Complete story — includes the ending
After being abducted in the desert, Appa is traded to a Fire Nation circus, where the trainer whips, humiliates, and generally mistreats him. He eventually escapes with the help of a small boy. He later unwillingly fights a Boarcupine, emerging victorious but badly wounded. By fortune, Suki and the Kyoshi Warriors come across Appa and help him recover from his injuries, but the warriors are attacked by Azula, Mai and Ty Lee. Appa is forced to flee at Suki's urging, while Suki's fate against Azula is left unknown. Dispirited, confused, and longing for Aang, Appa returns to his childhood home at the Eastern Air Temple, where he discovers a mysterious guru, Pathik, has taken residence in the ruins. The guru gains his trust and imparts to him Aang's location at Ba Sing Se, with a message for Aang attached to his horn. Appa arrives at Ba Sing Se, but just short of reuniting with Aang he is ambushed and captured by Long Feng, leaving the footprint that Momo found. Note: This episode won a Humane Society award for its portrayal of the mistreatment of animals.
