Harley makes a three-wheel pedal car "Harley Car" for her BFTF, Ethan. Ethan had invested in the Harley Car so that he can give kids free tours around Marshport, teaching them Hollywood history. He plans to call his business "Star Tours." He happily starts by driving Harley around.
Later at the store, Harley notices that the Slushinator is malfunctioning. She asks her dad for money to repair it but he refuses, saying that she should use the money she makes from selling slushies. But she's already used it all. So, she asks Ethan to let her use the car in the mornings to give kids rides in order to make money for the Slushinator. Ethan agrees. Harley starts calling her business "Harley Care."
When a woman comes brings her daughter for Harley Care in the afternoon during Ethan's Star Tour hours, Harley realizes that all the woman needs is a babysitter. Realizing the demand for babysitting and Harley Care, Harley secretly takes over Ethan's Star Tour hours by booking kids to her business and lying to Ethan that they're there for his Star Tours. Through this secret takeover, Ethan is surprised to be getting so many bookings while Harley is making all the money. She decides not to fix the Slushinator.
Harley is busted when Ethan overhears her telling a customer about a Harley Care babysitting session and asking her to call it "Star Tours" for a discount. Ethan confronts Harley for turning his tours into a mobile daycare. All he wanted was to have fun, not make money. Harley tries to convince her to join Harley Care so that together they can suck all the child care dollars out of this town. Ethan calls her out for being a babysitting supervillain.
After going on one ride with two problematic babysitting charges, Harley realizes how difficult it was for Ethan. She apologizes to him and closes down Harley Care. She finally gets a wake up call and fixes the Slushinator. Ethan gives Harley a Star Tour.
