- "You had a real, live piggy-in-the-middle, Mavis!"
- ―Stephen Hatt and Bridget Hatt[src]
Piggy-in-the-middle! is a magazine story.
Mavis thinks that Bridget and Stephen are being unfair to their friend. They will not let him catch their ball. Bridget and Stephen explain that it is part of their game called "piggy-in-the-middle" and that their friend, Marcus, is the "piggy-in-the-middle" and has to try and catch the ball. Later, Mavis has to go to collect Farmer McColl's prize pig. The Fat Controller allows Stephen and Bridget to go with her in the brake van. When they get there, they see Farmer McColl chasing after his prize pig. The pig gets onto the railway line. Mavis, with the help of Neville, manages to trap the pig in between them. Farmer McColl puts a lead on the pig and Stephen and Bridget laugh as Mavis had a real "piggy-in-the-middle"!
- Farmer McColl looks different.
