Mary O.'s Key Course
From the Super Mario Wiki
Mary O.'s Key Course (known as Key Door Course in the European version of the game) is Mary O.'s seventh official course in Super Mario Maker, released on March 16, 2016. It is set in the ghost house theme and in the Super Mario Bros. game style. This level is reworked into Coo! (Yamamura's Key Course).
The level begins with some Dry Bones and a Mystery Mushroom. The first Key is located in a group of winged Circling Boo Buddies, which Mario can open a Key Door with. Afterwards, Mario should enter a Warp Door, and take out a winged Stretch to obtain another Key. Mario must then reenter the Warp Door, hit a ? Block containing a Beanstalk, then go up it and enter a warp pipe to reach another Key Door. Afterwards, Mario must collect some Pink Coins, hit a P Switch to enter a P Door, then go through the warp pipe on the left and open another Key Door to be led directly to the Goal Pole.
