Answer 1

"Lost Days

Appa became lost for a short while when the group was traveling in the Earth Kingdom. He was kidnapped by Sandbenders in the middle of the vast Si Wong desert, while Aang, Katara, Sokka, and their winged lemur Momo were trapped in a vast underground library.[9] It is later revealed that he was eventually sold to a Fire Nation circus where an animal tamer attempted to make him part of the show.[1] Appa later escaped and journeyed throughout the Earth Kingdom until he encountered the Kyoshi Island Warriors, who attempted to heal the various wounds he had sustained in his travels and escort him back to Aang.[1] Appa was forced to leave after an attack by Azula and her allies, ushered away by Suki while the warriors tried to delay the three Fire Nation girls.[1] On his journey he encountered a sadhu named Guru Pathik at the Eastern Air Temple, to which he had fled.[1] Being healed of his personal turmoil and directed to Aang by the sadhu, Appa flew to Ba Sing Se, where he was captured by Long Feng.[1]

Appa was kept in a secret location at Lake Laogai until his rescue by Zuko, who was initially planning on utilizing him to capture the Avatar.[10] Appa eventually returns to the main group in the last scenes of Lake Laogai." ~ Excerpt from Wikipedia
