Molly MacDonald

Molly MacDonald  is a fourth grader and an old member of the Tough Customers. Despite her tough exterior, she has also shown her more creative side in episodes like The Agent of Change. Her younger brother is James, who is also D.W.'s friend and classmate. She enjoys listening to the heavy metal band Mütakrüde and taking care of James.

Personality and Skills
In earlier episodes, she can be sarcastic, selfish, and a bigger bully than Binky at times. Despite this, she still gives great advice which was revealed as her hidden talent in Brain's Chess Mess, and she helps her younger brother James. In Mind Your Manners, she gives some practical advice to the Tibble Twins, while showing courtesy to another customer. However, Molly has a complete change of heart in The Last Tough Customer after witnessing her brother James bullying Amanda Hulser, and resolves to stop being mean to others. Molly is very skilled in skateboarding, being shown to enjoy practicing at the skatepark and using it as her main means of transport outside school. She is also a talented artist, as seen in The Agent of Change when she joins up with Muffy and Francine to create an animated movie after being annoyed at there being no popular movies with female leads.

History
In the episode "The Last Tough Customer" it was revealed that she was bullied as a kindergartner. That event marked the day Molly became a bully. Before she got bullied, her hair was put up in a bun on top of her head, giving her the name "Muffin Head".

James MacDonald
James and Molly seem to be quite close, James has been shown to turn to his older sister for advice on many occasions, and look up to her. In "The Last Tough Customer" she stopped James from becoming a bully after witnessing him bully another child at a water fountain and promising to stop her mean ways.

Arthur Read
Arthur and Molly are shown to be friends in a few episodes, but usually they aren't by the end of the episodes and series. This public attitude, however, is just a cover for their secretly staying friends.

The Tough Customers
Molly seems to like the tough customers very much. In "The Last Tough Customer", she didn't want the Tough Customers to be nice. Also in "The Law of the Jungle Gym", she didn't want to give the Jungle Gym to Muffy for her photos. She is the most loyal Tough Customer and is possible tougher than Binky, Rattles, and Slink, who each has a secret, soft hobby.
