World 19-11 is the eleventh of World 19 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS. This level is one of four levels that has a Castle in the sub area, but not the main area. It is exclusive to the Coursebot.
Near the start of the level, there are two Brick Blocks and a ? Block containing a Super Mushroom as well as a set of one-block high stairs. There is also a Winged Cheep Cheep that comes from the far right of the screen. After a Mushroom Platform and a Red Koopa Troopa, the player goes across bridges while encountering three more Winged Cheep Cheeps. When the player encounters two Winged Cheep Cheeps near each other, they also encounter Note Blocks. After these Note Blocks is a bridge with a ? Block containing multiple coins and a Brick Block with three Winged Cheep Cheeps coming toward the bridge. There is another bridge with coins and a ? Block containing a Super Mushroom on a Fire Flower. This bridge is guarded by a Red Koopa Troopa. After three more Note Blocks, the player encounters tons of Cheep Cheeps while on bridges and Note Blocks in the middle before reaching a Warp Pipe next to a giant impassible wall.
In the subarea, the player lands on an area in the same shape of the starting area, except there are coins instead of Brick Blocks and ? Block and the Winged Cheep Cheep is now Big. After a Lava Bubble, there are two Semisolid Platforms. One is protected by three Winged Cheep Cheep, the front one being big, but contains a row of Brick Blocks and ? Blocks, one of which contain a Super Mushroom on a Fire Flower. The other is guarded by a Red Koopa Troopa. Between the second Semisolid Platform and the nearby ground, there are Donut Blocks on either side of a Fire Bar, which is below a ? Block containing a 1-Up Mushroom. After two Lava Bubbles, there is a bridge guarded by three Winged Cheep Cheeps with Brick Blocks above. Above the Brick Blocks are a Hammer Bro. and the first Pink Coin. The Checkpoint Flag is nearby.
After the Checkpoint Flag, there are two Donut Blocks and a ? Block containing a Super Mushroom on a Fire Flower. After going down, the player needs to get past Cheep Cheeps from Pipes. There are two Pink Coins in this area. The player goes up through Donut Blocks. Then they can either go down by Ground Pounding Brick Blocks and get past Donut Blocks and Cheep Cheeps from a Pipe to get a Pink Coin, or they can go right to continue. The player then needs to cross a bridge protected by Cheep Cheeps from a Pipe. A Pink Coin is above the bridge and is protected by Brick Blocks. On the other side of the bridge is a Key Door, which can only be unlocked by collecting all Pink Coins. However, they aren't required to continue, as the Key Door takes the player to an area of three ? Blocks with one of them containing a 1-Up Mushroom before merging back into the same area where the player came from.
From here, the player needs to go through a corridor of Brick Blocks with only one ? Block which contains a Super Mushroom on a Fire Flower. However, the player can't go through the corridor due to a thin wall of Brick Blocks. Luckily, there is a Magikoopa that comes from a Pipe that turns the Brick Blocks into other things. After getting past two Hammer Bros., the player gets through the corridor. After a Red Koopa Troopa, the player needs to get through more Brick Blocks and get past four Brick Blocks on top of each other. Like before, there is a Magikoopa from a Pipe to help. However, there is a Big Red Cheep Cheep which makes the player keep moving and a Green Koopa Troopa and 1-Up Mushroom above. After getting through the four Brick Blocks, the player can go through the Warp Pipe back to the main area. Back in the main area, the player needs to get past a Winged Big Cheep Cheep before encountering Hard Blocks forming stairs. To the right is a Note Block and the Flagpole. The player must grab the Flagpole before a Magikoopa transforms it.
