Serpents Pass

Serpants pass is unforgiving pass that a huge serpant lives in. Aang, Sokka, Katara, Suki, Toph, and a couple with a baby on the way cross this. They were desparate and wanted to go to Ba-Sing-Se. On their way they run into obsticles, like the strech of land broke and Katara used her water bending to save everyone.
