The Biological stink problem

At the Streak Temple, Gabriela surveys Gilbert, Camélia, Al, and Karoo, frustrated when they answer one another instead of her. Kion arrives and asks about Grandfather Amur, while Makucha calmly helps Gabriela settle down. During the third biology investigation, a strange stink is released. Gabriela mistakenly blames Aya, who explains she discovered the abnormal reaction earlier that morning. The scientists realize it is a recurring biological mystery and begin investigating its cause.
