S03E01 - The Knights of Busytown
Synopsis
Mr. Fixit is delighted with his new invention––a machine that will take him to the center of the Earth, and it's all ready for a solo trip. Except the solo trip ends up being not so solo when Huckle, Lowly, and Mr. Frumble end up tunneling under Busytown. Up on the surface, Busytown is dealing with some serious traffic but now, thanks to the Mole Machine, Busytown's all set for its first ever subway. / The monks in Abbot Thomas' monastery are very happy, except for Brothers Denis and Pierre: they're responsible for the cleaning and doing the dishes. When the King of France arrives for a tour, all the monks do their best to make him happy. And luckily for Abbot Thomas, Brother Denis and Pierre are there to invent tennis so everyone can have lots of fun. / Mr. Gronkle is fed up with his ancestral castle which is falling down, so he decides to tear it down and build a modern shopping center in its place. The cat family finds out and they start a petition to save the castle, but it's Gronkle's own nephew who saves the day when he reminds his uncle about how a much fun the young Mr. Gronkle had picnicking around the ruins with his own parents.
