Course No.09 is the third course of Mt. Teapot in Wario Land: Super Mario Land 3. The level is abundant with waterfalls, although they don't affect Wario's movements in any way and serve no purpose other than for scenery.
The first cave is a horizontal, watery course where Wario must dodge Helmuts as he makes his way across. Three blocks can be found above the water, with the middle one holding a Garlic Pot. In the second, vertical room, Wario must dodge many Yadorā as he climbs upwards towards the door. After the Yadorā, Wario faces Pirate Gooms in the next waterfall-filled, horizontal cave, located directly above the first room. This area also has a door on a high platform leading to a checkpoint. The fourth room is also vertical, but instead of Yadorā, this area features multiple Penkoons. Wario can collect lines of coins if he falls along the left and right sides of the cave. The next waterfall-covered cave has a secret door hidden behind a half-broken block. If Wario goes through this hidden door, he can find a giant block that holds a 100 Coin. When Wario returns to the main waterfall room, he must cross the rest of it to find a door to the last area. In the final area, there are two Konotako and the course's exit.
In the hidden room with the giant block, there is a treasure room door located on the other side of some breakable blocks. The key to the treasure room is found inside the block on the right side of the third waterfall room. The treasure is a harp worth 6,000 coins.
