History

Season 2

Episode 2x06 - "Fragments": A male pleski named Jack. When in contact with the native Siberian fungus Cordyceps siberienses, ACTH levels in pleski are increased which in turn causes extremely violent behavior. Gerald, Rachel, and Henry Foss's research with Jack prove that when the fungus is absent from their system, pleskis are a calm, intelligent species that are capable of communicating via sign language.
