Other mistake: When Azula attacks The Western Air Temple, there is a close up shot of her when she says that she is about to become an only child. Pay attention to the smoke coming from the airship behind her, especially above her head: it doesn't move. Even if this was remotely possible, it does move when the camera zooms out, making it a mistake nonetheless.
The Western Air Temple - S3-E12
Other mistake: When Sokka and Aang put Toph's feet into the fountain, Aang's hand (the one holding Toph's left leg) is incorrectly drawn with a blue glove on it. The glove is gone in the next shot. (00:15:29)
Other mistake: When the group is first shown inside the store, Sokka starts running forward. Toph stands behind Sokka, but as Sokka is running away from them, she is layered over him. (00:04:43)
The Firebending Masters - S3-E13
Other mistake: When Ran and Shaw (the dragons) breathe the colorful fire around Aang and Zuko, and the camera moves down to them, Zuko's scar is on the opposite side of his face, and his sword and Aang's clothing are worn over the opposite shoulders in a mirrored shot. (00:20:01)
The Ember Island Players - S3-E17
Other mistake: When they are watching the recap play Toph says she can't see it because they are on a balcony, but when her character comes on she describes him as buff.
Suggested correction: She didn't see him (or technically, feel him), but she heard him. The actor playing her character throws the huge prop rock, and it hits the stage floor. Then, he flexes his muscles. Toph heard all this happening from her seat and then said, "I sound like a guy. A really buff guy."
