Notes
This is traditionally made with the cookie crumbs going on first, but we've found that if you are adding the Milano cookie gravestones and PEEP ghosts, it is actually easier to put theses on first and add the cookie crumbs around them. Place the pumpkins and gummy worms on top of the cookie crumbs.
