- "If he puffs himself up any more, his boiler will burst!"
- ―Percy, referring to Spencer[src]
Spotty Spencer is a magazine story.
Spencer is on Sodor. He has to take the Duke and Duchess of Boxford to open a new shopping centre. The walls of the shopping centre are made out of shiny mirror and are like a big mirror. Meanwhile, Percy is at Maron as the station is being repainted. When Spencer speeds through, he blows a pot of paint onto the rails. When Percy meets him at the shopping centre, Spencer sees his reflection and realises he has spots of green paint all over his paintwork.
