They test it on the first living subject they find - a locust. But before they can capture the other one to test for side effects, it gets away. While searching for it, they come across Vico, a boy of a local village. He becomes the source for cloning workers for the factory.

Kwame falls in love with his daughter, while also becoming suspicious of their lab assistant, who turns out to be Leadsuit, sidekick to Duke Nukem. Nukem's plan is to turn their solar convertor box into a nuclear device, so he can feed on the nuclear energy generated by the beam that saved the Planeteers earlier. The Planeteers and Captain Planet stop Nukem in his tracks, but shocks from the nuclear energy erases Dr. Pollo's memory, prompting him to set out to rediscover his inventions.

A fishing village is taught a lesson about the coral reef when Hoggish Greedly shows up. He uses dynamite fishing as a cover to rip off the coral reef remains with his new Reef Ripper.

When shown the devastating effects of pounding waves against a neighboring island village, the villagers ask the Planeteers to help stop Greedly.
