When you see an abandoned house in your hometown, what's your first  instinct? Drug dealers? Escaped convicts? Could even be old cat women.  The fact of the matter is, no matter what, it's a house that should  technically never be entered. That, unless, you've lost something,  perhaps a loved one or cherished object, in that house. Even if you did  enter, there is no saying what will happen to you, or you loved one, in  that house, no matter what it is inhabited by. Even so, you may discover  that it could be a haunted house of sorts. If this is the case, this is  not a song that should be listened to before entering that said haunted  house, because chances are, you'll wake up the bigger ones. Yes, you  will awaken the Big Boo! This remix includes songs from both the  original Super Mario Bros. as well as Super Mario World.
