World Star-2 (New Super Mario Bros. 2)

 takes place high in the sky, on top of what is supposed to be a deserted castle, where grass and other vegetation has grown on the rooftops. Super Leaves appear here, aiding Mario throughout the level. The level is abundant in Red Koopa Troopas, Donut Blocks and moving platforms.

Layout
Mario begins the level on a grassy stone platform nearby a lift on a track. Above the lift is a long ? Block containing a power-up and two coins. After another grassy stone platform, four more lifts can be found. Brick Blocks that can be broken with POW Blocks to reveal coins can be found above the first lift. Four long ? Blocks can then be found, along with two red Koopa Troopas. A Brick Block containing a 1-Up Mushroom can be found between two of the ? Blocks. A Red Ring above another lift is then encountered, along with a Koopa Troopa on three Brick Blocks. A lift that is above Donut Blocks and a Coin Block can then be found, followed by the Checkpoint Flag. A lift with a P-Switch on it can be found above a lift. After a few more lifts, Koopa Troopas, and a second Coin Block above Donut Blocks, the Goal Pole is found.
