Thomas's Christmas Party - S1.E26

It's Christmas on the Island of Sodor, and after Edward reminds the engines of last Christmas when an ill Mrs Kyndley waved her dressing gown out of her window to save Thomas from a landslide, Thomas decides to thank Mrs Kyndley properly by having a Christmas party for her. The Fat Controller agrees. However, on the day of the party, Mrs Kyndley is trapped in her house by snowdrifts, so Thomas, Toby and Terence go to her rescue.
