Well that's not completely true. The voice of Mel Blanc as Sam the parrot is very funny, but it takes nearly half the episode for the bird to make an appearance, only heard as a voice in the first half. The castaways think that there are a group of gangsters on the island and are desperate to protect themselves and find their boat. But out of nowhere the periodic appears, and thinking that there are jewels hidden somewhere, the Howells tried to seal Sam. It's a great chase between Thurston and Sam, and of course the smarter Sam wins.
There are several words that set Sam off including jewels and boat, and of course the explanation involving boat is never revealed and jewel refers to something unexpected.
It's obviously the presence of the voice of Mel Blanc that provides most of the laughs as it did as the cockatoo in the Lucille Ball movie "The Fuller Brush Girl". But it's a silly idea that has never really developed or fully explained, other than to say that there are a lot of unknown parts of the island where anything can turn up at any time.
