Stuck at boo manor

Answer from: Brandy
Go to the room with two couches and a fireplace; it should be next to to coffin room. light up the firplace with hamspar and two old ghosts will appear. tack-q them and they will tech you noknok and pushie. leave the room and go left until you find the hallway withough a door in it. noknok on the wall, and then pushie it. it will open and you can see hamtaro and howdy trapped in a cage. go back to the third floor, and talk to the green hamster trying to open the elevator. he will go and open the cage for you.

to open the coffin, you have to play an win the scrub-e game to get the gold card. then talk to the green and purple hamsters by the elevator again to make them move. go to the fourth floor and find the hallway with a green ghost listening to music. noknok and pushie the wall to go into the hidden room. try and play the piano, and then a ghost will say he can teach bijou to play. he will ask if you'll take a quiz, say yes. he will ask how many questions he's asked you, tell him "1". then tell him the name of the song (moonlight) and the composer (beethoven). go back to the coffin room and play the piano there to make the coffin open. dexter and howdy will be freinds again after that.

hope this helps you :) i had a lot of trouble with this part at first too.
