The series finale (you should view the unaired episodes before this one): Every May 14th the Bunch Beetles are supposed to return to Pangea and to eat the rapidly growing cider poppies; but only one Beetle remains as the WeSaySo wax fruit factory has killed them all. B.P. enlists Earl's assistance as the company attempts to fix the poppy problem by bombing the entire continent with defoliant which kills all plant life. Richfield next decides making it rain will bring the plants back, and to make it rain they need clouds, and they decide to make clouds by dropping bombs in volcanoes; but snow falls instead and the newscaster predicts the clouds will block out the sun for tens of thousands of years. Earl apologizes to his family for taking nature for granted over technology and bringing about the end of the world as they ponder what will become of them.
