Avatar Book 2 Earth Episode 4 - The Swamp Episode Title:The Swamp.Episode Description:While flying, Aang and friends are attracted to a mysterious swamp and get separated from one another. They begin to see unique illusions in the swamp: Sokka sees Princess Yue, Katara sees her dead mother, and Aang sees a mysterious girl and a flying boar. They are reunited and attacked by a swamp monster who turns out to be a wise man from a tribe of swamp waterbenders who use the moisture inside the swamp's plants to manipulate the plants and hide their identities. He explains that all beings are connected, as the swamp is a single large tree, and the visions are of people they have met or will meet. Meanwhile Zuko, disgusted with having to live as a beggar, dons the mask of the Blue Spirit once again.
