As the Fire Nation girls discussed the losses that would result from Bumi's release, the king nodded in approval.The deal was not passed, and Bumi was again lifted to the air.Upon Aang's successful completion of the first test, Bumi administered the next test, which involved finding Flopsie, the king's pet, and bringing the animal to him.
Bumi carried himself with the same composure during a quiet, peaceful meal as he did when his city was under attack and he rarely explained his actions, which tended to infuriate his subordinates. As a child, he became close friends with Aang, showing him how to use the Omashu delivery system as "the world's greatest super slide", which caused the young airbender to label Bumi as a "mad genius".
Bumi's eccentricity arose out of the fact that he always kept his mind "open to the possibilities".
As a child, Bumi decided to use the Omashu delivery system as a chute ride, for which Aang dubbed him "a mad genius", a name that Bumi seemed to appreciate.
He was interrupted by an impatient Aang, who wanted to proceed to the third and final challenge.
King Bumi informed the airbender that the last test would be a duel and asked Aang to choose his opponent.
