"Three Little Fishies", also known as "Three Little Fishes", is a 1939 song with words by Josephine Carringer and Bernice Idins and music by Saxie Dowell.
The song tells the story of three fishes, who defy their mother's command of swimming only in a meadow, by swimming over a dam and on out to sea, where they encounter a shark, which the fish describe as a whale.
They flee for their lives and return to the meadow in safety.
