Everyone is happy at Christmastime except for Duncan, the Scottish narrow gauge engine, who seems to be grumbling even more than usual. Victor offers Duncan a new coat of paint if he can refrain from grumbling for one whole day. Duncan rises to the challenge, but it is not so easy for an engine who likes to grumble to give up a lifetime habit.
