S1E20 Seeds of Destruction

A demon seed takes root in a professor's plant, quickly seizing control of the entire building. Once the plant is destroyed, the demon transfers itself to another plant located in the park. Kylie, believing this new plant to be a harmless Amazonian species, is completely unaware of its true nature as a civilization-threatening demon. The EGBs must act fast to prevent Kylie from freezing the demon and sending it back to the Amazon before it's too late.
