This was the first Christmas Special not to be longer than half an hour, or about Christmas.
Basically it's just a regular episode, but shown at Christmas, and called a Christmas Special.
This would be a trend for many Christmas episodes from this point to towards the end - Stop That Castle, Potts in Pole Position, I Was a Hitman for Primrose Dairies are just a few I can think of that could pass for regular episodes. Same with Welcome to Earth possibly, yet somehow that episode did have something a little special to it anyway.
This special, which ties in with Series 13, marked the end of another era in the show's history. By the next series, there would be greater reliance on supporting characters, notably with the re-introduction of Aunty Wainwright.
