"Pinocchio" is a 1940 American animated musical fantasy film produced by Walt Disney Productions and based on the 1883 Italian children's novel "The Adventures of Pinocchio" by Carlo Collodi. It was the second animated feature film produced by Disney, made after the first animated success "Snow White and the Seven Dwarfs" (1937).

In the Walt Disney film "Pinocchio", the Dogfish is named Monstro (which is Portuguese, Esperanto, and archaic Italian for "monster") and is portrayed as a terrible sperm whale with massive jaws, both of which have sharp teeth, and a grooved underside like a rorqual.

He is first mentioned in a message from the Blue Fairy about Geppetto, who, sailing to find Pinocchio, has been swallowed by the whale. They search for him, but are frustrated by the fear the various nekton display at the mention of his name. After finally discovering him sleeping, he suddenly awakens and swallows Pinocchio, who discovers Geppetto in Monstro's throat.

Pinocchio frees them by starting a fire, the smoke of which prompts Monstro to sneeze them from his mouth, whereupon he gets angry and pursues them. Pinocchio pulls Geppetto into a cove where Monstro smashes against the rocks surrounding it but is unable to reach them.
