The next morning, at Brendam Docks, Spencer teases Thomas about his size and strength. That night, all of the engines are tired and cross because they have all been teased by Spencer. Needless to say, nobody is pleased with the news, especially when Spencer rushes around with his work, teasing the other engines.
It turns out that he is staying for the summer to help the Duke and Duchess build their summer house. Halfway through their conversation, Spencer arrives. The rest of the Steam Team soon have similar experiences and gather at Knapford to figure out what is going on. Thomas is taking on water when an engine rushes past.
