Did Somebody Call a Plumber?

Did Somebody Call a Plumber? is Coursebot's first official course in Super Mario Maker, released on November 4, 2015. It is set in the ground theme for its main area and in the underground theme for its sub area, as well as in the Super Mario Bros. game style.

Layout
The level begins with a Brooklyn setting, with the first two Warp Doors leading to what appears to be Mario Brothers Plumbing. The next Warp Door leads Mario up to a warp pipe. The next segment is a throwback to the first Mario Bros. level, except that the Shellcreepers are replaced with Koopa Troopas. Afterwards, Mario must traverse a segment filled with warp pipes that leads to a Checkpoint Flag. Afterwards, Mario must head upwards to kick a Koopa Troopa shell into some Brick Blocks, then traverse a segment with mushroom platforms and a Lift, with another segment resembling World 1-2 from Super Mario Bros., and a Beanstalk at the end. It leads to another warp pipe, which in turn leads to another Checkpoint Flag, and another segment full of mushroom platforms and various enemies, including Bowser, that leads directly to the Goal Pole.
