Carnival Cruise Lines is coming to Baltimore and what better way to kick off the celebration than with a cake of the cruise ship Carnival Pride from Charm City Cakes! To Duff's surprise, Katie asks to take the lead on this massive project. But she's quickly overwhelmed by all the details on the Pride and falls behind schedule - can Duff and the decorators save her from going down with the ship?? And OMG! Lauren is making a cake inspired by the totally awesome 80's. Duff, Mary Alice and the decorators get radical remembering all the tubular 80's fashion. The beat is on as Duff and Geoff create another crazy cake... A giant marimba!
