Thomas volunteers to take the Duchess to tea. Diesel tells Thomas that his work with Whiff will make him too stinky to take the Duchess. As Whiff and Thomas puff along, Thomas uncouples from the Garbage train and Thomas takes ‘sweeter smelling’ tracks. Whiff struggles with the heavy train and has to stop on the track, causing Thomas to crash into Whiff. Garbage flies into the air and all over Thomas! Thomas is the stinkiest engine on Sodor! While Thomas cleans up the garbage, he gives Whiff the special job of taking the Duchess. Sodor Surprise Day is a day in which people and engines surprise each other and make each other laugh. When Gordon declares Sodor Surprise Day to be silly, Thomas decides to show Gordon how much fun it can be, instead of doing his job. He surprises Gordon at the coal hopper, at a junction and then at the docks! But Thomas only succeeds in ruining the fireworks for the Surprise Day party and doesn’t do his job. Thomas then concentrates on doing his job and finds a fantastic alternative to the fireworks. No one is more surprised than Gordon!
