After eating sunflower seeds, Gilligan can read people’s minds. Everyone begins pestering Gilligan to tell them where on the island the sunflower seed bush is so that they too can have the ability.

Gilligan refuses to say but eventually gathers together enough seeds to give everyone their own supply.

Soon, many quarrels begin breaking out because everyone’s most intimate and private thoughts are now known.

When the fighting continues, Gilligan decides to burn the seed bush. The skipper says it’s the most heroic thing he’s ever seen Gilligan do.

Gilligan and Mary Anne put a message in a bottle and throw it out to sea. They later hear on the radio the bottle has been found by shipping tycoon Horris Hickinbottom, who happens to be an old flame of Marry Anne’s.

Mary Anne becomes despondent with the news that Horris is now happily married while she struggles for survival on the island. Ginger advises her the only way to get over a man is to get another man.

Ginger begins secretly ‘training’ Gilligan, the Skipper and the Professor on the finer points of charm and seduction.

Eventually Mary Anne learns the truth of why the men are being so nice to her. She declares she is now over Horris and that he was kind of a creep anyway.

After a storm, a giant telephone line is washed up on the island. The professor works out away to tap into the line to make calls.

Many numbers are ‘dialled’ but they all end in people hanging up because they think it’s a crank call or the person doesn’t speak English.

Finally, they connect to an operator but when they are instructed to insert a dime if they wish to continue the call they exhaust all their options.

After another storm hits the island, the next morning they discover the cable has been pulled back out to sea. The castaways hope the phone company will send out a repair crew, leading to their rescue sometime in the near future.

While fishing in the lagoon, Gilligan reels in an old crate. When he and the skipper prize it open they discover inside is nothing but coconuts wrapped in newspaper.

Upon closer inspection they read an article on one of the newspaper pages that reveals one of the passengers onboard the missing SS Minow is wanted for murder.

When they both share the news with the others, everyone becomes a suspect and suspicious of their fellow islanders. In a group truth session, everyone admits they knew the victim, Randolph Blake, and had reason to dislike him.

They decide to reenact the crime with a facsimile of the real murder weapon, a speargun. What they happily discover is that the ‘murder’ was in fact an accident.

The trigger mechanism of the speargun was activated accidentally by the slamming of a door.

A glamorous and rich heiress (Gza Gza Gabor) named Erika lands on the island. She says she’s looking to build a luxury hotel at a remote location, and this seems perfect.

Both the Professor and the Skipper commence falling in love with her. Ginger gives lessons to the Professor on how to woo a woman.

After a storm the next morning they discover Erika is gone and returned to the mainland. Listening in on the radio, they hear her talk about her remote island experience but she admits she has forgotten the exact coordinates to find it again.

While fishing, Gilligan reels in an old WW2 mine.

The mine has a timer attached to the top which gets activated when Gilligan’s fishing rod accidentally falls on it. Gilligan and Mr Howell then get ‘stuck’ to the mine when the rings and chains they are wearing become magnetised.

Ending up the hero, Gilligan tows the mine out into the lagoon on the back of a raft where it safely detonates.

Gilligan gets bitten by a bug. From the description, the Professor surmises it is the dreaded Manis-Carni bug. If true, this means Gilligan has 24 hours to live.

He starts showing all the classic symptoms of a Manis-Carni bug bite – aches and pains in the joints, loss of appetite and an itch. The castaways begin an hourly countdown and throw a farewell party for Gilligan.

Then, one by one, everyone else gets bitten by the same bug and are forced to begin their own countdowns.

Luckily the Professor discovers an antidote just in time. Later he learns this particular variety of the Manis-Carni is not poisonous at all and the ‘symptoms’ people were showing were common-day ailments being falsely attributed to the bug bite.

America’s #1 rock ‘n roll group THE MOSQUITOS arrive on the island seeking rest and isolation from their over-enthusiastic, dedicated fans.

They announce that their plan is to stay a month on the island. The castaways don’t want to wait that long to be rescued so they start planning how they can shorten the stay of the group. They commence acting like rabid fans who pester them night and day for autographs and attention.

Part of the plan involves the women forming a support act called THE HONEYBEES. After a night time performance, everyone wakes up the next morning to discover the MOSQUITOS have departed the island.

They leave a note saying THE HONEYBEES were too professional and they don’t need the competition.

Gilligan finds a tribal headdress, leading everyone to believe they are sharing the island with head-hunters. The castaways start busily fashioning clubs and spears in defense.

A note written by the skipper is then found saying he has been taken captive on the other side of the island by the savages.

Gilligan is appointed as the replacement skipper but this new arrangement only lasts a short time before the real skipper appears.

He confesses he faked his own disappearance in order to discover if the island would be in safe hands without him. He adds he knew the headdress was not genuine as it had a ‘Made in Paris’ label inside it.

While stocking a cave with provisions for an impending typhoon, Gilligan cops an accidental whack to the head.

Whenever he opens his mouth from then on, the radio plays. When he turns his head the radio changes stations.

When the real radio gets broken, the castaways rely on Gilligan’s ‘radio mouth’ for updates on the path of the typhoon.

When the typhoon does hit the island, everyone flees into the cave stocked with provisions. They quickly realize not everyone will fit inside. Gilligan volunteers to be the person who stays outside during the typhoon clinging to a tree. One by one, each of the castaways emerges from the cave, feeling sorry for Gilligan and joining him holding on to the tree.

During a lightning strike the cave is destroyed. Everyone survives due to the decision to join Gilligan outside.
