Ba Sing Se Zoo was originally located in the city. It was moved by Aang to the Agrarian Zone. It is managed by Kenji.
When Aang was flying over Ba Sing Se, he saw a variety of animals who were miserable in their cages. When Aang saw Kenji, the zookeeper, Kenji said the zoo was no longer receiving funds from the Dai Li because it was no longer popular to children. Aang had an idea to move the zoo outside the city, and after some degree of chaos, the animals were relocated to the zoo's new location.
