U.S. Title: Thomas and Percy's Mountain Adventure
Air date: July 14th, 1992 (UK), April 21st, 1993 (US)
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.
Tropes featured in the episode:
- Christmas Episode: In the UK. In the US however, it's dubbed as a Thanksgiving Episode. This is because the Shining Time Station episode it aired on, "Billy's Party", was centered around Thanksgiving.
- Series Continuity Error: Percy doesn't know who Santa Claus is even though he saw him in the Christmas party in "Thomas and the Missing Christmas Tree".
- Snowed-In: Happens on Sodor, but mostly the mountain village.
- Stock Footage: Footage from "All at Sea" is used.
