist. Robbie is selected to go into the 'Nuts To War' war. However, Fran is worried and scared to death that Robbie will be killed in the war, so she decides to let Earl and Roy go to the battlefield.

Earl and Roy join Charlene as USO entertainers, and rush to the front to retrieve Robbie, because it looks like this "war thing" is getting a little bit out of hand. Earl tries to stop Robbie from going through with the war, but Robbie ignores his father's wishes.

When the Chief Elder dies in the process of naming Baby Sinclair (now "Aaah Aagh I'm Dying You Idiot Sinclair"), Earl becomes embroiled in an intense but unsurprisingly non-substantive campaign with B.P. Richfield for Chief Elder of Pangaea: first as Richfield's patsy, and later as a self-made, come-from-behind candidate bent on preventing a bleak homeland under what appears to be Richfield's imminent rule.

Feeling like a social outcast at school, Charlene begs her father for money to buy an expensive fur coat that none of the other girls have, and her grandmother ends up giving it to her. The coat indeed makes Charlene the envy of her friends, but unlike other status symbols, it talks, and begins to make demands that cause Charlene to become alienated from her family and friends, especially her best friend.

Robbie is drafted as the leader of Spike's gang when the former leader disappears after a wild night with Robbie and the gang assumes that Robbie ate him.

To improve its public image, the WESAYSO Corporation picks the perfect employee family to be featured in their company advertisement. Earl's dream comes true when his family is chosen, but WESAYSO feels Roy has more audience appeal. When the ad campaign is a hit, Earl moves out of his own house so Roy can move in. Roy soon learns that parental responsibility is more difficult than he thinks, however, and Earl realizes that his family and friend might not be successful without him.
