The workers at the park would purposefully play with her appetite, only feed her during showtimes for the pleasure of the guests. Because of this, the Mosasaurus has a hunger that cannot be satisfied. Whenever prey comes near her pod, she will eat anything. When the island was abandoned, her hunger got worse to the point where she would eat anything that moved.
