Listening World is a location in Mario's Early Years! Preschool Fun. It is one of the six islands in the game and is represented by a mooing cow.
In this world, the player is presented with three different barnyard animals (Cats, dogs and frogs are also included) and a sound bite of an animal call. The player then must match the call with the animal. After the player selects the correct answer, a character pops up to encourage them, then after five correct answers, the player goes back to the island select screen via a pipe.
The area is set on a stereotypical livestock farm, with hay acting as the platforms.
