Ask the detention room supervisor for a key. Or ask Bill to do it. He was picked up last summer for a few B&Es.
You have to make that smelly bomb or in the science room after you chew gum and get in troble for it and go in detintion you open it up so that the teacher gets out Hope this helps! Good Luck! :)
The boiler room. you get there by going into the Town. Then go into the night club. in one of the speakers, if you put your cursor over one of the speakers ( I'm not exactly sure which one but i think it's the 4th from the left) it should open then go down the ladder hidden in the speaker and you will be in the boiler room. you can also get there by going into the Plaza and going down the manhole. then go to the room on the left of the pool when your underground. anyway, when your in the boiler room, there should be a file cabinet in the top left of the file cabinet, if you put your cursor on the top left of the file cabinet, it should open up, then if you click on the open file cabinet there should be a bunch of newspapers you can read if you click on them.
Click the locker again and you will get a map of the school, revealing a secret room under the file cabinet.
They are in detintion either for chewing gum or other
make a stink bomb finish comic get gum chew it in the school go into the detention room release the stink bomb and go in the file cabinet.
You can't access the Filing Cabinet unless you have the Blueprint showing where the secret room is. Use Nate's combination to open his locker, and get the blueprint from the pile of papers. Now you can access the room below the filing cabinet.
A mobile file cabinet can be easily moved from room to room. This is particularly useful in office that must share one set of paper files between many people.
You have to have the map of the school to open the cabinet and go down to the room with Arthur. Then you jump up to get the clapper for the school bell.
ope the locker with combination 9305 and then click on the filing cabinet
In the file cabinet, in detention, in the school.
You get to it by using the stink bomb you made in the science lab.
Go inside the file cabinet, go down to the secret room, and get the bell clapper. Before you go to detention, you have to open Nate's locker and get the blueprint showing the secret room.
