World 4-3, is the nineteenth level of Super Mario 3D Land.
World 4-3 begins with Mario jumping onto various rotating blocks. Across these blocks is the level's "Coin Heaven." Using an Exclamation Block, Mario makes his way to the level's Checkpoint. After the checkpoint the level becomes purely rotating blocks, only with Paragoombas trying to attack Mario.
- Star Medal 1: On the edge of the long blue rotating block near the very beginning is where Mario will find the first Star Medal.
- Star Medal 2: The end of the level's "Coin Heaven" is where Mario finds the second Star Medal.
- Star Medal 3: The third Star Medal is tossed down by a Toad high above the level. Zooming in on the Toad via the binoculars near the Checkpoint will make him throw the coin near one of the rotating blocks in the last leap of the level.
