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 in "Don't Ask Muffy" and even described 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 blockbuster movies with female leads, and also after Binky makes fun of them for wanting a female lead, explaining that a female lead is just boring.
Molly is a tall, slimmer anthropomorphic rabbit with long ears and a white complexion. She wears a sleeveless denim jacket with ripped jeans and red sneakers. Her hair is always let down and blinds her eyes, though they have been seen at least once.
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 tied up in a bun on top of her head, giving her the name "Muffin Head". Then when a kid asked if she was doing ok she gets mad and tells him to get lost. Then finally she rips out her scrunchie until her hair becomes like her everyday hair.
James and Molly are very 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 Amanda at the water fountain and promising to stop her mean ways.
Arthur and Molly are shown to be friends in a few episodes, but usually they aren't by the ends of the episodes. This public attitude, however, is just a cover for their secretly staying friends.
The Tough Customers
Molly likes 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’s the most loyal Tough Customer and is tougher than Binky, Rattles and Slink, who each have a secret hobby.
