Ok guys, these are gonna be some pretty serious spoilers, so I'm coloring them to avoid reading if you DO NOT WANT. What these are are medium detail episode summaries. You'll still get full enjoyment out of watching them when they come on, but it is spoilers nevertheless which some wish to avoid for your own reasons. Also, while the research I've done makes these seem legit, you know how the internet is with false info sometimes, so take it with your personal favorite ammount of salt.
(PEE ESS, these are straight copies from the posts of a local source over at Distant Horizon, so any weird language or wordings or focuses arn't my fault.)
TALES OF BA SING SE:
This episode is a bunch of short stories.
1.Katara and Toph go to a day spa and get pampered. Toph gets an “extra strength” pedicure on her calloused (Earthbending) feet. The girls have a mud bending fight while taking a mud bath, etc.
2.Uncle travels around the city collecting things for a picnic. Along the way he inadvertently helps strangers in different ways – he sings to quiet a baby, he helps a mugger get his life on track, etc.
3.Sokka walks past a Haiku club where people are reading haikus. When he accidentally enters the class, he finds out that he has a natural talent for haikus.
4.Zuko goes on a date with a girl that likes him. The two go to dinner and romantically stroll around Ba Sing Se.
5.Aang helps free the animals from a rundown zoo. His plan was to get them all to the agrarian zone in between the walls – a place where they could roam free. But getting them through the city was a bigger challenge than he realized.
6.Momo, looking for Appa, runs into a pack of angry cats. The cats chase Momo through the streets of Ba Sing Se. He tries to hide, acting like a street vendor’s dancing monkey. But the cats don’t let up and continue to chase him.
next up is Appa's Lost Days: (The title isn't confirmed, but seems likely given the details following)
This is an episode where we follow what happened to Appa starting when we lost him in Book 2 Earth Chapter 10.
Appa is taken by the Sandbenders from the library and sold to the Bedouins. Although Appa is tied down, he is hard to control so the Bedouins sell Appa to a traveling Fire Nation circus.
At the circus, a cruel animal trainer “breaks” Appa and forces him to perform in the circus. Appa manages to break free from the circus and goes searching for Aang. Unable to find him, he looks for a place to rest. Appa finds shelter in a barn, but he is violently chased away by a farmer. Still looking for shelter, Appa finds a cave but realizes that the cave is home to another animal – a Boar-q-pine. The two animals have a vicious fight and Appa is injured, stuck with Boar-q-needles. Appa is now becoming more animalistic and it shows when Suki (from Book 1 Chapter 4) comes across him. Appa is like an angry beast and Suki has to calm him down. She and the other Kyoshi warriors take care of Appa but it doesn’t last for long – the Kyoshi warriors are attacked by Azula, Mai and Ty Lee -- and Appa is forced to flee.
Finally we have Lake Laogai: (Also no title confirmation)
In Book 2 Chapter 17 Aang is searching around Ba Sing Se for Appa. He is lead off track by the Dai Li and Long Feng, who actually have Appa and who don’t want Aang to find him. The kids run into Jet who has been brainwashed by the Dai Li – he has information on a secret underground prison – could this be where Appa is? The kids try to deprogram Jet so that they can get the information about the prison from him. Meanwhile, Zuko finds out that Aang is in the city and decides that he is going to find the bison first. So the race to find Appa has begun!
Anyway, there you have it, hopefully I've brought some joy to you spolier seekers
