Duck and Percy are struggling to cope with their work at Brendam, so another engine is sent to help. Unfortunately for them, Diesel is the only engine available and when the two see him, they refuse to work. The Fat Controller sends them back to work, but Diesel becomes unbearable after spilling some cargo and talking to others into not snitching. At last, Diesel carelessly pushes several trucks of china clay into the sea and is sent away for good. Duck and Percy are more than happy to put up with the extra work again, knowing they would rather put up with that than Diesel.
