World 10-2 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 10-2 is the second level of World 10 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
Right from the beginning, there are three ? Blocks, one of which contains a Super Mushroom. After this, Big Goomba's Shoes come out of a Pipe. This is needed to Ground Pound POW Blocks and take out a Big Boo. After this, the player needs to climb to the top and take out a Big Stiletto Goomba to get a Key, while avoiding Boos. After going through the Key Door, the player can get another Super Mushroom if needed. Next is an area with Goombas and Goombas coming out of Bill Blasters. After this, the player must use Lifts to get across pits with Grinders. There is an accessible Big Goomba's Stiletto if the player gets out of the Big Goomba's Shoe and crosses Flimsy Lifts. After going through a Warp Pipe, the player can either go through One-Way Walls or use the shoe stomp to lift sideways Trampolines. Near the second Warp Pipe is a P Switch, which is needed to get a Key to a bonus room. If the player has a Stiletto, they can get the 1-Up Mushroom. Guarding the exit are Boos and Sledge Bros.
