This cartoon is similar to the 1938 Looney Tunes cartoon "Wholly Smoke", as both involve normally good characters trying something dangerous.
This short is rarely shown on the Turner Entertainment networks due to smoking. In fact, other than Tom and Jerry (includes the two Spike and Tyke shorts) and Droopy cartoons, no other cartoons from Metro-Goldwyn-Mayer rerun on Boomerang USA on a daily basis.
Due to Disney's high volume of cartoon production, the studio got a little ahead of itself. Disney contracted out the production of three Silly Symphonies shorts - "Merbabies", "Pipe Dreams", and "The Little Bantamweight" - to Hugh Harman and Rudolf Ising. Of the three, Disney only kept one ("Merbabies"), with the other two being sent to MGM, who released them as Happy Harmonies cartoons.
Like most Happy Harmonies cartoons, the cartoon is available on YouTube without copyright protection.
