Thundarr, Princess Ariel, and Ookla encounter a train carrying Death Flowers (whose pollen can hypnotise both humans and Moks) being transported by the Carocs (a race of crocodile people) to a wizard that they work for. The episode introduces Tye, a swamp-urchin, who agrees to aid Thundarr on the basis that he capture the train and give it to her. Tye would reappear in Season 2's "Last Train to Doomsday".[10]
