This fanciful nautical adventure stars a winsome cat named Zoom, who stays indoors paddling in the sink or sailing in the bathtub all night when other self-respecting cats are out mousing and howling at the moon.

One day Zoom finds in his Uncle Roy’s diary a map of the sea and how to get there, which leads him to the huge house of the beautiful Maria. When, with the turn of a large wheel, mysterious Maria launches him on a wonderful sea voyage, the first of Zoom’s adventures begins.
