A new night veterinarian begins his job, reviewing the diary of his predecessor. Initially dismissing it as an easy task, he soon notices the exhibited creatures changing their postures and watching him. On the fourth day, spores enter his system while trying to heal a cicada, distorting his perception. He learns a vicious one-armed monkey hunts beast healers, and he panics as a petrification process seems to start on his arm. The episode ends with him shouting a challenge into the dark, uncertain if the threat is real or hallucinated.
