World 17-4 (Super Mario Maker for Nintendo 3DS)

World 17-4 is the fourth level of World 17 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.

Course layout
Near the beginning, there are three Donut Blocks, four coins, and a Thwomp. Not long after are three groups of decreasing numbers of Donut Blocks, five coins, two Thwomps, a ? Block containing a Super Mushroom, and an unchained Chain Chomp that can be defeated by using a Thwomp to land on it. After this are two sets of five Brick Blocks with coins to help lead the player, and an unchained Chain Chomp on the top. The player can then walk on a Semisolid Platform to another area with three Chain Chomps on Hard Blocks, a ? Block containing a Super Star to take the Chain Chomps out, and a Fire Flower on Donut Blocks below a bridge. The player also can use Donut Blocks and enter the Warp Pipe below the Semisolid Platform top. In the sub-area, the player falls onto four Lifts with a Chain Chomp on the left. The player must then ride them through an area with Fire Piranha Plants and Goombas from the Pipes above. At some point, a Super Mushroom on a Fire Flower flies through the stage. At the end is a winged POW Block and a house made out of Hard Blocks and red Mushroom Platforms. After taking the Warp Pipe back to the main area, the area is very similar to Be Brave & Get Up Close! from Super Mario Maker with the only differences being an added ? Block and two missing Big Chain Chomps.
