Horrid Lorry is the second episode of the fifth season.
One morning, Percy is late to collect his train from the docks. Cranky begins to criticise Percy, but Percy complains there is too much work. Cranky suggests it would be better if lorries did his work. Percy is shocked by this. Later at the sheds, Percy tells the other engines what Cranky had said. The other engines are dismissive, but Percy worries that lorries might actually come.
Soon, three lorries do arrive and Cranky is delighted. One of the lorries is rude towards Percy. Later, when Percy sees Thomas and James, he finds another lorry being rude to them. At the quarry, Toby runs across another lorry. Toby's driver tells him to ignore the lorry, and they proceed to the flour mill. But when they arrive at the flour mill, Toby is shocked to find yet another lorry. The lorry tells Toby that they are doing his jobs now. The foreman tells Toby's driver that he is sorry for Toby's replacement.
Toby's driver then tells him they can head to the farms. As Toby trundles toward the farms, he watches a lorry having trouble navigating on a treacherous road. The lorry then falls off a cliff and crashes into some rocks below. The smashed lorry is taken to the docks, where Percy begins to laugh at him. Butch arrives with the lorry from the flour mill.
The tow truck driver explains to Toby's driver that the lorry was overloaded with flour and broke down. James whistles excitedly as he watches men bringing the third lorry in on a barge. Another workman elaborates that the lorry reversed into the sea. Thomas arrives, laughing at the lorries and calling them "The Brothers Grimm": "Smashed", "Broken", and "Sunk". The lorries promise to return, but never do. The engines commit themselves to their work to insure the lorries never return.
