You got in trouble and you were sent to your room by your mother. She asks that you decorate the room before she will let you out, so that is what you must do. Use your mouse to move around the room. On the door you will find a list of all the things you need to decorate the room with before you can get out. Grab all the items that are strewn about the room and put them on the tree or fireplace, or wherever they go, but by all means - get out of that freaking room! You will go stir-crazy if you don't make it out so hurry up and do as you're told!
