How do you get Ginny Weasley on Harry Potter for the Wii?

Answer 1

I believe you have to retrieve a confiscated potion of Fred and George's in Umbridge's storage behind her office. It's a small little closet behind her office that should contain a trunk (the same one Mad-Eye Moody was trapped in) and a few boxes and at one corner there should be Fred and George's potion. To do this, however, you must return to your common room before and get your invisibility cloak so Umbridge won't see you.

** This is in the Harry Potter and the Order of Phoenix game, to get her to go to the Defense Against the Dark Art Lessons.

If you are referring to something else, then please do not blame or get angry with me but consider rephrasing your question.
