Slippy Sodor is a Hong Kong DVD featuring five episodes from the thirteenth series.
Thomas has to wear a replacement funnel while his own is being fixed. He is embarrassed about it. Then Thomas is asked to carry some special bubble liquid for famous clown Mr. Bubbles. But when the other engines laugh at Thomas' funnel, Thomas rushes by them really fast to get away, spilling all the bubble liquid. Thomas returns to get more, and, in so doing, learns that, actually, making people laugh can be a good thing.
