Despite sounding exotically foreign, Cucamonga (Rancho Cucamonga) lies just east of Los Angeles. It used to be one of the last stops on cross country train journeys before arrival at L.A.'s Union Station and was set amidst groves of citrus trees. Nowadays, it's part of the greater Southern California basin.
It is one of three nautical-themed shorts with Sam as a pirate, along with Buccaneer Bunny (1947) and Captain Hareblower (1954).
The opening credits show a copyright date of 1948, yet the cartoon wasn't released until Feb. 11, 1950.
