Verminous Skumm creates a substance that, when placed in water, will mutate its drinker into a rat-resembling character who willingly serves him. The Planeteers go to stop him, but Wheeler falls into a vat of it, and Linka and Gi are splashed, so the others must hurry to recover an endangered plant Ma-Ti's friend the Shaman believes may cure them. Meanwhile, Skumm plans to place the liquid in Ma-Ti's village water supply, then the Amazon to infect the country and perhaps even the world.
Did You Know?
Planet! Hey - Planet! What're you gonna do with me?
Hm, good question. It's either the police station, or the zoo.
The zoo, the zoo sounds good! They never have rat-exhibits at the zoo. I could start a new trend.
