Busy Bee

Busy Bees are small insect monsters that only appear in the Sky Palace. They are rather common enemies in this location and often fly diagonally towards Pit. However, if he gets too close to one, the Busy Bee will quickly change its flight pattern and begin circling Pit until it hits him.
