Who are the flat characters in animal farm?

In George Orwell's "Animal Farm," flat characters include the sheep and Mr. Jones. The sheep represent the easily manipulated masses, often bleating slogans without understanding their meaning, while Mr. Jones, the negligent farmer, symbolizes the oppressive human authority that the animals initially seek to overthrow. Both characters serve specific roles in the narrative without significant development or depth, reinforcing the themes of manipulation and power dynamics.
