This proposal bears a rare example of Lennon's signature, also the story shows a different approach to that used in the film. The Beatles hitch a ride in a Yellow Submarine and accompany an old sea captain Barnacle Fred, to the land of submarines through a Sea of Solid Ice, War of the Waves and Sea of Green. Guided by a chartreuse Boob ..a pompous upper class seal.. they reach the Land of Submarines and finally help the beautiful Submarine folk by ridding them of their scourge ...a huge gigantic big red mean fat sea monster...a nervous compulsive eater...who picks his teeth with submarines.. by explaining to the monster ...that its uncouth for one to pick one's teeth even in private.
