World 14-1 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 14-1 is the first level of World 14 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
The level is a slow autoscroll level. Soon after starting, a group of Big Boo Buddies on tracks will get close to the start. This will allow the player to get in it quickly. The level continues on Semisolid Platforms with coins above them. There are also Donut Blocks. After it ends, the Big Boo Buddies fall off screen. There are two Brick Blocks and a ? Block containing a Super Mushroom in it, but the top part of it is protected by regular sized Boo Buddies. After this, the player must continue on Semisolid Platforms while avoiding three groups of Boo Buddies, two of which are winged. The player must then climb a Vine. There is a Super Star on a track which will help the player get past the last Big Boo Buddies. If the player still has the Super Mushroom, they can break through the Brick Blocks and possibly get the top of the Goal Pole. But if not, they have to take a short detour and not get the top.
