List of Dinosaurs Episodes - Season 4: 1994

Baby Sinclair complains of a monster under his bed, but the family doesn't believe him. One night while Fran and Earl are out, Charlene humors the baby by investigating his claim and is dragged into the monster's hole. Robbie and the Baby try to rescue Charlene, but they, too, are kidnapped. Just as they are about to be eaten, Robbie learns that the monster named Decker is angry at having his home (hole) built upon by the Sinclair's house. The whole crisis is resolved after the Baby suggests moving the house and the Sinclairs oblige.

Earl's accidental exposure to toxic waste transforms him into "Captain Impressive", a mysterious super hero committed to fighting crime and righting wrongs. Earl also sees his chance to outshine Captain Action Figure, Baby's current hero, by using his newly acquired superpowers against the forces of evil – until B.P. Richfield discovers Earl's hidden talents. Determined to use "Captain Impressive" for WESAYSO's benefit, Richfield quickly changes Earl from Super Hero to Super Huckster. Faster than you can say "shoddy merchandise", Earl decides to hang up his tights and retire from his career as a crime fighter.

The Council of Elders is convened to determine answers to the Great Question Of Life, and the answer is found to be Potatoism. Soon it's stake-and-potatoes for Robbie and Earl, when Robbie rejects the elders' wisdom and the duo is sentenced to be burned as infidels. But a gust of wind extinguishes the fire, and with it dies the people's belief in the message of The Great Potato.

Fran forces Earl to drive Ethyl to her 60th year high-school reunion. During the drive, their normal fighting and bickering ensue. Once at the reunion, Ethyl discovers that she is the only person from her class still living. Earl senses Ethyl's hurt and softens toward her. The family is in shock once Earl and Ethyl return being polite to one another. Meanwhile, with Earl gone, Fran tries to gather the rest of the family for a family portrait, and they end up at each others' throats.

When Earl is injured on the job and asks for a few days off, B.P. Richfield refuses and fires him instead. Robbie and Fran trick Earl into suing the WESAYSO Corporation for his $800 medical expenses. After a brief trial, Earl is ecstatic at the jury's award of $800 million. Earl begins to spend lavishly and behaves badly. Stung by the judgment and blaming Earl, Richfield announces massive layoffs and raises consumer prices. Earl doesn't see it that way and is happy with his new life, but finally he is forced to give back the money in order to return things to normal when Mr. Richfield sues him back for allegedly injuring his neck in a car accident.

Including a first appearance of Blarney but he will be back on Into the Woods.

Baby Sinclair enters the "terrible twos" and his behavior becomes horrendous, even defying belief as it reaches the standards of Linda Blair in The Exorcist. Desperate times require desperate measures, and the Sinclairs enlist the aid of "The Babysitter" to exorcise Baby's demons. When neither the exorcist nor doctors can cure the baby, Robbie hatches a plan for the family to fool Baby into believing he's three.

Every May 14, the Bunch Beetles are supposed to return to Pangaea to eat the rapidly-growing Cider Poppies. Unfortunately, only one Bunch Beetle named Stan remains as WESAYSO's Wax Fruit Factory has killed off the rest. B.P. Richfield enlists Earl to help rid Pangaea of the Cider Poppies which leads to a chain of events that would doom the dinosaurs.
