Description:

At the zoo, Cordelia and her friends sneak into the hyena habitat. They are possessed by the hyenas' spirits. The spirits cause the group to act increasingly strangely and aggressively; the whole group attacking another student at a dodgeball game. A piglet mascot for the school acts panicked in Cordelia's presence, and the group later kill and eat it. Xander suspects that something has affected Coredlia after she makes a pass at him, but Giles is initially skeptical. Cordelia attacks Xander but is stopped by Buffy, while the other four possessed students attack and eat the principal. Buffy and Giles return to the zoo, while Willow guards Cordelia. Buffy and Giles meet the zookeeper, and together they form a plan to reverse the possession. The four other students find Cordelia and Willow, and are able to free Cordelia. Buffy lures the group back to the zoo, while Giles learns that the zookeeper had intended to absorb the spirits himself. When the group turns up, he takes control of the hyenas' spirits, but Buffy force him into the hyena enclosure, where he is eaten. Afterwards, Cordelia notes that she is now vegetarian.
