The very first episode of the series. Well, technically two
The Boy in the Iceberg
An Avatar's best friend
Flying Bison
Known for its vertical architecture and delivery system of chutes and slides, this city is ruled by the eccentric King Bumi
Omashu
This one's a freebie. Just give me the name of Aang's Flying Bison
Appa
I feel very conflicted about wrestling a small blind child
The Boulder
You drive a hard bargain, perhaps you'll accept two copper pieces
The Waterbending Scroll
King Bumi had this very unusual pet. Well, unusual for the Avatar world
Bear
There is no war here I can assure you
Ba Sing Se
It appears I've lost my beloved pet. Aang, can you please help me retrieve him? This will be your second challenge
Flopsie
OMG that guy has rabbies! Wait, no he doesn't. He's just overwhelmed by Aang's impressive airbending display
Foaming Mouth Guy
Look at that Lemur, its earthbending!
Imprisoned
This kind of bear can lay eggs? Maybe it's a special agent

Fire Nation prison surrounded by water. I wouldn't go in there if I were you
Boiling Rock
Korra's best friend
Naga
This Earth Kingdom refugee and talented engineer lived at the Northern Air Temple, where he used the temple's natural hot springs to power his inventions. Wait, he's working for fire nation!?
The Mechanist
Ah yes, we can infiltrate the fire nation by attending school? Well at least I can show them how to dance
The Headband
Zuko gets bitten by this cuddly little reptile waterfowl thing? Man, it's hard describing these weird animals

Nyla
The fortune-teller from the village of Makapu who predicts that Katara will marry a "powerful bender."
Aunt Wu
Of course, Sokka would find a way to get stuck in a hole. At least he made a new friend. Just ignore the fact that he wanted to eat him at first
Bitter Work
No wonder the swamp people were trying to eat Appa. They were probably sick of eating this aquatic reptile. At least I think it's a reptile
Catgator
In the episode "The Beach," the Fire Nation teens spend their vacation at this specific island resort owned by Lo and Li. Don't they have a theater?
Ember Island
Finally, Sokka has a friend. How could he afford him you ask? Well, we don't talk about that
