World 5-3 (New Super Mario Bros. 2)
From the Super Mario Wiki
Players find a Pipe Cannon at the beginning, but there are spikes surrounding the ground, so players must use the pipe. A ? Block is found after the Pipe Cannon is used, where it contains a Fire Flower. A Gold Ring is found, alongside a red Koopa Troopa on the slope. Where the slope ends, players find another Gold Ring and another slope, but this one has Goombas as well as a red Koopa Troopa. The end of the slope has another Goomba. There are three unconnected slopes, and the second slope has two Goombas. When players fall from the last slope, a Checkpoint Flag is found. Now there are three Pipe Cannons. The Pipe Cannon sends players to slanted ground, where there is an inaccessbile Star Coin. The middle pipe sends players straight up, where they will see a single ? Block, with some hidden ones. The above block contains a Mini Mushroom that is used for obtaining the second Star Coin, with some small Goombas. If players land on ground, another Pipe Cannon that shoots players over the spikes can be accessed. A Pipe Cannon below sends players through an orange platform. Another Pipe Cannon to the left of it sends players through a Red Ring. Taking the left or right Pipe Cannons at the Checkpoint Flag sends players to these pipes. There are some bricks and a ? Block that a red Koopa Troopa is walking around on and a Gold Ring with a slope nearby. After players slide down the slop, another slope with some Goombas awaits, which leads players to the third and final slope, which contain Koopa Paratroopas and five pipes. The first cannot be entered, the middle takes players backwards, the far left takes players to ground, where players can climb stone steps to find the Goal Pole. The middle left shoots players to the top of the Goal Pole.
