World 2-4 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 2-4 is the fourth and last level of World 2 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS. This is the first Super Mario World style course in the Super Mario Challenge. This is based on the level Switch It Up! from Super Mario Maker.
The level begins and immediately a P Switch falls into a 2-deep gap in the Rotating Blocks. After the P Switch expires, the player should be able to enter the pipe, which looks identical to Switch It Up! save for some missing pieces, an actual wall, and pipe raised. On the second Coin bridge is a Dry Bones. 3 3-wide holes blocked by Rotating Blocks and Coins appear after that then another coin bridge with Lava Bubbles going up and down. There are 2 Bridges and 2 Hard Blocks for safety besides the coin bridge. Another Dry Bones appears before Rotating Block stairs. There is a P Switch at the top to help the player get to the pipe below. To prevent players from going back through the second pipe, there are Hidden Blocks. After this, there are 3 Grinder pits, but if a P Switch is active, they are no threat. The is a 1-Up Mushroom in a ? Block and a Dry Bones in between the pits. To get to the next part, the player must use a Donut Block then jump up through the other Semisolid Platform. After hitting a P Switch, the path to the axe becomes available. A Red Koopa Troopa and Bowser are near the axe, however, without the P Switch active, the Koopa Troopa will fall into the lava.
