Synopsis by Hal Erickson
The story begins along the waterfront, as erstwhile gondolier Tom pilots a canoe fashioned from a washtub, rapturously singing "Santa Lucia" to an audience of disinterested seagulls. Likewise, Jerry makes his entrance rowing along in a teacup and warbling the same tune. Tom forgets his serenade and attempts to make a meal out of Jerry, but the mouse is stolen by another cat (who looks more like a dog!) This leads to a merry chase all around the waterfront, with ample time out for a re-enactment of the "mirror" routine from the Marx Brothers' comedy classic Duck Soup (1933).
