Cow in the sea. Cow in the field. Does a sea cow say "Moo" And eat grass for its meal? DOES A SEA COW SAY "MOO?" Oh, that can’t be true! It chirps and it clicks and it Whistles instead, And grazes on sea grass In shallow sea beds. When an alien lands on earth he is very befuddled by the names of the bizarre creatures he finds in the sea, and his imagination starts to run wild with all the possibilities! A little boy soon explains what the creatures really are with some very funny fish facts, too.
