Met with the hazards of pollution, the gang must save the planet from an enemy far more versatile than Fire Lord Ozai. Fire Nation war machines are creating a world of smog, and it is Team Avatar's job to clear the air.
All actions can be performed through the use of the left mouse click.
Katara is capable of planting seeds that reinvigorate the oxygen. To do so, one should click on a seed of appropriate coloration and subsequently click an area of dirt that is adjacent to smog that matches the seed's pigment. Doing so will lead to a dirt patch clear of smog. However, it will also sometimes result in a patch of dirt with a specific color. This means that only that color seed can be planted in that dirt.
Furthermore, planting a seed in dirt that is adjacent to a differently colored smog will result in the partial removal of that smog. To completely remove the rest of the smog, one must plant a seed of identical color next to that smog per previous instructions.
Oftentimes the removal of smog uncovers a war machine that was hiding within the fog. Aang, Sokka, and Toph can be called upon to destroy war machines and keep the soldiers from further damaging the ecosystem. This can be done by clicking on any of Katara's three friends, then clicking on the war machine that is to be destroyed. Depending on which friend is employed, a different color of smog will appear in place of the machine; Aang creates red, Toph yellow, and Sokka blue. Each friend can be used only once per level.
Rocky patches of dirt are barren and unable to be touched.
