Course No. 6
Course No. 6 is the secret course of Rice Beach in Wario Land: Super Mario Land 3 that is only accessible by finding the secret goal door in Course No. 3. It is the shortest level in the game, and merely serves as a "bonus" area where Wario can earn more coins than usual and no enemies are found.
Wario starts in a room with a block holding a Bull Pot and a door leading to a beach area. In this area, multiple Maizō can be seen hidden beneath the sand, which can be forced out with a Ground Pound and defeated with Wario's body attack. Each Maizō holds a 10 Gold Coin and will flee if left out of the sand for too long. Coins are also found suspended above the sand, as well as invisible blocks holding hearts. The goal door is found at the end of this area.
