Instinct

A stylish otter arrives at a once-peaceful animal school. The students begin imitating the otter, judging one another’s fashion and appearance. As they become obsessed with dressing up, they gradually lose their individuality. The animals grow increasingly civilized as they imitate human culture—until a human girl transfers to the school one day and sparks a new trend. Competition and conflict soon escalate, and eventually their suppressed instincts erupt, plunging the school into chaos.
