Air Scroll: In the Air Temple (Chapter 6), go west and north after getting out of the
temple. When you get there you will have to play ''The 4 Nations Force'' game with the
spirit of Gyatso. It does not matter if you give up or lose. You will get an Airbending
Scroll. Use it to get a tornado-like attack for Aang (you can move it).

Earth Scroll: In the Air Temple (Chapter 6), go to the south and find the Earthbender.
Talk to him and win the challenge. Then, use the Scroll as done the last time. You will
get a similar move to Haru's Boulder-Kickin', but it will be slower, bigger, and more
powerful.

Water Scroll: In the 4-Paws Island (Chapter 5), go through the middle of the island
and turn upside. You will fight a monster. When you defeat it, it will hide. Follow it
and search for the yellow chest. Enter two key items and use the Scroll. You will get a
water bending power for Katara (revives your friends in battle).
