Būichi (ブーイチ) is a bee enemy found in the Tree Zone in Super Mario Land 2: 6 Golden Coins. If Mario goes near to this enemy, the Būichi will drop down until it hits the floor, and then fly back up to its position, very similar to Thwomps. With the exception of a Super Star, nothing can defeat them.
