Wet-Dry World is the eleventh course of the game, featuring a "town" with an adjustable water level. By touching any of the crystal gems in the course, the water level is raised or lowered to the height of the crystal gem used. Additionally, Mario's height as he enters the painting determines the water level immediately after entering the course (low, medium, or high). The course has a tunnel with a loading zone to take Mario back and forth between the main area and "downtown".
There are a total of 152 coins in the course, with 107 coins in the main area and 45 coins inside the town. The coin limit in this course can be raised through glitches, namely cloning and coin spawner cloning using the chuckya.
