How do you find Albus Dumbledore in Harry Potter and the Philosopher's Stone for Game Boy Color?

Answer 1

After talking to the Fat Lady, go back down the stairs and talk to Nearly Headless Nick. Nick will tell you that he wants a school tie and then he will tell you the password. To find this tie you must go down another floor and enter the secret passageway, then go down another two floors until you are in the entrance hall. There are two gargoyles here, search the upper one until you get the tie. Take it back to Nick and he will tell you the password.
