Bat Course

Kōmori Kan Course is the first level of the Pumpkin Zone in Super Mario Land 2: 6 Golden Coins. This level takes place through a graveyard, although the majority of the level is set in an underground structure. According to the Perfect Ban Mario Character Daijiten, the building was built long before people lived in Mario Land, and that the Kurokyura is the building's master.

Layout
The level starts out with a J-son and a ? Block containing a Mushroom, with a pipe which takes Mario underground. Here, there are several Tōsanbōru, spike balls attached to chains which move up and down, as well as a few more J-sons. There are also four ? Blocks, the third one containing a Carrot Mario can use to become Bunny Mario. After the ? Blocks is a pipe which takes Mario to an area above-ground. If Mario chooses to stay underground, he will encounter falling spikes, another J-son, and a Fire Piranha Plant. If Mario chooses to enter the pipe, he finds himself in an area with two Boos and many fading blocks which turn invisible. Mario can stand on them even when they are invisible. At the top are three ? Blocks, the one in the middle containing a 1-Up Heart. Mario can then enter the other pipe leading back to the underground section, taking him directly to the Mid-Point Bell.

Mario must then make it past several more obstacles until he reaches Kurokyura, who can be defeated with a simple jump. Mario can also bounce off one of his bats to reach a ? Block which contains another 1-Up Heart. He is then able to reach the goal.
