Wheeler is stranded on an island of humanoid mice on the brink of population overload.

During an earthquake, a blow to his head leaves Wheeler lost from the others and suffering from amnesia. He finds himself literally in the shoes of a homeless man, and learns that the only difference between them is a simple twist of fate. A bang to the head restores Wheeler's memory, and he helps summon Captain Planet to rescue Teresa from a slum fire. Teresa and some shantytown residents decide to return to the countryside to pool their skills and make life better there.

After watching too many B-rated cyborg and gang movies , Kwame falls asleep. Shortly after, the Planeteers are called to go on a mission, where they're sucked into a freak tornado. They are then attacked by robots and have to eject from the Geo-Cruiser, separating Kwame from the others. Kwame lands into a perfect world where trash is non-existent, and is camouflaged by garbage. Meanwhile, Blight and Skumm have taken over the world with vigilante robots and gangs, and have captured the other Planeteers. They are also turned into gang members, and threaten to reak havoc on the environment. Kwame, with the aid of a new friend, must come up with a way to convince his friends that violence is not in their hearts. Once everything is back on track, the tornado returns, and wakes Kwame from what was a nightmare. He turns on the news, only to discover that gangs and violence are not far from what happened in his dream if it continues....

The Planeteers had a weird dream about being on a weird game show called "You Bet Your Planet" and they play against the eco-villians, who will win this horror game at the end?

While the Planeteers learn about organic farming, Plunder exploits Joe, a man who cannot read, by tricking him into signing a contract allowing the distribution of pesticides on a farm that he manages.

Pete, a dirt bike enthusiast, tags along with Hoggish Greedly and Rigger, until Ma-Ti and desert guide Joshua Stone show him how alive the "barren" desert really is. They must get ahead of Greedly's ORV race to save the desert from being destroyed.

The Planeteers travel to the Northwest after hearing about an old growth forest which is, literally, disappearing into thin air. After Wheeler goes off to investigate with a pretty local teenage bird watcher, Linka spots a "flying saucer" but Kwame recognizes the pilot . . . Hoggish Greedly! They discover Greedly's scam - "Sucking up" 500-year-old trees to make pressed board furniture. Outraged, they try to stop him, but his "Tree Trasher" may be too much for them.

In this story, we supposedly learn of Captain Planet's REAL first adventure... Gaia recounts how Hoggish Greedly's "Godfather" grandpa, Don Porkaloin, built Decco developments too close to the oceans threatning the sea-life. What shocks the Planeteers is that Gaia reveals she brought forth eco-warriors - 1940s counterparts of the present day Planeteers - to stop Don Porkalion. These Planeteers could also summon Captain Planet, who went about de-constructing Porkaloin's deccos. The Planeteers are left confused about whether or not Gaia's story was real, totally missing the point about building too close to the water.

Frogs around the globe are disappearing at an alarming rate! It appears that the scar on Dr. Blight's face is spreading, and she thinks that a concoction of amphibian DNA will regenerate her skin and restore her girlish glamour. Anybody for a froggy frappe?!?

Sly Sludge and Duke Nukem dump toxic waste in the Amazon rain forest, imperiling Ma-Ti's village. Ma-Ti returns to the village with Planeteers and find it in flames. When they fail to stop the fire, Ma-Ti hunts the culprits alone.

The Planeteers are still trapped in the mine while Captain Planet is still fighting Captain Pollution. As they try to get out of the mine, Kwame, Linka, Wheeler & Gi reveal their childhood stories along the way. When they got out, the Planeteers nail Plunder with help from federal agents. Then they go back to Commander Clash's island to help Captain Planet out. Captain Planet beats Captain Pollution by soaking him into some clean lava. And Pollution is gone again!

The villains hijack a television station to expound their violent and anti- environmental message.

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.

Sludge and four of the Planeteers learn first hand the terrible effects of untreated sewage when MAL and Dr. Blight shrink the EcoSub (and them) to microscopic size and put them into polluted water that Kwame unwittingly drinks. The Planeteers must battle hideous water-borne parasites in Kwame's body so that he can recover, and restore them to proper size.

The Planeteers argue what to do. Either go to Africa & save the animals or go to North America to save a rainforest. Gaia tells them that's there's an emergency at Commander Clash's island. And also that Looten Plunder's up to no good as well.vAt the island, Captain Pollution returns to fight Captain Planet causing destruction around the world. Meanwhile, the Planeteers try to stop Plunder, but Plunder puts them in a trap inside the cave with no way out.

To make a fast buck from a trash strike, Sly Sludge steals an untested microbe from Gi's scientist hero, Dr. Helix.

The blob must be stopped before it grows out of control.

An alien (named Collectore) with good intentions abducts the Planeteers, convinced that the Planet Earth is doomed and decides to collect human specimens and include them in his menegerie of assorted alien life forms.

Gi and Linka are livid when Wheeler belittles their favorite rock singer, but it looks as though Wheeler may be right after they come upon a land-ravaging, strip-mining operation run by Hoggish Greedly, but bankrolled by none other than their idol - Sky Runner!
