How do get Anngs Last Move the Tornado and Kataras Last move Healing?

I don't know about the Tornado, but Katara's healing move is learned by using the water scroll found on the four paw island. You need to open the key item chest, select the water scroll, and then select use. Trace the scroll as the game shows, and katara will learn the healing move. It is only used to revive a character who went down to 0 HP, and it fully revives them. Hope this helped.

I think you have to get Aang to lvl 20 to learn the tornado

Wait I believe there is a scroll after chapter 7 that learns the tornado

This how to do it:
Katara's healing move is not her final for starters. I got it as her second. Anyway, on four paws island, there is a path trough the island. Go through it.

Around halfway there or so, there is a path that brances north. Go there. You will get ambused by a big monster. Everyone except aang will hide. You will have to use aang and fight him (I recommend air scooter). When you win, go north. There are 3 bunches of bannanas and katara's scroll.

Aang's move is at the air temple. After Katara, Sokka, and Haru are caputured by something, you play as aang again. Get out of the temple. You will go to the marketplace. Go to the northeastern path. There is a place on the northern forest path that looks like a shrine. Go there and aang will by agenst monk gyatsu... And lose. You will get the scroll either way

U have to find a monk named Gyasto near the town in Chapter 6 and play that game and regardless if you lose or win I think you get the scroll anyway

This is how I did it I bought the acition replay ds at walmart for $19.85.
It gives you starter cheat codes andd you just mark the ones you want it keeps you fuuly healed , infinite money , and it works on more than one game.

I believe you should find gytso that has the air scroll if you go all the way north then go
