The Rangers discover the Kelzaks planting strange seeds, along with a monster called Florabundacus. Cam is refused being allowed to bring the seeds to botanist Dr Belrab by his father, who has long kept a promise to his deceased wife to keep their son out of harm's way by not letting him become a ninja. Going anyway, Cam ends up smack dab in the middle of a plot by Lothor's minions to wrap the city in Florabundacus' roots and vines.
