I Can't Wait to be Queen[]
During Duties of the King, it is menitioned that one of the king's duties is the ceremoinal naming of the bees, while Simba sings about this, a swarm of bees fly close to their hive. They momentraily move an flyaround simba's head.
After Ono reports that the bees are creating new beehives along the path that the elands are traveling along, Queen Kiara sends the Lion Guard to divert the elands away from the bees. However, the leader of the lion guard, Kion, instead decides to move the bees rrather than the elands. This results in a swarm of bees pursuing the Lion Guard and attacking them after the Guard collides with the eland herd. Bunga, however, is not bothered, and eats honey from one of the hives while bee fly around him.
