Episode Title:The Spotless Record.Episode Description:Thomas plays a trick on a new engine called Arthur, who has never been naughty or in an accident, by telling him to keep the troublesome trucks in order while taking some vans of fruit to market. But when Arthur gets fed up with the troublesome trucks' singing and orders them to stop, they get him into an accident and ruin his spotless record. When Arthur explains his accident to the Fat Controller, a guilty Thomas fesses up to causing it and the Fat Controller orders him to help clean up the mess. At the wash-down later, when Arthur is being cleaned, Thomas apologises for tricking him. Arthur forgives Thomas and they both agree that all spotless records are made to be broken and then mended again, just like friendships.
