An enormous pillow fight has broken out in the sewer between Rattus and his siblings. With that in mind, he brings us a special battle-themed show chock-full of fight-filled history, including the English Armada, William the Conqueror getting schooled by a rival?s mum, invading Romans and scary Spartans, state-of-the-art weapons and warring pigeons. Loo Man proves to be an unwelcome visitor in a submarine, and loving mum Lady Harley writes a letter to her son while her home is under siege during the English Civil War!
