The inspiration for A Shark in the Tub was Sonya's daughter, Tara, who was terrified of getting into the bathtub after seeing the movie, "Jaws." She was in late grade school at the time. Tara's sister, Trish, and brother, Tyler, tormented her by humming the "Jaws" movie theme song For about a week, Tara would not put her feet in the tub and insisted on straddling the tub sides when showering. She had frightening thoughts of sharks being in the water.
