So while rewatching Avatar: The Last Airbender recently, I noticed a trend
A number of spirits we see have an animal form, specifically animals we recognize as "normal" for us. For example:
- Wan Shi Tong is an owl and his knowledge seekers are foxes
- Tui and La are koi fish
- Hei Bai is a panda
-The guardian of the mother of faces is a wolf (The Search)
Heck there's even the talking Baboon spirit and the monkey missing its face that we see in the Spirit World at the end of Season 1.
Basically every time we've seen a "normal" animal, they've been a spirit.
My point? I argue that Bosco is a spirit bear that's chilling and living the good life in the mortal world just because he can.
Don't forget Miyuki!
