Jayce and the Wheeled Warriors (1985)

S1E6 Flora, Fauna and the Monster Minds

Monster Minds are secretly placed on the Pride to taint the water supply. When the contaminated water is ejected, Herc is compelled to land the Pride to look for a new water source and a Cobalt-49 crystal that can fix the guidance system, which has been damaged by the vines. Unbeknownst to them, this is a scheme orchestrated by Saw Boss.
