Thomas Comes to Breakfast/BoCo the Diseasel is the twelfth Ladybird book, based on the second series episodes Thomas Comes to Breakfast and The Diseasel. It is illustrated using photographs from the television series.
Thomas thinks he can manage without his driver, and he gets his chance when a careless cleaner fiddled with his controls. He rolls into the stationmaster's house as he is about to sit down to breakfast... Later, Sir Topham Hatt tells Thomas that while he is being mended a diesel railcar named Daisy will do his work. Meanwhile, poor BoCo is terrorised by the tank engine twins Bill and Ben when they suspect BoCo, "the Diseasel" has stolen their trucks.
