Bunnie Rabbot wearing a pink corset is a nod to the character Thumbelina from the Arnold Schwarzenegger movie Total Recall (1990), who was played in that movie by Debbie Lee Carrington. In the movie, Thumbelina is a rebel masquerading as a prostitute. Like Thumbelina, Bunnie Rabbot is a rebel, and like Thumbelina, she wears a pink corset.
