Cyber Teacher Mr Johnson

The Cyber Teacher Mr Johnson was a robotic, superhuman duplicate of Lucy Wilson and Hobo Kostinen's schoolteacher at Ogmore-by-Sea, Mr Johnson. Whatever its true nature, the duplicate proved a much more enthusiastic and compelling maths lecturer than the real Mr Johnson, launching into a maths-themed rap which fascinated Lucy despite her confusion at the Cyber Teacher's presence.
