Bee (Super Mario Land 2: 6 Golden Coins)

A Bībī is a bee enemy in Super Mario Land 2: 6 Golden Coins, found only in the fourth stage of the Tree Zone. When Mario enters their beehive, the bees attack by slowly homing in on him and attempting to sting him. They can be defeated by a jump attack, but fireballs will have no effect. When defeated with a jump, they reappear shortly afterward and will attack Mario again, but can be defeated permanently with a spin jump.

They have an undead subspecies called Skeleton Bees.

Trivia

 * Būichis appear to be giant Bībīs.
 * Bībī have a very similar name to Bunbun from the first Super Mario Land, and may be related.
 * They bear some resemblance to the enemy Buzzer from Super Mario RPG: Legend of the Seven Stars.
