In "Farmer Remy", the tractor's movement was animated with CGI.
"Homeward Hound" acts as a sequel to "Animal Farm", which focuses on Phoenix and the animals.
In "Country Side", Tilly said she couldn't find Saxon, which leads into the plot of "Homeward Hound" where it was revealed she left Saxon at Gramma's prior to the move back to the country.
The music during the montage where Remy helps Tilly and Nancy is the same tune from "Wishing Well" where Cricket was doing good deeds to earn money for Tilly.
Moral for Farmer Remy: Remy learned it takes time and practice to learn something new. Bill also learned not to panic and assume the worst about Cricket's tractor driving.
