Snow white works but not on a farm like Applejack, but both Applejack and Snow White work. Snow White works by fixing up the house, and Applejack works on a farm so this is a good match

For her love of animals.

The animals thing duh

Cinderella loves animals and so does Snow White, but Snow white does work just like Cinderella and Applejack, but she is like both: Fluttershy and Applejack so both

Both are cheerful.
