What is the meaning of the beatles song called "octopus's garden"?

"Octopus's Garden" is a song written by Ringo Starr with some help from George Harrison. The idea for the song came about when Starr was on a boating trip with his family in Sardinia in 1968. He was offered an octopus lunch, but turned it down. Then the boat's captain told Starr about how octopuses travel along the sea bed picking up stones and shiny objects with which to build gardens. Starr said that hearing about octopuses spending their days collecting shiny objects at the bottom of the sea was one of the happiest things he had ever heard. Starr then decided to write this song.
