But James is worried he will be seen by his friends and tries to hide his pink coat from them on the way. Thomas has to wear a replacement funnel while his own is being fixed and he is embarrassed about it. When Thomas is asked to carry some special bubble liquid for Mr. Bubbles, the famous clown, 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 doing so, learns that making people laugh can be a good thing.
