soon as he starts singing the song "security" the ocean beast attacks damaging Christopher as the girls rush to his aid to help him out and the ocean beast disappears into the pacific ocean. the team runs to them as Christopher's head starts to hurt really bad as Janice places an ice pack on his head and Jana asks if he's okay while using a term of endearment as he responds quietly with "I think so girls." as they then kiss his cheeks in joy of his survival and the monster then attacks causing the three to run outside and see the monster at first glance and run as the first chase scene song plays in the background.
