Wren is a minor character of Bunnicula.
While possessed, Wren appeared to be very manipulative and greedy. She charmed Arthur into inviting her over to his home and hypnotized him into thinking that they would get married, despite them just meeting.
When not possessed, she showed a confused side to her surroundings and displayed no signs of greed unlike the puppet. After Arthur Monroe tried to flirt with and kiss her, she got very shy about the act and even said they needed to take baby steps, implying that she is not at all flirty like she is when controlled.
