How do you get into the library in Avatar the Last Airbender game for DS

First you need to go to the front entrance, then turn right and then up to get to the back of the building. Next, you need to search the back until you find the back door. It will be locked. Then you need to make Momo go in through a vent to unlock the door, Haru will stay behind and wait for you, You then go down then left, and there will be another door. open it. then walk straight and you will find another door. open that and you will find yourself alone. hide behind the bookcases so u wont be caught. oh... never run. always walk while u r in the library so you make quieter sounds. pull out the map and go to the bookshelf that is closet to the next room. find a door. go through, and you will find yourself with katara and sokka again. there you can change players. open the next door and you will see another room. do the same thing. when you get to the next room, there will be a map. someone will then say..."Hey!" "is someone in there!" you will then crawl out of a vent, you then go talk to king bumi. Good luck!
