Merbabies (film) Silly Symphony cartoon; released on December 9, 1938. Actually produced for Disney by Harman-Ising Studios, directed by Rudolf Ising and supervised for the Walt Disney Studio by Ben Sharpsteen, Dave Hand, Otto Englander, and Walt Disney. The workload at the Disney Studio was getting out of hand, so Walt decided to help his former colleagues (from Laugh-O-grams) by passing some work their way. A sequel to Water Babies, in which ocean waves change to form merbabies who 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.
