he orders it closed until the police have finished searching. Ann Cuthbert, the museum director, protests and mentions an important upcoming exhibition. Margo discovers the fungus contains concentrated hormones found in several animal species. In the container of leaves, she finds a mutated beetle that possesses both insect and reptilian DNA. Ford's autopsy reveals that his hypothalamus was extracted from his brain, like the bodies from the ship. In the museum's basement, the police are startled by a mentally-ill, homeless ex-convict and kill him. Finding Ford's wallet on him, everyone except D'Agosta considers the case closed, though Mayor Robert Owen and the museum’s head of security Tom Parkinson force D'Agosta to let the exhibition proceed. On the opening night, D'Agosta orders a lock-down of all museum areas except the main exhibition hall. Frock and Margo, trapped in the laboratory wing, continue working and discover Ford's killer is after the hormones on the leaves. D'Agosta and several officers search the basement tunnels once again. They are attacked by an unseen creature, killing K-9 Officer Bradley and a police dog. D'Agosta tells Hollingsworth to evacuate the museum, but he is too late. In the main hall, the headless body of a murdered policeman falls into the crowd, causing a panic. During the hysteria, the museum's alarms are tripped and their security system goes haywire, trapping a small group of people inside. Two security guards try to restore the power but are killed by an unseen creature. D'Agosta meets Margo and Frock in the lab, where a Kothoga, an enormous chimeric beast, attacks them; they close a steel door to stop it. Margo theorizes the fungus mutated a smaller creature, and Frock says that without the leaves to eat, the Kothoga instinctively seeks the closest substitute, human hypothalami, until it runs out of targets and dies; he further postulates that the tribe knew of the fungus, and used it on a human or animal to deal with an external threat, then hid until the threat was destroyed and the Kothoga died of "starvation." D'Agosta finds a radio and tells Hollingsworth to lead the museum guests out via an old coal tunnel. Tom, Greg, and benefactors Mr. and Mrs. Blaisedale refuse to go, and CPD officer McNally stays behind to guard them; the Kothoga returns to the main hall and murders them and the S.W.A.T. officers who enter through the skylights. Margo suggests using
