Ma-ti is fooled when Looten Plunder disguises himself as a scientist, promising to clear the air all over the world, including his tribe's village in the rainforest. After Wheeler and the tribe are trapped inside one of Plunder's domes, and Ma-ti is captured after discovering Plunder's scheme, the remaining Planeteers have to find them both and bring Plunder down.

Linka and Ma-Ti visit a friend, Juan, in Central America. While there, Juan's parrot, El Profesor, leads them to a secluded "bird paradise" when suddenly, a giant, metallic bird appears. All the birds, including El Profesor, follow it and so do Linka and Ma-Ti. They soon find themselves locked in a huge aviary, courtesy of Hoggish Greedly, who's running an exotic bird smuggling venture. El Profesor escapes and leads the Planeteers back to the aviary, where they summon Captain Planet, who closes down Greedly's "fly-by-night" operation.
