Animated, Moving Halloween Cake

This is a Halloween cake that I made for a kids Halloween party at my husbands work. It's got moving hands in the graveyard, spinning bats on top of the house, strobe lights inside the house, flashing red eyes in the haunted tree, a light up yellow moon, lighted pumpkins, and lighted skeleton torches. It was a really fun cake to make!! The cake consisted of 9 layers of full sheet cake. The final size was 4' x 2'. Yellow cake with a cookies & cream filling. Most was covered in buttercream, but some parts had fondant & gumpaste accents.
