Shape World

Shape World is a location in Mario's Early Years! Fun with Numbers. It is one of the seven islands in the game and is represented by a triangle, a circle and a square.

In this world, the player has to select the shape indicated. The first level involves selecting the requested shape to eventually make a train. The second, third and fourth levels involve the creation of a progressively more complex train with more shapes of different sizes. After the player selects the correct answer, a character will pop up to encourage them, then after 5 correct answers they will move on to the next room via a pipe.

All four areas are reminiscent of Dinosaur Land with the hill background and the cliff ledges; the player exits through a blue pipe in the last room.
