The Skipper fears that the island is full of 'voodoo' when he thinks that Gilligan has been turned into a monkey.

The castaways hear on the radio that a plane is going to be flying over their island, but they will be unable to contact them because their transmitter is broken. Gilligan overhears the Skipper dreaming about repairing a transmitter as he sleeps. The Skipper is unable to remember how he fixed the transmitter from his Navy days, so he attempts to have the dream again, but is unable to fall asleep. Each castaway attempts to help by sneaking two tranquilizers into Skippers mango juice. When Gilligan hits the transmitter out of frustration, it suddenly works! However, when he hits it again in an effort to show the other castaways how he fixed it, it falls completely apart just as the plane flies overhead.

When Gilligan finds an old airplane hidden in the jungle, the Castaways discover a long-forgotten aviator living on the island.

The castaways decide that they need someone to be the leader on the island, and so they hold elections. As you might imagine, both Mr. Howell and the Skipper imagine themselves to be the natural choice to lead the Castaways in their island society. However, when the votes are counted Gilligan is elected president of the island! Just as we recently learned in Florida, every vote counts!

The Castaways are faced with running out of food, when a blight threatens to destroy many of their plants. When Gilligan finds a duck in the lagoon, a difficult decision must be made. Should they eat the duck, or tie a rescue note to it and let it fly away?

Gilligan discovers a special tree sap that can be used to make a good tasting pancake syrup. Then the professor discovers that the same tree sap also makes a super glue, that may allow the castaways to repair the Minnow. Could it be that the Castaways may finally escape from the island?

Mr. Howell discovers a gold mine on the island. He then hires Gilligan to work in the mine. When gold fever strikes the castaways and Mr. Howell is unwilling to share the gold, they begin to charge outlandish prices for the supplies and food that Mr. Howell needs. When the professor repairs the life raft from the Minnow, they all climb in hoping to reach civilization. However, the combined weight of the gold that everyone smuggles on-board the raft causes it to sink. Another rescue foiled!

While digging, the Skipper uncovers a carved statue of a Tiki God. He then believes a curse has fallen on him for disturbing the resting-place of Watubi, and that his days are numbered. Gilligan dresses up as Watubi, and performs a special ritual dance that the Skipper believes will lift the curse. It is an earth-shaking experience!

During Christmas, the Castaways get homesick and remember the first day they were shipwrecked. When Santa Claus "appears" on the island, many suspect he is the Skipper in costume. However, just as Santa departs while wishing the Castaways a Merry Christmas, the Skipper appears from the other direction.

Mr. Howell loses $3 million to Gilligan in a golfing contest. Mr. Howell then tricks Gilligan into trading for a worthless oil well that he owns. When the radio announces that the oil well is a gusher, Mr. Howell sets his sights on winning it back. However, just as he succeeds in winning it back, the radio announces that the gusher was a mistake!

Talk about a painful irony: though surrounded by water, the Castaways suddenly discover that their supply of fresh drinking water is running out. When they pool all available drinking water together and decide to ration it, they discover that they will each receive only a few drops per day. Of course, most of the castaways sneak water from the community supply when Gilligan is standing watch, but return it when the Skipper catches them. Just when all seems lost, Gilligan saves the day!

The Castaways are captured by a Japanese sailor who thinks that WWII never ended. When the other castaways are captured, it is up to Gilligan to save them.

A well known crook tries to evade police after a heist and is dropped off on the island by his henchmen to be picked up later after the heat cools down. After being discovered by Gilligan he poses as a doctor but the truth is soon revealed. Now he must keep the castaways at bay and get off the island with his money. Of course with Gilligan on the island this is much easier said than done.

In a test of a deadly new missile, called "Operation Powder Keg," the Air Force chooses an "uninhabited island" which just happens to be Gilligan's Island. When the rocket lands and does not explode, Gilligan is chosen to crawl inside to defuse it, because he is the only one that can fit inside.

Gilligan discovers a jungle boy living on the island. He shows them a hole in the ground that causes objects to float, and the professor theorizes that it is expelling either helium or hydrogen. He immediately sets to work building a large balloon, with the hopes of carrying one of them back to civilization.

Angry because the men haven't kept their promise to build them private houses, the women decide to move to the other side of the island in protest. Gilligan and the Skipper dress as a monster, in an attempt to frighten the girls and cause them to come running back.

Handsome surfer Duke Williams rides a giant tsunami to the island. At first, the castaways are excited as Duke thinks he will turn around and surf back to Hawaii (and send help). However, after seeing Mary Ann and Ginger, he decides he may want to stay for a while. The castaways must come up with a plan to make him want to leave for Hawaii.

A fall from a coconut tree gives Gilligan an inflated nose and a deflated ego. When Gilligan decides he wants the Professor to perform plastic surgery on his nose, the Professor pretends to perform the surgery, and instead, relies on the recuperation time behind the bandages to allow the swelling to go down. When the bandages are finally removed, Gilligan decides he is happy with his old nose!
