Bending Introduction: Sandbending (assumed to be a form of Earthbending)
Originally aired as a two-part special called "The Fury of Aang".
(While the group is searching for the library)
Toph: (looks up; excited) there it is!
(Sokka and Katara look to where she is pointing and see nothing)
Toph: That's what someone will say when we find this place (waves hand in front of her face to remind them that she is blind).
Katara: You've been hallucinating off cactus juice all day and then you just lick something off the side of a cave!?!
Sokka: I have a natural curiosity!
