World 2-3 (Super Mario 3D Land)
World 2-3 is the third course of World 2 in Super Mario 3D Land. Its platforms and music are based off of Super Mario Bros. The icon is a section of the course's colored blocks with smaller sections floating above them.
Mario starts the stage on a platform in the shape of his appearance in Super Mario Bros. There are three P-Switches — two located at Mario's overalls' buttons, and the other in Mario's ear. A Propeller Box can be found here. Past some giant blocks is a platform in the shape of an 8-bit Super Mushroom; here, a P-Switch causes a line of coins to appear. Near one of the mushroom's spots, there is a Brick Block hiding a Tail Wheel. Twirling it with Tanooki Mario's tail causes the platform to rise, uncovering a Red Ring can be reached.
Past the Super Mushroom platform is a set of yellow and blue blocks with Paragoombas, coins and a green + Clock; the path of blocks leads to a platform in the shape of an 8-bit Princess Peach. Another Tail Wheel is found here, and raises the blocks composing Peach's dress stripe; this leads to a section with Goombas and Coin Coffers, as well as a Super Star surrounded by coins in a heart formation. Ahead, a Warp Box leads the character to a grassy area, with a background that resembles the Super Mario Bros. style. A classic Hard Block staircase is used to reach the Goal Pole; inside the fortress past it is a hidden Warp Box which takes Mario to a platform in the shape of an 8-bit 1-Up Mushroom, which has an actual 1-Up Mushroom and another Warp Box that returns him to the grassy area near the Goal Pole.
