A cross-over between Hannah Montana (HM) and Suite Life of Zack and Cody On Deck (SLOD), would be pretty cool as a throwback/reunion type of episode, similar to what Disney Plus did with the Doctor Who series. The title would be "Rock star rocked the boat!". Miley got a last-minute invitation to perform on the Cruise the twins were on thanks to her Dad working his old connections from his rock star days and the main star guest called in sick. The original star guest was a famous female metal singer that Cody was looking forward to meeting, whose show he was dying to attend. Cody could not stop talking about, let's call her Hailey Mornings, and Zack was sick of hearing his twin brother talking about his celebrity crush. A scene showed Cody gushing gleefully about Hailey coming to the boat to other cast members, his brother teasing him for it, and London boasting about meeting Hailey multiple times at past Hollywood events. Mr. Moseby overheard this conversation, and having been told about the last-minute change of star guest, sarcastically told poor Cody that he was in for a disappointment since someone else was coming in place of Hailey. This shocked Cody and he started protesting non-stop, even overtly hinting that Mr. Moseby had the power and thus the responsibility to undo the change. Mr. Moseby laughed at his naivety and continued on his way. Later, Cody was shown talking to the other cast members about how much he had just learned about Hannah Montana's personal life, how many scandals she was in allegedly, and how her music was too mainstream for his taste. Little did he know, Miley had decided to arrive on the boat early with her friends and family, was sitting nearby, overheard his rants, got upset, and decided to confront him as Miley rather than Hannah. This resulted in a hilarious outburst of arguments about who was better as a singer and whose music was more popular. Cody talked a lot of smack about Hannah. They both walked away upsetbut Miley vowed to put Cody in his place. Later, Zack went to snoop on Hannah's staff crew to see if he could meet any other celebrity. Miley, already in costume as Hannah, found him snooping and confronted him, albeit confused at first due to her not realizing that Cody and Zack were twins and that it was Zack that she caught. After learning that it was Zack's twin Cody that she argued with earlier, Hannah decided to give Cody a little payback by playfully seducing Zack and asking him to come see her show. Zack, oblivious to Miley's ploy and mistaking her playfulness as her interest in him, dragged Cody and his friends to the show despite Cody's protest. At the show, Miley personally came out to greet the group and gave everyone but Cody VIP backstage and front-row passes which confused and upset Cody greatly. "That's not fair!" he shouted, "you can't do this to me!" Zack snuck out halfway through the show, found his brother still sulking outside, and decided to sneak him into the show to show him how great Hannah was. Cody came in after a weak protest to save his pride and was pleasantly surprised by how much he enjoyed the show. At one point during the performance, Miley saw cody star-struck next to his brother Zack and winked at him. Later on, having realized how childish she was, Miley talked to Cody, revealed her secret, and surprised him by facetiming Hailey who said hi to a mouth-gaping Cody.
