Halloween Cat Lawn Decorations

What can I do with a refrigerator box for my front yard? Creative people & Halloween fanatics please respond!?
I was lucky enough to get my hands on a refrigerator box to use for my outside decoration. Please don’t suggest I cut up this great big box into little tombstones or something small because that would be a waste of a great box. I have plenty of smaller cardboard boxes to work with also.
My front yard decorations are as follows: a jack-o-lantern tree, a giant spider attacking a dollhouse, a cremation wall out of the garage door, a giant jack-o-lantern paper mache hot air balloon with a black cat in the basket and various lights including rope lights that spiral on the lawn in a Tim Burtonesque way.
I don’t want to do anything gorey (I’m gearing my decorations to young kids) and I don’t want to make a coffin. I was thinking I could construct something the kids could walk through, like a classic looking haunted house or clocktower. What are some ideas?
I think you should decorate it like a casket. Then have a friend dress up like a dead person, Dracula or Zombie. Have them lay in it as still as they can. Then when someone comes by, rise up and scare them. Shine a green or red spotlight on it for effect. Maybe just put it on your front porch if you have one to keep it out of the weather. Could also stand it on end and decorate as a mummy case. Embellish with another box on top to give it a more authentic look. Have someone stand in it in mummy attire. Again, they can walk out of it and scare people.

You’ll need:
All white shirt and sweat pants
First aide gauze rolls
Face paint
Instructions:
Paint your face totally white and then add some green and black around the eyes. Wrap the gauze around your head and neck, not too tight, until only your face is showing. Add a scar and blood to your face and some blood on the gauze. Randomly add gauze and blood around your body and limbs.
