Blockade Runners

S1, E18: Mock training battles are interrupted by Dar, a robot sent from Baz in search of help from Monster Minds. The people of Baz are starving since they have defoliated the planet to prevent Monster Minds from growing there. Jayce and friends bring food and fight the Monster Minds. Flora's life is in danger from the defoliant so Jayce turns it off. He then makes defoliant bombs which surround the planet's atmosphere, but don't hurt the soil. All is saved and Monster Minds are forever kept from the planet.
