Bum-Ju

Bum-Ju, or Bumi Junior, is a dragonfly bunny spirit who befriended Bumi in the Eastern Air Temple.

History
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.

Bum-Ju reunited with Bumi following Avatar Korra's defeat of Dark Avatar Unalaq during the Harmonic Convergence of 171 AG. Soon after, the two witnessed the Avatar address the Southern Water Tribe to announce the end of the Water Tribe Civil War and happily listened as she declared her decision to keep the spirit portals open. Soon after, Bum-Ju traveled with Bumi to Air Temple Island and fled from the retired commander when he attempted to dress him with a pink sweater. Bum-Ju attempted to keep Bumi from falling off a cliff in his attempt to reach the spirit, but was unsuccessful, witnessing as Bumi fell and began to airbend.
