Abi is hanging out at the café after another one of her shop-me-happy binges, but she's not happy when she catches café customer Nancy trying on her new shoes without permission. Nancy takes her revenge on Abi. She's a sea ghost from Victorian London and she thinks it's time to have a little fun outside the coral, so she traps Abi in her shell mirror and takes over Abi's body herself. Frantic Abi can't get anyone in the cafe to hear her cries for help, and she's annoyed that nobody notices that something's wrong. Can't they see that the real Abi would never do manual labour? While Abi's day just gets worse, Megan's trying to have a relaxing day off but she finds it really hard to keep away from her precious café. What happens if Robbo and Tai start serving sloppy salad? Desperate to check up on them, Megan starts to spy on the café, and wonders why Abi seems to spend so much time talking to the mirror.
