Erika Tiffany Smith lands on the island looking for a place to start a new resort, and a new husband.

Gilligan suggests a beauty contest to decide which of the three women will become "Ms. Castaway." Mr. Howell attempts to sabotage the other contestants by spreading glue on the stage before Mary Ann's big dance scene, and by shooting spit-wads at Ginger while she performs. The Professor blows pepper at the stage when it is Mrs. Howell's turn. Then, when all the competitions are complete, the final decision rests with the judge.....Gilligan!

The Castaways make a silent movie in the hopes that it will be discovered by someone who will rescue them.

A popular American singing group, the Mosquitoes (Bingo, Bango, Bongo, and Irving), land on the island hoping for some quiet and relaxation on a deserted island.

A mad scientist lands on the island and takes the Castaways to his castle . . . on a nearby island . . . to perform experiments on them.

The exiled president of a revolution-torn country visits the island.

A NASA satellite with a TV camera, accidentally lands on the island instead of the intended target: Mars. The castaways try to communicate their S.O.S. when the camera is operational. However, with the help of a Gilligan goof-up, the castaways are covered with glue and feathers, and the NASA scientists mistakenly believe they are seeing the first proof of life on Mars.

Gilligan has the winning ticket for a South American sweepstakes.

Two Russian Cosmonauts land on the island in their space capsule. Since the cosmonauts keep a tight guard on the space capsule, the castaways must come up with a way to smuggle one of them into the capsule in order to send back help after the cosmonauts are rescued.

While fishing, Gilligan pulls a WWII mine out of the lagoon. When the Professor is unable to deactivate the mine, Gilligan tows it back into the lagoon, where it harmlessly explodes.

An experimental robot launched by the Air Force parachutes onto the island. The professor reprograms the robot to walk to Hawaii ("one hundred eleven hours"), but the "lucky" rabbit's foot that Gilligan secretly stuffed into the robot causes it to malfunction upon arrival in Hawaii.

The Castaways are frightened as the sounds of battle, including hand grenades and machine guns, rock the island. The culprit turns out to be a gorilla who has found an old WWII weapons cache.

A cage containing a lion washes ashore in the lagoon. After Gilligan removes a thorn from his paw, the two become pals. When the Castaways run out of food, however, Gilligan thinks the lion has consumed the Skipper.

The radio reports that Mr. Howell has been rescued and is spending all of his money. Obviously, there is an imposter! The real Mr. Howell is frantic, and offers a reward to the person who can come up with a plan to get him back to civilization. Meanwhile, the imposter falls off a luxury liner and ends up stranded on (you guessed it!) Gilligan's Island. There the imposter conks Mr. Howell on the head with a coconut, changes clothes with him, and attempts to continue his masquerade as the millionaire.

A ghost appears on the island and tries to scare the Castaways off. The castaways turn the tables by dressing in sheets and roaming around the island to scare the visitors off the island.

A radio bulletin states that the minister who married Thurston and Lovey Howell (the Reverend Buckley Norris of Boston) was a fraud, and that the Howell's marriage is actually null and void. The stress causes disagreements and separations between the Howells. In the end, it turns out that the radio announcer was at fault: While he mistakenly reported that "Buckley Norris" was the fraudulent minister, he was supposed to say "Borris Nuckley."

A huge meteor lands on the island, causing everything nearby to age very rapidly. The Professor determines the rapid aging is being caused by strong cosmic rays (he makes this determination by using his bamboo Geiger counter!).

A native family from another island comes seeking a husband for their lovely, large, robust daughter.

The Professor thinks that the island is sinking, which causes the Castaways to panic. As it turns out, Gilligan has mistakenly moved the Professor's measuring stick, so the panic was a false alarm.

Gilligan and the Skipper hear a radio broadcast telling of the collapse of the Howell financial empire. The castaways attempt to help them develop skills in order to compete in the working world.

Gilligan's mouth becomes a radio after he is accidentally hit on the head. When their regular radio is broken, Gilligan becomes their sole source of information on the approaching typhoon.

The Skipper worries that something is going to happen to him, so he begins to train Gilligan to be a leader. The Skipper then disappears leaving Gilligan in charge, with predictable results!

Gilligan's thinks he is doomed after being bitten by a yellow and green bug. Soon, the other castaways are also bitten by the same bug.

A crate containing coconuts is wrapped in an old Honolulu newspaper that read that one of the Castaways are being sought in a murder investigation. The castaways become suspicious of each other and decide to recreate the events of the night before they sailed, in order to solve the Randolph Blake murder case.

A storm washes up a Trans-continental telephone cable up into the lagoon. Once again the Castaways are given hope for a rescue, as the Professor manages to break into the cable and rig up a telephone so they can dial out for help.
