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 Area 4 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.
