OK this may not be a Hack since I just bought everything and put it together, but you could take it a step further and hack the Witch so she speaks your microphone input or custom recorded messages, etc. The combination of the moving jaw, the bobble-head, and the flowing cape and hair make this Witch amazing to watch cackle around in the moonlight at about 4 mph. This Witch is just plain creepy, even to adults (or so I'm told, by adults). Her LED eyes light up red, but it might be better to highlight her mouth with some type of light so you can really appreciate the fact that her jaw moves to the dialogue at night. The bobble-head whips left/right as you turn and bows as you stop short, adding life to an otherwise static figure. There is a lot of potential for hacks, but right out of the box it is bewitching. Sorry for the portrait video, I was one-handed.
Don't disparage yourself -- this is *absolutely* a hack!
