1x18 - Jayce and the Wheeled Warriors

The planet Baz sprays all their plants with pesticide to keep the Monster Minds from invading their planet, but the Monster Minds send vines to cut them off from outside shipments of food. Zena, the princess of the planet, contacts Jayce for help, but when the Lightning League arrives on Baz the pesticides begin to kill Flora, and the Monster Minds prevent them from taking her to safety.
