This boy, along with Aang, was among the children who went to the Eastern Air Temple to choose a flying bison, their companions for life.[2]
He was also present when Aang taught his friends an airbending trick called the air scooter, and was the first to try. He successfully created the scooter, but fell on his back when he attempted to ride it. After practicing for some time, he finally mastered the trick and even created a game with his friends; however, when Aang came to play with them, the boy told him he could not, saying that him being the Avatar meant his team would carry an unfair advantage. This exclusion from his friends prompted Aang to sadly walk away, while this boy then asked the others who wanted Jinju on their team.[1]
