Merbabies is a Silly Symphonies animated Disney short film. It was released on December 9, 1938. It is a collaboration between Walt Disney and Harman and Ising, the latter studio having donated artists to Disney to work on the production of Snow White.
Various redheaded "merbabies" materialize out of the crashing surf and are summoned to a playground on the floor of the ocean for an underwater circus. When a whale blows them all to the surface, they disappear into the waves from which they came.
