I like it. Please share in the props section too. More people who are looking for props may see it there, and might not come to the General Halloween section much.
LOL. Good job with the "similar videos" algorithm! By simply adding "book case" to "panel drop", it gets completely confused and instead of getting links to more halloween vids, all I got was links to news stories and book reviews.
You could always paint some book spines, vases or candelabra on the drop panel. They would probably blend in enough to look like props for the few moments that they approach bookcase.
