Cody is upset because his Ken doll, which he treats as a boyfriend, has been accidentally blended into pieces by Joseph. The group tries to find a replacement Ken doll to console Cody, and they eventually manage to get one from Jonathan, who collects rare dolls, in exchange for a rare Britney Spears Barbie doll.
However, to obtain the Britney Spears Barbie doll, they have to trick Jonathan into giving it to them. They do this by pretending that Justin Bieber is coming to meet Jonathan's daughter, and they hire a beaver-costumed person to impersonate Justin Bieber.
