Pass the Vegetables, Please

Gilligan finds a crate of radioactive vegetable seeds. The plants grow quickly and grossly misshapen, but the Castaways are so hungry for new items in their diet that they consume them quickly. The plants, when eaten, give the castaways super-human powers. Of course, after he realizes that the vegetables are radioactive, the Professor saves the day by making a homemade soup to absorb the radioactivity.
