After he cowers when confronted by a ""real"" gorilla, he leaves the island and the Castaways behind.

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.

Lord Beasley Waterford, a famous butterfly collector, lands on the island searching for the world's rarest butterfly, the pussycat swallowtail.

He (like all of the other visitors to the island) leaves without sending help.

Someone kidnaps Mrs. Howell, Mary Ann, and Ginger, and then demands ransom money. The kidnaper turns out to be a compulsive gambler who fled civilization to avoid temptation.

A drab, plain-jane woman lands on the island seeking privacy. The girls give her a beauty make-over to lift her spirits, and she ends up looking like Ginger's twin.

The Professor sees the arrival of a homing pigeon on the island as an opportunity to be rescued, and immediately begins to feed it a special diet designed to strengthen it so that it can fly again.

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.

The castaways decide that they need someone to be the leader on the island, and so they hold elections.
