'Santa Claus-Trophobia' by Bob Block

It’s Christmas at Little Stockbrush: Robert and Aunt Millie have put up the Christmas tree and the robots have put up their stockings. Robert and his robots have also been tasked with organising a children’s party at the village hall, and while the robots get the decorations ready, Robert tests his new computerised electronic organ. Meanwhile, Marken gets into the festive spirit by dressing up as Santa and, together with a rather ‘humbug’-ish Plummer, takes Robert’s robot sleigh out for a test run – and then returns covered in oil after the thing crashes. When Marken tells the robots a (badly-translated) story about Father Christmas, Katie gets all emotional and decides to give him a present: the leg of robot George, which contains the papers Rober confiscated from Marken. Now free of Robert’s hold over them, the elated Marken and Plummer attempt to make a break for it; however, Katie realises his mistake and confesses to Robert and Eric. As the spies drive off on the motorised sleigh, Robert, Eric and Katie give chase...
