The Flim Flam Brothers have gone too far. Applejack is outraged when they steal all the Apples from Ponyville's Orchard, as well as they sprayed the roots with a chemical that doesn't allow apples to grow. She says that the Flim Flam Brothers have to make a machine to make apples, no matter how. Applejack knew whatever tree they put in that land, nothing would grow.
The Flim Flam Brothers make a huge Machine that has a little ingredient to make the apples it makes even sweeter:
The Sweetness of Ponies. Pony Flesh.
