Henry and the Elephant is the nineteenth episode ever made in Season 4.
The big engines are happy to help when a circus comes to Sodor, but after the circus leaves, Henry is asked to investigate a blockage in a tunnel. The "blockage" is revealed to be an elephant that escaped from the circus. The workmen give him cake and water and, when Henry unluckily lets off steam, the frightened elephant sprays water onto Henry. Gordon and James feel sorry for Henry, but tease him anyway. Thomas tells Henry that he handled the situation rather well.
- At the beginning of the story, Thomas has Edward's whistle sound.
