Dinosaurs - Season 2 Episode 3 -

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.
