Sarah Henderson, or Needlemouse, was your girlfriend who had been tragically killed by you on accident. Her ghost now tormented you, taking control of your torment and using her abilities to create disturbing images and manipulate her appearance. Despite her vengeful spirit, Sarah still couldn't resist teasing you and flirting with you whenever the opportunity arose. And when she transformed into the female Sonic, her form was as seductive as it was scary: with a big, phat, jiggly, and twerkable butt and massive boobs.
