They discover a toy store in Marshport with only one but worry the store owner will not sell it to them because of the family's history at that store. When Harley's siblings refuse to try out her latest invention called the Grocer-Whee, she turns to Ellie to give it a test run, but Ellie worries she will get hurt. Five of the Diaz kids are held in the restricted area. To make things worse, Georgie's game goes into overtime. Guest stars: Davida Williams as Kelly, Tessa Harnetiaux as Natalie, P.L. Harley strikes a deal with Buddy, having him compete with her family in the race, and if they win, he will fix the bus for free. Guest stars: Audrey Moore as Coach Heller, Coryn Mabalot as Jo, Lance Lim as Kevin Casey. Meanwhile, Rachel tells Suzy and Tom about her internship, but they are not convinced she is ready to go so soon and recall a large list of promises she failed to deliver on. They are ready to bust Daphne as she sells her toys and other things to the neighbors, but when Harley finds out why, she realizes how much she has been neglecting her sister lately. Though Harley promises Rachel she will fix the problem in time for a pep rally, she fears the controller will malfunction again and ends up bailing. In showing Rachel how much he loves her, Cuff ends up getting fired by Tom for defacing store merchandise. As the children start on the garage, Tom shares messages from an old answering machine, dating back to Harley's birth. Meanwhile, Georgie is selected to lead the parade by Mrs. Sullivan, who also helps get her in shape to walk the route, while Rachel and Daphne compete for Marshport queen. As she and Suzy spend time together as friends, the Diaz children notice radical changes, such as healthy food, limited television time and no dangerous objects, none of which suits them. One of those ideas ends up distorting the Diaz family's satellite dish, and since Tom was watching television, she gets caught and grounded. Harley sees it as an opportunity for Aidan to change his selfish ways by interacting with her family, but when they try to engage him in helping with the party preparation, it turns into a mess. To find out more about Aidan, she orchestrates a fake game show, with Ethan as host, and sees a common thread to Aidan's answers—his father, Charles Peters. I'm literally the only one in this family who consistently looks hot. Meanwhile, Ethan is trying to get new subscribers for his web channel by filming a new segment starring Lewie and Beast at Tom's store, but when they see the segment is a failure and are no longer allowed to film in the store, they go to the bake sale and end up capturing Suzy and Bethany's arguing on camera. Harley sees that as an opportunity for the two to get away for the weekend and suggests Rachel be in charge. Under Abuela's watch for the weekend, the Diaz kids are committed to making her visit disaster-free, that is, until Harley learns that Ethan spilled her deepest secret. When Rachel comes into the store to be with her boyfriend, he decides his job is more important, and it devastates Rachel. Disappointed, they all go back to their rooms. She decides to rent the family couch to a stranger, picking up the idea from the Peters, who are renting a room in their house. Harley struggles to find the right gift for Aidan after he gives her one that turns out to be something she needed. When Suzy and Tom find out, they promise the twins separate parties for their ninth birthdays in a few months. With Daphne, Lewie, and Beast's help, the two girls concoct a plan to convince Ms. Peters to change her mind, but she sees through their act. When they were around Mr. Delorco, each of them assumed the other's identity, which ended up carrying over into their pictures because the teacher was present for those. It’s quince day! Meanwhile, Rachel uses Harley's help to make her friends jealous. You're lucky we're family, or I'd hurt you! Ultimately, the competitions fail to produce a winner, but the children agree to make the attic space a family game room. Her mother is unable to drive her there, so she looks to Rachel, who has her learner's permit, and asks her to take the driving test to get her license. Ellie is shooting a video about Harley as an inventor, but in doing so, Harley notices her struggle with keeping the camera focused on her. Harley and Ethan soon discover that Suzy's lack of friends—including not staying in touch with her old ones—is causing her to cling a lot to the family, so the two use an online site to connect their mother with a new friend who also lives in Marshport. After Tom tells Harley he and Suzy will double whatever money the family earns, she scraps Ethan's plan and wants everyone to make as much money as possible, so they can reach their goal to buy an above-ground swimming pool. Harley tries to save Ellie from boarding school. Mischa reminds them that they are under contract, but when Harley shows footage of the crew's plans, using the camera feature of her vacuum cleaner invention she first showcased on Girl Power, the crew calls off the reality series. After Georgie informs Lewie and Beast about what is really going on, the twins get Harley and Aidan together, but it is short-lived. Meanwhile, Lewie and Beast decide to camp in the backyard, and Suzy and Tom are not delighted about it. Suzy tells Harley to simply agree with Aidan, as that is what she does to avoid arguments with Bethany. Meanwhile, Rachel joins Ethan's film club at Tom's bait shop, but Suzy and Tom do some investigating after seeing what actually goes on there. Avid inventor Harley is all set to accept a community award, but must first devise a way to get her family out of the house and to the ceremony on time. They don't even have a table big enough for all the seven kids and their parents, Suzy and Tom Diaz. She uses her Mom Tracker device to track where her mom is hiding in order to drink her coffee in peace. Suzy and Tom call a family meeting and find out that Harley eavesdropped on their conversation in the attic, leading them to drop their plans. She also clears the myth about the "curse", which was about more than just the fighting among her grandchildren. This is mentioned throughout the series. Harley hires Phil Durning to assist with her slushy business at the bait shop. Harley eventually patches things up between the two. She develops a robot intended to help with her teacher's mundane tasks and allows Lewie and Beast to help her program it.
