Thomas and Percy's Christmas Adventure

Thomas and Percy's Christmas Adventure, retitled Thomas and Percy's Mountain Adventure in American releases, is the twenty-sixth episode of the third season. In the US, it first aired on the Shining Time Station episode Billy's Party in 1993.

Plot
Thomas is looking forward to delivering mail to the people of the mountain village, but when Sodor is struck by a snowstorm, the mountain village is snowed under. Thomas is summoned to help and Percy takes the mail for him.

On the way there, however, a fogman stops him and sends him to get help. Percy tells Harold as Thomas arrives with Terence and asks Percy to tag along to help with the rescue. Harold drops hot drinks and food for the villagers and Terence clears the streets.

As a token of gratitude for their hard work, the villagers make a surprise. When the engines wake up, they see the shed decorated with new paint and Christmas decorations and agree it is the best Christmas ever.

Errors

 * Some of the parcels Harold drops hit the people.
 * For the American audience, the celebrated holiday in the episode was Thanksgiving, which was unrealistic because Sodor is part of the British Isles.
 * Percy doesn't know who Santa Claus was, even though he saw him at the Christmas party in Thomas and the Missing Christmas Tree.
 * Since some US releases use the UK footage but still have the US narration, the narration is out of sync with the picture and music towards the end. This mistake is cleared up in the restored version.
 * A deleted scene in the sheds shows that the tracks end in front of the engines.
 * There are more berths than the usual six in Tidmouth Sheds.
 * Even though the celebrated holiday in the US version is said to be Thanksgiving, all of the Christmas decorations are left in place.
 * A brakevan should have been added to Percy's train.
 * When Percy leaves his mail trucks and goes to find Harold, he some how turns around.
 * Through most of the episode one of Percy's lamp irons is missing.
 * In the close-up of the fogman, the studio is reflected in his lamp.
