Several dragonfly bunny spirits, including Bum-Ju, played with Jinora at the Eastern Air Temple. Although the young airbender could see them, the spirits remained invisible to the others until Jinora urged them to appear under Kya's insistence. Bum-Ju and the other spirits led Jinora and her group to the ancient meditation circle away from the temple grounds, where Bumi officially met the spirit and named him. After their brief meeting, Bum-Ju fled along with the other dragonfly bunny spirits after Tenzin performed a spiritual cleansing ritual on the grounds, which attracted a colony of dark spirits from underground.
