World 15-1 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 15-1 is the first level of World 15 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
At the beginning of the level, there are two ? Blocks, one of which contains a Yoshi Egg. Using Yoshi, the player can get over a wall using the Flutter Jump. Arrow Signs and coins help the player go in the right direction. On the other side, there is a little ground with two Brick Blocks and a ? Block containing a Super Mushroom above it. Then, a large pit appears which can only be crossed with Yoshi's Flutter Jump or Spin Jumping in midair. After the pit, a bit of ground with Semisolid Platforms around and five enemies of three different types. At the end of the ground section is a Warp Pipe that gives Yoshi Eggs. It then splits into to paths. The lower path is a dead-end, but there is a Pipe that gives Super Stars. The upper path just loops to the left, but gives more height. This area is guarded by a Fire Piranha Plant and a Big Venus Fire Trap. If the player goes left (as going up is tricky, but not impossible even with just Mario), they encounter Giant Bob-ombs surrounded by Hard Blocks. There is a nearby Burner to help the player get through. If they get past the Giant Bob-ombs, the player must get rid of Piranha Plants then activate a Flimsy Lift to get a Fire Flower from a ? Block. Going to the right either by a tricky maneuver or using Yoshi's Flutter Jump from the left, the player encounters a Koopa Troopa, which can be used to get past Big Piranha Plants. The only other way is using fire from either the nearby Burner or Fire Piranha Plant. If the player goes down past Donut Blocks, however, they can get a 1-Up Mushroom from a ? Block before going back. After the Big Piranha Plants, there is a large area with four Giant Bob-ombs surrounded by Hard Blocks. At the beginning of this area is a Pipe that gives Yoshi Eggs, as well as a Burner. The area is also divided into two paths. The higher path is the only path to have Yoshi at the top of the Goal Pole, as the lower route, though having less Giant Bob-ombs than the upper, only leads to the lower part of the Goal Pole.
