|Genre(s)||New Super Mario Bros. X|
1-6 is the sixth level for World 1 in New Super Mario Bros. X. One of the game's few underwater courses, the level is, as the name implies, filled with Bloopers. The player must have found the normal exit in World 1-5 to reach this course.
This course has many pipes, most of which either pump a current that will force the player in a certain direction or expel Bloopers, Rip van Fishies, and Sushies. Many of the pipes that expel water rotate, in places requiring the player to wait for this to happen to be able to continue or forcing them to take a longer path rather than what would be a shortcut. Many coins in bubbles litter the course.
- Star Coin 1: In a high up alcove just past the second Question Block containing a Fire Flower.
- Star Coin 2: In what looks to be a closed off area at first. The player can reach the coin by swimming under the red pipe beside it, under the portion of the screen the camera shows.
- Star Coin 3: Through a Warp Pipe in the area with many rotating pipes that pump out water. This secret room also contains a pair of Blooper Nannies guarding the Star Coin.
