The five costumes that Cat designs in the episode are Little Bo Peep, Superhero Cat, Sikowitz, International Spy Cat, and Tori's stunt-double dress for Beck.
This episode stirred some controversy as there is a scene where Beck is dressed in drag though he was not dressed in drag as he was simply wearing a dress because he was pretending to be Tori.
Rex calls Jade the Wicked Witch. This could be a reference to the episode April Fools Blank later in the series where Jade is the Wicked Witch of the West in the Wizard of Oz scene.
