Okay...this is a secret level
that you can only get through by using the debug mode. If you want
to play it, you need to follow these directions.
After the debug mode has been turned on, go to the boys dormitory
in the Gryffindor Common Room. It is the door to your left (usually
you will find Percy here). Face the door and press delete and up
button until you can see inside the door. Then press delete again
to enter the challenge.
Walkthrough coming soon...
