Gilligan's Planet - Season 1 (1982)

Gilligan is bonked on the head by a moon melon, and has a nightmare about a world beneath the planet which is populated by aliens.

Gilligan falls into a strange lake which causes him to grow 50 feet tall. He is kidnapped by P.C. Barnaby, who wants Gilligan to be the main attraction in his circus.

Bumper is kidnapped by aliens who worship his species. It is up to castaways to find and rescue him.

Bumper hides a quartz rock in the Professor's radar device. The quartz throws off the device, and the castaways think the planet is headed for a space hole.

Gilligan discovers a cloning device and the planet is soon overpopulated.

Gilligan discovers a "size transformer" which was left on the planet by pirates. In a struggle for control of the cube, the castaways are accidentally miniaturized. The pirates return for their loot, and the tiny castaways must outwit them.

The castaways have found a map leading to the lost Barque, a spaceship that could take them back to Earth. But the tiny Quarks, the owners of the Barque, are also looking for it so they can return to their own planet.

An unmanned space probe lands on the planet, and the castaways think they can use it to send one of them back to Earth. But which one? The Professor devises a testing and training session to determine the pilot of the ship.

Gilligan stumbles into a cave and meets the Mystic Sage who gives Gilligan a Cosmic Cape which has super powers for the owner. But Gooniac has been searching the universe for the Cosmic Cape, and he's not about to let Gilligan fly away with it.

Captain Quantum and Sgt. Tyrano land on the planet expecting to find army volunteers from Aridia, whom they are to train. Instead, they find the castaways and put them through basic training.
