World 16-3 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 16-3 is the third level of World 16 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
The whole course is about the player crossing a huge pit by traversing on Flimsy Lifts while avoiding Red Koopa Paratroopas. A majority of coins can be grabbed by the player. However, a few of them are between Spike Traps, which the player must use a Red Koopa Troopa's shell to get them. About halfway through the course, two Mushroom Platforms will look like they are holding up two Flimsy Lifts, but they aren't. Bonus Music plays throughout the course.
