Halloween 2011

Every year I make Halloween boxes for my grandsons.  Usually it is a big one that is real interactive.  This year my daughter informed that the boys were really looking forward to the box I was going to create this year.  Needless to say, I had not planned on making one, but now I have created a tradition.  Is this how they start?

They light up from the back and the little ghouls scream when you push their stomachs.  They are both about 6" tall, so I didn't worry much about what to put in them. 
They haven't seen them yet, but soon and I hope they like them.
