I was replaying the game for the fifth time (because this game has ended up taking up all of my interest), and in the first level, 1997, I set every item in one large group, and I noticed before I started neatly putting the items away, the level was finished! But not in the traditional way. Instead of being gold and playing a high pitch jingle, the star was black and was low and relatively ominous sounding.
What is going on?

I am in the middle of doing this, but even though I piled everything on the floor (Stage of moving in with her friends) I can't get the black star FOR THE LIFE OF ME. First two levels fine, but I'm stuck on the third.
