Similar to Water Babies, redheaded 'merbabies' materialize out of the crashing surf and proceed to the sea floor where they conduct a circus along with a variety of sea creatures. Monstro makes a cameo appearance in this short.
- Because Disney recruited animators from Metro-Goldwyn-Mayer to help production of Snow White and the Seven Dwarfs, "Pipe Dreams" and "The Little Bantamweight", Silly Symphonies that were rebranded as Happy Harmonies, were made for the studio. MGM bought the copyrights for these two from Disney and released them as part of their Happy Harmonies series. These two were the last two shorts in the Happy Harmonies series before MGM terminated Hugh Harman and Rudolf Ising's subcontract in 1937, though they were later rehired back, but no longer worked together after they got rehired.
- This short and "Winnie the Pooh and a Day for Eeyore" are the only two Disney cartoons to be outsourced to another studio (this one because Disney borrowed animators from MGM to finish Snow White and the Seven Dwarfs). In the case of "Merbabies", it would be made by Rudolf Ising and Hugh Harman over at MGM, who worked with Walt in the early years.
