World 5-3 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 5-3 is the third level of World 5 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
This level is a level where work is done in the main area, but work for the main area requires stuff from the sub area. At the beginning, the is a high wall. After doing the trampoline puzzle, it can be jumped over. There is a Bob-omb before the next pipe, but this Bob-omb can be used to get the trampoline by destroying Hard Blocks. After doing the P-Switch puzzle, the player can run past some coins safely. If the player has a spring while the P-Switch is active, they can get a 1-Up Mushroom. Coins block the exit until the P-Switch expires. There are Donut Blocks here to help get the player down. Next, the player must get past some Munchers. This can be done with a P-Switch if the lower path is done, but the player must be fast. Otherwise, the player must do the POW Block puzzle. After this is a Checkpoint Flag. If the player has a trampoline, they can get up high, but if not, they must do the Koopa Troopa puzzle and send a Koopa Troopa to a ? Block and release a vine. There is a Fire Flower in a ? Block above the other ? Block. There are 4 green Koopa Troopas here. If the player used the trampoline to get here, they can use their shells instead and get the trampoline up there with Mario, as well. If they have a Trampoline, getting to the top area will be easy. Otherwise, the player must do the Bob-omb puzzle to blow up Hard Blocks that block the lower part.
The player must fall past a One-Way Wall. Then, place the trampoline from the pipe on a Hard Block then jump on the trampoline. Then, run against an Conveyor Belt then jump on another trampoline. Then grab the third trampoline and exit.
The player must fall past a One-Way Wall, then use a P-Switch from a Pipe to get to the other P-Switch. The exit is below. It is possible to get the P-Switch and the next two puzzles without doing the puzzle, but it requires a Trampoline.
