Darla Dimple is the main antagonist of the animated movie Cats Don't Dance. Darla Dimple makes an effort to appear sweet and kind when in public, but she is a spoiled, mean and ultimately psychotic villainess who has no qualms about exacting unjust vengeance on anyone she feels has wronged her. Darla is also a menace to her staff and underlings - to the point they try everything to keep her happy, due probably to her being their main star plus the fact nobody wants to risk invoking her wrath and having the dreaded Max to deal with as Darla has a very bad temper.

Danny discovered Darla's dark side the hard way when he accidentally offended her by overstepping his place and attempting to sing - Darla was infuriated by this and went into a temper tantrum that climaxed in her calling in Max, who proceeded to grab Danny and intimidate him. However Danny wouldn't give up his dreams and this inevitably put him into conflict with Darla again. Darla planned a scheme for the animals to get kicked out, singing 'Big and Loud' to Danny, making him think that she is doing something for him. During the animal's performance, Darla began to sabotage the stage and succeeded her goals. When the animals get kicked out, she came up to Danny in her private car, hugging him while thanking him for his participation, revealing to the animals his responsibility in this scheme and Darla chucked out Pudge out of her car and drove off, laughing her head off as she goes.

At the end of the movie Darla's own temper got the better of her when she exposed herself as the spoiled monster she truly was to the entire audience when, after a failed attempted at sabotage, she yelled at Danny that she should have drowned him when she flooded the stage, unaware a microphone was currently attached to her due to her falling from a catwalk and becoming entangled in wires and stage-props. Darla was promptly dropped through a trapdoor by Pudge (who pulled a lever which opened the door), it is not known how she escaped injury, but at the end of of the movie, she has been fired from show business, and is clearly seen working as a janitor during the end credits.
